Capital improvement pass-through rent increases in rent-controlled cities 2026: NYC MCI, San Francisco §37.7, Los Angeles RSO IRA, Oakland, DC, Berkeley, and Santa Monica — the complete landlord petition guide

Why rent-controlled cities allow above-cap increases for capital improvements

Rent control ordinances set annual caps on rent increases — CPI-indexed, fixed percentages, or hybrid formulas. Without some safety valve, those caps create a fundamental economic problem: if a landlord cannot raise rents enough to pay for major capital investments (a new roof, a seismic retrofit, a boiler replacement), aging housing stock deteriorates. Rent boards in every major city recognize this. The solution, adopted uniformly across NYC, San Francisco, Los Angeles, Oakland, Berkeley, Santa Monica, and Washington DC, is a separate petition track for capital improvements: a landlord who has made a qualifying permanent improvement to the building can petition the relevant administrative body for an above-cap temporary surcharge, amortized over the useful life of the improvement.

The critical features of these systems:

• Petition-based: The above-cap increase is never automatic. The landlord must file a petition, submit documentation, and in most jurisdictions serve notice on tenants who have the right to object.
• Temporary: The surcharge expires at the end of the improvement’s useful life or amortization period. It is not a permanent addition to the base rent (with the historical exception of pre-2019 NYC MCIs — a feature eliminated by the HSTPA).
• Additive to the annual cap: The capital improvement surcharge is above and in addition to the standard annual guideline increase. A landlord can collect both in the same year.
• Partial cost recovery: No jurisdiction requires tenants to fund the entire improvement. NYC allows full amortized cost recovery subject to a 2%/3% annual cap per unit. San Francisco requires the landlord to absorb 50% of the cost. LA RSO sets the pass-through based on LAHD’s determination of allowable costs. Oakland and Berkeley have their own formulas.
• Administrative oversight: Rent boards, DHCR hearing officers, LAHD hearing officers, and the Rental Housing Commission review petitions, determine qualifying costs, and set amortization periods. Tenant objections can trigger a full hearing.

Before filing any petition, two threshold questions must be answered: (1) Does the work qualify as a “capital improvement” rather than maintenance or repair? (2) Is the documentation (building permits, contractor invoices, proof of payment) complete? Answering both correctly before filing determines whether the petition succeeds or fails.

What qualifies as a capital improvement — and what does not

The distinction between a qualifying capital improvement and ordinary maintenance is the central fact question in every rent board petition. The line varies slightly by jurisdiction but shares a consistent core:

Qualifying capital improvements (accepted in most jurisdictions)

Non-qualifying work (typically rejected)

The boundary line in practice: Rent board hearing officers frequently encounter the ambiguous middle — a landlord who replaced 60% of a roof and repaired the other 40%. NYC DHCR applies a “whole building improvement” standard: if the work was done building-wide and involved substantially all of the existing system, it typically qualifies. SF Rent Board hearing officers look at whether the improvement has a “useful life” extending beyond normal maintenance cycles. LA LAHD hearing officers require that the improvement be “permanent, substantial, and of general benefit to the tenants.”

Best practice across all jurisdictions: Before beginning any major work, obtain a building permit. Permit documentation is the single strongest evidence that the work was a capital improvement rather than maintenance. Permits are also required in most jurisdictions as a condition of approving the petition. Work done without a permit is frequently disqualified at the hearing stage.

New York City: Major Capital Improvement (MCI) petition (DHCR Form RA-79)

New York City’s MCI process is the most complex and heavily litigated capital improvement petition mechanism in the United States, having been the subject of continuous administrative interpretation and legislative reform for more than 40 years. The HSTPA (Housing Stability and Tenant Protection Act of 2019) made sweeping changes that fundamentally altered the economics of NYC MCIs.

