SB 1211 in Fairfield
Fairfield 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 Solano County.
The Bay Area angle
High land basis but tech-driven rents make ADU pro-formas pencil quickly — payback windows of 6–9 years are common. For Fairfield owners, the calculus changed overnight: the same lot that once topped out at 2 ADUs can now host 8.
Worked example: an 8-unit building in Fairfield
An 8-unit existing multifamily property in Fairfield can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Fairfield's median rent of $2,100/mo, that's roughly $252K in additional gross annual rent on land you already own.
The arithmetic is straightforward: 8 detached + ⌊units × 25%⌋ interior, on lots zoned for the units already there.
