Fremont rent control 2026 No local RSO. AB 1482 applies: 2026 cap ≈ 8% (5% + ~3% SF-Oakland-Hayward MSA CPI [April-to-April], below 10% ceiling).

Fremont's 2026 cap: AB 1482 with SF-Oakland-Hayward MSA CPI

Under California Civil Code §1947.12(a)(1), the maximum annual rent increase for a covered Fremont residential rental unit is the lesser of:

1. 5.0% plus the percentage change in the Consumer Price Index for All Urban Consumers (CPI-U) for the San Francisco-Oakland-Hayward, CA Metropolitan Statistical Area for the 12-month period ending on April 1 of the year prior to the increase (or the most recently published 12-month period ending before the effective date of the increase); OR
2. 10.0% absolute ceiling.

Fremont is in Alameda County, part of the San Francisco-Oakland-Hayward, CA MSA (sometimes also called the Oakland-Fremont-Berkeley Metro Division). For AB 1482 purposes, the applicable CPI is the SF-Oakland-Hayward MSA CPI (All Urban Consumers), April-to-April observation window. For 2026, the April 2024–April 2025 change in this CPI is running approximately 3.0%. Calculation: 5% + 3% = 8%, below the 10% ceiling. Fremont’s 2026 AB 1482 rent-cap is approximately 8%.

The Alameda County overlay comparison for 2026:

• Fremont (AB 1482 only) — ~8% for 2026 (5% + ~3% SF MSA CPI, April-to-April). This page.
• Newark (AB 1482 only) — ~8% for 2026. No local RSO. Same SF MSA CPI. Adjacent to Fremont.
• Union City (AB 1482 only) — ~8% for 2026. No local RSO. Same SF MSA CPI. Borders Hayward.
• Oakland RAP (OMC Chapter 8.22) — ~1.7% for 2026 (100% × SF CPI, March-to-March, capped at 3.0%). December 31, 1982 first-CoC cutoff. Petition-gated banking.
• Berkeley BMC Chapter 13.76 — ~1.0% for 2026 (65% × SF CPI, July-to-June, capped at 7%). February 1, 1995 first-CoC (Costa-Hawkins-anchored). Unlimited banking.
• City of Alameda RROSL (AMC Chapter 6, Ordinance No. 3148) — ~1.2% for 2026 (~70% × SF CPI, March-to-March). February 1, 1995 first-CoC. Per-notice-ceiling banking.
• Hayward RRSO (HMC Chapter 12) — 5.0% flat for 2026. No CPI multiplier. July 1, 1979 first-CoC. No banking (forfeit model).

The key structural difference: each Alameda County local overlay uses the SF-Oakland-Hayward MSA CPI but measures it over a different window (March-March for Oakland and Alameda; July-June for Berkeley) and applies a different multiplier (65% Berkeley, ~70% Alameda, 100% Oakland), producing 2026 caps of 1.0–1.7%. AB 1482 adds a 5% additive to the same CPI series but uses the April-to-April window, producing a fundamentally different result of ~8%. Fremont’s landlords are subject to the latter framework exclusively; Fremont tenants in identical pre-1995 buildings face a cap more than 5× higher than Oakland tenants one city border away.

The April-to-April window: why Fremont's AB 1482 and Oakland's RAP diverge

This is one of the most counterintuitive features of the California rent-cap landscape: Fremont and Oakland draw from the same CPI-U data series (SF-Oakland-Hayward MSA, published by the Bureau of Labor Statistics), yet arrive at radically different 2026 caps. The explanation has two parts:

Part 1: Different observation windows. Oakland’s RAP (OMC §8.22.070(A)) uses the March-to-March window: the percentage change in the SF CPI from March of the prior year to March of the calendar year before the effective date. For 2026 Oakland RAP calculations, this is March 2024–March 2025, which yielded approximately 1.7%. AB 1482 (§1947.12(a)(1)) uses the April-to-April window: the 12-month change ending April 1 of the prior year. For 2026 AB 1482 calculations, this is April 2024–April 2025, which ran approximately 3%. Monthly CPI data can vary; the choice of endpoint months can shift the year-over-year reading by a percentage point or more.

