City
San Bruno
San Bruno is an incorporated city in San Mateo County with an estimated 2025 population of 42,305. It handles many rules and services inside its limits. The county still handles property records, taxes, courts, elections, public health, and many household programs.
Starting point
Confirm the address is inside local limits first.
If the address is inside San Bruno, city or town offices may handle local permits, code, and services. If it is outside limits, county routing may be the better first stop.
What changes the answer: A mailing city is not always the same as city government jurisdiction.
How local government works here
The city line changes some rules, but not every public office.
The mailing address can say San Bruno 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 counter
Inside San Bruno, 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
San Mateo County handles property value and tax bills. It also handles deeds, court, elections, health, and many aid programs. Living inside San Bruno 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.

Local front desk
Start with the task in front of you.

- Property Open the property-tax path
Assessed value, exemptions, tax bills, and appeals
San Mateo 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
San Mateo 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 official city planning
Building permits, ADUs, zoning, code, water, and septic
Start with the city planning or building office for an address inside San Bruno. Start with the county for an address outside local limits.
Browse planning and building offices - 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
San Mateo 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
San Mateo 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 San Bruno zoning, licensing, building, fire, or health approvals for the address.
- Neighborhood services Open the local-office path
Potholes, streetlights, graffiti, trash, and service requests
For a city-owned street or service inside San Bruno, start with the local request system. County roads, Caltrans routes, utilities, private property, and separate service providers use different doors.
- 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
San Mateo 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 city doors
Start local when the address is inside San Bruno.
The official website is always here. Direct service links appear only when the California Porch source trail supports them; an unlisted service has not been guessed.
County handoff
Keep the county layer close.
San Bruno does not replace the county for records, property taxes, courts, elections, benefits, public health, or county alerts. The official doors stay together below.
