County

Los Angeles County

Los Angeles County has an estimated 2025 population of 9,694,934 across about 4,060.29 square miles of land. The county handles work tied to parcels, courts, records, elections, health, and countywide services. Cities inside it still set many permit and local-service rules.

Starting point

Start with the county layer.

County offices are the usual first stop for records, taxes, courts, elections, public health, social services, sheriff services, and unincorporated-area routing.

What changes the answer: Cities inside the county can still control city permits, local code, utilities, business licenses, and city-specific rules.

How local government works here

County and city rules can share one address.

An address in Los Angeles County can sit inside a city. It can also sit on county land outside any city. That line picks the permit desk and some local rules. It does not move every county job to city hall.

County jobs stay with the county

The county assessor sets property value. The tax collector handles bills. The recorder, court, elections office, benefits office, and usually the health office also stay with Los Angeles County. Berkeley, Long Beach, and Pasadena run separate city health departments.

Permits follow the city line

A city or town usually handles permits, zoning, parking, business licenses, and local code inside its lines. Los Angeles County handles these jobs on county land outside a city.

Districts can cross both layers

Water, sewer, fire, schools, transit, trash, and flood work may belong to a special district or other provider. The parcel or service bill is often the quickest way to name that agency.

Countywide answer

LA County property tax questions split between value and payment

Los Angeles County property tax questions usually split between the Assessor for value and ownership records, and the Treasurer and Tax Collector for bills and payments.

Local front desk

Start with the task in front of you.

Los Angeles County is the working county layer. Use the task rows for the division of work, then open the official office door below.

  1. Property

    Assessed value, exemptions, tax bills, and appeals

    Los Angeles County assessor handles value and exemptions. The clerk of the board handles a formal value appeal. The tax collector handles the bill, payment, and penalties.

    Open the property-tax path
  2. Records

    Deeds, birth and death records, marriage records, and name changes

    Los Angeles County recorder is the usual deed and public-record door. Vital-record access depends on the record and year. A legal name change or divorce decree can involve Superior Court.

    Open the records path
  3. Property work

    Building permits, ADUs, zoning, code, water, and septic

    For an unincorporated address, start with Los Angeles County planning or building. An address inside a city or town starts with that local permit counter.

    Open the local-office path
  4. Housing

    Rent rules, repairs, notices, and eviction papers

    Start with a local rent, housing, or code office if one serves the address. Court papers go to the Superior Court self-help path, and the deadline on the papers keeps running.

    Open the housing path
  5. Household help

    CalFresh, Medi-Cal, CalWORKs, General Assistance, and IHSS

    Los Angeles County social-services agency is the main local door. Coverage, food, cash aid, and in-home support remain separate programs with separate notices.

    Open the benefits path
  6. Public health

    Vaccines, disease reporting, health records, and local health programs

    Los Angeles County public health is the local health jurisdiction. Health coverage and benefits still use separate program doors.

    Open the health path
  7. Business

    Business setup, seller's permits, local licenses, and regulated work

    State filings and tax accounts do not replace county zoning, licensing, building, fire, or health approvals for the address.

    Open the business path
  8. Neighborhood services

    Potholes, streetlights, graffiti, trash, and service requests

    For a county-maintained road or service in an unincorporated area, start with Los Angeles County. Caltrans, utilities, transit systems, waste haulers, and special districts can own separate reporting paths.

    Open the local-office path
  9. School and care

    School enrollment, student records, and child-care checks

    The school district handles assignment and records. County offices can help with some family services, while the state licenses child-care facilities.

    Open the school and care path
  10. Parking

    Residential, guest, overnight, and local parking permits

    A local parking permit is separate from a citation, moving ticket, and toll notice. Match the permit to the address, vehicle, district, or parking facility.

    Open the parking path
  11. Tickets

    Traffic court, parking citations, and toll notices

    Los Angeles County Superior Court handles traffic court matters. A city or issuing agency handles parking. The toll operator handles toll notices.

    Open the ticket path
  12. Safety

    Emergency alerts, evacuations, smoke, roads, and power

    Use the county or city alert system for local warnings. Follow the local emergency office for evacuation wording, then use the state fire, smoke, road, and utility sources for the matching layer.

    Open the emergency path

Official county doors

Open the office that owns the next step.

California's statewide directories and verified official corrections supply the county-specific links below. Property and recorder links open the state directory because several county offices can share one task.
