Berkeley, Mountain View, Pasadena, and Richmond in 2026 — the four California rent-control overlays that all chose February 1, 1995 as their Costa-Hawkins cutoff

Four California rent-control ordinances arrived independently at the same first-certificate-of-occupancy cutoff date: February 1, 1995. The date is not a coincidence. It is written into Cal. Civ. Code §1954.52(a)(1), the Costa-Hawkins Rental Housing Act — the state law that prohibits California cities from controlling rents in units whose first certificate of occupancy was issued on or after that date. Berkeley BMC Chapter 13.76, Mountain View CSFRA Charter Article XVII (Measure V, 2016), Pasadena Municipal Code Chapter 8.71 (Measure H, 2022), and Richmond Municipal Code Chapter 11.100 (Measure L, 2016) each drew their coverage boundary exactly at the Costa-Hawkins floor. In 2026 those four ordinances produce four different caps — Berkeley ≈ 1.0%, Mountain View ≈ 1.7%, Richmond ≈ 1.7%, Pasadena ≈ 2.25% — from formulas ranging from 65% × SF Bay Area CPI (Berkeley) to 100% × SF Bay Area CPI (Mountain View and Richmond) to 75% × LA MSA CPI (Pasadena), with banking models that range from Berkeley’s unlimited accumulation to the per-notice-ceiling bands of the other three. All four are voter initiatives. We walk each ordinance’s formula, banking rule, first-CoC history, and preemption landscape side by side.

Quick orientation: the four Costa-Hawkins-aligned overlays

The table below summarizes the key parameters for each of the four ordinances as of 2026. All four share the same February 1, 1995 first-CoC cutoff and all four are voter-enacted. Beyond those two shared features, the formulas, CPI anchors, banking models, and administering bodies are structurally different.

Two entries in that table stand out immediately. First, Berkeley was enacted in 1980 — fifteen years before Costa-Hawkins was passed. Its February 1, 1995 cutoff is the result of a post-enactment amendment to comply with state law; the original 1980 ordinance had a different (and broader) coverage scope. Second, Pasadena uses the LA-Long Beach-Anaheim MSA CPI rather than the SF Bay Area CPI used by the other three. Despite Pasadena being geographically in the LA metro, its 75% × LA-MSA formula produces a higher 2026 AGA than Berkeley’s 65% × SF-MSA formula because the LA MSA CPI ran materially higher than the SF MSA in 2025. Those structural differences are explored in detail below.

Why February 1, 1995? — the Costa-Hawkins Rental Housing Act anchor

The Costa-Hawkins Rental Housing Act, Cal. Civ. Code §§1954.50–1954.535, was signed into law on February 1, 1995 (hence the date). The Act establishes three categories of units that are exempt from local rent control, overriding any city or county ordinance to the contrary:

1. Post-February 1, 1995 first certificate of occupancy (§1954.52(a)(1)): Any residential dwelling unit in which the first certificate of occupancy was issued on or after February 1, 1995 is exempt from any local rent-stabilization ordinance. The landlord may charge and increase the rent to any amount. This is the provision that creates the shared cutoff date for Berkeley, Mountain View, Richmond, and Pasadena.
2. Single-family residences and condominiums with HHBO notice (§§1954.52(a)(2)–(3)): An owner-occupied residence or a condominium may be exempted from local rent control if the landlord serves the statutory “Homeowner and Homeowner’s Exemption” (HHBO) notice at the commencement of the tenancy. The four ordinances in this post all apply these SFR and condo exemptions from their own coverage provisions, consistent with §1954.52.
3. Vacancy decontrol (§1954.53): Upon voluntary vacancy, abandonment, or lawful eviction, the landlord may establish a new rental rate for the incoming tenant at any amount. The local ordinance then governs how much that initial rent can be increased during the new tenancy — but it cannot control what the initial rent was set to. All four ordinances comply with vacancy decontrol.

The February 1, 1995 provision in §1954.52(a)(1) operates as a bright-line preemption: no city attorney, Rent Board, or administrative hearing officer can interpret a local RSO to cover a post-1995 unit without the ordinance being immediately preemptible by state law. Any landlord served with a rent-increase limitation on a post-1995 unit has a clear statutory defense under §1954.52(a)(1).

For Berkeley, Mountain View, Richmond, and Pasadena, drawing their coverage boundary exactly at February 1, 1995 does more than comply with state law — it demonstrates legislative precision that makes each ordinance harder to challenge on preemption grounds than an ordinance with a vague or overlapping coverage definition. None of the four tries to cover the “penumbra” of near-1995 buildings. The cutoff is binary: first CoC before February 1, 1995 means covered; first CoC on or after that date means Costa-Hawkins-exempt.

The coverage consequence for landlords

If a landlord cannot determine the first certificate of occupancy date for a unit in one of these four cities, the operative question is which side of February 1, 1995 the unit falls on. The standard sources for first-CoC dates are:

• The local building department’s permit records (available over the counter or via online permit portals in all four cities). The first Certificate of Occupancy is a dated document in the permit file.
• County assessor records, which often record the year the structure was built (though “year built” assessor data can reflect remodeling dates and is less reliable than the permit record for identifying the first CoC specifically).
• The local Rent Board’s registration records. Berkeley, Mountain View, Richmond, and Pasadena all require landlords to register covered units; if a unit is registered, it is covered. If a unit is not in the registration database, it is presumptively exempt (though unregistered covered units do not escape liability — they remain covered and the landlord faces registration penalties on top of any overcharge liability).

For units near the February 1995 date — first CoC issued in 1993, 1994, or early 1995 — the permit record is the authoritative source. A first CoC dated January 31, 1995 is covered by all four ordinances. A first CoC dated February 1, 1995 is one day outside the coverage window; under §1954.52(a)(1), the exemption applies to units first occupied “on or after February 1, 1995.” February 1 is exempted, not covered.

Three paths to February 1, 1995: how each ordinance got to the same date

The four ordinances did not choose February 1, 1995 simultaneously or in coordination with each other. They arrived at the same date through three structurally different processes spanning four decades:

Path A — Berkeley (1980): enacted before Costa-Hawkins, amended to comply afterward

Berkeley’s Rent Stabilization and Eviction for Good Cause Ordinance was enacted by Berkeley voters on June 3, 1980 as a charter amendment, codified at Berkeley Municipal Code Chapter 13.76. The 1980 ordinance predated the Costa-Hawkins Act by fifteen years. In 1980, no state-law ceiling on local rent-control coverage existed; the City of Berkeley could, and did, enact a framework covering its entire rental housing stock without restriction.

