SB 1211 for 8-unit apartment in Santa Ana
Santa Ana's SB 1211 math for 8-unit apartment owners: 8 detached ADUs (the §66323 cap), plus 2 interior conversions. Total: 10 new homes. At Santa Ana's median rent of $2,400/mo, that's ~$288K in additional gross annual rent.
The Santa Ana scenario
Run it as a sequence: stabilize existing 8 units → permit 8 detached ADUs ministerially under §66314 → convert 2 interior spaces into rentable units → re-tenant at Santa Ana medians.
Local tip for Santa Ana: Dense lots; surface parking conversions are the play.
Mid-size multifamily (5–8 unit) design playbook
This is SB 1211's sweet spot. A 8-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.
