SB 1211 for 6-unit apartment in Santa Clara
A 6-unit 6-unit apartment in Santa Clara qualifies for up to 7 new homes under SB 1211 — 6 detached ADUs and 1 interior conversions. At Santa Clara's median rent of $2,900/mo, that's ~$244K in additional gross annual rent.
The Santa Clara scenario
The scenario most Santa Clara 6-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 6 detached units behind that primary structure with room for fire-access in front.
Santa Clara watch: Tech demand driver.
Mid-size multifamily (5–8 unit) design playbook
This is SB 1211's sweet spot. A 6-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.