Governing authority and forms

NYC MCIs are governed by the NYC Rent Stabilization Law (NYC Admin. Code §26-511(b)(9)) and the Rent Stabilization Code (RSC), 9 NYCRR §2522.4. The petition is filed with DHCR (New York State Division of Housing and Community Renewal), the state agency administering rent stabilization for NYC. The form is DHCR Form RA-79 (Petition for a Major Capital Improvement Rent Increase).

DHCR office: 92-31 Union Hall St., Jamaica, NY 11433 (main processing center) or the Manhattan District Rent Office at 25 Beaver St., New York, NY 10004. Petitions are increasingly filed electronically through DHCR’s HCR Web portal (hcr.ny.gov). In-person filing is available but paper petitions take longer to process.

Qualifying improvements for NYC MCI

DHCR publishes a list of qualifying MCI improvements in its Operational Bulletin and through formal regulatory guidance. The established list includes: roof replacement (full); boiler and/or burner replacement; elevator (new or replacement); electrical service upgrade (building-wide); plumbing (building-wide repiping); pointing and waterproofing (exterior masonry); new windows (building-wide — distinguishing these from individual apartment windows, which are IAIs not MCIs); central heating system; new intercom/door system; laundry room equipment (building-wide); new lobby flooring (building-wide); new hallway flooring (building-wide); new fire suppression system; new security system (building-wide).

Critical NYC-specific rule: The improvement must be building-wide — an improvement that benefits all tenants, not just tenants in specific units. Replacing windows in only some units, or repiping only certain apartments, typically fails the MCI building-wide standard for those units not served by the improvement.

Pre-HSTPA calculation (historical reference)

Before the HSTPA (for improvements completed before June 14, 2019 that are still within their amortization period), the MCI calculation was:

• Monthly per-room increase = eligible cost ÷ (total number of rooms in building × 84 months)
• Monthly per-apartment increase = rooms in apartment × per-room monthly increase
• Pre-HSTPA MCIs were permanent additions to the legal regulated rent

Example: $240,000 new boiler in a 30-unit building with an average of 4.5 rooms per apartment = 135 total rooms. Per-room per-month increase = $240,000 ÷ (135 × 84) = $21.16/room/month. For a 4-room apartment: $84.64/month permanent increase. For a 5-room apartment: $105.80/month permanent increase. Since this was permanent, it compounded into the base for all future RGB guideline increases — a very significant long-run value, which is why HSTPA eliminated it.

Post-HSTPA changes (2019 — applicable to all new petitions)

The HSTPA made four structural changes to MCIs:

1. Annual cap on MCI increases. The total MCI surcharge per apartment per year is capped at:

• 2% of the monthly legal regulated rent for buildings with 35 or more residential units
• 3% of the monthly legal regulated rent for buildings with fewer than 35 residential units

The cap is applied to the current monthly legal regulated rent at the time the MCI increase goes into effect. If subsequent RGB guideline increases raise the base rent, the MCI cap is re-calculated against the new base at each RGB cycle.

Example: 40-unit building (35+ units, so 2% cap applies). Unit’s current legal regulated rent: $1,800/month. Maximum MCI surcharge: $1,800 × 2% = $36/month. No matter how large the improvement cost or how many rooms, the tenant in that apartment pays no more than $36/month MCI surcharge annually under the 2% cap.

The cap resets as the base rent changes with RGB guideline increases. If the unit’s legal regulated rent increases to $1,854 at the next RGB cycle (3% guideline), the MCI cap recalculates to $37.08/month.

2. MCI surcharges are temporary, not permanent. Post-HSTPA, an MCI increase sunsets at the end of the improvement’s useful life as determined by DHCR. When the surcharge period ends, the rent decreases by the amount of the MCI surcharge. The MCI amount is not baked into the base rent going forward and does not compound with subsequent RGB increases.

DHCR’s typical useful life determinations (post-HSTPA): boiler/heating system — approximately 25 years; roof — approximately 25 years; elevator — approximately 25 years; electrical service — approximately 30 years; windows (building-wide) — approximately 25 years; plumbing repiping — approximately 30 years.

