Last updated: Verified:
Comprehensive guide to California zoning laws, building codes, and ADU regulations across major cities.
Key Facts
- Building Code: 2022 California Building Code (based on 2021 IBC)
- State ADU Law: Yes — ADU-friendly
- ADU Details: California has enacted multiple landmark ADU laws including AB 68, SB 13, AB 881, and AB 2221. These laws significantly reduce local barriers to ADU construction by limiting fees, streamlining permit review to 60 days, removing owner-occupancy requirements, prohibiting parking requirements near transit, and allowing both attached and detached ADUs plus junior ADUs (JADUs) on most residentially zoned lots statewide.
