AB 2221
2022 amendment that closed loopholes in AB 68 — clarified setbacks, height, and the 60-day clock.
Assembly Bill 2221 (2022) fixed several enforcement gaps in AB 68. Key updates: (1) the 60-day clock starts at first submittal — cities can no longer game the timer by issuing repeated 'incomplete' notices; (2) maximum detached-ADU height raised to 18 ft within ½ mile of transit, 25 ft for two-story ADUs on multifamily lots; (3) cities cannot deny an ADU based on nonconforming conditions of the main house; (4) explicit 4-ft side and rear setback maximum.
Together with AB 68, AB 2221 makes most LA-area lots automatically ADU-eligible.
