How often is the Mapping Application’s data updated? Certain business processes can take several weeks for changes to be displayed on the web page. Please note: The map information (i.e. parcels, roads, lot dimensions, lot numbers, etc.) is updated daily and will reflect new parcel splits and combinations. In other words, the map portion may show the correct parcel, however, the attribute information may not yet be current. For further information, please contact the Yavapai County Assessor’s Office.
