Two-Unit Development (TUD)
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.
Urban Lot Splits (ULS)
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.
Development Standards and Requirements
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 to the left 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.
