Two-Unit Residential Development and Parcel Subdivision Resu

SB-9-New-Housing-Options-Large.png
A 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.

 

Before You Start

Please review the Permit Requirements below as these vary from project to project.

Ready to get started? First, make sure you are registered and activated at our Online Permit Center. For instructions, please visit our Planning & Building Video Tutorials webpage.

Download the Planning Application For Ministerial Approval of Two-Unit Residential Development or Parcel Subdivision Resulting in Two Lots With Residential Units On Each Lot (SB-9) and follow the steps as outlined below.

 

What Can I Do?

If you own a single-family home on a lot located within a single-family residential zone - the Hillside Residential Zone (RH), 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?

  • An application form below includes a zoning criteria checklist to establish eligibility of a single-family residential zoned parcel. Please review it carefully for details not listed here.
  • Only parcels that are zoned single-family residential in the RH zone and not within the Very High Fire Hazard Severity Zone (VHFHSZ) may be considered. Please check this online Zoning Map to see if your parcel is within the single-family residential zones and outside of the VHFHSZ. However, location alone does not establish eligibility.
  • Other factors including a parcel's location in environmentally sensitive or hazardous areas or location within a historic district may affect eligibility. Please review the application zoning criteria checklist for full details by following the link below.
  • Planning/Zoning requirements are based on objective standards and do not require the Regular Design Review process.

 

Who Can Be Issued a Permit?

  • Owners of an eligible Single-Family parcel or their legal representative.
