The Whitefish Bay plat map: start here
For a lot in Whitefish Bay, look for the plat book reference on the parcel record; use it to request a copy.
Getting to the right map
Begin with the Milwaukee County parcel viewer; it maps every tax parcel from Fox Point to Brown Deer. On ground around West Milwaukee, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Closer to Shorewood, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements covering ground around Shorewood are filed with the Register of Deeds. Older tracts around Fox Point can go back through many deeds, and a title company is worth hiring before a purchase.
Whitefish Bay and the county around it
Whitefish Bay is part of Milwaukee County, Wisconsin, which means parcel data comes from the county. For land near Brown Deer, 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 near Shorewood generally answers to county rules, not municipal ones.
Amended plats
An amended plat may change lots around West Milwaukee, search the index for replats of the same subdivision; street vacations near Wauwatosa show up in the records too.
How land is described here
Wisconsin follows the Public Land Survey System, so rural legal descriptions near Fox Point cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Wauwatosa can be irregular. Copy the legal description from the record for the parcel near Wauwatosa when you talk to a surveyor.
Metes and bounds instead
Rural land near Wauwatosa that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Brown Deer.
Plat map vs. parcel map
The Milwaukee County parcel viewer draws parcels for taxes, whereas the plat carries surveyed dimensions.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Wauwatosa can sit several feet off the line on screen. For a parcel near Brown Deer, owner names and values update on a schedule, so a deed recorded last month may not show yet.
A quick look at the area
Milwaukee serves as the county seat, where most land records are kept. Other places on the map include Shorewood, Fox Point, River Hills, and Brown Deer. Roughly 916,205 people live in Milwaukee County (Census estimate, 2023) spread over roughly 241 square miles. Milwaukee County dates to 1835, and some chains of title near Shorewood are long. Places such as Menomonee River and Kinnickinnic River make handy reference points on the map near Wauwatosa.
Reading the plat sheet
Easements on the plat near River Hills limit where you can build or fence; read the notes on the sheet.
Ordering the Whitefish Bay plat map

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 River Hills may be split in two county records, so check the neighboring map too. For a home near West Milwaukee, the Platbookmapper state page links each bordering county map for Wisconsin.
Getting answers from the right desk
For assessment questions about property around Brown Deer belong with the county real property listing office, the office behind the parcel record. Zoning, permits and septic questions near Wauwatosa are for the local planning and health departments, town or county, depending on location.
On site with the map
Most viewers work in a phone browser, handy when you're parked on a road near Shorewood, but coverage can be spotty out of town. A printout of the tract near West Milwaukee keeps working without signal.
