California requires 30 days notice for rent increases of 10% or less and 90 days notice for increases above 10%. AB 1482 caps annual increases at the lower of 5% + local CPI or 10% flat, with exemptions for natural-person single-family owners and buildings under 15 years old.
- ·Local rent-stabilized cities (San Francisco, Los Angeles, Oakland, Berkeley, West Hollywood) have stricter caps that override AB 1482
- ·AB 414 (2023) renumbered the small-owner carve-out from 1950.5(c)(4)(A) to (c)(5)(A) and extended it to LLCs with all natural-person members
- ·Single-family homes or condos owned by a natural person (or LLC whose members are all natural persons post-AB 414), with written notice to tenant
- ·Buildings with certificate of occupancy issued within the last 15 years (rolling exemption)
- ·Deed-restricted affordable housing
- ·Hotels and tourist accommodations
- ·Some owner-occupied duplexes
What this calculator is, and what it is not.
This calculator applies the California rules as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled cities) can apply stricter rules. For contested cases, consult a California-licensed attorney.