When Costa-Hawkins was signed on February 1, 1995, it immediately preempted the portions of the Berkeley ordinance that reached post-1995 units — but in 1995, no buildings with first CoC on or after February 1, 1995 yet existed in Berkeley (the effective date was prospective). Over the following years, as new construction was completed and new buildings received certificates of occupancy dated after February 1, 1995, the Berkeley ordinance’s text had to be reconciled with the Costa-Hawkins exemption. Berkeley amended its coverage definitions to explicitly exclude post-February 1, 1995 first-CoC units, aligning the ordinance text with what §1954.52(a)(1) required.

The result today is that BMC §13.76.050(a) states the ordinance covers “rental units for which the first certificate of occupancy was issued prior to February 1, 1995” (combined with the standard SFR and condo HHBO-notice carve-outs). Berkeley’s path to February 1, 1995 was mandatory compliance — the date was forced on the ordinance by state law, not chosen by the city.

Path B — Mountain View and Richmond (2016): enacted after Costa-Hawkins, built to comply from day one

Mountain View Measure V and Richmond Measure L were both passed by voters on November 8, 2016 — the same day, in two different counties (Santa Clara and Contra Costa), during the height of the Bay Area housing crisis. Both measures were written by local advocates and city attorneys who had lived with Costa-Hawkins for 21 years and designed their ordinances to comply with it from the start.

Mountain View CSFRA Charter Article XVII §1702(b) explicitly excludes “a rental unit that received its first certificate of occupancy after January 31, 1995” (equivalently, on or after February 1, 1995). Richmond Municipal Code Chapter 11.100 §11.100.030(B) similarly excludes post-January 31, 1995 units from coverage. Both provisions were written with the exact language of §1954.52(a)(1) in mind; there was no post-enactment amendment process required.

For Mountain View and Richmond, the February 1, 1995 cutoff was a deliberate design choice — chosen to maximize coverage under state law (covering all units that Costa-Hawkins permits, and no units that it doesn’t), avoid any preemption challenge on scope, and create the broadest legally defensible protection for tenants in pre-1995 housing stock. Both cities had seen significant pre-1995 rental stock appreciating in value during the tech boom of 2012–2016, and their voters were specifically targeting the older multi-family buildings where long-term tenants were being displaced.

Path C — Pasadena (2022): enacted 27 years after Costa-Hawkins, designed from first draft with the February 1995 date baked in

Pasadena Measure H passed on November 8, 2022, during a post-COVID rent-surge environment that had pushed Los Angeles County rents to new highs while the statewide eviction moratorium was winding down. The Pasadena measure was drafted by tenant-advocacy attorneys for whom Costa-Hawkins’s February 1, 1995 provision was not a legal constraint to navigate but a settled fact of California housing law that had been litigated and confirmed for more than two decades.

Pasadena Municipal Code §8.71.010 (coverage) explicitly limits the RSO to units “for which the first certificate of occupancy was issued prior to February 1, 1995.” There is no ambiguity in the coverage language, no pre-1995 ordinance history to reconcile, and no post-enactment amendment process. Pasadena is the clearest example of a California RSO that was designed to comply with Costa-Hawkins from its first draft.

Pasadena’s 2022 enactment was also geographically notable: it was the first voter initiative RSO in the Los Angeles County San Gabriel Valley corridor since the 1980 wave. The cities of Glendale and Burbank — Pasadena’s neighbors — have no local RSO and are governed only by AB 1482 at approximately 8.0% for 2026. The cross-boundary disparity (Pasadena pre-1995 building at ≈ 2.25% vs. adjacent Glendale or Burbank pre-1995 building at ≈ 8.0%) is one of the sharpest adjacent-city rent-cap gaps in Southern California, driven entirely by whether the city passed a local RSO.

Berkeley BMC §13.76 — 65% × SF MSA CPI, unlimited banking, the pre-Costa-Hawkins ordinance

Berkeley’s framework under Berkeley Municipal Code Chapter 13.76 and Rent Board Regulation 1271 remains, after more than four decades, the most tenant-favorable rent-cap structure in California by any banking-recovery metric. Its formula is the most conservative of the four (65% multiplier), its annual AGA is consistently the lowest of the RentCeiling catalogue (~1.0% for 2026), and its banking model is the most permissive (unlimited accumulation with no per-notice or per-year ceiling).

The AGA formula

The formula is established by Rent Board Regulation 1271:

AGA = 65% × CPI-U, San Francisco–Oakland–Hayward MSA, July 1 to June 30 reference year, as published by the U.S. Bureau of Labor Statistics
Maximum annual AGA: 7.0% — the formula output cannot exceed 7.0% regardless of the CPI reading. At 2026 CPI levels approximately 1.6% for the July–June period, the formula produces approximately 1.04%, published by the Rent Board as 1.0%.

The 7.0% annual ceiling on the AGA formula has never been binding in the period covered by the RentCeiling catalogue. It would require the Bay Area CPI-U for a July–June period to exceed approximately 10.8% (65% × 10.8% = 7.0%) before the ceiling would apply — a level not reached in recent decades, though the ceiling serves as a structural backstop against future high-inflation scenarios.

The Rent Board publishes the AGA for each rent year (which runs approximately July 1 to June 30 for most Berkeley tenancies) in the fall of the preceding year. The AGA for Rent Year 2026–27 is approximately 1.0%. Landlords should confirm the exact published figure with the Rent Board before serving any notice, as the officially published figure controls; the RentCeiling calculator reflects the most recently published Rent Board AGA.

Berkeley coverage: February 1, 1995 first-CoC and the standard carve-outs

BMC §13.76.050(a) covers multi-unit residential buildings with first CoC before February 1, 1995, subject to the standard Costa-Hawkins carve-outs:

• SFR exemption: A single-family home where the landlord serves the statutory HHBO notice at lease commencement is exempt from the rent cap (though Berkeley’s just-cause protections under §13.76.130 may still apply to SFRs — the rent cap and the just-cause regime have different coverage rules in Berkeley).
• Condo exemption: A condominium where the landlord serves the statutory HHBO notice is exempt from the rent cap. Condominium conversions completed after June 1977 (Berkeley adopted a conversion moratorium) are an additional category.
• Owner-occupied two-unit buildings: Certain owner-occupied duplexes are partially exempt.
• Subsidized housing: Units covered by certain federal or state subsidized housing programs where the rent is regulated independently are exempt.

Berkeley’s February 1, 1995 cutoff means it covers the broadest permissible share of its rental housing stock under state law — reaching all buildings first occupied through January 31, 1995 that are not otherwise exempted. Buildings constructed between January 1983 and January 1995 are covered by Berkeley’s RSO but not by Oakland’s RAP (which has a December 31, 1982 first-CoC cutoff) — a coverage divergence that matters for landlords with units in both cities.

