SB 1211 for 12-unit apartment in Escondido
A 12-unit 12-unit apartment in Escondido qualifies for up to 11 new homes under SB 1211 — 8 detached ADUs and 3 interior conversions. At Escondido's median rent of $2,200/mo, that's ~$290K in additional gross annual rent.
The Escondido scenario
The scenario most Escondido 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.
Escondido watch: North County San Diego.
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.
