Assessment Data

The Equalization Division annually compiles ASSESSMENT DATA for Wayne County communities at the conclusion of the March Board of Review. This is not real-time data, but it is updated periodically. We can provide this data in fixed length and comma delimited ASCII and CSV formats. Custom exports are available at an additional charge. Please click this link to download a Data Service Request Form for a list of available services for our communities. Also, please note that Assessment Data will be retrospective to the prior March Board of Review for most communities. For information and pricing of custom data extracts, please contact:

Tax Parcel Maps are maintained at the local communities and copies may be obtained by contacting them directly, usually at their Assessor's office. Historical maps are available and downloadable and may be found under the Historical Tax Maps link.

The Equalization Division no longer offers GIS data. All orders must be done through the local assessment offices whose contact information can be found by clicking the Employee Directory located to the right side of this page. Historical parcel boundary shape files are available and downloadable and may be found under the Wayne County GIS Parcel Layer Shapefiles link.

Additional mapping options are now also available and assessible at the Wayne County Open Data Portal.