Berkeley banking: unlimited accumulation under §13.76.110(C)

Berkeley uses what the Rent Board calls the rent-ceiling accumulation model: each year, an AGA is published and the legal maximum rent (the “rent ceiling”) for each covered unit rises by that AGA, regardless of whether the landlord actually serves a notice or collects the increase. If the landlord serves no notice in three consecutive years, the rent ceiling has accumulated three years of AGAs. Those accumulated amounts can be collected in a single properly-noticed increase at any future point, with no per-year ceiling and no per-notice ceiling on the banked amount.

The only gate on collecting a banked balance is the AGA-denial gate at BMC §13.76.110(B)(2), which requires the landlord to satisfy all four of the following conditions before serving an above-AGA or banking-recovery notice:

1. The unit must be currently registered with the Berkeley Rent Board (registration is annual and requires payment of the Rent Board service fee).
2. The landlord must be in compliance with all outstanding Rent Board orders affecting the unit.
3. There must be no substantiated habitability violations recorded for the unit with the Rent Board or any other code enforcement body.
4. The landlord must be current on all annual security-deposit interest payments to the tenant, as required by Berkeley’s interest-on-deposits rule.

If any one of the four conditions is not met, the landlord cannot collect the banked balance at that time — but the balance does not disappear. It remains accumulated in the rent ceiling and can be served once all four conditions are satisfied. An eligibility-deferral provision at §13.76.110(B)(1) may further delay when the accumulation counting begins for certain newly-covered units.

Berkeley’s banking is fundamentally different from the per-notice-ceiling models used by Mountain View, Richmond, and Pasadena. There is no number — not 8%, not 10%, not 15% — above which a Berkeley landlord cannot serve a single banking-recovery notice. A landlord who owns a Berkeley unit, never increased rent for a decade, and now satisfies all four AGA-denial gate conditions can serve a single §827(b) notice collecting the entire accumulated balance (ten years of AGA increases), provided the balance is correctly calculated against the published Regulation 1271 AGAs for each relevant rent year.

Berkeley governance: the elected Rent Board

The Berkeley Rent Stabilization Board is a ten-member body: five members elected directly by Berkeley voters in contested district elections and five members appointed (four tenant-nominated, one landlord-nominated). The elected composition gives the Rent Board a democratic accountability mechanism not present in appointed-only bodies like Mountain View’s Rental Housing Committee. The Board sets AGAs, promulgates implementing regulations, hears petitions for individual rent adjustments (landlord-petition-for-above-AGA and tenant-petition-for-rent-reduction), issues compliance orders, and enforces the ordinance.

The Board’s elected structure also means that policy changes — such as shifts in the AGA formula multiplier, the introduction of new exemptions, or modifications to the banking rules — require either a charter amendment (voter approval) or a regulatory change by the Board itself within the existing charter authority. The 1980 charter amendment that created the Rent Board established the framework; most operational changes have been made by the Board through regulation without additional voter action.

Berkeley just cause: §13.76.130 and the separate SFR scope

BMC §13.76.130 establishes just-cause eviction protections for covered units. The 11 enumerated just causes include non-payment of rent, breach of lease, nuisance, criminal activity, owner move-in (OMI), substantial renovation requiring temporary vacancy, and removal from the rental market under the Ellis Act. OMI is governed by specific requirements including a good-faith intent to occupy as a primary residence and anti-abuse provisions that preclude immediate re-rental at a higher rate.

Berkeley’s just-cause protections cover the same unit population as the rent cap (pre-February 1, 1995 multi-unit buildings), but the SFR exemption from the rent cap does not automatically exempt an SFR from just-cause — the SFR just-cause rules in Berkeley are governed by a separate provision and depend on whether the HHBO notice was properly served. Landlords with SFR units in Berkeley should consult §13.76.050’s SFR provisions specifically; the interplay between the SFR rent-cap exemption and the SFR just-cause applicability is one of the most frequently misunderstood aspects of Berkeley housing law.

Mountain View CSFRA Charter Article XVII — 100% × SF Bay Area CPI, 10% per-notice ceiling, Measure V (2016)

Mountain View’s Community Stabilization and Fair Rent Act (CSFRA) was enacted as City Charter Article XVII (§§1700–1716) by Measure V on November 8, 2016. The CSFRA is unusual in California rent-control law in two respects: it is a charter amendment rather than an ordinance (meaning the Mountain View City Council cannot amend or repeal it without another voter vote), and it was enacted in a city that had never previously had rent control — making Mountain View one of the first new-wave rent-control cities in Silicon Valley.

The AGA formula

CSFRA §1707(b) establishes the Annual General Adjustment:

AGA = 100% × CPI-U, San Francisco–Oakland–Hayward–Santa Rosa Metropolitan Statistical Area (Bay Area CPI), for the preceding calendar year, as published by the U.S. Bureau of Labor Statistics
Maximum AGA: 5.0% — the formula result may not exceed 5% in any rent year. For 2026: Bay Area CPI for calendar year 2025 ≈ 1.7%, so the 2026 AGA is approximately 1.7%.

Mountain View’s Rental Housing Committee publishes the annual AGA each January or early February when the BLS releases the December-to-December (or calendar-year) CPI data. The 5.0% absolute ceiling on the AGA formula has not bound in recent history, though it would have bound in 2022 if Bay Area CPI had been computed on a calendar-year basis above 5.0% (Bay Area CPI ran approximately 4.9% for calendar year 2022, just below the ceiling). The ceiling provides structural protection against the formula producing a high cap in an inflation spike year while the 100% CPI multiplier — higher than Berkeley’s 65% and Pasadena’s 75% — means that in normal CPI years, Mountain View’s AGA tracks Bay Area inflation directly.

Mountain View is in Santa Clara County and uses the SF-Oakland-Hayward-Santa Rosa MSA CPI, the same BLS series as Berkeley (though Berkeley uses a July–June window while Mountain View uses the calendar year). This means Berkeley and Mountain View are affected by the same regional inflation dynamics but apply different multipliers (65% vs. 100%) and different observation windows (July–June vs. calendar year), producing somewhat different AGA numbers in any given year even though both are anchored to the same underlying CPI series.

Mountain View banking: CSFRA §1707(c) per-notice ceiling of 10%

CSFRA §1707(c) establishes Mountain View’s banking ceiling:

A landlord may accumulate unused portions of prior-year AGAs and serve them in a future increase notice, subject to a maximum increase of 10% per notice (including both the current AGA and any accumulated banked balance).

