SB 1211 for Duplex in Anaheim
Anaheim's SB 1211 math for duplex owners: 2 detached ADUs (the §66323 cap), plus 1 interior conversions. Total: 3 new homes. At Anaheim's median rent of $2,400/mo, that's ~$86K in additional gross annual rent.
The Anaheim scenario
Run it as a sequence: stabilize existing 2 units → permit 2 detached ADUs ministerially under §66314 → convert 1 interior space into rentable units → re-tenant at Anaheim medians.
Local tip for Anaheim: OC jurisdictions vary widely in ADU treatment.
Small multifamily (2–4 unit) design playbook
Small multifamily lots are usually constrained on width before they're constrained on count. With a 2-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.
