Opening the official parcel viewer
Begin with the Milwaukee County parcel viewer; it maps every tax parcel from South Milwaukee to West Milwaukee. If the land is near West Milwaukee, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Closer to Greendale, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and often a sale date.
City limits and county records
Cudahy is part of Milwaukee County, Wisconsin, so its parcels are on the county's map. With a lot near West Milwaukee, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits near Oak Creek generally answers to county rules instead.

Reading the legal description

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near St. Francis vary in size. Copy the legal description from the record for the parcel near Oak Creek when you talk to a surveyor.
Before you lean on the lines
Listed acreage is an assessed number; just a licensed surveyor sets the real boundary for a parcel near South Milwaukee. In and around Greendale, owner names and values update on a schedule, so a deed recorded last month may not show yet.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements covering ground around St. Francis sit with the Register of Deeds. Inherited tracts around South Milwaukee may trace back through a long string of deeds, and a title company earns its fee if money is changing hands.
When there's no plat
Acreage around West Milwaukee outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near West Allis.
Amended plats
Lots near West Milwaukee can be combined or reconfigured by a replat, so check for later filings; vacated streets or alleys also get recorded.
