SB 1211 for Triplex in Redding
Redding's SB 1211 math for triplex owners: 3 detached ADUs (the §66323 cap), plus 1 interior conversions. Total: 4 new homes. At Redding's median rent of $1,500/mo, that's ~$72K in additional gross annual rent.
The Redding scenario
Run it as a sequence: stabilize existing 3 units → permit 3 detached ADUs ministerially under §66314 → convert 1 interior space into rentable units → re-tenant at Redding medians.
Redding-specific note: North state demand; lower rents but lower costs.
Small multifamily (2–4 unit) design playbook
Small multifamily lots are usually constrained on width before they're constrained on count. With a 3-unit existing footprint, the binding constraint becomes side-yard setbacks (4 ft min) and the 18-ft height limit. Two-story stacked-flat ADUs over surface parking are the highest-yield typology.
