The Oakland number for the year is 2.3 percent. For covered units, that is the allowable annual increase from August 1, 2026 through July 31, 2027. Last year’s was 0.8 percent.
The number is the easy part. What trips Oakland landlords up is everything the city attaches to the notice, and a registration step that has to be done before any increase is valid.
Which buildings the rent rules cover
Oakland runs two separate protections. The Rent Adjustment Ordinance limits rent increases. The Just Cause for Eviction Ordinance limits when you can end a tenancy. Plenty of units are under the second and not the first.
The city’s own guide to its rental laws lists what is exempt from the rent limits:
- Single-family homes and condos rented as one unit, not room by room.
- Buildings built after January 1, 1983, where the unit was newly constructed or created from space that was not residential before.
- Units whose rent another agency already controls, such as Section 8, and resident-controlled nonprofit cooperatives.
In practice that leaves most rental units in multifamily buildings built before 1983. A 1920s duplex is covered. A 1990 fourplex is not, at least not by the city’s cap.
The eviction side is broader and has its own exemptions. The Oakland just cause eviction rules page covers it.
How the annual increase works
Each spring the Rent Adjustment Program publishes the next year’s figure, and it runs August 1 to July 31. Since 2022 the formula has been 60 percent of the change in CPI, or 3 percent, whichever is lower.
The timing rules are strict:
- One increase per unit in any 12-month period.
- The first increase can take effect no earlier than 12 months after the tenant moved in.
- No increase until at least six months after the tenant first received the RAP Notice. A landlord who never gave it at move-in has to give it now and wait six months.
- At least 30 days’ written notice.
- On a fixed-term lease, the increase waits for the term to end unless the lease allows it.
When every tenant in a unit is new, the rent can be set at market. If anyone from the prior tenancy is still there, the ordinance limits still apply.
What goes in the envelope
An Oakland rent increase notice on a covered unit is a packet, not a letter.
- The RAP Notice. Required at the start of every tenancy and with every rent increase. It comes in English, Spanish, and Chinese, and the city publishes the current version.
- A current business tax certificate. Since April 15, 2025, an owner who is delinquent on business taxes cannot issue a rent increase. A CPI-only increase needs the certificate or a copy of a payment plan with the city. An increase that uses banked amounts needs the certificate.
- A registered unit. Covered units must be in the rent registry, renewed every year by March 1. A unit that is not registered cannot be increased.
Miss any one of them and the tenant has grounds to contest. Tenants now have 180 days from service of the notice to file a petition challenging it, up from 90.
Banking changed on January 1, 2026
Banking means taking an annual increase you skipped in an earlier year. Oakland allows it without a petition, with limits that tightened this year:
- Banked increases now expire after five years, down from ten.
- Banking generally cannot transfer to a new owner. The exception is an inheritance between close family members, and only if the new owner holds the property at least a year.
- No single year’s increase can exceed three times the current CPI figure.
- Any notice that includes banked amounts needs the business tax certificate.
An owner can also petition for more for capital improvements, increased operating costs, uninsured repairs, or fair return. Whatever the total, an annual increase on a covered unit cannot exceed the state cap, which the city lists as 8.8 percent from August 1, 2026.
Units outside the program
A post-1983 building, or a house rented whole, is outside the city’s cap. That usually puts it under the state’s. AB 1482 covers most housing more than 15 years past its certificate of occupancy, and for Alameda County the cap from August 1, 2026 is 8.8 percent (Cal. Civ. Code § 1947.12). Units under Oakland’s lower cap are exempt from AB 1482 for the same reason (§ 1947.12(d)(3)).
A house can be exempt from the state cap as well, but only with the exact clause the statute requires in the lease. Is my property exempt from AB 1482 covers that clause. For the arithmetic, see how to calculate a legal rent increase in California or run the AB 1482 calculator.
The short checklist
Before any Oakland increase goes out: confirm the building’s coverage, check the registry entry is current, check the business tax status, attach the RAP Notice, and count 30 days from delivery. Oakland is one of several Bay Area cities with its own ordinance; the California rent control city list shows the rest, and the AB 1482 rent increase limits page covers the state cap.
This is general information, not legal advice. Rules change and local ordinances vary. Confirm current requirements with your city, county, or an attorney before you act.
