City
Arcata
Arcata is an incorporated city in Humboldt County with an estimated 2025 population of 19,047. It handles many rules and services inside its limits. The county still handles property records, taxes, elections, public health, and many household programs.
Starting point
Confirm the address is inside local limits first.
If the address is inside Arcata, city offices may handle local permits, code, and services. If it is outside local limits, county planning or building may handle the work instead.
What changes the answer: A mailing city is not always the same as city government jurisdiction.

- Household help Open the benefits guide
CalFresh, Medi-Cal, CalWORKs, General Assistance, and IHSS
Humboldt County social-services agency is the main local office. Coverage, food, cash aid, and in-home support remain separate programs with separate notices.

Humboldt County public health is the local health jurisdiction. Health coverage and benefits still use separate programs and offices.

- Neighborhood services Open local-office help

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.

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.
- Tickets Open ticket help
Traffic court, parking citations, and toll notices
Humboldt County Superior Court handles traffic court matters. A city or issuing agency handles parking. The toll operator handles toll notices.
- Safety Open emergency checks

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

City, county, and district responsibilities
The city line changes some rules, but not every public office.
The mailing address can say Arcata even when the property sits outside local limits. Check the city line before relying on a local rule or permit page.
City limits choose the local permit office
Inside Arcata, the city usually handles permits, zoning, parking, business licenses, and local code. Outside the city line, start with county planning or building.
The county still handles county work
Humboldt County handles property value and tax bills. It also handles deeds, elections, health, and many aid programs. Living inside Arcata does not move those jobs to the city.
A provider can have its own boundary
Water, sewer, fire, schools, transit, trash, and power may belong to a special district or other provider. Use the address, parcel, or service bill to find the right agency.
