SB 1211 for 12-unit apartment in Pomona
A 12-unit 12-unit apartment in Pomona qualifies for up to 11 new homes under SB 1211 — 8 detached ADUs and 3 interior conversions. At Pomona's median rent of $2,100/mo, that's ~$277K in additional gross annual rent.
The Pomona scenario
The scenario most Pomona 12-unit apartment owners face: an existing building, mature trees, and a back lot that's currently doing nothing. SB 1211's 4-ft setback and 18-ft height envelope fits 8 detached units behind that primary structure with room for fire-access in front.
Pomona-specific note: University demand; affordable basis.
Large multifamily (10+ unit) design playbook
A 12-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 3 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
