SB 1211 in Modesto
Senate Bill 1211 (Skinner, 2024) lets owners of existing multifamily lots in Modesto build up to 8 detached ADUs — without replacement parking, without discretionary review. Here's what it means for property owners in Stanislaus County.
The Central Valley angle
Lower-rent markets with the best permit timelines in the state. Margins are tight but volume is achievable. Modesto's SB 1211 opportunity sits in the gap between what zoning historically allowed and what state law now requires cities to permit ministerially.
Worked example: an 8-unit building in Modesto
An 8-unit existing multifamily property in Modesto can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Modesto's median rent of $1,500/mo, that's roughly $180K in additional gross annual rent on land you already own.
Cities can't require less than SB 1211 allows; they can permit more. Several already do.
Modesto jurisdiction notes

Frequently asked questions about SB 1211 in Modesto
Does SB 1211 apply to my Modesto property?
If your lot in Modesto (Stanislaus County) currently has 2 or more legal residential units, yes — SB 1211 applies as state law and supersedes local ordinances that conflict with §66314. Single-family lots use SB 9 instead.
How long do permits take in Modesto?

What's a Modesto multifamily ADU actually worth?
At Modesto's median 1BR rent of $1,500/month, an 8-detached-ADU project produces roughly $144K in additional gross annual rent — before counting interior conversions.
Can Modesto require parking replacement?
No. §66313 prohibits cities — including Modesto — from requiring 1:1 replacement of any parking spaces removed to build SB 1211 ADUs.
Are there Stanislaus County overlays I need to worry about?
Possibly. Coastal-zone parcels, historic districts, and very-high fire-severity zones still trigger objective-standards review. But subjective design or neighborhood-character review is preempted.
