Land questions in Yolo County start in the same place: the official parcel map. Here's how to use the Yolo County GIS map to find owners, acreage and boundary lines, and where it falls short.
The sections below cover the map itself, the towns from Winters to Dunnigan, and the deeds and surveys that settle what the map can't.
Who uses the Yolo County parcel map
- Before an offer, buyers in Yolo County pull the parcel to confirm the lot dimensions and look for anything odd, like a flag lot or a shared drive.
- For a new build outside West Sacramento, the parcel record supplies the lot size and legal description a site plan needs.
- If you hunt the country around Dunnigan, the owner layer tells you who to ask and where the next property begins.
Getting into the Yolo County ArcGIS parcel map
The official map is the Yolo County ArcGIS parcel map, which runs on an Esri ArcGIS web map. Once parcel lines appear, click any tract near West Sacramento to see who owns it and how many acres the county records. Bookmark the Platbookmapper page for Yolo County too; we update it when the official map moves.
The lay of the land in Yolo County
The county seat is Woodland; Davis, West Sacramento, and Winters are among the other communities you can zoom to. The Census Bureau puts Yolo County at about 1,015 square miles of land and an estimated 220,544 people (2023). Much of Yolo County is built out, so the parcel map is busiest with subdivision lots, though rural edges and undeveloped tracts still turn up.
Reading property lines on the Yolo County GIS map
On rural tracts near Dunnigan, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. Out past West Sacramento, rural deeds usually cite a section, township and range, and those section lines often show on the parcel layer. A survey is the only document that settles where a Yolo County boundary actually runs.
Work and land use in Yolo County
In the 2022 County Business Patterns data, Yolo County had 4,444 establishments; professional and technical services, retail trade, and health care and social assistance led the count. Relative to the U.S. as a whole, Yolo County is heavy on beverage and tobacco manufacturing, agriculture and forestry support services, and food manufacturing. Around Woodland, a wooded tract on the map may be a working forest; recent aerials and the deed will show whether timber rights were reserved. Keep that in mind when you compare parcels in Yolo County: who works here shapes what land sells.
Where Yolo County deeds and plats are kept
The map near Davis is only as good as the deeds behind it, and those are kept in the county's recording office. The office title varies by state (register of deeds, recorder, county clerk or clerk of court), so check the Yolo County government website for the right one. Rural tracts near Dunnigan may go back through several deeds; the instrument number on the record is the first link in that chain.
Data limits to keep in mind
A lot in Winters that sold last month may still show the previous owner on the map. Treat Yolo County acreage figures as estimates until a survey confirms them.
Neighboring counties
A farm that runs from Yolo County into Lake County will have separate parcel records on each side; the other neighbors are Colusa County, Napa County, Sacramento County, and Solano County. Neighboring maps for Yolo County are a click away on our California page.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
