SB9 lot split allows homeowners in Los Angeles to divide a single-family property into two separate parcels. This law creates new development opportunities without going through complex rezoning processes.
However, strict requirements must be followed to qualify for an SB9 lot split. Understanding these rules helps you avoid delays and make better decisions before starting the process.
What is SB9 Lot Split in Los Angeles?
SB9 lot split is a California law that allows property owners to split one residential lot into two. It applies only to single-family zoned properties and aims to increase housing supply.
In Los Angeles, this means you can create two legal lots and potentially build multiple units. This process is designed to be simpler than traditional subdivision but still requires meeting specific city and state regulations.
SB9 Lot Split Requirements in Los Angeles
SB9 lot split requirements in Los Angeles are based on zoning, lot size, ownership, and development rules. Each condition must be met to get approval from the city. These requirements ensure that new developments follow local planning standards and maintain neighborhood balance.
Eligible Zoning Requirements
The property must be located in a single-family residential zone such as R1 or similar classifications. Multifamily or commercial zones do not qualify under SB9. The zoning must allow residential use and meet local planning guidelines.
Minimum Lot Size Requirements
Each newly created lot must be at least 1,200 square feet in size. The original lot should also be large enough to allow a proper split while meeting this minimum requirement. Smaller lots may not qualify for subdivision under SB9 rules.
Lot Split Ratio Rules (40/60 Rule)
The lot split must follow a proportional division, typically around a 40/60 ratio. Each new parcel must be at least 40% of the original lot size. This rule ensures that both lots remain usable and meet development standards.
Maximum Number of Lots Allowed
SB9 allows only one split, which means a single property can be divided into two lots. Further subdivision beyond this is not permitted under this law. This keeps development controlled and prevents overuse of land.
Owner Occupancy Requirement
In most cases, the property owner must agree to live in one of the units for at least three years. This requirement helps prevent large-scale investor-driven development. It ensures that the property remains primarily owner-occupied.
Restrictions and Limitations
Certain properties may not qualify due to environmental or legal restrictions. These include historic districts, high fire zones, or properties with protected housing status. Additional local regulations may also apply depending on the location within Los Angeles.
SB9 Eligibility Checklist (Quick Qualification Guide)
Use this checklist to quickly determine if your property qualifies for an SB9 lot split:
- Property is located in a single-family residential zone
- Lot is large enough to create two parcels of at least 1,200 sq ft each
- Each new lot meets the 40% minimum size requirement
- Only one split is planned (no further subdivision)
- Owner agrees to occupy one unit for at least three years
- Property is not located in restricted or protected zones
- No major legal or environmental limitations apply
What Can You Build After an SB9 Lot Split?
After an SB9 lot split, you can develop each parcel with up to two residential units. This means a single property can support a total of four units across both lots. Homeowners often build a duplex on each lot or combine a primary home with an accessory dwelling unit.
The final development depends on local zoning standards, setbacks, and design rules in Los Angeles. This flexibility makes SB9 a strong option for increasing property value and generating rental income.

- Miscalculating the 40/60 lot split ratio
