How much notice is required
For week-to-week, month-to-month and other periodic tenancies, written notice must be delivered personally or by mail: 30 days for increases of 10% or less in 12 months, 90 days for more. If mailed, add 5 calendar days within California (10 if mailed from or to another state). (Civ. Code § 827(b); Code Civ. Proc. § 1013(a))

| Month-to-month or other periodic tenancy | increase over 10% | 90 days |
- The notice must be in writing.
- Mailed notice: add 5 days.
Example: a notice handed over on November 2, 2026 in California
Earliest date the new rent can start, with rent due on the 1st, worked out from the California rule above:
- For a month-to-month tenant of 1 year raising rent 5% or a week-to-week tenant raising rent 5%: Wednesday, December 2, 2026
- For a month-to-month tenant of 3 years raising rent 12%: Sunday, January 31, 2027
Is there a limit on how much rent can go up?
The Tenant Protection Act cap applies to covered units after the initial rent of a tenancy is set. CPI is the April-to-April change for the metro area (or the California CPI elsewhere). The section is repealed on January 1, 2030. (Civ. Code § 1947.12)
- Formula:
- 5% plus the regional CPI change, or 10%, whichever is lower, of the lowest rent in the prior 12 months
- 2026 maximum:
- 8.7% (CA Attorney General – Los Angeles & Orange counties, increases starting 8/1/2026–7/31/2027)
- 2026 maximum:
- 8.1% (CA Attorney General – Riverside & San Bernardino counties, 8/1/2026–7/31/2027)
- 2026 maximum:
- 8.2% (CA Attorney General – San Diego County, 8/1/2026–7/31/2027)
- 2026 maximum:
- 8.8% (CA Attorney General – Alameda, Contra Costa, Marin, San Francisco, San Mateo counties, 8/1/2026–7/31/2027)
- 2026 maximum:
- 8.6% (CA Attorney General – all other counties, 8/1/2026–7/31/2027)
- Not covered:
- Units with a certificate of occupancy in the last 15 years; single-family homes/condos not owned by a REIT, corporation or LLC with a corporate member, if the tenant got the required written exemption notice; owner-occupied duplex; deed-restricted affordable housing; dorms; units under stricter local rent control
- How often:
- No more than two increases in any 12-month period (total still within the cap)
Raising rent during a lease
In a fixed-term lease the landlord cannot raise rent during the term unless the lease permits it; rent may be increased on renewal. (CA Dept. of Real Estate, California Tenants guide (2026))
City and county rent control
Cities and counties may adopt rent control, but the Costa-Hawkins Act exempts units with a certificate of occupancy after Feb. 1, 1995 and separately alienable units (single-family homes, condos) and allows vacancy decontrol. (Civ. Code §§ 1954.50–1954.535 (§ 1954.52))
- Los Angeles (city): Rent Stabilization Ordinance covers most rentals built on or before Oct. 1, 1978; rent may rise once every 12 months by the yearly allowable percentage. From Feb. 2, 2026 the extra utility percentage is no longer allowed.
- San Francisco: Rent Ordinance limits yearly increases for covered units to the Rent Board's annual allowable amount; AB 1482 applies only to units outside the Rent Ordinance limits.
- Oakland: Rent Adjustment Program limits increases for covered units and handles petitions.
- Berkeley: Rent Stabilization Board sets annual general adjustments for covered units.
- Sacramento (city): Tenant Protection Program: maximum 8.6% from July 1, 2026 (5% + 3.6% California CPI), once every 12 months.
Retaliatory rent increases
A landlord may not increase rent within 180 days after a tenant in good faith complains about habitability to the landlord or an agency, or after related inspections or court proceedings, if the tenant is not behind on rent; a tenant can use this protection once in any 12-month period. Separately, at any time (no 180-day limit), a landlord may not raise rent to retaliate because the tenant lawfully organized or joined a tenants' association or lawfully exercised any legal right; the tenant must produce evidence the increase was retaliatory. (Civ. Code § 1942.5(a), (d))
Also good to know
- AB 1157 (2025–26), which would have lowered the cap, died in the Assembly Judiciary Committee in January 2026.
- Longer notice periods in other laws, regulatory agreements or contracts (e.g., subsidized housing) control (Civ. Code § 827(c)).
- Increases from income recertification in subsidized housing need only 30 days' notice (Civ. Code § 827(b)(3)(B)).
