The official caps this calculator uses
| Area (counties) | Increase takes effect 8/1/2025–7/31/2026 | Increase takes effect 8/1/2026–7/31/2027 |
|---|---|---|

The law sets the cap at 5% plus the regional change in the cost of living, but never more than 10% (Civil Code §1947.12). The Attorney General notes the chart is informational and the statute controls.
Before you send a notice
- Is the unit covered? Housing with a certificate of occupancy issued in the last 15 years, qualifying single-family homes and condos (with the required notice), and an owner-occupied duplex are among the exemptions. See our exemption checklist.
- Is there a local cap? Cities such as Los Angeles, Oakland, San Francisco and Santa Ana have lower caps for older buildings. The Attorney General keeps a list on the same page.
- Notice period. 30 days' written notice for an increase of 10% or less, under Civil Code §827. See rent increase notice rules.
Want this done for every unit, every year?
The California Landlord Compliance & Rent-Cap Kit tracks every increase per unit, flags the two-increases rule, helps you plan notice dates and includes a checklist of what a rent increase notice must contain.

FAQ
What is the California rent cap for 2026–2027?
For increases that take effect August 1, 2026 through July 31, 2027, the statewide cap is 8.7% in Los Angeles and Orange counties, 8.1% in Riverside and San Bernardino, 8.2% in San Diego, 8.8% in the five-county San Francisco area and 8.6% everywhere else, per the California Attorney General's chart.
What rent do I apply the percentage to?
The lowest gross monthly rent charged for the unit at any time in the 12 months before the increase takes effect. Discounts or concessions the tenant accepted are excluded from that figure (Civil Code 1947.12(a)(1)).
Can I raise the rent twice a year?
Up to two increases are allowed in a 12-month period for the same tenant, but together they cannot exceed the cap.
Does the cap apply to my single-family rental?
Often not, if the owner is not a corporation, REIT or an LLC with a corporate member, and the tenant was given the exact written exemption notice the statute requires. Without that notice the exemption does not apply.
Does a lower city cap override this?
Yes. If your city or county has a rent stabilization law that produces a lower increase, the local rule applies.
