CDP
Westhaven-Moonstone
Westhaven-Moonstone is a Census-designated community in Humboldt County covering about 8.091 square miles. It is not an incorporated city. The county is usually the first government layer, while utilities and special districts can follow their own boundaries.
Starting point
Start with the county unless an official district says otherwise.
A Census-designated place is a useful local name, but it usually does not have its own city hall. For permits, records, taxes, courts, and many services, begin with the county layer.
What changes the answer: Special districts, utilities, schools, fire agencies, parks, water agencies, coastal rules, and state maps can still control a specific issue.
How local government works here
The place name, county, and service districts do different jobs.
Westhaven-Moonstone is a real community name. It does not create a city government. The county and local districts divide the public work for the address.
The community name is not city hall
Westhaven-Moonstone is what the Census calls a census-designated place. It normally has no mayor, city council, or city permit desk. Start with Humboldt County for county work.
The county handles the local government lane
County planning and building usually handle an address outside a city. The county also handles property value, tax bills, records, courts, elections, health, and many aid programs.
Services may come from separate districts
Water, sewer, fire, schools, parks, roads, trash, and power can follow lines that do not match the place name. Check the bill, parcel, or district map before assuming the county provides the service.

Local front desk
Start with the task in front of you.
Westhaven-Moonstone is a Census-designated place, not an incorporated city. Start with Humboldt County; utilities and special districts can still have their own boundaries.
- Property Open the property-tax path
Assessed value, exemptions, tax bills, and appeals
Humboldt 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.
- Records Open the records path
Deeds, birth and death records, marriage records, and name changes
Humboldt 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.
- Property work Open the local-office path
Building permits, ADUs, zoning, code, water, and septic
Start with Humboldt County planning or building. Water, sewer, fire, and other special districts may have a separate approval.
- Housing Open the housing path
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.
- Household help Open the benefits path
CalFresh, Medi-Cal, CalWORKs, General Assistance, and IHSS
Humboldt County social-services agency is the main local door. Coverage, food, cash aid, and in-home support remain separate programs with separate notices.
- Public health Open the health path
Vaccines, disease reporting, health records, and local health programs
Humboldt County public health is the local health jurisdiction. Health coverage and benefits still use separate program doors.
- Business Open the business path
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.
- Neighborhood services Open the local-office path
Potholes, streetlights, graffiti, trash, and service requests
Start with Humboldt County for county-maintained roads and services. Caltrans, utilities, transit systems, waste haulers, and special districts can own separate reporting paths.
- School and care Open the school and care path
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.
- Parking Open the parking path
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 the ticket path
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 the emergency path
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.
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.
