SB 1211 for Duplex in Fresno
Own a duplex in Fresno? SB 1211 lets you stack 3 new units on top of your existing 2: 2 detached + 1 interior. At Fresno's median rent of $1,500/mo, that's ~$54K in additional gross annual rent.
The Fresno scenario
Picture the typical case: a 2-unit duplex on a Fresno block built between 1955 and 1975, with surface parking that hasn't been fully utilized in years. SB 1211 turns that parking into 2 detached units plus 1 interior conversion — 3 new doors that didn't exist before 2024.
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 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.