3. Six-year lookback. Improvements completed more than 6 years before the petition filing date are not eligible for inclusion in the MCI petition. This prevents landlords from filing petitions for decades-old work.

4. Tenant hardship waiver. Post-HSTPA, tenants who can demonstrate severe financial hardship can apply for a waiver or reduction of the MCI surcharge. DHCR reviews hardship applications on a case-by-case basis. This creates procedural risk for landlords: even an approved MCI petition may be partially or fully stayed for specific hardship-qualifying tenants.

NYC MCI petition process step-by-step

1. Complete DHCR Form RA-79. List every improvement for which you are seeking an MCI increase, with the date completed and the eligible cost for each.
2. Attach all contractor invoices and receipts. Each invoice must be on the contractor’s letterhead, specify the work performed and the address, and match the dollar amounts claimed on RA-79.
3. Attach all building permits and certificates of completion. NYC Buildings Department permits are required for all MCI work. Work done without a permit is presumptively ineligible.
4. If any work was done by the owner or by unlicensed workers, attach an explanation and alternative evidence of cost (materials receipts, etc.). Owner-performed labor is generally not compensable.
5. Include the building’s current rent registration records (from DHCR’s online records or your own filings).
6. Submit the completed petition to DHCR. DHCR will send a Notice of Petition to all tenants in the building, giving them 35 days to respond.
7. DHCR reviews documentation for completeness and may issue Requests for Additional Information (RFIs). Respond to all RFIs within the specified deadline — failure to respond results in denial of the petition.
8. If no tenants object and documentation is complete, DHCR may issue an Order Granting MCI Increase without a hearing. If tenants object, DHCR schedules a hearing before a hearing officer.
9. After approval, the MCI increase takes effect as specified in the DHCR order. The increase is added to the legal regulated rent for the building, subject to the 2%/3% annual cap and the post-HSTPA useful-life sunset.

Timeline: An uncontested NYC MCI petition currently takes approximately 18–30 months to process at DHCR due to the agency’s case backlog. Contested petitions (with tenant objections and hearings) routinely take 3–5 years. Plan accordingly: do not count on MCI revenue in the near term after filing.

Attorney recommendation: NYC MCI petitions are genuinely complex. Documentation errors, missed permit requirements, or incorrect cost calculations result in partial or complete denial. Most landlord attorneys who practice before DHCR charge $3,000–$8,000 per MCI petition for a small-to-medium building; larger buildings with multiple improvements can run $10,000–$20,000+ in legal fees. For a 20-unit building with a $350,000 boiler replacement, the economics usually support hiring an attorney given the stakes involved. For a 3-unit building with a $60,000 roof, the economics are marginal and a well-organized landlord with complete documentation may self-represent.

San Francisco: Capital Improvement Pass-Through petition (Admin. Code §37.7)

San Francisco’s capital improvement pass-through mechanism is governed by Administrative Code §37.7 (the Rent Ordinance’s capital improvement provisions) and administered by the San Francisco Rent Board at 25 Van Ness Ave., Room 300, San Francisco, CA 94102. Phone: (415) 252-4602.

SF’s system has two distinguishing features that make it structurally different from NYC’s MCI: (1) the cost is split 50/50 between the landlord and the tenant (the tenant pays only 50% of their pro-rata share), and (2) the pass-through was always temporary (expiring at the end of the amortization period), even before NYC adopted this approach with the 2019 HSTPA.

Coverage: which units are eligible

Capital improvement pass-throughs are available for units covered by the San Francisco Rent Ordinance — generally, residential units in buildings with a Certificate of Occupancy issued before June 13, 1979 (with significant exceptions including condominiums, new construction, and certain owner-occupied buildings). The same coverage rules that govern the annual allowable increase apply to capital improvement petitions. If your unit is not covered by the SF RSO, the capital improvement petition process does not apply; you set rent freely at market.

