If a legal description for land in Vacaville cites a lot number, the Vacaville plat map is where those numbers come from. In this Vacaville guide: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Getting started with the Vacaville plat map
For land around Benicia, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Opening the official parcel viewer
Go first to the Solano County parcel viewer; it maps every tax parcel around Rio Vista and Suisun City. Out toward Fairfield, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For acreage around Vallejo, write down the parcel ID from that panel; each records desk in the county uses it to find the file.
Land outside a subdivision
Acreage around Suisun City outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Vallejo.
City limits and county records
Vacaville lies within Solano County, California, and the county assessor maps its lots. For property near Suisun City, City or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits near Benicia generally answers to county rules, not municipal ones.
A word on accuracy
Acreage on the record is an assessed number; only a licensed surveyor establishes the real corners for a parcel near Rio Vista. For acreage around Suisun City, owner names and values update on a schedule, so a deed recorded last month might lag behind.
A quick look at the area
Fairfield holds the county offices, which is where the courthouse records live. Smaller places on the map include Suisun City, Dixon, and Rio Vista. Roughly 449,218 people live in Solano County (Census Bureau estimate, 2023) spread over about 822 square miles. Landmarks such as San Pablo Bay National Wildlife Refuge help you orient on the aerial around Suisun City.
Legal descriptions in California
California follows the Public Land Survey System, so deeds around Vallejo reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Dixon odd-sized. Copy the legal description from the record for the parcel near Benicia when you talk to a surveyor.
Replats and vacations
Lots near Dixon can be combined or reconfigured by a replat, so check for later filings; street vacations near Fairfield show up in the records too.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Vallejo, so load it before you lose signal. A screenshot of the parcel near Suisun City with its ID is a good backup.
Next door to Solano County
Solano County borders Contra Costa County, Marin County, Napa County, Sacramento County, and Sonoma County; every one of them runs a separate parcel map. Acreage along the edge near Rio Vista may show up across two assessors' files, so check the neighboring map as well. Out toward Benicia, our state page links every bordering county map across California.
Which office to call
Anything recorded against property around Fairfield sit in the index kept by the County Recorder, often with an online index. Questions about what you can build around Benicia need the planning or permitting office, depending on whether the land is inside town limits.
Recorded documents worth pulling
