Senate Bill 9 (SB 9) is a California state law which took effect on January 1, 2022. The bill adds two sections to the Government Code Sections 65852.21 and 66411.7, and amends provisions of the State Subdivision Map Act (Section 66452.6).
SB 9 allows for two dwelling units on a single family zoned lot, subject to eligibility criteria and certain development standards. The dwelling units may be detached or attached. Permit applications TUDs may be submitted to LADBS for plan check and permitting.
SB 9 allows an existing single family zoned parcel to be subdivided into two parcels, subject to eligibility criteria and certain development standards. A project may combine a ULS with a TUD with certain limitations. ULS applications may be filed with City Planning for review and processing.
An SB 9 project is subject to eligibility criteria and certain development standards as detailed in the State Bill and summarized in the Inter-Departmental Memo, both of which can be found at the links on the menu at the top of this page. An SB 9 Eligibility Checklist can be found on ZIMAS by searching the project address, expanding the "Planning and Zoning" section on the left side menu, and clicking on "view" next to "SB 9 Eligibility".
Objective zoning, subdivision or design review standards that would have the effect of physically precluding the construction of two dwelling units of 800 square feet in floor area each or an Urban Lot Split, may not be imposed. Deviations will be reviewed by Los Angeles Department of City Planning.
All other standards such as the City of Los Angeles Building and Residential Codes must be fully complied with.
