How Often Can Landlords Raise Rent in California in 2026?

For owners and renters alike, rent increases in California come with a web of rules — and in Los Angeles, those rules just changed in a big way for 2026. So how often can a landlord actually raise the rent, and by how much?

The short version: in rent-controlled and AB 1482-covered housing, a landlord can raise rent once every 12 months, and the amount is capped. Statewide, AB 1482 limits increases to 5% plus regional inflation, or 10%, whichever is lower. In the City of Los Angeles, the cap is far tighter — currently 3% — and the rules were just overhauled. Here’s how it all fits together in 2026.

How Often Can a Landlord Raise Rent in California?

For housing covered by rent control — whether the statewide Tenant Protection Act or a local ordinance — rent can generally be raised only once in any 12-month period, with proper written notice. How much it can go up depends entirely on which set of rules applies to the building, so the first task is always to identify the right jurisdiction.

The Statewide Cap: AB 1482 (Tenant Protection Act)

California’s Tenant Protection Act (AB 1482) sets a statewide ceiling on annual rent increases: 5% plus the regional Consumer Price Index (CPI), or 10% — whichever is lower. The CPI piece is set regionally and resets every year, so the exact figure moves; for the Los Angeles area it currently works out to about 8% for increases effective August 2025 through July 2026. (The California Department of Finance publishes the applicable CPI.)

AB 1482 applies to most rental housing more than 15 years old — and that’s a rolling date, not a fixed year, so it keeps moving forward. Key exemptions include:

• new construction less than 15 years old;
• single-family homes and condos not owned by a corporation, REIT, or corporate-member LLC — provided the required notice is in the lease;
• owner-occupied duplexes;
• deed-restricted affordable housing.

AB 1482 also requires a just cause to end most tenancies. One crucial point: being exempt from AB 1482 does not mean a property is exempt from a stricter local ordinance — and where a local cap applies, the local cap wins.

Los Angeles Rent Control: The RSO and the 2026 Overhaul

If a building is in the City of Los Angeles and was built on or before October 1, 1978, it’s almost certainly covered by the city’s Rent Stabilization Ordinance (RSO) — and the RSO cap is far lower than the statewide one.

For the period July 1, 2025 through June 30, 2026, the allowable RSO increase is 3%. And in late 2025 the City Council overhauled the formula, with major changes that took effect February 2, 2026:

• the extra 1% for gas and 1% for electric that landlords could previously add are eliminated;
• the 10% increase for an additional dependent is eliminated;
• starting July 1, 2026, the annual increase will be calculated at 90% of CPI, with the maximum cut to 4% (down from 8%) and a floor of 1%.

In plain terms: for now the RSO number is a flat 3% with no add-ons, and going forward the ceiling is 4%. For owners, that means tighter, simpler limits — and a real squeeze on margins as insurance, utilities, and labor costs keep climbing.

Unincorporated LA County and Other Cities

Not every LA-area property follows the City of LA’s rules. The cap depends on exactly where the building sits:

• Unincorporated LA County (for example, Marina del Rey) falls under the county’s Rent Stabilization and Tenant Protection Ordinance (RSTPO). For July 2025–June 2026, the cap is 1.93% for fully covered units, 2.93% for self-certified small landlords, and 3.93% for luxury units.
• Other incorporated cities — Santa Monica, Beverly Hills, West Hollywood, Culver City — each have their own rent control with their own annual caps, so always check the specific city.

Which Rules Apply to Your Building?

Because the patchwork is confusing, here’s the quick way to find your cap:

• City of LA, built on or before Oct. 1, 1978? → RSO (currently 3%). Check status at zimas.lacity.org.
• Unincorporated LA County? → county RSTPO (1.93%–3.93%).
• Another city with rent control? → that city’s ordinance.
• None of the above, but more than 15 years old and not exempt? → AB 1482 (5% + CPI, or 10%).
• New or otherwise exempt? → market rate, with proper notice.

Rent Increase Notice Requirements

Whatever the cap, California requires written notice before an increase takes effect: 30 days for an increase of 10% or less over 12 months, and 90 days for anything more. Local ordinances can add their own filing or documentation requirements on top of that.

What This Means for Los Angeles Property Owners

The 2026 changes lower the ceiling, strip out the add-ons, and leave owners with less room to keep pace with rising costs — and the rules genuinely differ from one block to the next. Charging even slightly over the cap, using the wrong notice period, or misjudging which ordinance applies can invalidate an increase or trigger a complaint and penalties.

Frequently Asked Questions

How much can a landlord raise rent in California in 2026?

Under AB 1482, the lower of 5% plus regional CPI or 10% — currently about 8% in the LA area. But if the building is under a local ordinance like the LA RSO, the local cap controls; in the City of LA that’s 3% through June 30, 2026.

How often can rent be raised in California?

For rent-controlled and AB 1482 housing, once every 12 months, with proper written notice.

How much notice does a landlord have to give?

30 days for an increase of 10% or less; 90 days for an increase over 10%.

Did Los Angeles change its rent increase rules in 2026?

Yes. Effective February 2, 2026, the RSO eliminated the extra 1% utility add-ons and the 10% additional-dependent increase, and beginning July 1, 2026 the formula drops to 90% of CPI with a 4% maximum (down from 8%).

What is the LA RSO rent increase for 2026?

3% for the period July 1, 2025 through June 30, 2026.

The Bottom Line

In California, a landlord can raise rent once a year, within a cap that depends on the building. AB 1482 sets the statewide ceiling (5% + CPI, or 10%); the LA RSO is much tighter at 3% and just lost its add-ons; unincorporated county and other cities have their own numbers. Identify the right jurisdiction, apply the correct cap, and serve proper notice — and in 2026, expect tighter limits across the board.
