Find the right local office
The address and the task decide which public office handles the work. Match permits, taxes, court papers, utilities, and local services to the right office.
The short version
The address and the job choose the office
For local permits and services, the boundary decides the counter. An address inside city limits usually starts with the city, while an address on unincorporated land starts with the county. Property tax has three main county jobs: the assessor sets taxable value, the auditor-controller computes the tax, and the tax collector mails and collects the bill. Courts and state agencies have separate jobs: courts handle cases and filing dates, while state agencies handle statewide licenses, benefits, labor rules, and DMV records. A water, sewer, fire, school, or transit district can have its own office too.
What changes the answer: The city name in a mailing address does not show that the property is inside that city. Use the address or parcel number to confirm the boundary, and use the office named on a notice when a deadline is already running.
A mailing city, legal city limit, county, court, state agency, and special district can all point to different offices. The address and the task identify the office responsible for the next step.
How it works
City limits decide the local permit counter
A city usually handles zoning, building permits, code cases, streets, and other city services inside its legal boundary. The county handles those local jobs on unincorporated land. A postal city name is only for mail and can cross that boundary.
A common case is a home with a familiar city in its address but no city government for the parcel. That owner starts with county planning or building, not the nearby city hall. The parcel number is the cleanest key when the address is unclear.
County tax offices are not interchangeable
The assessor identifies property, sets assessed value, and handles many exemptions and value questions. The auditor-controller uses that value and the tax rate to compute the tax. The tax collector sends the bill, takes payment, and handles current or late payment records.
The county recorder keeps deeds and many recorded documents. An assessment appeal goes through the county's appeal process, not the tax collector. Bring the parcel or account number so the office can find the same record you are looking at.
Court papers stay with the court
A city, county department, or state agency cannot extend a court filing date. A summons, complaint, citation, hearing notice, or court order belongs with the court named on the paper. Use that court's clerk or self-help center for forms and case steps.
A local housing office, labor office, or consumer agency may still help with the subject. It does not replace a response that must be filed in court. Treat the court date and the agency complaint as separate tracks.
State agencies own statewide records and licenses
DMV handles driver and vehicle records. EDD handles unemployment, disability, paid family leave, and employer payroll accounts. State labor offices handle wage claims and job injuries. State boards handle insurance, contractors, and many licensed professions.
Local approval can still sit beside a state license. A contractor license does not issue a building permit. A state business filing does not approve a storefront. Check both the state license and the local approval when the work and the address each need approval.
A special district may own the service
Water, sewer, fire protection, flood control, transit, parks, and schools can be run by districts with their own boundaries. Those lines do not have to match a city or county service area. The utility bill, tax bill, or service notice usually names the district.
Start with the name printed on the real record. If the first office does not own the job, ask for the office name, official page, and case or reference number. That keeps the handoff tied to the same task.

- 1
Write down the address and the exact task. Add the parcel number, notice date, and deadline if you have them.
- 2
For property work, check whether the address is inside city limits or on unincorporated county land. The mailing city alone cannot tell you.
- 3
For assessed value, ownership records, or exemptions, start with the county assessor. To pay the bill or ask about penalties, start with the county tax collector.
- 4
For zoning, building permits, ADUs, or local code, start with the city permit counter if the address is in a city. If it is unincorporated, start with county planning or building.
- 5
For coastal-zone work, ask who handles the coastal permit: the city, the county, or the Coastal Commission. Do not assume one permit covers everything.
- 6
For rent, eviction notices, or housing papers, check the local rent or housing office first. If a court deadline is involved, use court self-help or legal help.
- 7
For pay, breaks, benefits, or job injuries, start with the state labor office, EDD, or workers' comp office that fits the issue.
- 8
For cars, titles, registration, smog, or fees, start with DMV or the Bureau of Automotive Repair.
- 9
For insurance, contractor, or license issues, start with the state license or consumer office before sending money or signing.
- 10
If an office says it is not the right place, ask which office has the job. Ask for the official page or case number too.
Watch for
- 1
A postal city name is not always the city government. Some homes have a city mailing address but are handled by the county.
- 2
The assessor, tax collector, planning office, recorder, and court are different offices.
- 3
Special districts can handle water, sewer, fire, lighting, parks, or flood control. School districts are their own separate thing.
- 4
City hall handles city services. It cannot decide a court case, an insurance claim, a tax appeal, or a state license.
- 5
Search results can point to look-alike pages. Use official agency pages and the numbers printed on real notices.
- 6
If a deadline, eviction, job loss, insurance problem, tax bill, permit denial, court paper, or safety issue is on the line, use the official source and get qualified help.

Current forms, fees, deadlines, and instructions from the agencies responsible for them.
Use this to sort the issue and find the official source. It cannot decide your rights or tell you what to file. When a deadline, denial, eviction, firing, injury, tax bill, permit dispute, or insurance claim is involved, use the current official page and get qualified help when needed.