Two features of Mountain View’s banking framework are frequently misunderstood. First, the 10% ceiling is a per-notice ceiling, not a per-year ceiling. Mountain View does not limit how much banking can be released in a single calendar year — only how much can be included in a single notice. A landlord could theoretically serve a banking-recovery notice on January 1, then serve another notice on January 2 (subject to §827(b)’s minimum notice period for the second increase taking effect), taking a second 10% notice. The practical constraint is the §827(b) minimum lead time for each notice (30 days for ≤10%, 90 days for >10%) rather than an annual ceiling on banking recovery.

Second, Utility and Ancillary Petitions (UAPs) for capital improvements under CSFRA §1710 are entirely separate from the AGA banking calculation. A landlord who receives a UAP award for a capital improvement project can impose that pass-through in addition to any AGA or banking-recovery notice; the UAP amount does not count against the 10% per-notice banking ceiling. This separates capital improvement recovery from inflation-adjustment banking in a way that does not exist in all California RSOs.

Comparing Mountain View’s 10% per-notice banking ceiling to Berkeley’s unlimited banking: in the low-inflation environment of 2026, where Mountain View’s 2026 AGA is approximately 1.7%, a landlord with three years of banked AGAs (approximately 5.1% accumulated over 2023, 2024, and 2025) can take the full balance plus the 2026 AGA (6.8% total) in a single notice well within the 10% ceiling. The ceiling only becomes binding when the accumulated balance plus the current AGA exceeds 10% — which requires either many years of deferred increases or a run of above-average AGA years that collectively stacked past 10%.

Mountain View Rental Housing Committee and administration

The CSFRA created the Mountain View Rental Housing Committee as the administering body. Unlike Berkeley’s elected Rent Board, the Rental Housing Committee is an appointed body; members are appointed by the Mountain View City Council. The Committee publishes the annual AGA, hears landlord petitions for above-AGA increases (based on just and reasonable return or operating cost increases), hears tenant petitions for rent reductions (based on decreased housing services or failure to maintain), and provides advisory opinions on coverage questions.

The appointed rather than elected structure of the Rental Housing Committee means that shifts in City Council majority can affect Committee composition and potentially interpretation of the CSFRA. However, because the CSFRA is a charter amendment rather than an ordinance, the Committee cannot change the AGA formula, the 10% per-notice banking ceiling, the February 1, 1995 cutoff, or the just-cause provisions without a voter vote — only the implementing regulations and procedural rules are within Council/Committee reach.

Mountain View just cause: CSFRA §1709

CSFRA §1709 establishes just-cause eviction protections for covered units, separate from the rent-cap provisions. The just-cause protections were a core part of Measure V and cannot be removed by the City Council without a new voter measure. Mountain View’s just-cause provisions enumerate lawful grounds for terminating a tenancy, including non-payment of rent, material breach of lease, nuisance, criminal activity, owner or immediate-family move-in (OMI), renovation requiring vacancy, and removal of the unit from the rental market. OMI evictions under §1709 require the owner (or qualified family member) to intend in good faith to occupy the unit as a primary residence and prohibit re-rental at any higher rate within a defined recovery period.

Richmond RMC Chapter 11.100 / Measure L — 100% × SF MSA CPI, elected Rent Board, November 2016

Richmond’s Fair Rent, Just Cause for Eviction, and Homeowner Protection Ordinance (FRJCE) was passed by Richmond voters as Measure L on November 8, 2016 — the same date as Mountain View’s Measure V. The coincidence of the two measures passing on the same day, from two different counties (Santa Clara vs. Contra Costa), with two similarly structured ordinances (both 100% × SF MSA CPI, both February 1, 1995 cutoff, both voter initiatives with just-cause protections), made the 2016 election a watershed moment in post-Costa-Hawkins California rent-control history. Two cities on opposite ends of the Bay Area had simultaneously enacted the most comprehensive new rent-control frameworks since the 1980 wave.

The AGA formula

Richmond Municipal Code §11.100.060 establishes the annual rent increase:

Annual increase = 100% × CPI-U, San Francisco–Oakland–Hayward MSA, for the applicable 12-month reference period as published by the U.S. Bureau of Labor Statistics, not to exceed 5.0%
For 2026: SF-Oakland-Hayward MSA CPI for the applicable reference period ≈ 1.7%, so the 2026 Richmond annual increase allowance is approximately 1.7%.

Richmond is in Contra Costa County and uses the SF-Oakland-Hayward MSA CPI, the same BLS series as Berkeley and Mountain View (though each uses a different observation window: Berkeley July–June; Mountain View calendar year; Richmond’s reference period is set by the Richmond Rent Board annually based on the published BLS data for the 12 months ending approximately March 31 or April 30 of each year, published each spring). The 100% multiplier means Richmond’s AGA tracks SF MSA inflation with no haircut — identical formula structure to Mountain View but applied to a different local market and administered by a differently constituted board.

The 5.0% absolute ceiling on Richmond’s annual increase mirrors Mountain View’s. For 2026, the ceiling is not binding because the SF MSA CPI for the reference period is well below 5.0%. In high-inflation years (for example, calendar year 2022 when Bay Area CPI ran approximately 4.9%), the 5.0% ceiling provides a structural backstop, though it is close enough to that year’s CPI that the ceiling would have been marginally binding if the reference period produced a CPI reading above 5.0%.

Richmond’s elected Rent Board

Richmond is one of the few California cities with a directly elected Rent Board. The Richmond Rent Board consists of five members elected at large by Richmond voters, serving staggered four-year terms. Like Berkeley’s elected structure, this gives Richmond’s Rent Board direct democratic accountability. The Board publishes the annual increase allowance, hears petitions for individual rent adjustments, and enforces Chapter 11.100.

Richmond’s Rent Board is the administering body for a city with a substantially different economic profile from Berkeley or Mountain View. Richmond (Contra Costa County, population approximately 115,000) has a manufacturing and industrial heritage, a large proportion of pre-1995 multi-family housing stock in the Contra Costa waterfront corridor, and median incomes below both Berkeley and Mountain View. The 100% CPI multiplier was chosen to ensure that Richmond tenants receive the full benefit of tracking inflation without the 35% haircut built into Berkeley’s formula.

Richmond banking and just cause

Richmond Chapter 11.100 permits banking with a per-notice ceiling on released balances. The specific per-notice ceiling is published annually by the Richmond Rent Board in its implementing regulations. Like Mountain View’s CSFRA model, the banking is self-executing — a landlord who has not taken the full allowable increase in prior years may accumulate unused portions and apply them in a future year’s notice, subject to the per-notice ceiling, without requiring Rent Board pre-approval. This distinguishes Richmond’s banking model from Oakland’s petition-gated model (which requires RAP pre-approval under OMC §8.22.070(B) before any above-AGA notice), even though both cities’ ordinances draw from the same SF-Oakland-Hayward MSA CPI series.

