Where the parcel data lives
Begin with the Milwaukee County parcel viewer; it covers every assessed parcel from West Milwaukee to St. Francis. If you're looking near Wauwatosa, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near West Allis, write down the parcel ID before closing the panel; every records desk in the county uses it to find the file.
Hales Corners, WI: the basics
Hales Corners lies within Milwaukee County, Wisconsin, and the county assessor maps its lots. For a parcel near Greendale, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the city limits out by West Milwaukee usually follows county rules rather than the town's.
Before you lean on the lines
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near St. Francis can sit some distance off the line on screen. For a home near West Milwaukee, records update in batches, so a deed recorded last month might lag behind.
Getting your bearings
Milwaukee is the county seat, home to the main records offices. Smaller places on the map include Greendale, West Allis, West Milwaukee, and Wauwatosa.
