What is SB9?

August 28, 2025

SB9 (Senate Bill 9), also known as the California Housing Opportunity and More Efficiency (HOME) Act, became law on January 1, 2022. It was created to help address California’s housing shortage by making it easier for homeowners to add housing units on single-family lots.

What SB9 Does:

  1. Lot Splits (Urban Lot Split Provision)

    • Allows eligible single-family property owners to split their lot into two parcels (as small as 1,200 sq. ft. each).

    • Each lot can then have its own housing units built on it.

  2. Two Homes per Lot

    • Each new parcel can have up to two residential units.

    • Combined with a lot split, that means up to 4 homes (2 main house + 2 ADUs) can replace a single-family house.
