Where St. Francis fits in
St. Francis lies within Milwaukee County, Wisconsin, so its parcels are on the county's map. Out toward West Milwaukee, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits out by West Allis generally answers to county rules, not municipal ones.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements for land near Greendale sit with the Register of Deeds. Older tracts near West Milwaukee may trace back through a long string of deeds, so a title company can sort it out if money is changing hands.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Greendale can sit some distance off the line on screen. Closer to Cudahy, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Searching the map
Addresses are the easiest route inside St. Francis; for owner searches, try last name first. For land near Greendale, searching by parcel number never misses, and it's printed on tax bills.
Layers worth turning on
Closer to West Allis, look in the layer list for municipal boundaries, floodplain and sometimes zoning; not every viewer has them all.
Land on the county line
Milwaukee County meets Muskegon County, MI, Ottawa County, MI, Ozaukee County, Racine County, and Washington County, and each of those keeps its own parcel map. Acreage along the edge near Oak Creek may show up across two assessors' files, so open the neighboring map before you assume the acreage. For a parcel near West Allis, the Platbookmapper state page links every bordering county map across Wisconsin.
