Searching City of Wauwatosa Assessor Records
Data available
On the City of Wauwatosa Property Tax Inquiry portal, search by parcel number (9- or 10-digit) or by house number and street name without direction or street type. You can also filter by neighborhood/assessment area, sales criteria, or building/structure criteria. For year-to-year assessment comparisons, use the Assessor Assessment Search and enter the house number in both Low and High fields with only the street name (no N/S or St/Ave).