Richmond Chapter 11.100.110 establishes just-cause eviction protections, enumerated causes that parallel those in Mountain View CSFRA §1709 and Berkeley BMC §13.76.130. The full name of the Richmond ordinance — “Fair Rent, Just Cause for Eviction, and Homeowner Protection Ordinance” — reflects that just-cause and homeowner-exemption provisions were bundled into the same Measure L initiative rather than separated into independent ordinances.

Richmond in the Bay Area rent-cap landscape

Richmond’s pre-1995 multi-family buildings sit in a Contra Costa County corridor where no other city has a local RSO. El Cerrito (adjacent to the north), San Pablo, Pinole, and Hercules are all governed only by AB 1482. The cross-boundary disparity between Richmond (pre-1995 building at ≈ 1.7% under Chapter 11.100) and the adjacent El Cerrito (pre-1995 building at ≈ 8.0% under AB 1482) represents one of the largest adjacent-city rent-cap gaps in the East Bay. A tenant in a 1985-built apartment in Richmond is protected by a 1.7% cap; a tenant in an identical 1985-built apartment in El Cerrito — two miles away — faces a potential 8.0% increase. The difference reflects the presence or absence of a voter-approved local RSO, not any structural difference in the housing stock.

Pasadena PMC Chapter 8.71 / Measure H — 75% × LA MSA CPI, newest of the four (2022)

Pasadena Measure H was enacted by Pasadena voters on November 8, 2022, making it the newest of the four ordinances in this post by more than six years and one of the most recently enacted voter-initiative RSOs in California. The measure was driven by Pasadena’s experience during the 2020–2022 rent spike, when the city’s older multi-family housing stock in the Central District, Old Town, and Altadena-adjacent corridors saw year-over-year rent increases of 10–20% as pandemic-era demand redistributed from downtown Los Angeles into walkable San Gabriel Valley neighborhoods.

The AGA formula

Pasadena Municipal Code §8.71.030 establishes the annual general adjustment:

AGA = 75% × CPI-U, Los Angeles-Long Beach-Anaheim MSA (LA MSA), for the preceding calendar year, as published by the U.S. Bureau of Labor Statistics
Maximum AGA: 5.0% — the formula result may not exceed 5% in any rent year. For 2026: LA-Long Beach-Anaheim MSA CPI for calendar year 2025 ≈ 3.0%, so the 2026 AGA is approximately 2.25% (75% × 3.0%).

Pasadena is the only one of the four jurisdictions in this post that uses the LA-Long Beach-Anaheim MSA CPI rather than the SF-Oakland-Hayward MSA CPI. This is not surprising given Pasadena’s location in Los Angeles County — the LA MSA is the relevant regional inflation benchmark for Pasadena tenants and landlords, just as the SF MSA is for Berkeley, Mountain View, and Richmond. However, the choice has a material consequence for 2026 AGA comparisons: the LA MSA CPI for calendar year 2025 ran approximately 3.0%, meaningfully higher than the SF MSA’s approximately 1.7% for the same period. At Pasadena’s 75% multiplier, 75% × 3.0% = 2.25% — the highest 2026 AGA of the four ordinances in this post, despite Pasadena having the middle multiplier (65% < 75% < 100%).

This counterintuitive result — a lower multiplier producing a higher AGA than a higher multiplier — illustrates why CPI-anchor selection matters as much as the multiplier in rent-cap formula design. A formula is the product of two variables (multiplier × CPI), and the CPI variable can outweigh the multiplier difference if the underlying inflation series diverge enough across regions. For 2026, the approximately 1.3 percentage point spread between the LA MSA CPI (~3.0%) and the SF MSA CPI (~1.7%) is large enough that 75% × 3.0% (Pasadena) exceeds 100% × 1.7% (Mountain View / Richmond).

Pasadena’s 2022 enactment context: the post-COVID rent spike in the San Gabriel Valley

Between 2020 and 2022, Los Angeles County saw a structural demand shift as remote-work adoption allowed renters to leave high-density downtown neighborhoods for more spacious San Gabriel Valley housing. Pasadena, with its walkable Old Town district, California Institute of Technology campus, and Rose Bowl-adjacent neighborhoods, attracted significant demand. Pre-1995 multi-family buildings that had seen stable rents for decades began experiencing large vacancy-decontrol re-rental events — departing tenants’ below-market rents resetting to current market rates under Costa-Hawkins §1954.53, producing sudden 40–60% rent spikes for incoming tenants.

Measure H specifically addressed the AGA structure for existing tenants in pre-1995 buildings. It did not and could not limit vacancy-decontrol resetting under Costa-Hawkins, but for continuing tenants it imposed a 75% × LA-MSA-CPI cap, eliminating the unrestrained year-over-year increases that pre-Measure-H Pasadena landlords could serve (AB 1482’s ≈8.0% cap applied before Measure H passed, but Measure H’s stricter formula now governs for covered units).

For the cities immediately surrounding Pasadena — Glendale, Burbank, Arcadia, San Marino, Monrovia — no local RSO exists. All are governed only by AB 1482 at approximately 8.0% for 2026. A pre-1995 multi-family building in Pasadena is governed by Measure H at approximately 2.25%; the same vintage building in neighboring Glendale is governed by AB 1482 at approximately 8.0%. The Pasadena/Glendale cross-border disparity (approximately 5.75 percentage points) is one of the largest such gaps in Los Angeles County, comparable to the Inglewood/Hawthorne gap and the Palo Alto/East Palo Alto gap.

Pasadena banking and just cause

PMC §8.71 permits banking with a per-notice ceiling on released balances, self-executing (no Rent Board pre-approval required). The ceiling is published annually by the Pasadena Rent Board in its implementing regulations. Banking applies to accumulated AGAs that the landlord did not serve in prior years; the unused portions accumulate and can be released in a future notice, subject to the per-notice ceiling.

Pasadena’s just-cause protections, codified in PMC §8.71, provide for the standard California RSO enumeration of just causes: non-payment of rent, material lease breach, nuisance, criminal activity, OMI eviction (owner or qualified family member seeking primary residence), substantial renovation requiring vacancy, and removal from the rental market under the Ellis Act. Relocation assistance is required for certain no-fault evictions. The just-cause provisions are a voter-initiative-entrenched component of Measure H; they cannot be removed or materially weakened by the Pasadena City Council without a new ballot measure.

The Pasadena Rent Stabilization Office

The Pasadena Rent Stabilization Office, a division of the Pasadena Planning and Community Development Department, administers the RSO. A separate Rent Board hears individual petitions (landlord petitions for above-AGA increases based on operating costs; tenant petitions for rent reductions based on housing services deficiencies). Annual registration of covered units is required; an annual Rent Stabilization fee is assessed. Landlords whose units are not registered cannot lawfully serve rent-increase notices under PMC §8.71 — failure to register is both a barrier to rent increases and an independent ordinance violation subject to penalties.

