Townhome builders in California could face fewer local hurdles
Under AB 1751, qualifying projects would move through a streamlined process without a hearing or discretionary review. The bill defines the homes tightly and leaves local agencies a safety valve for documented public-health risks.
The state bill is aimed at a narrow part of the housing market: single-family townhomes. Assemblymember Sharon Quirk-Silva’s measure would make it easier for developers to move qualifying projects forward, while still preserving local authority to reject a project with an unfixable adverse impact.
- Townhomes would get a clearer approval path under AB 1751.
- Local agencies would have to review qualifying maps ministerially, without a hearing.
- The bill defines townhomes as single-family units up to three stories tall.
- Cities could still block a project for a specific, unfixable public-safety impact.
- In California, AB 1751 is aimed at the awkward space between the single-family house and the bigger apartment project
In California, AB 1751 is aimed at the awkward space between the single-family house and the bigger apartment project. Assemblymember Sharon Quirk-Silva’s Missing Middle Townhome Ownership Act would give townhome development a more usable place in state housing law, so buyers and builders are not squeezed between rules built for very different kinds of homes.
The bill would add Section 65852.29 and a new chapter to the Subdivision Map Act, the state law that governs how local agencies handle subdivision maps. It is a targeted change, not a rewrite of housing law, but it could matter where local review has made this kind of home hard to deliver.
A narrower lane through local review
The bill builds on California’s existing system for some qualified housing developments, which already get streamlined, ministerial review instead of a discretionary process. AB 1751 would extend that idea to townhome housing development projects that meet the bill’s planning standards and procedural requirements.
For qualifying projects, local agencies would have to ministerially consider a parcel map, or a tentative and final map, without a hearing or discretionary review. The newly created parcels would have to be at least 600 square feet, and the subdivision would still have to satisfy the other density and site rules in the measure.
The definition does the work
The bill defines a townhome as a single-family dwelling unit of three stories or fewer that shares a common wall with neighboring units, or is separated from them by an air gap. A townhome development project would be one made entirely of units that fit that definition.
That definition matters because it draws a line around the homes the bill is trying to help. The point is to make ownership housing in the middle of the market easier to build without collapsing it into either detached-home rules or the full weight of larger multifamily development.
The safety valve stays open
AB 1751 would still let a local agency deny a project if it makes written findings, based on the preponderance of the evidence, that the project would create a specific adverse impact on public health and safety that cannot be feasibly mitigated. So the bill opens a faster lane, but not a blank check.
That is the balance at the center of the proposal: less local discretion where the project fits the state’s rules, but room to stop a project when the harm is concrete and documented.