Qualifying improvements under §37.7

SF Admin. Code §37.7(c) defines qualifying capital improvements as permanent improvements to the building “of a substantial nature having a long, useful life.” The Rent Board has developed extensive published guidance through its Rules and Regulations and hearing officer decisions. Established qualifying improvements: new roof (full replacement); mandatory seismic retrofit (required under San Francisco’s Mandatory Soft-Story Retrofit Program for pre-1978 wooden soft-story buildings, or under the Mandatory Non-Ductile Concrete Building Retrofit Program); new boiler or central heating system; elevator modernization or replacement; new electrical service (building-wide); new plumbing (building-wide repiping); new double-pane windows (building-wide); new exterior siding; major waterproofing work; new fire suppression or fire alarm system (building-wide); new security system (building-wide). Improvements that affect only the landlord’s portion of a building, or that benefit only a specific tenant, are excluded from a building-wide petition (though they may support an individual unit petition for that specific tenant’s unit).

Non-qualifying under SF §37.7: interior painting; carpet replacement; appliance replacements in individual units; landscaping; deferred maintenance (work that should have been done years ago as ordinary upkeep); code-compliance work addressing an existing Notice of Violation (where the hazardous condition pre-dated the improvement, suggesting the landlord was already legally obligated to act).

The 50/50 cost-sharing rule and amortization periods

The SF Rent Board’s 50/50 rule: tenants pay 50% of their pro-rata share of the annual amortization. The landlord pays the other 50%. This is a permanent feature of SF’s system — unlike NYC, there is no option to pass through 100% of the cost.

SF Rent Board amortization periods (from Rent Board Rules and Regulations §12.15):

Note: The Rent Board may adjust these periods at its discretion based on the specific improvement. A boiler installed in an unusual configuration, for instance, might receive a 20-year amortization if evidence supports longer useful life.

Calculation example: mandatory seismic retrofit

Facts: 8-unit building. Mandatory soft-story seismic retrofit completed under SF’s Mandatory Soft-Story Retrofit Program. Total verified contractor cost: $216,000 (including structural engineering, permitting, and construction). All units are SF RSO-covered.

Calculation:

• 50% tenant share: $216,000 × 50% = $108,000
• Tenant share spread over 8 units: $108,000 ÷ 8 = $13,500 per unit total
• Per unit per month: $13,500 ÷ 240 months = $56.25/month per unit
• The pass-through of $56.25/month applies to each of the 8 units for 20 years
• After 20 years, the pass-through expires; the rent drops by $56.25/month

Combined with the 2026 annual allowable increase: SF RSO allowable increase is 1.4% for 2026. For a unit at $2,100/month, the annual increase is $29.40/month. The landlord would receive both the $29.40 annual increase AND the $56.25 capital improvement pass-through — a combined $85.65/month effective increase (a 4.1% effective increase over the prior rent), of which $29.40 is permanent (added to the base) and $56.25 is temporary (expires in 20 years).

SF capital improvement petition process

1. File Form CI-100 (Landlord’s Petition for Capital Improvement Rent Increase) with the SF Rent Board. Available at rentboard.sfgov.org or at 25 Van Ness Ave., Room 300.
2. Attach: building permits (required; SF DBI permit numbers and inspection sign-offs); contractor invoices (itemized); proof of payment (cancelled checks or bank records); a complete list of all residential rental units in the building with current rents and names of current tenants.
3. Simultaneous tenant notice: serve a copy of the petition and all attachments on each affected tenant. The tenant has 30 days to file a written response or objection with the Rent Board.
4. If no tenant files a response, the Rent Board may issue a Tentative Decision approving the pass-through administratively. The landlord and all tenants receive the Tentative Decision; parties have an additional period to request a hearing.
5. If any tenant objects, the Rent Board schedules an Administrative Hearing before a hearing officer. Both parties present evidence. The hearing officer issues a decision.
6. Final decisions can be appealed to the Rent Board’s Appeal Board, and then to San Francisco Superior Court.

