LA County Supervisor District 4: Communities, Supervisor, and Services
LA County's Fourth Supervisorial District covers a large swath of the county's western and central areas, encompassing incorporated cities, unincorporated communities, and distinct neighborhoods that together serve a population in the millions. The Los Angeles County Board of Supervisors governs the county through 5 districts, each electing one supervisor to a four-year term. Understanding District 4's geographic scope, the supervisor's institutional role, and the county services delivered within its boundaries helps residents navigate everything from public health programs to land use decisions.
Definition and scope
LA County Supervisor District 4 spans a population of roughly 2 million residents, consistent with the Board of Supervisors' constitutional mandate under California Government Code § 25000 et seq. to divide the county into 5 districts of approximately equal population. The district's boundaries are redrawn every 10 years following the federal decennial census, with the most recent redistricting completed in 2021 by the LA County Redistricting Commission.
District 4 includes cities such as West Hollywood, Beverly Hills (which contracts for certain county services despite being an independent city), Culver City, Malibu, Santa Monica, and unincorporated communities including West Los Angeles, Ladera Heights, and portions of the Westside. The district also covers coastal communities along the Pacific from Malibu through the Palos Verdes Peninsula corridor in its southern reach.
Scope and coverage limitations: District 4's supervisorial authority applies to county-administered programs and the unincorporated portions of the district. Incorporated cities within District 4 — including Santa Monica — maintain their own city councils, city managers, police departments, and municipal services. The supervisor does not govern city-level decisions in those municipalities. Additionally, District 4 does not overlap with neighboring District 3 to the north or District 2 to the south and east. Regional transit, including Metro Rail lines serving the district, falls under the LA Metro Board of Directors, not the supervisor's direct authority, though the supervisor holds a seat on that board.
How it works
The District 4 supervisor is one of 5 members of the LA County Board of Supervisors, a body that serves simultaneously as the county's legislative and executive governing board. The supervisor is elected countywide within the district boundary by registered voters residing there.
The supervisor's institutional role includes the following functions:
- Budget authority — The Board of Supervisors adopts an annual county budget exceeding $40 billion (LA County CEO Office, Recommended Budget FY 2023-24). Each supervisor influences department allocations and discretionary funds for their district.
- Legislative votes — The supervisor votes on ordinances, land use decisions in unincorporated areas, contracts, and policy resolutions that apply countywide or to specific zones.
- Appointments — The supervisor appoints commissioners to advisory bodies including planning commissions, the Civil Service Commission, and the Commission on Human Relations.
- Constituent services — The District 4 office directly assists residents with navigating county departments including LA County Public Health, Social Services, Public Works, and the Assessor.
- Regional coordination — The supervisor coordinates with incorporated cities, the LA Metro Transit Authority, school districts, and state agencies on cross-jurisdictional projects.
Lindsey Horvath has served as the District 4 supervisor following her election in November 2022, succeeding Sheila Kuehl (LA County Elections). Her district office is located in West Hollywood.
Common scenarios
Residents and organizations within District 4 interact with the supervisor's office and county services in predictable categories:
- Unincorporated community residents seeking zoning variances, code enforcement responses, or road maintenance contact county Public Works and can escalate through the supervisor's constituent services office.
- Nonprofit organizations apply for county grants and contracts administered through departments that report to the Board, including the Department of Mental Health and the Department of Children and Family Services.
- Homeowners near coastal zones navigate the California Coastal Commission's state authority alongside county planning rules; the supervisor may file comment letters or coordinate with state agencies, but the Coastal Commission's decisions are not subject to supervisorial override.
- Cities contracting for sheriff services — Malibu, for example, contracts with the LA County Sheriff for law enforcement rather than operating an independent police department. The supervisor influences the Sheriff's budget through the Board but does not command the department directly.
- Transit riders using the E Line (Expo) or buses serving Culver City and the Westside interact with Metro's separately governed system, detailed on the LA Metro Bus Network and Rail System pages.
A comparison that clarifies scope: in incorporated cities like Culver City or Inglewood, elected city councils set local ordinances, police oversight, and zoning rules entirely independently of the supervisor. Residents there receive county services (county health clinics, probation, courts) but do not rely on the supervisor for municipal functions. In unincorporated communities, the supervisor functionally serves the combined role that a city council member and county representative would otherwise split.
Decision boundaries
Understanding what District 4's supervisor can and cannot decide prevents misdirected advocacy and service requests.
Within supervisorial authority:
- Votes on county budget line items, including departmental staffing levels
- Approval of contracts above thresholds set in the county's contracting rules
- Zoning and land use decisions in unincorporated District 4 communities
- Direction to the LA County CEO Office on administrative priorities
- Metro Board votes (the supervisor sits as an ex officio Board member)
Outside supervisorial authority:
- City council decisions in incorporated cities within the district
- California state statutes, regulations, or agency rulings (Coastal Commission, Caltrans, etc.)
- Federal programs administered directly through federal agencies
- LAUSD governance, which operates under a separately elected school board (LAUSD Governance)
- Judicial branch decisions, including those of the LA Superior Court, which is a state court
