Under Senate Bill 9 (SB-9) Single Family zoned lots in Oakland become:
* Two-Unit residential development, and
* Parcel Subdivision resulting in Two Lots

The new State of California law (SB-9) requires the City to create a ministerial approval process for single-family residential zoned lots to 1) approve two residential units on a single-family lot and/or 2) subdivide a single-family parcel into two separate lots, enabling the creation of either a single-family home or two residential units on each resulting parcel.
How does SB-9 apply to my property?
If you own a single-family home on a lot located within single-family residential zones, the Hillside Residential Zone (RH) or Detached Unit Residential Zone (RD-1), but NOT located within the Very High Fire Hazard Severity Zone (VHFHSZ), might be eligible for:
- Two-Unit Residential Development: Two homes may be created on an eligible single-family residential parcel, whether the proposal adds up to two new residential units or adds one new unit to one existing unit.
- Single-Family Parcel Subdivision: An eligible single-family residential parcel may be split one time into two parcels of no less than 1,200 square feet. This could result in up to four units (up to two residential units on each resulting parcel) so long as certain objective standards are met and there is no unmitigable environmental impact.
Is my parcel eligible?