Timeline: Uncontested SF capital improvement petitions: approximately 6–12 months. Contested petitions: 12–36 months. The SF Rent Board is generally well-staffed and more efficient than NYC DHCR or LA LAHD for capital improvement petitions.

Seismic retrofit tip: If your building is enrolled in SF’s Mandatory Soft-Story Retrofit Program or Non-Ductile Concrete Program, the retrofit was legally required — making it among the strongest possible capital improvement petition candidates. Tenants can challenge the cost but rarely the eligibility of the improvement itself.

Los Angeles RSO: Individual Rent Adjustment (IRA) petition for capital improvements (LAMC §151.07(c))

The Los Angeles Rent Stabilization Ordinance (RSO), codified at Los Angeles Municipal Code §151.07(c), permits landlords with RSO-covered units to file an Individual Rent Adjustment (IRA) Petition with the Los Angeles Housing Department (LAHD) for above-cap rent increases. Capital improvements are one of four grounds for an IRA petition (the others being increased operating costs, rehabilitation, and reduction of housing services by the tenant).

RSO coverage reminder

The LA RSO covers most residential rental units in the City of Los Angeles built before October 1, 1978 with two or more units on the parcel. Single-family homes, condominiums sold to individual owners (typically exempt), newly constructed buildings (post-1978), and certain other categories are exempt. Landlords with units in unincorporated Los Angeles County are subject to LACDA oversight, not LAHD, and should check the applicable LACDA ordinance for their specific city or unincorporated area. See our complete Los Angeles RSO 2026 guide for coverage analysis.

Qualifying improvements under the LA RSO IRA

LAMC §151.07(c)(4) defines qualifying capital improvement as “any permanent improvement to the rental unit or common areas that benefits the tenants and for which the landlord is not entitled to reimbursement under the general services and maintenance provision of this chapter, and which has a useful life of at least five years.” LAHD regulations further require that the improvement be in addition to ordinary maintenance and repair — not a substitute for work the landlord was already legally obligated to perform.

LAHD’s published examples of qualifying capital improvements: new roof; seismic retrofit; new plumbing (building-wide); new electrical system (building-wide); new boiler / central heating; new HVAC; new elevator; new laundry facilities; new driveway or parking structure; structural improvements; ADA accessibility improvements. Code-compliance work required because of a pre-existing Notice of Violation issued by LADBS or LAHD is specifically excluded because the landlord was already legally obligated to perform it before the capital improvement was undertaken.

IRA petition process

1. File the IRA Petition online via the LAHD Housing Portal (housingis.lacity.org) or in person at a LAHD public counter (200 N. Spring St., Los Angeles; or 3550 Wilshire Blvd., Suite 1500, Los Angeles). LAHD also maintains district offices with public counter access.
2. Pay the filing fee. As of 2026, LAHD charges approximately $93–$130 per affected residential unit (verify current fee schedule at housing.lacity.gov before filing).
3. Attach complete documentation: itemized contractor invoices; building permits (Los Angeles Department of Building and Safety permit numbers and final inspection sign-offs); proof of payment; a list of all affected RSO-covered units with current rents; APN (Assessor Parcel Number) and building address.
4. LAHD serves all tenants in the building with the petition and supporting documents. Tenants have 15 days to file a written response.
5. A LAHD hearing officer reviews the petition and tenant responses. If no substantive tenant objection is filed, the hearing officer may approve the petition administratively. If tenants object, the hearing officer schedules an in-person hearing at a LAHD district office.
6. The hearing officer issues a written Rent Adjustment Order specifying: (a) whether the capital improvement qualifies; (b) the allowable cost basis (LAHD may disallow costs not supported by documentation); (c) the monthly above-cap surcharge per unit; (d) the duration of the surcharge (based on LAHD’s amortization determination); and (e) the effective date.

