SB 1211 for Triplex in Stockton
Own a triplex in Stockton? SB 1211 lets you stack 4 new units on top of your existing 3: 3 detached + 1 interior. At Stockton's median rent of $1,600/mo, that's ~$77K in additional gross annual rent.
The Stockton scenario
Picture the typical case: a 3-unit triplex on a Stockton block built between 1955 and 1975, with surface parking that hasn't been fully utilized in years. SB 1211 turns that parking into 3 detached units plus 1 interior conversion — 4 new doors that didn't exist before 2024.
Stockton-specific note: Lower cost basis; commuter market for Bay Area.
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.
