The California rule underneath

| Rent cap right now | 8.7% for increases taking effect August 1, 2026 through July 31, 2027 (5% plus 3.7% inflation) Applies: Covered units only. Inflation is the BLS consumer price index for the Los Angeles-Long Beach-Anaheim area, April to April, as the statute requires; the figure is recomputed every year. |

| Rent cap — new construction exemption | Housing with a certificate of occupancy issued within the previous 15 years is exempt (rolling) Applies: Mobilehomes excepted. |
| Rent cap — single-family home or condo exemption | A home or condo that can be sold on its own is exempt when the owner is not a REIT, a corporation or an LLC with a corporate member, and the tenant was given the written exemption notice Applies: The same exemption applies to the just-cause rule (§ 1946.2(e)(8)). |
| Rent cap — owner-occupied duplex exemption | A duplex in one building is exempt when the owner lived in the other unit at the start of the tenancy and still does, unless either unit is an ADU or JADU |