Banking model comparison across the four: unlimited vs. per-notice ceiling

All four ordinances permit banking — but Berkeley’s model is structurally different from the other three in ways that matter for landlords with large accumulated balances.

The critical structural distinction: Berkeley has no per-notice ceiling but has a four-condition gate; Mountain View, Richmond, and Pasadena have a per-notice ceiling but no gate conditions beyond the ceiling itself. This produces different failure modes for landlords:

• Berkeley landlord blocked by AGA-denial gate (e.g., Rent Board compliance issue): cannot collect any banked balance until all four conditions are cleared, even though the balance continues accumulating. Once cleared, the full accumulated balance (however large) becomes collectible in one notice. The gate is transient — fixing the compliance issue clears it.
• Mountain View / Richmond / Pasadena landlord with large balance exceeding the per-notice ceiling: must split the recovery across two or more notices, each waiting for the §827(b) minimum notice period to run. There is no gate — the landlord is never blocked from serving a notice, only constrained on how much each notice can contain.

Three-year catch-up scenario: $2,000 base rent, increases skipped for 2023, 2024, 2025

To illustrate the banking model differences concretely, consider a $2,000/month unit in each city where the landlord served no rent-increase notices for three full years (2023, 2024, and 2025) and now wishes to serve a notice effective 2026, collecting all three years’ accumulated balance plus the 2026 AGA in a single notice.

Using approximate AGAs for each city over the three skipped years (these are rounded illustrative figures consistent with published Rent Board data; landlords should confirm exact published AGAs with the controlling board before serving a notice):

In this three-year scenario with a low-CPI accumulation period (2023–2025), all four produce accumulated totals well within any reasonable per-notice ceiling. The differences are driven by the underlying AGA formula: Pasadena’s higher LA-MSA AGA (approximately 2.25%/year) produces a larger accumulated balance than the SF-MSA-anchored jurisdictions (approximately 1.7%/year for Mountain View and Richmond) or Berkeley (approximately 1.0–1.7%/year depending on the rent year CPI).

The scenario where per-notice ceilings actually constrain Mountain View and Richmond recovery is the high-CPI accumulation period: three years of approximately 4.0–5.0% AGAs (as occurred in many California jurisdictions in 2022–2024) would produce accumulated balances of 12–15%, which when added to the current AGA exceed the 10% per-notice ceiling. In that scenario, Mountain View landlords need two notices to recover the full balance (10.0% in notice 1, remainder in notice 2) while Berkeley landlords — if the AGA-denial gate is clear — can take the full 12–15% in a single notice.

Compared to the jurisdictions in the permanent-forfeit band (AB 1482, LA RSO, Santa Monica, Hayward, Culver City, Beverly Hills), all four of these overlays are substantially more favorable for landlords who defer rent increases: skipped years are recoverable, not permanently lost. The difference between the forfeit band and the per-notice-ceiling band is permanent vs. recoverable; the difference between Berkeley’s unlimited model and the per-notice-ceiling model is a matter of how many notices are needed to recover a large balance.

Voter-initiative entrenchment and the preemption landscape

All four ordinances were enacted directly by voters rather than by city councils. Berkeley’s 1980 charter amendment, Mountain View Measure V (2016), Richmond Measure L (2016), and Pasadena Measure H (2022) are each voter initiatives that can only be repealed or substantively amended by another vote of the electorate. This creates structural durability that council-enacted ordinances like Oakland’s RAP (OMC Chapter 8.22, council-enacted and amended) or Hayward’s RRSO (HMC Chapter 12, council-enacted) do not have.

What voter-initiative entrenchment means in practice

A hostile city council majority cannot repeal a voter-initiative RSO by a council vote. To repeal or substantively weaken Berkeley BMC §13.76, Mountain View CSFRA, Richmond Chapter 11.100, or Pasadena PMC §8.71, landlord interests would need to place a repeal measure on the ballot and win a majority of voters. In Berkeley’s 40-plus-year history, the Rent Board has faced political opposition but the charter amendment has survived every challenge. In Mountain View, Richmond, and Pasadena, the ordinances are newer and have not yet faced a ballot repeal campaign.

Voter-initiative entrenchment also means that incremental council amendments are constrained. A council in Mountain View cannot, by ordinance, change the CSFRA’s 10% per-notice banking ceiling, modify the February 1, 1995 first-CoC cutoff, or add categories of units to the coverage scope (though they can enact complementary non-charter ordinances for non-CSFRA issues). The same structural limitation applies in Richmond and Pasadena.

The Costa-Hawkins preemption shield — and its limits

The February 1, 1995 first-CoC alignment gives all four ordinances a specific immunity to Costa-Hawkins preemption challenges on coverage scope: because they do not attempt to control post-1995 rents, there is no ground to challenge them under §1954.52(a)(1). This is the narrow but important sense in which these four ordinances are “Costa-Hawkins-hardened.”

But Costa-Hawkins is not the only preemption risk for California RSOs. The following categories of potential preemption remain relevant for all four:

• Statewide preemption legislation: The California Legislature could enact a law preempting all local rent control — not just post-1995 units but all units. Such bills have been introduced in Sacramento multiple times (see, e.g., SB 50 and AB 2011 discussions) but have not passed as of 2026. If a comprehensive statewide preemption bill were enacted, it would override all four ordinances, voter initiative or not, because state law preempts conflicting local ordinances in California (including charter city ordinances for non-municipal affairs). Rent control is classified as a matter of statewide concern in California, meaning state law can preempt local ordinances in this area.
• AB 1482’s relationship to local RSOs: AB 1482 (Cal. Civ. Code §1947.12, effective January 1, 2020) is a statewide backstop, not a preemption of local RSOs. §1947.12(h)(2) explicitly preserves local RSOs that are more protective than the statewide law. All four ordinances in this post are more protective than AB 1482 for their covered units (lower caps, banking provisions, just-cause protections), so AB 1482 applies only to units that are not covered by the local RSO (post-1995 buildings, SFRs/condos without HHBO notice, etc.).
• Charter city home-rule doctrine: Berkeley and Mountain View are charter cities; Richmond and Pasadena are general-law cities. Charter cities have broader home-rule authority under Cal. Const. Art. XI §5 for “municipal affairs” but rent control has been classified as a statewide concern by California courts in multiple decisions — meaning the charter city designation does not provide immunity from statewide preemption laws.

The two Costa-Hawkins ballot defeats (Proposition 10 in 2018 at 61% No; Proposition 21 in 2020 at 60% No) suggest that as of 2026, the political coalition for statewide preemption reversal has not been assembled. Conversely, the passage of new RSOs in Mountain View, Richmond, and Pasadena during the same period suggests that local rent control has political durability as a ballot initiative strategy even as statewide efforts to expand it have failed.

