Locating & Mapping
Address of Property
The Assessor is responsible for maintaining two addresses associated with each property in Napa County.
Assessor Parcel Maps
You can search for Napa County maps filed with the County Recorder by title, date filed, map data (map type, book number, page number), by map number or by location.
Creating New Parcels
Maps or deeds filed or recorded between January 1 and December 31 create new parcels that will not appear on the tax roll until the following fiscal year, July 1 to June 30. To avoid the taxes going delinquent on the "parent" parcel that will be modified, local agencies are authorized to collect prepayment of property taxes
The most common reason that a parcel is landlocked is that the owner of a parcel that does have access to a public road sells the portion of the parcel with road frontage or access and retains a separate parcel but neglects to keep a deeded access easement across the parcel with public road access.

Property Boundary Disputes
One of the most frequent questions that property owners ask of the Assessor is the location of the boundary between their property and that of a neighbor, or the location of their property line in relationship to the edge of a public right of way, such as a street. Learn more about boundary disputes.
Records of Survey
One method of locating, describing and measuring private parcels is the record of survey. A record of survey is prepared by a licensed land surveyor or civil engineer authorized to practice land surveying using the most current technology and supplemented by research of records on prior surveys and property transfers.
Property owners and prospective buyers often ask about easements that impact the property they own or are interested in buying. Easements are a private matter settled in court.
When a Parcel is Not a Parcel
One of the primary duties of the County Assessor is to locate all taxable property in the county. Location of land is based on a series of maps which are divided into books (45), pages (1750), blocks and parcels (45,382). The Assessor Parcel Number (APN) of each property in the county is keyed to those maps
