SB 1211 for 16-unit apartment in Palmdale
A 16-unit 16-unit apartment in Palmdale qualifies for up to 12 new homes under SB 1211 — 8 detached ADUs and 4 interior conversions. At Palmdale's median rent of $1,700/mo, that's ~$245K in additional gross annual rent.
The Palmdale scenario
The scenario most Palmdale 16-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.

Large multifamily (10+ unit) design playbook
A 16-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 4 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
