Welcome to the Ada County Assessor's Division of Land Records/GIS site. This site was created in order to assist the public with locating information about property within Ada County. The Ada County Assessor's Office is dedicated to GIS Services in order to better serve the public.
Currently we provide property information, access to Records of Survey, Subdivision Plats, and Interactive Maps.
Our online image document server provides access to Records of Survey, Subdivision Plats, and Section Maps. If you have an account, please login, otherwise you may use the username public and password public. Please read our documentation for further assistance using this system.
Our online maps allow you to interact with our GIS data. Currently our maps include parcel boundaries, streets, hydrography, section boundaries, city limits, parks, and schools.
