Which rule applies to you

City of LA rent stabilization (RSO)

Generally rental units in the City of Los Angeles first occupied on or before October 1, 1978 — apartments, condos, townhomes, duplexes, and lots with two or more houses. A single house alone on its lot is exempt. Confirm your unit's RSO status on ZIMAS (Housing tab). RSO increases are allowed once every 12 months. Since February 2, 2026 the yearly limit is set at 90% of inflation, with a floor of 1% and a ceiling of 4% (the old range was 3%–8%). No extra percentage for landlord-paid utilities or for an added dependent. (A 10% increase per added non-dependent tenant, and LAHD-approved surcharges, are still allowed.) LAHD's web page still describes the utility change as pending final Council approval; LAHD's February 2, 2026 bulletin states it as in effect. Questions: LAHD hotline 866-557-7368.

California AB 1482 (Tenant Protection Act)

5% + regional CPI change, or 10%, whichever is lower; measured against the lowest rent charged in the prior 12 months; at most two increases in any 12-month period. For the Los Angeles–Long Beach–Anaheim area that is 8.7% for increases effective on or after August 1, 2026, and 8% for increases effective August 1, 2025 to July 31, 2026. The law runs until January 1, 2030. A brand-new tenancy can start at any rent; the cap applies to later increases.

Homes exempt from AB 1482

Certificate of occupancy issued within the previous 15 years (rolling)
Single-family home or condo that can be sold separately, if the owner is not a REIT, corporation, or LLC with a corporate member AND the tenant received the required written exemption notice (in the City of LA, condos and townhomes first occupied on or before Oct 1, 1978 are usually under the RSO instead)
Duplex where the owner has lived in the other unit since the tenancy began and still does (neither unit an ADU/JADU)
Deed-restricted or subsidized affordable housing
Dormitories owned and operated by a college, university or K-12 school
Units under a local rent control law that is stricter (e.g. City of LA RSO)

Exempt does not mean anything goes: notice rules still apply, and increases cannot be retaliatory or discriminatory.

Other cities with their own rent control

Several cities in Los Angeles and Orange counties have their own rent control laws, usually stricter than AB 1482. This calculator covers the City of Los Angeles RSO and the statewide AB 1482 cap only. Cities and areas with their own rules: Santa Monica, West Hollywood, Beverly Hills, Pasadena, Culver City, Inglewood, Pomona, Baldwin Park, Commerce, Cudahy, Gardena, Glendale, Santa Ana (Orange County), Unincorporated Los Angeles County (RSTPO) (state list).

How much notice your landlord must give

California Civil Code §827: 30 days' written notice if the increase is 10% or less; 90 days if more than 10%. The percentage counts all increases within the past 12 months, measured from the rent at any time in that period. If the notice is mailed, add 5 days (Code of Civil Procedure §1013). During a fixed-term lease, rent generally cannot rise until the lease ends unless the lease allows it.

Frequently asked questions

How much can my landlord raise rent in Los Angeles in 2026?

If your unit is under the City of LA RSO, 3% for increases effective July 1, 2026 to June 30, 2027. If it is covered by AB 1482 instead, up to 8.7% for increases effective August 1, 2026 to July 31, 2027. Exempt homes have no state percentage cap (local rent control may still apply).

How do I know if my apartment is rent stabilized (RSO)?

Look up the address on ZIMAS (zimas.lacity.org) and open the Housing tab, or call the LAHD hotline at 866-557-7368. RSO generally covers rental units in the City of Los Angeles built on or before October 1, 1978.

What is the AB 1482 rent cap for Los Angeles?

8.7% (5% plus 3.7% regional CPI) for increases effective on or after August 1, 2026. Increases effective August 1, 2025 to July 31, 2026 were capped at 8%.

Is a single-family home exempt from rent control in California?

Under AB 1482, only if the owner is not a corporation, REIT, or LLC with a corporate member, and the tenant was given the written exemption notice. Without that notice, the cap applies. In the City of Los Angeles, condos and townhomes first occupied on or before October 1, 1978 are usually under the RSO regardless; only a single house alone on its lot is exempt from the RSO.

How much notice is required for a rent increase in California?

30 days' written notice if the increase is 10% or less, and 90 days if it is more than 10% (Civil Code §827). The percentage counts every increase in the past 12 months. Add 5 days if the notice is mailed.
