The Oxnard scenario
Picture the typical case: a 20-unit 20-unit apartment on a Oxnard block built between 1955 and 1975, with surface parking that hasn't been fully utilized in years. SB 1211 turns that parking into 8 detached units plus 5 interior conversions — 13 new doors that didn't exist before 2024.
Local tip for Oxnard: Coastal regulation on lots within zone.
Large multifamily (10+ unit) design playbook
A 20-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 5 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