Part 2: Formula structure. Even if the observation windows were identical, the formula structure would produce a large gap. Oakland RAP applies 100% of CPI (capped at 3.0%), so ~1.7% CPI → ~1.7% AGA (capped at 3%). AB 1482 adds 5% to CPI (capped at 10%), so ~3% CPI → ~8% AB 1482 cap. The 5% additive in AB 1482 was a legislative compromise designed to allow meaningful rent growth while preventing extreme rent-gouging — but it results in a far higher cap than any CPI-fraction local overlay in the same MSA.

For a Fremont landlord: use the SF-Oakland-Hayward MSA CPI for the 12-month period ending April 1 of the prior year (or the most recently published period before the effective date of the increase). Do not use Oakland’s March-to-March figure or Berkeley’s July-to-June figure; those are specific to those cities’ local ordinances and are NOT the correct AB 1482 figure for Fremont.

Why Fremont has no local rent control

The City of Fremont (population ~235,000), formed in 1956 from the consolidation of five smaller communities (Centerville, Niles, Irvington, Warm Springs, and Mission San Jose), is California’s fourth-largest city by population. Despite its size and its location in Alameda County — which has the highest concentration of local rent-control ordinances in California — Fremont has not enacted a local RSO. Structural factors:

• Suburban housing stock composition: Fremont’s development pattern since the 1956 incorporation has been relatively dispersed, with a significant proportion of single-family homes and low-density multi-family buildings spread across distinct former-community neighborhoods (Centerville, Niles, Mission San Jose, Irvington). The density of rent-control-eligible pre-1995 multi-unit buildings is lower relative to Oakland or Berkeley, reducing the political coalition that would benefit from a local RSO.
• Costa-Hawkins constraint: Any local Fremont RSO would be limited by Costa-Hawkins (§1954.52(a)(1)) to buildings with first CoC before February 1, 1995 (or an earlier cutoff). A significant portion of Fremont’s apartment stock — particularly around the BART-adjacent Warm Springs/South Fremont development corridor — was built after 1995 and could not be covered by a local RSO.
• Industrial and tech-employer base: Fremont’s employment base (Tesla’s Fremont Factory, Lam Research headquarters, Western Digital, and numerous semiconductor and EV supply-chain employers) skews toward higher-income white-collar and skilled-trade workers less reliant on rent-stabilized housing than the renter populations in Oakland or Berkeley that drove local RSO campaigns.
• Post-AB-1482 landscape: AB 1482’s passage in 2019 provided a statewide baseline that reduced political urgency for a Fremont-specific RSO, as it did for Newark, Union City, and other Alameda County cities without pre-existing local overlays.

The practical consequence: a tenant in a 1985 garden-apartment complex in Fremont’s Niles neighborhood faces an AB 1482 cap of ~8% for 2026; a tenant in an identical building in neighboring Oakland’s Fruitvale neighborhood faces an Oakland RAP cap of ~1.7%. Both buildings are subject to the same SF-Oakland-Hayward MSA economic conditions; the 6+ percentage point difference reflects solely the presence or absence of a local rent-control ordinance.

Which Fremont units does AB 1482 cover?

AB 1482 covers Fremont residential rental units unless excluded under Cal. Civ. Code §1947.12(d):

• Newly constructed units (15-year rolling exemption). Buildings with certificates of occupancy issued within the last 15 years are exempt. For 2026, buildings completed in or after approximately 2011 are exempt, including developments near Warm Springs BART and the Fremont Station Transit Village.
• Single-family homes and condominiums with a valid HHBO notice. A detached SFR or condominium where the landlord provided the AB 1482 Homeowner Exemption Notice (§1947.12(d)(5)(B)) at or before the commencement of tenancy (or before January 1, 2020 for pre-existing tenancies) is exempt. Failure to timely serve the HHBO notice means the unit is NOT exempt.
• Owner-occupied duplexes where the landlord occupies one unit as primary residence.
• Government-subsidized affordable housing (LIHTC, Section 8 PBV, BMR, RAD) with a recorded affordability agreement. Fremont administers a Below Market Rate (BMR) rental program through its Housing Division; BMR units are exempt from the AB 1482 rent-cap framework.
• Dormitories operated by accredited educational institutions (e.g., units adjacent to Ohlone College Fremont campus).
• Hotels, motels, and short-term accommodations under 30 days.

