Process to Apply through CA SB 9

California Senate Bill 9, effective January 1, 2022, applies in single family residential zoning districts (RR, R1, Single-Family Planned Developments). This bill requires the ministerial approval of two residential units per lot (referred to as Two Unit Developments) and parcel maps for an two lot subdivision (referred to as an Urban Lot Split). 

Step 1: CONFIRM THE PROJECT IS ELIGIBLE

Projects for a Two-Unit Development and/or an Urban Lot Split must meet all the criteria on the respective Senate Bill 9 (SB 9) Eligibility Checklist to qualify for ministerial review. A project that includes a proposal for a Two-Unit Development and an Urban Lot Split must complete both checklists.

Step 2: SUBMIT A COMPLETE SB 9 APPLICATION PACKET

If you determine your project is eligible, you may submit the SB 9 Two-Unit Development application, and/or the Urban Lot Split Application Packet with each of the required forms, information, and plans required for City staff to review your project. Each of the listed items is required for a complete application.

Step 3: TIMELINES FOR MINISTERIAL REVIEW 

1. Completeness & Eligibility Review. The City will issue a determination of completeness and eligibility.

2. Action on the Application. City staff will issue an approval or denial on the application following the completeness determination.

Step 4: SUBMIT FOR BUILDING AND/OR ENGINEERING APPROVALS  

Following a project approval, permits including Building Permits and Encroachment Permits are applied for and reviewed.
