Senate Bill 9 (SB 9), the California Housing Opportunity and More Efficiency (HOME) Act, is a California state law that aims to alleviate the housing crisis facing cities across California by providing new ways to increase housing supply and diversify the types of housing available.
Key Components of SB 9
Urban Lot Split
Provides a streamlined process for subdividing an existing single-family zoned lot into two new parcels, also known as an Urban Lot Split
Two Unit Developments
Provides a streamlined process for creating Two Unit Developments on single-family zoned lots
Both of the above streamlined processes are subject to specific eligibility criteria. The best way to assess whether a parcel is eligible for SB 9 is to use City Planning's Zone Information and Map Access System (ZIMAS) tool. Enter the address in the pop-up window, click the "Planning and Zoning" menu on the left side of the screen, and scroll down to the "SB 9 Eligibility" line. Click the adjacent link to display the Eligibility Criteria Checklist, which will indicate whether the site is eligible for SB 9.
NOTE: Two Unit Developments are processed by the Los Angeles Department of Building and Safety (LADBS) through a building permit application, while Urban Lot Split applications are processed by City Planning.
