When land near Oak Creek catches your eye, the Greendale GIS map shows lines, owner names and parcel numbers. What this Greendale guide covers: which viewer to open, the fastest ways to search, and what to double-check with records.
Opening the Greendale GIS map: start here
Parcel maps here are usually run by the county, not the town, and for Greendale that means the Milwaukee County parcel viewer.
Where the parcel data lives
Begin with the Milwaukee County parcel viewer; it covers each assessed parcel in the county, West Allis included. For a tract near St. Francis, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near West Allis, write down the parcel ID from that panel; every clerk in the county uses it to find the file.
What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so a fence near St. Francis may sit some distance off the line on screen. For a tract near West Milwaukee, records update in batches, so a deed recorded last month might lag behind.
Keeping a record
Print or screenshot the parcel near West Milwaukee with its ID visible, which helps later when you ask the assessor or a title company.
Deeds, plats and who keeps them
Before you sign anything, request the recorded deed through the Register of Deeds; the parcel map near West Milwaukee only summarizes it. If the land is near Oak Creek, have ready the instrument number shown in the record panel and the lookup takes minutes.
Land on the county line
Milwaukee County borders 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 Cudahy may be split across two assessors' files, so open the neighboring map too. With a lot near St. Francis, our state page links every neighboring county map across Wisconsin.
Who handles what
If the acreage or value on a parcel near Cudahy looks off are handled by the county real property listing office, which maintains the tax roll. Building or septic questions for a lot near West Allis are for the local planning and health departments, and the answer depends on jurisdiction.
Where Greendale fits in
The town is part of Milwaukee County, Wisconsin, so its parcels are on the county's map, at least around Oak Creek. If the land is near Oak Creek, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits out by West Allis usually falls under county rules rather than the town's.
Sections, lots and bearings
Wisconsin follows the Public Land Survey System, so deeds around St. Francis reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Cudahy can be irregular. Copy the legal description from the record for the parcel near West Allis for any title or survey request.
Search tips
Addresses are the easiest route inside Greendale; for owner searches, try last name first. If you're looking near St. Francis, searching by parcel number never misses, and it carries over to every office in the county.
Browser tips
If the viewer stalls on a phone near Oak Creek, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Places you'll see on the map
Milwaukee is the county seat, which is where the courthouse records live. Other places on the map include Hales Corners, West Allis, West Milwaukee, and Oak Creek, where town lots give way to larger tracts. Around 916,205 people call Milwaukee County home (Census estimate, 2023) spread over some 241 square miles. Milwaukee County dates to 1835, and some chains of title near Cudahy are long. Features like Menomonee River and Kinnickinnic River help you orient on the aerial around Cudahy.
Beyond the parcel lines
Toggling imagery near Cudahy helps you see where buildings sit inside the lines.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near West Milwaukee, though signal can drop in rural spots. A saved image of the lot near West Allis and its lines keeps working without signal.
Owner, value and acreage
A parcel card near Oak Creek normally gives owner, mailing address, assessed value and acreage.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
