Assessor Maps and Property Information Using ParcelQuest Lite
The ParcelQuest Lite search tool allows you to view parcel maps, assessed values, and details about houses in a simple and easy-to-use way.
ParcelQuest Lite will allow you to find a property by Assessor's Parcel Number (APN) or by street address. Some parcels, such as vacant land, do not have street addresses and an APN will be necessary to perform a search.
