SB 1211 for Fourplex / 4-unit in Fresno
A 4-unit fourplex / 4-unit in Fresno qualifies for up to 5 new homes under SB 1211 — 4 detached ADUs and 1 interior conversions. At Fresno's median rent of $1,500/mo, that's ~$90K in additional gross annual rent.
The Fresno scenario
The scenario most Fresno fourplex / 4-unit 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 4 detached units behind that primary structure with room for fire-access in front.
Local tip for Fresno: Lower cost basis; rents lower but margins still attractive.
Small multifamily (2–4 unit) design playbook
Small multifamily lots are usually constrained on width before they're constrained on count. With a 4-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.
