City
Santa Rosa
Santa Rosa is an incorporated city in Sonoma County with an estimated 2025 population of 179,437. 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 Santa Rosa, 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.
Place answer
Santa Rosa water billing and field problems use different numbers
Water Billing opens and closes city water or sewer accounts with one business day's notice. Leaks, sewer maintenance, and after-hours emergencies use different service lines.

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

For a city-maintained street or service inside Santa Rosa, start with the local request system. County roads, Caltrans routes, utilities, private property, and separate service providers use different reporting systems.

The official website is always listed. A direct service link appears only after an official public page has been checked; an unlisted service has not been guessed.
County offices
County offices still handle countywide work.
Santa Rosa does not replace the county for records, property taxes, courts, elections, benefits, public health, or county alerts. The official links stay together below.
Sonoma County
City, county, and district responsibilities
The city line changes some rules, but not every public office.
The mailing address can say Santa Rosa 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 Santa Rosa, 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
Sonoma County handles property value and tax bills. It also handles deeds, elections, health, and many aid programs. Living inside Santa Rosa 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.
