SB 1211 for 10-unit apartment in Sacramento
Own a 10-unit apartment in Sacramento? SB 1211 lets you stack 10 new units on top of your existing 10: 8 detached + 2 interior. At Sacramento's median rent of $1,900/mo, that's ~$228K in additional gross annual rent.
The Sacramento scenario
Picture the typical case: a 10-unit 10-unit apartment on a Sacramento 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 2 interior conversions — 10 new doors that didn't exist before 2024.
Sacramento-specific note: Sacramento has a fast-track ADU permit pathway.
Large multifamily (10+ unit) design playbook
A 10-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 2 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
