SB 1211 for 5-unit apartment in Pomona
A 5-unit 5-unit apartment in Pomona qualifies for up to 6 new homes under SB 1211 — 5 detached ADUs and 1 interior conversions. At Pomona's median rent of $2,100/mo, that's ~$151K in additional gross annual rent.
The Pomona scenario
The scenario most Pomona 5-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 5 detached units behind that primary structure with room for fire-access in front.
Pomona-specific note: University demand; affordable basis.
Mid-size multifamily (5–8 unit) design playbook
This is SB 1211's sweet spot. A 5-unit existing building maxes out the 8-detached cap (or comes close), so design moves are about packing detached ADUs efficiently around the existing structure and converting underutilized parking.