Timeline warning: The LA RSO IRA process is notoriously slow. As of 2026, LAHD’s hearing officer caseload typically produces timelines of 12–18 months for uncontested petitions and 2–4 years for contested petitions. Plan capital improvements accordingly: do not budget for IRA revenue in the same fiscal year you complete the improvement.

Cost strategy: The long timeline of the IRA process makes it economically unattractive for smaller improvements in small buildings. A 4-unit building where the landlord spent $90,000 on a new roof, generating perhaps a $75/unit/month temporary surcharge, may net only $3,600/year in incremental rent during the amortization period — which, discounted at a 2-year wait plus $4,000–$8,000 in attorney fees, barely breaks even. The IRA process makes the most economic sense for large-scale capital projects (seismic retrofit, major structural work) in buildings with 8 or more units.

Interaction with the 2026 RSO annual cap

The 2026 LA RSO annual allowable increase is 3% (for RSO-covered units in the City of Los Angeles). The capital improvement surcharge from an approved IRA is in addition to the annual 3% increase. A landlord who receives an approved IRA surcharge in the same year as the annual guideline increase may collect both. However, the IRA surcharge applies only to units covered by the petition; the annual allowable increase applies to all RSO-covered units in the building regardless of whether an IRA petition was filed.

Oakland: Rent Adjustment Program capital improvement petition (OMC §8.22)

Oakland’s rent control system is administered by the Oakland Rent Adjustment Program (RAP) under Oakland Municipal Code Chapter 8.22. The RAP administers both the annual rent adjustment (CPI-based) and petitions for above-cap adjustments including capital improvement pass-throughs.

Coverage

The Oakland Rent Adjustment Law covers most multi-unit residential properties in Oakland with a Certificate of Occupancy on or before December 31, 1995 (the coverage date was expanded from pre-1983 to pre-1996 construction in 2020 by Measure Y). Single-family homes occupied by the owner are generally exempt. Subsidized housing covered by a regulatory agreement may be exempt. As with SF and LA, verify coverage for each specific parcel before filing.

Oakland annual rent adjustment and the Capital Improvement petition

Oakland’s annual rent adjustment is tied to 60% of the Oakland CPI (Consumer Price Index for All Urban Consumers, Oakland-Hayward-Berkeley CBSA). For 2026, this figure is approximately 2.7–3.1% (varying by CPI publication date; verify current figure with Oakland RAP before filing). Above-cap increases are available via petition, including capital improvement petitions.

To file a capital improvement petition with Oakland RAP:

1. File the Petition for Rent Increase Based on Capital Improvements with Oakland RAP (250 Frank H. Ogawa Plaza, Suite 5313, Oakland, CA 94612, or electronically via the RAP online portal at oaklandca.gov/topics/rent-adjustment-program).
2. Attach: contractor invoices and proof of payment; Oakland building permits and final inspections; description of improvements and their useful life; list of all covered units in the building.
3. Oakland RAP serves the petition on all affected tenants; tenants have 30 days to respond.
4. An Oakland RAP hearing officer determines whether the improvement qualifies, the allowable cost basis, and the amortization period.
5. Approved petitions result in an above-cap monthly per-unit surcharge for the duration of the amortization period.

Oakland’s capital improvement petition process is generally faster than LA’s, with uncontested petitions typically resolved in 9–18 months. However, Oakland RAP is a smaller agency and timelines vary substantially with staffing levels.

Oakland’s Just Cause for Eviction interaction: Oakland has a strong just-cause eviction ordinance (OMC §8.22.360) covering all buildings with two or more units, regardless of age. A landlord who uses a capital improvement as a pretext for displacing tenants (claiming “substantial rehabilitation” when the actual intent is to flip units to market rate) faces significant exposure under Oakland’s OMC §8.22.360(a)(8) just-cause exception for substantial rehabilitation — which requires actually making a unit uninhabitable for the duration of renovation, not merely undertaking capital improvements while tenants remain in residence.

