SB9 LOT SPLIT STEPS

Introduction:

The California Senate Bill 9 (SB 9) allows property owners to split a single-family residential lot into two separate lots and/or build additional housing units. The following are the key steps to legally subdivide a lot under SB 9 in Los Angeles:

Step 1: Confirm Eligibility

• The property must be in a single-family residential (R1) zone or an equivalent low-density zone.

• The lot must not be in an environmental hazard zone, flood zone, historic district, or protected wildlife corridor.

• The owner must occupy one of the units as a primary residence for at least 3 years after the lot split.

Step 2: Conduct Feasibility Analysis

• Lot Size Requirements: The original lot must be at least 2,400 square feet.

• Subdivision Limitations: Each new lot must be at least 1,200 square feet and must be approximately equal in size (no lot can be smaller than 40% of the original size).

• Utility Access: Check access to water, sewer, and electricity.

• Setback Compliance: Ensure the new structures will comply with 4-foot rear and side setbacks.

• Parking: At least one parking space per unit is required unless the lot is within ½ mile of public transit.

Step 3: Hire Professionals

  • Tree Arborist: To verify tree conservation