Fremont’s older neighborhoods (Centerville, Niles, Irvington) contain pre-1980 multi-unit residential buildings that are fully covered by AB 1482’s ~8% cap. Landlords in those neighborhoods with pre-2011 buildings and long-term tenants are subject to the full AB 1482 framework.

Notice requirements for Fremont rent increases

California Civil Code §827(b) governs form and timing for all Fremont residential rent-increase notices:

• 30-day rule under §827(b)(2)(A) — increases of less than 10% take effect 30 calendar days after service. Fremont’s ~8% AB 1482 cap is under the 10% threshold, so all standard Fremont rent-increase notices qualify for the 30-day rule.
• 90-day rule under §827(b)(3) — increases of 10% or more require 90 calendar days. Unreachable under AB 1482’s 10% ceiling.
• §1013 mailing-add — 5 additional days when notice is served by U.S. Mail. Effective period: 35 days for standard Fremont notices.
• AB 1482 §1947.13 tenant-rights disclosure — required at commencement of tenancy and when serving any rent increase notice for covered units.
• No Fremont city-level notice requirements — unlike Oakland (RAP registration + notice citation), Berkeley (Rent Board registration + notice citation), and City of Alameda (RROSL registration + notice citation), Fremont has no municipal registration program and no city-level notice citation requirement. Only the statewide §827(b) and §1947.13 rules apply.
• 12-month frequency rule — AB 1482 limits landlords to two rent increases per 12-month period, with the combined amount not exceeding the AB 1482 cap.

Just-cause eviction in Fremont

AB 1482 §1946.2 imposes just-cause eviction requirements on covered Fremont residential rental units after 12 months of continuous occupancy. The City of Fremont has no local just-cause eviction ordinance; §1946.2 is the only just-cause protection for Fremont tenants.

The structural contrast with Oakland is significant. Oakland OMC §8.22.300, as expanded by Measure JJ (November 2018), provides universal just-cause eviction protections covering all Oakland residential rentals regardless of RAP rent-cap coverage — including post-1982 buildings, SFRs, and newly constructed units. Fremont has no equivalent universal provision; Fremont tenants in units exempt from the AB 1482 rent-cap (newly constructed, SFRs with HHBO) may have limited or no just-cause eviction protection under §1946.2 if the tenancy has not crossed the 12-month threshold or if the unit falls outside §1946.2’s scope.

The 11 AB 1482 just causes under §1946.2:

1. Non-payment of rent
2. Material breach of a lease term not cured after written notice
3. Maintaining a nuisance or causing substantial damage
4. Refusal to permit lawful access (Cal. Civ. Code §1954)
5. Unauthorized sub-letting in violation of the lease
6. Refusal to renew a written lease at expiration on substantially similar terms
7. Criminal activity on the premises
8. Owner or qualified family member intends to occupy as primary residence (90-day notice; one month relocation assistance for 12+ months’ tenancy)
9. Withdrawal of the unit from the rental market (relocation assistance required)
10. Substantial rehabilitation under permit requiring temporary vacancy
11. Demolition with permit

Relocation assistance equal to one month’s rent applies to owner-move-in and withdrawal-from-market evictions for tenancies of 12 months or more. Ellis Act withdrawals follow Cal. Gov. Code §§7060–7060.7 and trigger §1954.535 re-rental restrictions.

Penalty for exceeding AB 1482 in Fremont

A rent collected above the lawful AB 1482 cap in Fremont is unlawful under Cal. Civ. Code §1947.12. Because Fremont has no local RSO and no local hearing officer, tenants must pursue remedies in Alameda County Superior Court rather than through an administrative petition process. The contrast with Oakland is direct: an Oakland RAP overcharge is handled administratively through Oakland’s Rent Adjustment Program (RAP petition, Form RAP-100 series); a Fremont AB 1482 overcharge requires a civil action in Alameda County Superior Court.

