The map also labels unincorporated places, Allendale, Elmira, and Green Valley among them. By Census Bureau figures, the county had roughly 449,218 residents in 2023, spread over about 822 square miles of land. Development is heavy around Suisun City, so lot-by-lot subdivision plats dominate the map near the population centers. San Pablo Bay National Wildlife Refuge is a big draw, and the private tracts that border public land are often the first ones hunters and cabin buyers ask about.
Who uses the Solano County parcel map
For a new build outside Dixon, the parcel record supplies the lot size and legal description a site plan needs. A buyer comparing houses in Benicia and Dixon can line up the lot sizes side by side before booking showings. An owner in Benicia planning a fence or an outbuilding pulls the parcel first, then the recorded plat.
Acreage and vacant lot search
Here's a simple routine for finding open ground in Solano County using the parcel map:
- Run the aerial layer along I-680 and the side roads off it, flagging any tract with no structures.
- For the open ground around Vacaville, copy the owner, acreage and mailing address into a simple spreadsheet.
- Compare the record's land value against similar parcels on the same road out of Dixon.
- Make sure the parcel near Dixon actually touches a public road, and ask how it's reached if it doesn't.
- Before you sign for land near Rio Vista, check what the local planning and health offices will allow on it.

Are the Solano County property lines accurate?
