Separately, the statewide Tenant Protection Act caps annual increases on covered units at 5% plus local CPI or 10%, whichever is lower, with at most two increases per year. Many single-family homes and newer buildings are exempt from the cap (but never from the notice rules), and cities with stricter local rent control keep their own limits.

California rent increase notice at a glance

Notice — month-to-month 30 days
Varies by increase size

The notice period depends on the size of the increase. An increase that, combined with all increases in the prior 12 months, totals 10% or less takes 30 days' written notice; a cumulative 12-month increase above 10% takes 90 days' written notice. An increase caused by a change in the tenant's income or family composition found in a recertification required by statute or regulation takes 30 days' notice whatever its size, and a longer notice period set by another statute, a regulation, a recorded regulatory agreement or a contract controls.

Add 5 calendar days if the notice is mailed within California, or 10 if it is mailed from elsewhere in the United States (CCP § 1013(a)).

Fixed-term leases Rent may not be increased during a fixed term unless the lease provides for it. The §827 notice mechanics govern month-to-month changes.
Statewide rent control / stabilization Yes
Rent control details

California has a statewide rent cap. The Tenant Protection Act (AB 1482) limits annual increases on covered units to the lesser of 5% plus regional CPI or 10%, with at most two increases per 12 months. Many units are exempt, and stricter local rent-control ordinances control where they exist.

The cap is codified at Civ. Code § 1947.12. It is measured against the lowest gross rent charged in the prior 12 months, and rent discounts, incentives, concessions or credits the owner offered and the tenant accepted are left out of that figure, so the cap is worked out from the undiscounted rent. The gross monthly rate and any owner-offered discounts, incentives, concessions or credits must be listed and identified separately in the lease or rental agreement, or in any amendment to an existing one. The cap remains in effect until January 1, 2030, when the section is repealed.

Exempt: housing with a certificate of occupancy issued within the previous 15 years (a rolling window), unless it is a mobilehome; single-family homes, condos and other units that can be sold separately, where the owner is not a REIT, a corporation, an LLC with a corporate member or mobilehome park management, and the tenants have been given the statutory written exemption notice; a duplex where the owner lived in one unit at the start of the tenancy and still does, and neither unit is an accessory or junior accessory dwelling unit; deed-restricted or subsidized affordable housing; school and college dormitories; and housing under a local rent-control law that limits annual increases to less than the state cap.

Local rent regulation California cities and counties may adopt rent control, and many have, but state law limits how far local rules can reach — the Costa-Hawkins Act exempts newer buildings and single-family homes and lets landlords reset rent between tenancies, while a separate statewide cap of 5% plus inflation (max 10%) covers most other rentals through 2029 (Cal. Civ. Code §§ 1954.50–1954.535, 1947.12).
Frequency limits No more than two increases in any 12-month period on AB 1482-covered units.
