Oakland Rent Control for Buyers and Owners: RAP, Just Cause, Exemptions

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

Oakland rent control comes from two city laws that a buyer has to check separately: the Rent Adjustment Ordinance, which limits increases for existing tenants, and the Just Cause for Eviction Ordinance, which limits when a tenancy can end. For August 1, 2026 through July 31, 2027, the city’s annual CPI increase is 2.3%, and units that are not registered with the Rent Adjustment Program (RAP) cannot receive any increase. Many buildings that are exempt from the rent limits are still covered by Just Cause.

Both ordinances sit in Oakland Municipal Code Chapter 8.22 and are administered by RAP. This page reads them from the buyer’s side: how to tell whether each unit is covered, what the current numbers are, what changes when ownership transfers, and which documents to request before you remove contingencies. For other East Bay cities, see our East Bay rent stabilization comparison.

Two ordinances, two coverage tests

Coverage is decided unit by unit, not building by building. A unit can fall under rent limits and Just Cause, under Just Cause only, or under neither. RAP’s own coverage chart (January 2026) lists apartments, condos, single-room occupancy units, new construction, owner-occupied duplexes and triplexes, single-family homes, subsidized housing and shared kitchen or bath arrangements as separate categories, because each is treated differently.

The city states that every unit covered by the Rent Adjustment Program is also covered by Just Cause, and that units outside RAP may still be covered by Just Cause. In practice, start by assuming both apply and then document any exemption with paper, not with the listing description.

Unit type	Rent Adjustment (rent limits)	Just Cause	What to verify
Older multifamily (2+ units)	Generally covered	Covered	Registry filings, RAP notices, rent history
Units with a certificate of occupancy on or after January 1, 1983	Exempt from rent limits (new construction certificate available)	Covered once the certificate is more than 10 years old	Certificate of occupancy for ground-up construction
Ground-up new construction within the past 10 years	Exempt	Exempt	Certificate of occupancy or RAP Certificate of Exemption
Single-family home or condo that can be sold separately	Usually exempt under Costa-Hawkins	Covered	How the prior tenancy ended; code violations
Owner-occupied duplex or triplex	Exemption removed by a 2019 interim emergency ordinance; confirm current status with RAP	Covered since Measure Y	Owner occupancy, base rent history
Fully owner-occupied home with no tenants	Exempt	Exempt	Proof of residency if claiming a registry exemption

Treat the table as a map for questions, not a ruling. RAP decides exemptions, and the city’s Business Tax Office, which bills the program fee, says it does not.

New construction

Oakland’s rent limits exempt units built with a certificate of occupancy issued on or after January 1, 1983, and an owner can petition RAP for a Certificate of Exemption on that basis. Just Cause works on a rolling clock instead. RAP’s January 2026 flyer says Measure V extended eviction protections to most units built after 1995, leaving only ground-up construction with a certificate of occupancy from the last 10 years outside Just Cause.

The certificate must be for construction from the ground up. A unit created by converting existing residential space does not qualify for the new-construction exemption, so an ADU carved out of a basement is not “new” in this sense.

Single-family homes and condos

Under the state’s Costa-Hawkins Rental Housing Act, Civil Code section 1954.52, an owner may set the initial and all later rents for a unit that is separately alienable from any other dwelling, such as a house on its own lot or a condominium. That exemption has exceptions. It does not apply where the owner ended the prior tenancy by notice, and it does not apply to a unit with serious code violations left unabated for six months before the vacancy.

RAP says it no longer issues Certificates of Exemption for single-family homes, though most remain exempt from rent limits. The same section of Costa-Hawkins preserves a city’s power to regulate the grounds for eviction, which is why these homes still fall under Just Cause.

Owner-occupied duplexes and triplexes

Measure Y, approved by Oakland voters on November 6, 2018 and effective December 21, 2018, removed the Just Cause exemption for owner-occupied duplexes and triplexes. On February 8, 2019, the City Council adopted an interim emergency ordinance removing their rent adjustment exemption as well, with the November 6, 2018 rent as the base rent. The city’s page says that ordinance would last 180 days or until a permanent ordinance took effect, and it does not say what followed, so confirm the building’s current status with RAP and your attorney. The program fee exemption covers only fully owner-occupied units, so plan on paying the fee for the rented units.