Washington DC: Capital Improvement surcharge petition (DC Code §42-3502.14)

Washington DC’s Rental Housing Act (DC Code §42-3502 et seq.) governs rent control for most residential units in DC and includes a capital improvement surcharge mechanism at DC Code §42-3502.14. The petition is filed with the DC Rental Housing Commission (or processed through the Office of the Rent Administrator), which adjudicates above-cap increase requests.

DC rent control coverage reminder

DC’s Rental Housing Act covers most privately owned rental units in DC with four or more units (two or more units in some circumstances), with the notable exception of buildings newly registered after 1975, buildings with two or fewer units where one unit is owner-occupied, buildings undergoing substantial rehabilitation under §42-3502.14(c), and federally subsidized housing. See our complete DC Rental Housing Act landlord guide for the full coverage analysis and 2026 annual cap calculation (~6.8%).

DC Capital Improvement petition process

Under DC Code §42-3502.14, a landlord may petition the Rent Administrator for a surcharge above the general CPI-based annual adjustment based on:

• Capital improvements to the rental unit or building
• Substantial rehabilitation of the building
• Increased operating and maintenance costs not attributable to the landlord’s actions

For capital improvements, the process is:

1. File a Petition for a Rent Increase Based on Capital Improvement with the DC Office of the Rent Administrator (1800 Martin Luther King Jr. Ave. SE, Washington, DC 20020; or via the DCRA online permitting and licensing portal).
2. Attach contractor invoices and receipts, DC building permits and certificates of occupancy for the improvement work, itemized cost breakdown, and a description of how each improvement benefits the tenants.
3. The Rent Administrator serves notice on all affected tenants; tenants have 30 days to respond.
4. If no tenant objects, the Rent Administrator may approve administratively. If contested, a hearing is scheduled before a hearing examiner.
5. Approved petitions result in an above-cap surcharge per unit per month for the duration of the amortization period (determined by the Rent Administrator based on the improvement’s useful life).

DC-specific consideration: DC’s general annual adjustment is already relatively generous compared to SF (1.4%) and NYC (2.75%): the DC Rental Housing Act annual maximum is tied to the DC-Metro CPI-U, which ran approximately 6.8% in 2026. In practice, DC landlords with RSO units seek capital improvement petitions primarily for major capital projects (seismic upgrades, major structural work) where the cost significantly exceeds what the annual CPI allowance provides.

Berkeley and Santa Monica

Berkeley Rent Board

Berkeley’s Rent Stabilization and Eviction for Good Cause Ordinance (Berkeley Municipal Code §§13.76.010–13.76.200) covers most residential rental units in Berkeley and includes a capital improvement pass-through mechanism administered by the Berkeley Rent Board (2125 Milvia St., Berkeley, CA 94704; phone: (510) 981-7368).

Berkeley’s capital improvement petition is filed using the Rent Board’s standard Petition for Approval of Rent Increase. Berkeley’s annual general allowable increase (60% of the Oakland-Hayward-Berkeley CPI) is separate from and additive to an approved capital improvement pass-through. Berkeley’s amortization approach is similar to San Francisco’s but without the statutory 50/50 split — Berkeley Rent Board hearing officers determine the appropriate cost allocation based on the specific improvement and its benefit to tenants.

Berkeley’s process is generally less formal than SF’s but tends to be thorough. Uncontested petitions run 6–12 months. Berkeley has a notably high rate of tenant organization, and contested capital improvement hearings can be contentious. Building permits are required documentation in Berkeley as in all other jurisdictions.

Santa Monica Rent Control Board

Santa Monica’s Rent Control Charter Amendment (SMMC §§4.20.010–4.36.100) covers residential rental units in Santa Monica (generally those with a Certificate of Occupancy before April 10, 1979). Capital improvement pass-throughs are governed by SMMC §§4.20.030 (definitions) and 4.36.060 (capital improvement petitions), administered by the Santa Monica Rent Control Board (1685 Main St., Room 202, Santa Monica, CA 90401; phone: (310) 458-8751).

