Parcel Search

* * * ATTENTION * * *

Due to an ongoing conversion of the county property tax assessment software, property information found in ParcelQuest is current as of June 30, 2020.

Please call the Trinity County Assessor's Office at (530) 623-1257 or e-mail using the link at the bottom of this page for property updates occurring after June 30, 2020.

Thank you for your patience during this conversion.


The Parcel Search tool will allow you to find your property by Assessor’s Parcel Number (APN). The Parcel Search tool will not search by situs address at this time. The Parcel Detail screen will show your Use Type, Tax Rate Area, and *Mailing Address. The Value Screen will show your Land Value, Improvement Value, Exemption Status, and Total Assessed Value.

*To confirm a Physical Address, please contact the Trinity County Planning Department

The accuracy of map data varies from location to location in the county. While Assessor Parcel maps are useful for assessment purposes, it should not be relied upon to determine property, zoning or general plan designation boundaries or be used in any way for project design. All map data should be verified before it is materially relied upon for property or project planning. In urban areas the assessor's map data may be inaccurate by as much as 50 feet in any direction. In rural areas the map data may be inaccurate by as much as 400 feet in any direction.
