California’s Senate Bill 9 opens up new possibilities for homeowners to do more with their existing property whether that means adding additional units, creating flexible living spaces, or exploring new income opportunities. At Urbatect, we specialize in navigating the complexities of SB 9 to help you split your lot or build on a single-family property.
From evaluating your property’s eligibility to handling design, permits, and construction, having a clear path forward makes all the difference in turning potential into a real, valuable outcome.
What is SB 9? And Does Your Property Qualify?
Signed into law to address California’s housing shortage, SB 9 allows eligible homeowners in single-family zones to unlock new development opportunities on their existing property.
- Urban Lot Splits — Divide one residential lot into two separate parcels, subject to eligibility and owner-occupancy requirements.
- Two-Unit Developments — Build up to two primary homes on a single lot, either attached or detached.
- Expanded Potential — Qualifying properties may support up to four total housing units where only one was previously allowed.
All SB 9 projects are reviewed ministerially, meaning a faster, more predictable approval process when requirements are met.
Does Your Property Qualify?
Your property may be eligible for SB 9 if it meets some of the following criteria:
- Located in a single-family residential zone
- Situated within an urbanized or developed area
- Meets minimum lot size and access requirements
- No recent tenant displacement from the property
- Not located in environmentally restricted or historic zones
- Able to comply with local development standards and setbacks
