SB 1211 in San Diego
San Diego property owners with existing multifamily lots can now add up to 8 detached ADUs under SB 1211 — no hearings, no design review, no replacement parking. Here's what it means for property owners in San Diego County.
The San Diego angle
San Diego County stacks SB 1211 with its own ADU Bonus Program in transit areas — sometimes doubling allowable density. The play in San Diego isn't speculative — it's running the §66323 math against existing owners with surface parking they'd otherwise leave empty.
Worked example: an 8-unit building in San Diego
An 8-unit existing multifamily property in San Diego can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At San Diego's median rent of $2,300/mo, that's roughly $276K in additional gross annual rent on land you already own.
Where local ordinances conflict with §66313–66323, state law preempts.
