How much can your rent go up?
Los Angeles has three separate rent-increase rules. Pick where your unit is to estimate the maximum legal 2026 increase, plus the notice your landlord must give.
An LA mailing address doesn’t mean your unit is in the City of Los Angeles or under the RSO. Check your address’s Housing tab in ZIMAS, or read our ZIMAS · rent-control guide.
Enter your current monthly rent (a number above $0) to see a result.
/mo (+%)
+/mo increase
For increases that took effect before February 2, 2026, the pre-2026 RSO rules applied (including possible gas/electricity add-ons). Check LAHD for those.
The official rate for increases taking effect on this date isn’t published yet, or the date is outside the periods this tool covers. Check the official source.
Official source →Exempt units
If your unit is exempt (for example, a certificate of occupancy issued within the last 15 years, or a single-family home or condo owned by an individual who gave you the required exemption notice), no state or local percentage cap applies. The notice rules below still apply.

Check which rule applies before relying on a number. City of LA: the Housing tab for your address in ZIMAS shows RSO status. Unincorporated county areas: check DCBA. Other cities in LA County (Santa Monica, West Hollywood, Beverly Hills, Pasadena and others) have their own rules.

Frequently asked questions
How much can my landlord raise my rent in Los Angeles in 2026?
It depends which rule covers your unit. City of LA RSO units: 3% for increases taking effect July 1, 2025 – June 30, 2027 (LAHD), with no extra gas or electricity add-ons since February 2, 2026. Unincorporated LA County (RSTPO): 1.919% for most units, July 1, 2026 – June 30, 2027. Otherwise statewide AB 1482 usually caps increases at 8.7% for increases taking effect August 1, 2026 – July 31, 2027 (8% before August 1, 2026), unless the unit is exempt.
How much notice must my landlord give before a rent increase?
Under California Civil Code §827, 30 days if the cumulative increase over 12 months is 10% or less, and 90 days if it is more than 10%. Add 5 days if it is served by mail.
How do I know which rule applies to my apartment?
First find whether your address is in the City of Los Angeles, an unincorporated county area, or another city — an LA mailing address alone doesn’t tell you. In the City, most rentals first built on or before October 1, 1978 are under the RSO (ZIMAS shows this on the Housing tab). Unincorporated areas use the county RSTPO. Otherwise AB 1482 usually applies, unless the unit is exempt.
