For any lot around South Milwaukee, the Oak Creek GIS map shows lines, owner names and parcel numbers. This Oak Creek guide covers: which viewer to open, how to search it, and what to double-check with records.
Opening the Oak Creek GIS map
In most places the county maintains the parcel layer, which makes the Milwaukee County parcel viewer the main source for lots in Oak Creek.
Getting to the right map
Your first stop is the Milwaukee County parcel viewer; it maps every tax parcel from West Milwaukee to Hales Corners. For land near Cudahy, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a home near South Milwaukee, the parcel card normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
When the map won't load
If the viewer stalls on a phone near Cudahy, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Recorded documents worth pulling
When the details count, get the recorded deed through the Register of Deeds; the parcel map near Cudahy only summarizes it. Long-held tracts near Hales Corners can go back through several deeds, so a title company can sort it out if money is changing hands.
Legal descriptions in Wisconsin
Wisconsin follows the Public Land Survey System, so rural legal descriptions near Greendale cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Hales Corners can be irregular. Copy the legal description from the record for the parcel near South Milwaukee for any title or survey request.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Cudahy, but coverage can be spotty out of town. A printout of the tract near South Milwaukee keeps working without signal.
Offices that can help
For assessment questions about property around Greendale go to the county real property listing office, the office behind the parcel record. Building or septic questions for a lot near South Milwaukee are for the local planning and health departments, depending on whether the land is inside town limits.
City limits and county records
Oak Creek lies within Milwaukee County, Wisconsin, and the county assessor maps its lots. Closer to Greendale, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits out by St. Francis often falls under county rules rather than the town's.
Milwaukee County in a few facts
Milwaukee is the county seat, home to the main records offices. You'll also find South Milwaukee, Cudahy, St. Francis, and Greendale, where town lots give way to larger tracts. Roughly 916,205 people live in Milwaukee County (Census Bureau estimate, 2023) on roughly 241 square miles. Milwaukee County dates to 1835, and some chains of title near West Milwaukee are long. Landmarks such as Menomonee River and Kinnickinnic River make handy reference points on the map near St. Francis.
Next door to Milwaukee County
Milwaukee County touches Muskegon County, MI, Ottawa County, MI, Ozaukee County, Racine County, and Washington County; every one of them runs a separate parcel map. Ground near Hales Corners that runs to the line can be split across two assessors' files, so open the neighboring map as well. For land near Greendale, the Platbookmapper state page lists every neighboring county map across Wisconsin.
Before you lean on the lines
The acreage figure is an estimate; only a licensed surveyor can set the real corners on land around Hales Corners. In and around Hales Corners, records update in batches, so a deed recorded last month might lag behind.
Finding the right lot
Addresses are the easiest route inside Oak Creek; owner names are usually entered last name first. Around St. Francis, searching by parcel number never misses, and you'll find it on tax statements.
Beyond the parcel lines
For property near Cudahy, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
What the record panel tells you
Recent sales on nearby lots near South Milwaukee give a rough idea of values; an appraiser is the real authority.
Printing and saving
Save a screenshot of the lot near Cudahy and its record panel, which helps later when you ask the assessor or a title company.
