The Maricopa County Assessor’s Office has launched a new online resource allowing users to freely download detailed datasets and bulk property reports directly from the Assessor’s website. These datasets, previously available only through formal requests or for purchase, are now accessible with just a few clicks.
For years, producing these reports required significant time and staff resources. With the implementation of the AA-GAMA assessment system in October 2022, the Assessor’s Office can now generate these datasets through automated processes, making public access faster, easier, and more efficient.
“This is another step forward in our commitment to transparency and exceptional customer service,” said 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.”
There are over a dozen reports and bulk files offered on the new Data Downloads page, including Geospatial data. Users can still access parcel-specific or individual account information by searching for and selecting the particular property on the Assessor’s Office website.
Members of the public who need information not included in the standard downloads can contact the Assessor’s Office for assistance at [email protected].