The preemption asymmetry: Berkeley vs. the 2016–2022 ordinances

Berkeley’s 1980 voter enactment gives it the longest track record of legal survival in this group: 46 years of litigation, legislative efforts, and political challenges, all of which the ordinance has survived. Its age also means it was tested under the original pre-Costa-Hawkins legal environment and successfully amended to comply with Costa-Hawkins, demonstrating the amendment mechanism works. The Berkeley Rent Board has significant institutional experience in defending the ordinance.

Mountain View, Richmond, and Pasadena have shorter track records, but their clean post-Costa-Hawkins draftsmanship eliminates the compliance amendment risk that Berkeley faced in the late 1990s. All three were written by attorneys with full knowledge of the Costa-Hawkins framework and the legal challenges that pre-Costa-Hawkins ordinances had faced. Pasadena’s 2022 Measure H in particular reflects 27 years of California rent-control jurisprudence in its drafting, making it one of the most legally precise California RSO texts in the current catalogue.

The CPI divergence question: why the same “Bay Area CPI” produces different results for each city

Three of the four jurisdictions in this post use some version of the SF-Oakland-Hayward MSA CPI: Berkeley (65% × July–June CPI), Mountain View (100% × annual calendar-year CPI), and Richmond (100% × applicable 12-month CPI). Despite all three using the same underlying BLS data series, they can produce different AGA numbers in any given year because:

1. Different multipliers: Berkeley’s 65% multiplier reduces the CPI impact by 35% relative to Mountain View’s and Richmond’s 100%. At the same 1.7% CPI reading, Berkeley produces a 1.1% AGA while Mountain View produces a 1.7% AGA. This multiplier gap is the most consistent source of divergence between Berkeley and the other two.
2. Different observation windows: Berkeley uses July 1 to June 30 of the prior year; Mountain View uses the full prior calendar year (approximately January to December); Richmond uses a 12-month period ending approximately March or April. In any year where CPI moved significantly in the second half of the calendar year, these different windows will capture different slices of the CPI movement and produce different base numbers for the multiplier to be applied to.
3. Different absolute ceilings: Berkeley’s AGA formula is capped at 7.0%; Mountain View’s and Richmond’s are capped at 5.0%. In a high-inflation year where the underlying CPI produced a formula result above 5.0% for Mountain View, Mountain View’s AGA would be capped at 5.0% while Berkeley’s (at 65% of the same CPI) might produce only 3.25% — well below its own 7.0% ceiling.

The practical consequence: a Bay Area landlord who owns pre-1995 units in both Berkeley and Mountain View (or both Berkeley and Richmond) cannot use one city’s published AGA as a proxy for the other. The controlling figure in each city is the AGA published by that city’s Rent Board or Committee for the specific rent year in question. The RentCeiling calculator tracks all three separately.

Pasadena’s use of the LA-Long Beach-Anaheim MSA CPI introduces a fourth data series entirely. Pasadena landlords who also own Bay Area units face the additional complexity that the two CPI anchors are driven by different regional economies — the Bay Area CPI is dominated by the tech sector employment cycle; the LA MSA CPI is driven by a more diversified economy including entertainment, manufacturing, and logistics. In 2025, the LA MSA CPI ran approximately 1.3 percentage points higher than the SF MSA CPI, producing a materially different AGA landscape across the two metro areas.

Frequently asked questions

Why do Berkeley, Mountain View, Pasadena, and Richmond all use February 1, 1995 as their rent-control cutoff?

February 1, 1995 is the date written into the Costa-Hawkins Rental Housing Act at Cal. Civ. Code §1954.52(a)(1). Costa-Hawkins prohibits local rent control on any unit whose first certificate of occupancy was issued on or after that date. By drawing their coverage boundary at February 1, 1995, each of the four ordinances ensures it governs only units that state law permits it to govern. Berkeley arrived at this date by amending its 1980 ordinance after Costa-Hawkins was enacted. Mountain View, Richmond, and Pasadena arrived at the date by designing their post-1995 ordinances to comply with it from the start. The result — all four sharing the same cutoff despite being enacted in 1980, 2016, 2016, and 2022 — reflects the universal binding effect of §1954.52(a)(1) on every California rent-stabilization ordinance.

My building’s first CoC is February 2, 1995. Am I covered by any of these four ordinances?

No. Cal. Civ. Code §1954.52(a)(1) exempts units with first CoC “on or after February 1, 1995.” February 2, 1995 is one day past the cutoff. The exemption applies to your unit in all four cities. The applicable regime is AB 1482 (Cal. Civ. Code §1947.12) at approximately 8.0% for 2026 in the Bay Area MSAs and LA MSA, provided the unit is not separately AB 1482-exempt under the 15-year rolling exemption at §1947.12(d)(4)(A) (a 1995-built building will graduate out of the 15-year rolling exemption in 2010 — it is already subject to AB 1482), the SFR/condo HHBO-notice exemption, or another specific carve-out. A building with first CoC on February 1, 1995 exactly is one day inside the cutoff: §1954.52(a)(1) exempts units with first CoC “on or after” the date, meaning February 1 itself is the boundary. Under standard statutory construction, “on or after February 1, 1995” means February 1 is the first exempted day, so a first CoC dated February 1, 1995 is Costa-Hawkins-exempt. The covered range is first CoC through January 31, 1995.

How does Berkeley’s unlimited banking compare to Mountain View’s 10% per-notice ceiling for a landlord with a large accumulated balance?

For small balances (accumulated banked percentage plus current AGA under 10%), both models produce the same practical result: the full balance is collectible in one §827(b) notice. The models diverge when the accumulated balance plus current AGA exceeds 10%. A Berkeley landlord whose balance is 12% accumulated (four years at varying AGAs) plus a 1.0% current AGA (13% total) can serve a single notice for the full 13% if all four AGA-denial gate conditions at §13.76.110(B)(2) are satisfied (registered, Rent Board compliance, no habitability violations, deposit interest current). A Mountain View landlord in the identical situation can take only 10% in the first notice under CSFRA §1707(c), carry the remaining 3% forward, wait for the §827(b) minimum lead time for a second notice, then serve the second notice for the remaining 3% plus the next AGA. The Berkeley model is faster for large balances but conditioned on the four-factor gate; the Mountain View model is unconditional on gate factors but requires splitting large balances across multiple notices. For most landlords in the current low-AGA environment, the practical difference is small: three years of approximately 1.7% AGAs (5.1% accumulated) is well within Mountain View’s 10% ceiling.

Can I apply the same rent-increase notice template across Berkeley, Mountain View, Richmond, and Pasadena?