Allowable rent increases for 2026–2027

Oakland’s annual increase is 60% of the change in the Consumer Price Index or 3%, whichever is lower. The city set it at 2.3% effective August 1, 2026, up from 0.8% the year before. RAP also says a combined increase can never exceed the state cap. The California Attorney General’s rent cap chart sets that cap at 8.8% for Alameda County for August 1, 2026 through July 31, 2027, which matches the figure on the city’s page.

Notice: at least 30 days’ written notice, with a copy of the RAP Notice attached to every increase notice.
Frequency: one increase in any 12-month period, and none until 12 months after the tenant moved in.
RAP Notice timing: no increase until six months after the tenant was served the RAP Notice.
Registration: units not registered with RAP cannot receive increases.
Leases: a fixed-term lease generally delays an increase until it ends, unless the lease allows one sooner.
Vacancy: if all original occupants have left, the owner may set a new market rent; if any remain, the ordinance limits still apply.

Banking and the change at transfer

Owners may defer annual increases and impose them later. From January 1, 2026, banked increases expire after five years instead of ten, and no single year’s increase can exceed three times the current CPI figure. Notices that include banked amounts need a current Oakland Business Tax Certificate attached.

The rule that matters most to a buyer took effect December 24, 2024: banked CPI increases expire when ownership transfers. The only exception is a qualifying inheritance among spouses, parents, siblings, children and stepchildren, where the new owner holds the property at least a year. Do not price a purchase on the seller’s banked increases.

Increases above CPI

An owner who wants more than the CPI increase has to justify it, for example through capital improvements, uninsured repairs, increased housing service costs or a fair-return petition. Capital improvement pass-throughs are limited to 70% of the cost, amortized over the improvement’s useful life, and the owner must prove payment. Since December 24, 2024, a tenant has 180 days, rather than 90, to petition against an increase.

The rent registry and the program fee

Oakland requires owners to register covered units built before April 1, 2016 and to renew each year by March 1. The list includes units in buildings of two or more units, condominiums and single-family homes, rented ADUs and in-law units, rooms rented under separate leases of more than 30 days, and SRO units. The first registration deadline was July 3, 2023.

Some units may claim an exemption from registering instead, including fully owner-occupied homes with no rented rooms, units vacant and unavailable for the whole July-to-June fiscal year, and ground-up new construction with a certificate of occupancy on or after April 1, 2016. Each claim is subject to verification.

The Rent Adjustment Program fee is $137 per unit per year, due January 1 and delinquent after March 1. Owners who pay on time may pass half of it to the tenant. Fully owner-occupied units and the exempt new construction described above do not owe it.

Just Cause: what ends a tenancy in Oakland

Oakland’s Just Cause for Eviction Ordinance began as Measure EE, the Just Cause Initiative Ordinance No. 12537 enacted November 5, 2002. It lists ten grounds: nonpayment of rent, a continued material lease violation after written notice, substantial damage, continued disturbance, illegal use, refusal of lawful entry after 24 hours’ written notice, owner move-back under a written agreement, owner or relative move-in, withdrawal of the unit under the Ellis Act, and substantial repairs that cannot be done with the tenant in place.

The state’s Tenant Protection Act does not stack on top. Civil Code section 1946.2(i) says a property subject to a local just cause ordinance adopted on or before September 1, 2019 follows the local ordinance, and no property is subject to both. Our just cause guide for landlords explains the statewide rules that apply elsewhere.

Owner and relative move-in

Owner move-in is one of the most regulated grounds. The ordinance bars it against tenants who are 60 or older, disabled or catastrophically ill, and the city’s regulations tie that protected status to more than five years in the unit. An owner may still proceed if the owner or the moving relative also has protected status, or if every other unit is already occupied by a protected tenant.

The termination notice must list all real property the intended occupant owns, in Oakland or elsewhere, the address of any homeowner’s exemption, the unit’s lawful rent and the tenant’s relocation rights.
Within 30 days after the tenant leaves, the owner files a certificate with RAP stating the rent on the vacate date.
The owner or relative must move in within three months and file an occupancy certificate within 30 days of moving in.
Continued-occupancy certificates are due every 12 months for 36 months, with proof such as a driver’s license at that address.
If the unit is later re-rented, the owner files a re-rental certificate within 30 days stating the new rent.

Late or missing filings can lead to administrative citations and civil penalties. Because owner move-in is so procedural, it is rarely a quick path to delivering a vacant unit, and a negotiated move-out is often discussed instead. Our page on cash for keys agreements covers how those agreements generally work.

