When a listing near Menomonee Falls mentions a lot number, you'll need the Brookfield plat map to make sense of it. Covered here for Brookfield: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Tracking down the Brookfield plat map
For a subdivision near Pewaukee, the deed usually cites the plat; that makes the request quick.
The free map to start with
Begin with the Waukesha County parcel viewer; it maps every assessed parcel around Pewaukee and Menomonee Falls. With a lot near Sussex, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Elm Grove, write down the parcel ID from that panel; each clerk in the county will want it.
Getting answers from the right desk
If the acreage or value on a parcel near Elm Grove looks off belong with the county real property listing office, since that office keeps the assessment data. Building or septic questions for a lot near Menomonee Falls need the planning or permitting office, depending on whether the land is inside town limits.
Limits of the parcel data
Acreage on the record is an assessed number; only a licensed surveyor can set the real lines for a parcel near New Berlin. With a lot near Sussex, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Recorded documents worth pulling
For anything that matters, request the recorded deed through the Register of Deeds; the parcel map near Elm Grove only summarizes it. Long-held tracts around Menomonee Falls may trace back through several deeds, so a title company earns its fee if money is changing hands.
Field tips
Most viewers work in a phone browser, useful out on a road near Lannon, but coverage can be spotty out of town. A screenshot of the parcel near Lannon with its ID is a good backup.
Brookfield and the county around it
Brookfield lies within Waukesha County, Wisconsin, which means parcel data comes from the county. For land near Sussex, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the city limits out by Sussex usually follows county rules instead.
Neighboring parcel maps
Waukesha County borders Dodge County, Jefferson County, Milwaukee County, Ozaukee County, and Racine County; every one of them runs a separate parcel map. Ground near Menomonee Falls that runs to the line can be split across two assessors' files, so look at the adjacent map before you assume the acreage. For land near Pewaukee, our state page links each neighboring county map across Wisconsin.
Plat map vs. parcel map
If the tax map and plat differ near Lannon, trust the recorded documents over the GIS layer.
Waukesha County in a few facts

Metes and bounds instead
Rural land near Pewaukee that was never subdivided may have no plat at all; look for a recorded survey for land there.
What a plat shows
For a parcel near Lannon, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Sections, lots and bearings

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Menomonee Falls vary in size. Write down the legal description for the tract near Elm Grove when you talk to a surveyor.
Requesting the plat
Around Elm Grove, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
Amended plats
