SB 1211 in Simi Valley
Senate Bill 1211 (Skinner, 2024) lets owners of existing multifamily lots in Simi Valley build up to 8 detached ADUs — without replacement parking, without discretionary review. Here's what it means for property owners in Ventura County.
The Central Coast angle
Coastal Commission overlays apply to some parcels. Where they don't, scarcity makes rent upside extreme. For Simi Valley 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 Simi Valley
An 8-unit existing multifamily property in Simi Valley can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Simi Valley's median rent of $2,400/mo, that's roughly $288K 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.