The Santa Monica system permits landlords to petition for a temporary rent increase based on the amortized cost of qualifying capital improvements. The Rent Control Board’s hearing officer determines the eligible cost basis, amortization period, and per-unit monthly surcharge. The pass-through is temporary and expires at the end of the amortization period. Santa Monica’s process is similar in structure to Berkeley’s — a single administrative petition, tenant notice, optional hearing. Uncontested petitions typically resolve in 6–12 months.

Cross-jurisdiction comparison table

Notes on the comparison:

• NYC’s 2%/3% annual cap is unique among these jurisdictions — it is the only city with a hard statutory ceiling on the annual MCI surcharge regardless of improvement cost. In SF, Oakland, Berkeley, and Santa Monica, the monthly pass-through is formula-determined (typically cost ÷ units ÷ amortization months with a cost-split), and there is no separate annual percentage cap on top of that formula.
• SF’s 50/50 split is the only system where the cost-sharing ratio is fixed by statute. All other jurisdictions leave the cost allocation to hearing officer discretion, which in practice usually results in 70–100% of the eligible cost being passed through to tenants.
• LA’s timeline is the worst in this comparison. The 12–18 month median for uncontested petitions reflects LAHD’s persistent staffing constraints and high petition volume.

10-step capital improvement petition checklist

1. Verify coverage. Confirm the affected units are covered by the relevant rent ordinance. Capital improvement petitions are not available for exempt units (newly constructed buildings, owner-occupied SFHs, exempt condominiums). Check the city-specific coverage rules before filing.
2. Classify the improvement correctly. Before beginning construction, confirm the planned work qualifies as a capital improvement (permanent, benefits tenants, extends useful life) rather than maintenance or repair. If in doubt, call the relevant rent board and describe the scope of work; staff can often advise on likely eligibility.
3. Obtain a building permit BEFORE construction begins. No permit = strong risk of petition denial in all jurisdictions. The permit is both proof of the scope of work and evidence of the improvement’s permanence.
4. Preserve all contractor documentation. Require itemized invoices from every contractor. Invoices must specify the address, scope of work performed, and amount charged. Lump-sum invoices (“renovation work: $80,000”) are frequently challenged; itemized invoices (“tear-off existing roof, install 30-year architectural shingles, new flashing, underlayment: $80,000”) are far less likely to be disputed.
5. Keep proof of payment. Bank records, cancelled checks, or wire transfer confirmations for every invoice. DHCR, LAHD, and SF Rent Board hearing officers routinely disallow costs not supported by proof of actual payment.
6. Get the final permit inspection signed off. The final permit inspection sign-off from the relevant city building department (NYC DOB, SF DBI, LA LADBS, Oakland Building Services, DC DCRA) is typically required as part of the petition. Do not delay the close-out inspection — an open permit can delay or disqualify a petition.
7. File the petition promptly after completion. NYC’s 6-year lookback and similar statutes of limitation in other jurisdictions mean delay is costly. File within 6 months of improvement completion to maximize the time available for the petition to process before the lookback window potentially closes on future improvements.
8. Serve tenants properly. In all jurisdictions, tenants must receive notice of the petition with supporting documentation. Serve by certified mail or personal delivery and retain proof of service. Procedural defects in tenant service can void a petition or restart the clock.
9. Respond to all agency requests for additional information. DHCR RFIs, LAHD supplemental document requests, and SF Rent Board inquiries must be answered within the specified deadlines. Failure to respond typically results in automatic denial or delay.
10. Calendar the surcharge expiration date. On the day the petition is approved, calendar the date on which the surcharge expires (end of amortization period). Continuing to charge the surcharge after expiration is an overcharge, subject to refund plus penalties.
