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?

• Only parcels that are zoned single-family residential and not within the Very High Fire Hazard Severity Zone (VHFHSZ) may be considered.
• 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
• A FREE Development Potential report will show you if your lot is eligible for SB-9

How to apply for permits under SB-9?

STEP ONE: Homeowners start with a Feasibility Study. Feasibility studies help you figure out if a project SB9 is the right thing to do to reach your goals. This is what you need to do before paying a lot of money and wasting time:

1. Check if your property is located in one of the qualified zones by searching your address here
2. Understand the type of development you could build on your property considering your lot size and the existing building(s). Being allowed to build per zoning and have enough room to add building area on your lot, are two different things.
3. Choose the location of the new building(s) for each development option;
4. Check if the calculated size of the new building(s) is enough for you to:
   • get the ROI from renting or sale it
   • host family and friends
   • afford to build
   • give you the market value to cover the construction cost

Once you have all these figured out, it's time to look for a team to help you complete the project. Going through these 5 Steps before deciding to move on with your project, it'll help you have a focused conversation with an architect, contractor and with your lender. Choosing a realistic path, it'll make you and your team have a positive experience going through this project.
