What Is an SB 684 Subdivision? A Guide for Los Angeles Property Owners
Nshanyan Enterprises · October 6, 2026
If you own property in Los Angeles, you may have heard that SB 684 allows land to be divided for up to 10 homes. That headline deserves a closer look before you start planning a project.
SB 684 established a streamlined approval pathway for qualifying small housing subdivisions. It is part of California's Starter Home Revitalization Act, often called SHRA, which supports smaller-scale housing and homeownership opportunities. Eligibility depends on the property, the proposed development, and the requirements that apply when you submit. [1]
What subdivision means
A subdivision legally divides property into separate parcels or ownership interests through an approved mapping process. Under the SB 684 framework, qualifying projects can generally create up to 10 lots and 10 principal homes, with specific counting rules and exceptions. [3]
The housing can take different ownership forms, including homes on individually owned lots and qualifying condominium developments. HCD has confirmed that condominium maps can qualify when the project satisfies the other requirements. [2]
For an owner, the useful first question is: What kind of project could this property support?
How SB 1123 expanded the opportunity
SB 684's streamlining provisions began July 1, 2024. SB 1123 expanded the framework to qualifying vacant, single-family-zoned sites beginning July 1, 2025. AB 130 also made changes effective that July, including provisions concerning remainder parcels. [3]
The framework described in local guidance allows multifamily-eligible sites no larger than five acres and qualifying vacant single-family sites no larger than 1.5 acres. Other requirements still apply. [4]
What ministerial approval means
Ministerial review means the agency checks the project against applicable requirements rather than deciding whether it likes the proposal through a discretionary approval process. Qualifying maps follow a pathway without a discretionary hearing. HCD identifies a 60-day approval-or-denial period after receipt of a completed application. [5]
This does not guarantee that every proposal qualifies or that construction can begin within 60 days. Application preparation, completeness, technical review, map recordation, and building permits are separate considerations.
LA County's guidance also identifies circumstances where separate discretionary approvals, such as hillside-management or oak-tree permits, may be required before the ministerial approvals. [4]
Los Angeles City and County are different jurisdictions
Start by confirming which planning agency handles your parcel. Property within the City of Los Angeles follows the City's filing procedures. LA County Planning serves unincorporated areas outside incorporated cities. A property in another incorporated city within the county needs that city's process. [6]
A mailing address alone is not a substitute for confirming the parcel's jurisdiction. This early check helps you gather the correct forms and direct questions to the right department.
What needs checking before you proceed
Zoning, legal parcel status, size, and urban-location requirements
Existing structures, vacancy, occupancy history, and protected housing
Fire-hazard and other environmental constraints
Required density, any applicable affordability obligations, and development standards
Access, public water and sewer, and the proposed lot layout
County guidance includes urban-location and surrounding-development tests, housing protections, and public water and sewer requirements. An empty-looking yard or an unoccupied house does not establish eligibility. Evaluate the actual parcel before assuming the maximum project size is available. [4]
Important October 2026 update
New Altadena-specific legislation, SB 1090, was signed on September 30, 2026. Owners considering projects there should obtain current local confirmation of the restrictions and any exceptions before relying on earlier SHRA guidance. [7]
SB 1116 also introduces changes for applications received on or after January 1, 2027. Those upcoming standards should not be treated as the rules already governing an October 2026 application. Application timing matters. [8]
How to take the first step
Before commissioning a detailed design, assemble a basic property file: the address, assessor's parcel number, available surveys or plans, permit records, and information about existing buildings and occupancy.
Then identify the questions that need answers. Which agency will review the project? What technical information is missing? Which licensed professionals need to participate? What should happen before an application is prepared?
