City, county, and district responsibilities
The city line changes some rules, but not every public office.
The mailing address can say Vacaville 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 Vacaville, 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
Solano County handles property value and tax bills. It also handles deeds, elections, health, and many aid programs. Living inside Vacaville 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.