Relocation payments

Owner and relative move-ins and other no-fault terminations require relocation payments from the owner. For July 1, 2026 through June 30, 2027, the base amounts are $8,293.13 for a studio or one-bedroom, $10,206.93 for a two-bedroom and $12,599.18 for three or more bedrooms. Households with lower-income, elderly or disabled tenants, or minor children, receive one additional $2,500 payment per unit.

How AB 1482 fits with Oakland’s rules

California’s statewide rent cap and just cause law, AB 1482, mostly sits behind Oakland’s ordinances. For just cause, the local ordinance controls under section 1946.2(i). For rent, Oakland’s CPI limit is lower than the state cap for covered units, so it governs, and RAP adds that combined increases may never exceed the state limit.

The state law matters most for units outside Oakland’s rent limits, such as post-1983 buildings that are no longer new enough to be exempt from the state cap. Check those units against the 15-year rolling exemption and the other tests on our AB 1482 page for owners. A separately sellable house or condo can be exempt from the state cap only if its owner is an eligible type and the tenant received the statutory written notice.

Due diligence before you remove contingencies

Rent rules change what the income is worth, so verify them during the investigation period. Ask the seller, through the listing agent, for:

A rent roll by unit showing move-in date, current rent, last increase date and amount, deposits and any concessions.
Copies of every lease, every rent increase notice and proof the RAP Notice was served on each tenant.
Rent registry confirmations for the current year and receipts for the RAP fee and Oakland business tax.
Any RAP petitions, decisions or Certificates of Exemption, and any pending eviction or relocation matters.
The certificate of occupancy for any unit treated as new construction.
Signed tenant estoppel certificates confirming rent, deposit and lease terms; see our guide to tenant estoppel certificates.

Underwrite the building on the rents you can lawfully collect today plus the allowable increase, not on market rent. Banked increases do not survive the sale, and turnover depends on tenants choosing to leave. Our rental property analysis guide walks through the math, and buying property with tenants in place covers showings, notices and the transfer of deposits.

Financing two- to four-unit buildings has its own rules on counting rental income; see financing 2–4 unit properties. Oakland also charges its own transfer tax on top of the county’s, which our Alameda County city transfer tax guide explains.

Questions people ask

Does Oakland have rent control?

Yes. The Rent Adjustment Ordinance limits increases for existing tenants in covered units, and the Just Cause for Eviction Ordinance limits when tenancies can end. Both are in Oakland Municipal Code Chapter 8.22 and are run by the Rent Adjustment Program.

How much can Oakland landlords raise rent in 2026?

For covered units, the CPI increase effective August 1, 2026 is 2.3%. Increases above that require banking or a justification such as capital improvements, and the combined increase cannot exceed the state cap, which is 8.8% in Alameda County from August 1, 2026 through July 31, 2027.

Are single-family homes exempt from Oakland rent control?

Most single-family homes and condos are exempt from the rent limits under Costa-Hawkins, but they are still covered by Just Cause. The exemption can be lost if the owner ended the prior tenancy by notice or left serious code violations unabated.

Do banked rent increases transfer to a new owner?

No. Since December 24, 2024, banked CPI increases expire when ownership transfers, except in a qualifying inheritance between close family members who keep the property at least a year.

Can I buy an Oakland duplex and move into one unit?

Buying is not the issue; removing a tenant is. Owner move-in requires a just cause notice, relocation payments, RAP filings and three months to move in, and it is barred against protected tenants who are 60 or older, disabled or catastrophically ill.

Do I have to register an Oakland rental?

Covered units built before April 1, 2016, including condos, single-family homes, ADUs and rented rooms, must be registered and renewed by March 1 each year. An unregistered unit cannot receive a rent increase.

What is the Oakland RAP fee?

The fee is $137 per unit per year, due January 1 and delinquent after March 1. An owner who pays on time may pass half of it through to the tenant.

Does AB 1482 apply in Oakland?

Oakland’s Just Cause ordinance predates September 1, 2019, so it controls instead of the state just cause law. The state rent cap matters mainly for units outside Oakland’s rent limits that don’t qualify for a state exemption.

Oakland rules change often, and two buildings on the same block can be covered differently. This page is general information, not legal advice. Before you rely on a unit’s exemption, a banked increase or an owner move-in plan, have a California landlord-tenant attorney review the building’s leases, notices and RAP filings.