AB 1482 remedies under §1947.12(h):

1. Reduction of rent to the lawful AB 1482 rate.
2. Refund of the unlawfully-collected amount with statutory interest at 10% per year under Cal. Civ. Code §3289(b).
3. Treble damages where willful — up to three times the unlawfully-collected rent, not less than $250 per violation (§1947.12(h)(3)).
4. Attorney fees to prevailing tenants under §1947.12(i).

The three-year limitation under Cal. Code Civ. Proc. §338 applies. Tenants may raise the AB 1482 overcharge as an affirmative defense to an unlawful-detainer action for non-payment under Cal. Code Civ. Proc. §1161.

Fremont vs. Oakland, Berkeley, Hayward: the Alameda County cross-boundary gap

Fremont is the largest city in Alameda County without a local RSO. Its four major neighbor cities within Alameda County all have local overlays; the contrast table for 2026:

• Fremont (AB 1482) — ~8% cap for 2026. No local RSO. No local petition process. No annual registration. SF MSA CPI (April-April, ~3%) + 5% additive. 15-year rolling exemption (pre-2011 for 2026).
• Oakland RAP (OMC Chapter 8.22) — ~1.7% cap for 2026 (100% × SF MSA CPI, March-March, capped at 3.0%). December 31, 1982 first-CoC. Petition-gated banking (RAP Form RAP-100 pre-approval, 60–90 day review). ~$30–$40/year RAP Service Fee per unit. Universal just-cause (OMC §8.22.300, expanded Measure JJ 2018).
• Berkeley BMC Chapter 13.76 — ~1.0% cap for 2026 (65% × SF MSA CPI, July-June, capped at 7%; 2026 is the lowest CA overlay cap in the catalogue). February 1, 1995 first-CoC. Unlimited banking (no per-notice or per-year ceiling; subject to AGA-denial gate §13.76.110(B)(2)).
• City of Alameda RROSL (AMC Chapter 6, Ordinance No. 3148) — ~1.2% cap for 2026 (~70% × SF MSA CPI, March-March). February 1, 1995 first-CoC. Per-notice-ceiling banking.
• Hayward RRSO (HMC Chapter 12) — 5.0% flat cap for 2026. No CPI multiplier. July 1, 1979 first-CoC (earliest in Alameda County). No banking (permanent forfeit). Just-cause added 2019.

A landlord managing a cross-city portfolio in Alameda County faces five distinct regulatory frameworks within a single county. Fremont units require only AB 1482 §1947.12 compliance (no registration, no local program, no annual fee). Oakland units require RAP registration, annual AGA calculation (100% × SF CPI capped at 3%), petition-gated banking compliance, and just-cause compliance for all units under OMC §8.22.300. Berkeley units require Rent Board registration, annual AGA tracking (65% × SF CPI capped at 7%), unlimited-banking compliance subject to the AGA-denial gate, and annual security-deposit interest payments. The three-city compliance burden for a portfolio spanning Fremont + Oakland + Berkeley would require three separate administrative registrations, three separate cap publication calendars, three separate banking frameworks, and three separate notice templates.

How RentCeiling handles Fremont AB 1482 compliance

The free California calculator routes Fremont units to the AB 1482 lesser-of formula using the SF-Oakland-Hayward MSA CPI (April-to-April observation window), with the 15-year rolling exemption check (pre-2011 for 2026?), the SFR/condo HHBO-notice status check, the §1946.2 just-cause trigger check, and the 12-month increase-frequency rule. The California notice generator emits a §827(b)-compliant Fremont rent-increase notice with the AB 1482 §1947.13 disclosure attached and the §1013 mailing-add applied. The Oakland RAP page walks the neighboring overlay for Oakland units. The Berkeley BMC page walks the Berkeley overlay. The City of Alameda RROSL page covers the Alameda island-city overlay. The Hayward RRSO page covers the flat-rate Hayward overlay. The California overview page places Fremont in the full multi-jurisdiction catalogue. Open rule-set at /rules/california.json.
