Searching City of West Allis Assessor Records
Data available
From the Assessor's Office page, use Property Record Card Search (GIS Mapping Site) to look up parcel details, assessment summaries, and sales history. The page's Property Search link opens OpenGov Property Information, where you can use Search for permits, licenses, and historical property documents by address. A legacy free City Property Search at apps.westalliswi.gov also accepts house number plus street name (e.g. 7525 Greenfield), tax key in NNN-NNNN-NNN format, or water account number. Completed assessment rolls are posted as downloadable PDFs on the Assessor's Office page.
Additional Information
The City of West Allis Assessor's Office maintains ownership information and values taxable property in the city under the Wisconsin Property Assessment Manual and Chapter 70. The official office page on westalliswi.gov links to free public tools for property and assessment information. Property Record Card Search provides parcel/assessment detail and sales history via the city's ArcGIS experience. OpenGov Property Information supports address search for permits, licenses, and historical property documents, and the Assessor's Office posts completed real estate and mobile home assessment rolls as PDFs. The Assessor values property only and does not answer tax-bill questions.