No. Each city requires jurisdiction-specific notice content beyond California Civil Code §827(b)’s baseline (30-day lead for ≤10% increases; 90-day lead for >10%). Berkeley notices must cite the current Rent Board AGA by regulation number, state whether the increase is based on the current AGA alone or includes a banked balance, and comply with the Rent Board’s annual required-notice-content checklist; the unit must be currently registered with the Berkeley Rent Board before any notice can be served. Mountain View notices must cite CSFRA §1707 and the Rental Housing Committee’s published AGA for the current rent year; the unit must be registered with the Rental Housing Committee. Richmond notices must cite Chapter 11.100 and the Richmond Rent Board’s published annual increase allowance; unit registration with the Richmond Rent Board is required. Pasadena notices must cite PMC §8.71 and the Pasadena Rent Stabilization Office’s published AGA; Pasadena unit registration is required. A generic California rent-increase notice that satisfies §827(b) but lacks the jurisdiction-specific citations and disclosures is defective under each local ordinance and may be voidable by the tenant in a subsequent unlawful-detainer action or Rent Board proceeding. The RentCeiling PDF generator produces jurisdiction-specific notices that include the required citations for each city.

Why does Pasadena produce a higher 2026 AGA than Mountain View and Richmond, even though Pasadena’s CPI multiplier (75%) is lower than theirs (100%)?

The AGA is the product of two variables: the multiplier and the underlying CPI. Pasadena uses the LA-Long Beach-Anaheim MSA CPI; Mountain View and Richmond use the SF-Oakland-Hayward MSA CPI. For calendar year 2025, the LA MSA CPI ran approximately 3.0% while the SF MSA CPI ran approximately 1.7% — a gap of approximately 1.3 percentage points. Applying the multipliers: 75% × 3.0% (Pasadena) = 2.25%; 100% × 1.7% (Mountain View / Richmond) = 1.7%. Pasadena’s lower multiplier is more than offset by the higher LA MSA CPI, producing a higher AGA. This illustrates a general principle in multi-jurisdiction rent-cap analysis: comparing multipliers across cities is meaningful only when the underlying CPI anchors are the same. When the anchors differ — LA MSA vs. SF MSA — the multiplier comparison alone is misleading. A city with a 100% multiplier on a 1.5% CPI will produce a lower AGA than a city with a 60% multiplier on a 4.0% CPI.

Are Berkeley, Mountain View, Richmond, and Pasadena affected by AB 1482?

AB 1482 (Cal. Civ. Code §1947.12) applies in all four cities, but only to units that are not covered by the local RSO. Cal. Civ. Code §1947.12(h)(2) explicitly provides that local rent-stabilization ordinances that are more protective than AB 1482 remain in force and are not preempted by the statewide law. For pre-February 1, 1995 multi-family units in Berkeley, Mountain View, Richmond, and Pasadena that are not otherwise exempt (SFR, condo with HHBO notice, subsidized housing, etc.), the local RSO governs — not AB 1482. The local RSO’s cap (approximately 1.0–2.25%) is more protective than AB 1482’s cap (approximately 8.0%) and therefore controls. AB 1482 applies to three categories in these four cities: (1) Post-February 1, 1995 units (Costa-Hawkins-exempt from local RSO, covered by AB 1482 unless also AB-1482-exempt under the 15-year rolling exemption); (2) SFRs and condos with HHBO notice (exempt from local RSO under Costa-Hawkins, covered by AB 1482 unless separately exempt); (3) Any other unit type that falls in a gap between the local RSO’s coverage and AB 1482’s coverage.

What are the penalties for overcharging rent in Berkeley, Mountain View, Richmond, or Pasadena?

All four jurisdictions provide similar penalty structures for overcharges, drawing from the California standard of rent rollback, refund, treble damages for willful violations, attorney fees, and a three-year limitation period. Berkeley BMC §13.76.150: tenants may seek rent reduction to lawful rate plus refund of the overcharge with 10% annual interest under Cal. Civ. Code §3289(b); treble damages under §13.76.150(C) for willful violations; attorney fees under §13.79. Mountain View CSFRA §1714: the Rental Housing Committee or Superior Court may order rent rollback, refund with interest, treble damages for willful violations, and attorney fees to the prevailing tenant. Richmond Chapter 11.100.120: the Richmond Rent Board or Superior Court may order rent reduction, refund with interest, treble damages for willful violations, and attorney fees. Pasadena PMC §8.71 enforcement provisions: the Rent Board or Superior Court may order the five-prong remedy (rent rollback, refund with interest, civil penalties, treble damages for willful violations, attorney fees). In all four cities, a tenant may also raise an unlawful overcharge as an affirmative defense to an unlawful-detainer action for non-payment under Cal. Code Civ. Proc. §1161, potentially voiding an eviction based on non-payment of a rent that was itself unlawfully above the applicable cap. The three-year statute of limitations (Cal. Code Civ. Proc. §338 for written instruments) applies to overcharge recovery claims in all four jurisdictions, meaning a landlord who has overcharged for more than three years faces liability only for the most recent three years of overcharges (though the rent reduction itself can be ordered prospectively without a lookback limitation).

Putting it together: the most legally defensible California rent-control cluster

Berkeley, Mountain View, Richmond, and Pasadena form a distinctive cluster in California rent-control law: all four are voter initiatives, all four use February 1, 1995 as their first-CoC cutoff, all four comply with every provision of the Costa-Hawkins Rental Housing Act, and none of the four attempts to control any rent that state law prohibits local ordinances from controlling.

For landlords, the practical implications are:

• Know which side of February 1, 1995 your building is on. The first CoC date determines whether the local RSO or AB 1482 governs. The local RSO at ~1.0–2.25% is substantially more restrictive than AB 1482 at ~8.0%.
• Banking is available in all four — do not forfeit it. Unlike the permanent-forfeit jurisdictions (AB 1482, LA RSO, Santa Monica, Hayward), unused annual increases in these four jurisdictions accumulate. Deferring a notice is a recoverable decision, not a permanent loss — but only as long as the tenancy continues. Banking balances reset to zero when a tenant vacates.
• Notice content must be jurisdiction-specific. A single generic notice template does not satisfy the ordinance-citation requirements of Berkeley, Mountain View, Richmond, or Pasadena. Defective notices are voidable.
• All four require registration. Serving a rent-increase notice while the unit is unregistered is a violation independent of whether the increase amount is lawful. Confirm current registration status with the controlling Rent Board before serving any notice.

The RentCeiling calculator covers all four cities in this cluster, and the notice PDF generator produces jurisdiction-specific notices that include the required ordinance citations, AGA calculations, and tenant-rights disclosures for each.
