Maricopa County Assessor’s Office Launches Free Bulk Data Downloads

The Maricopa County Assessor’s Office announced a significant expansion of public access to property information with the launch of a new online Data Downloads page. Users can now freely download detailed bulk datasets and comprehensive property reports directly from the Assessors website—no formal requests or fees required.

Previously, these extensive reports and datasets were available only through time-consuming formal public records requests or by purchase. With the successful implementation of the AA-GAMA assessment system in October 2022, the Assessor’s Office has automated the generation of these files, dramatically reducing staff time and making the information instantly accessible.

“This is another step forward in our commitment to transparency and exceptional customer service,” explained Maricopa County Assessor Eddie Cook. “Our team has worked hard to modernize our systems so property owners and members of the public can get the information they need without barriers, delays, or unnecessary costs. Making these datasets freely available helps ensure our property tax system remains open, accessible, and easy to understand.”

The new Data Downloads page features more than a dozen different reports and bulk files, including valuable geospatial data. In addition to these bulk options, users can still search for and view detailed information on individual parcels or accounts directly through the Assessor’s Office website.

The initiative reflects the Assessor’s ongoing efforts to leverage technology to serve Maricopa County residents more efficiently while maintaining the highest standards of openness in government operations.
