SB 1211 for 12-unit apartment in Redding
Redding's SB 1211 math for 12-unit apartment owners: 8 detached ADUs (the §66323 cap), plus 3 interior conversions. Total: 11 new homes. At Redding's median rent of $1,500/mo, that's ~$198K in additional gross annual rent.
The Redding scenario
Run it as a sequence: stabilize existing 12 units → permit 8 detached ADUs ministerially under §66314 → convert 3 interior spaces into rentable units → re-tenant at Redding medians.
Redding watch: North state demand; lower rents but lower costs.
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.
