California’s SB9 legislation allows eligible property owners to split single-family lots and build additional units. This law opens new opportunities for homeowners, developers, and investors in Los Angeles to maximize their property’s potential while staying compliant with zoning regulations.
The SB9 Lot-Split Potential Calculator is a simple tool designed to estimate how many units you can build on your property under SB9 rules. By entering basic details such as lot size, zoning type, existing units, and lot dimensions, the calculator provides a realistic estimate of potential additional units.
SB9 Lot-Split Eligibility Table
| Parameter | Requirement / Threshold | Notes / Impact on Eligibility |
|---|---|---|
| Lot Size | ≥ 5,000 sq ft | Eligible for splitting into 2 units |
| Zoning Type | R1, R2, R3 | Determines maximum units allowed |
| Existing Units | Any current units on lot | Subtracts from potential additional units |
| Lot Width | ≥ 40 ft (recommended) | Lots narrower than this may not qualify fully |
| Lot Depth | ≥ 60 ft (recommended) | Minimum depth required for compliance |
| Maximum Units | 2 per lot under SB9 | Cannot exceed this even if lot is larger |
| Additional Considerations | Local planning restrictions, setbacks, utility access | May further impact eligibility and design possibilities |
