how much landlord raise rent california is one of the most common questions renters are asking right now. Many tenants just got a rent increase notice, or expect one soon. The good news is that California has a statewide rent cap.
It covers millions of apartments and many rental homes. However, the exact limit depends on where you live, how old your building is, and whether your city has its own rent control. If you want to know how much landlord raise rent california law allows this year, you need to check a few key facts. This guide explains them in plain English.
The rules below apply to rent increases from August 1, 2026, through July 31, 2027. Knowing how much landlord raise rent california rules allow can help you spot an illegal increase before you pay it.
The Statewide Cap: How Much Landlord Raise Rent California Law Allows in 2026
California’s main rent cap comes from the Tenant Protection Act of 2019, also called AB 1482. It is found in California Civil Code Section 1947.12. Under this law, your landlord can raise rent by 5% plus the local inflation rate. However, the total can never go above 10% in any 12-month period.
Inflation is measured by the Consumer Price Index, or CPI. The CPI tracks how much everyday prices go up. The law uses the change in regional CPI from April of last year to April of this year. As a result, the cap changes every August 1 and differs by region.
For example, a tenant in Los Angeles County has a different cap than a tenant in Riverside. In most cases, the 2026 caps land between about 8% and 9%. Your landlord can also split the increase into no more than two raises in 12 months. The combined total still cannot go over the cap. This law is set to stay in effect until January 1, 2030.
Regional Caps, Local Rent Control, and Exemptions
To figure out how much landlord raise rent california rules allow for your unit, start with your region. The table below shows the reported AB 1482 caps for increases taking effect August 1, 2026, through July 31, 2027. Always confirm with your county or city housing office.
| Region | Max Increase (Aug 1, 2026 – Jul 31, 2027) |
|---|---|
| Los Angeles / Orange County | 8.7% |
| San Francisco Bay Area | 8.8% |
| San Diego County | 8.2% |
| Riverside / San Bernardino | 8.1% |
| Rest of California | 8.6% |
Many cities have stricter local rent control. If your unit is covered by a local law, the lower limit usually applies. For example, the Los Angeles Rent Stabilization Ordinance (RSO) allows a 3% increase from July 1, 2026, through June 30, 2027. LA’s new formula now caps RSO increases between 1% and 4%. In San Francisco, the SF Rent Board set the allowable increase at 1.6% from March 1, 2026, through February 28, 2027.
Some rentals are exempt from AB 1482. Typically, these include units built in the last 15 years. Single-family homes and condos owned by individuals may also be exempt. However, the landlord must give you a written exemption notice for that to apply. Owner-occupied duplexes are usually exempt too. If you never got a written notice, you may still be covered.
What to Do If You Get a Rent Increase Notice
First, check the notice period. Under California Civil Code Section 827, a month-to-month tenant must get at least 30 days’ written notice for an increase of 10% or less. An increase over 10% requires at least 90 days’ notice. If you have a fixed-term lease, rent usually cannot go up until the lease ends. The only exception is if your lease allows it.
Next, do the math. Multiply your current rent by your region’s cap. For example, $2,000 times 8.7% equals $174. So the highest legal new rent in LA County would typically be $2,174. If your notice asks for more, that is a red flag. Knowing how much landlord raise rent california law permits gives you a clear number to compare.
