If a legal description for land in Mukwonago cites a lot number, the Mukwonago plat map is where those numbers come from. This Mukwonago guide covers: where to request a copy, how a plat differs from a parcel map, and the details that matter to buyers.
Getting started with the Mukwonago plat map
For a subdivision near Elkhorn, the deed usually cites the plat; bring that to the recorder's office or its online index.
Pulling up a parcel
Go first to the Walworth County parcel viewer; it includes each tax parcel around Delavan and Elkhorn. For acreage around Delavan, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Closer to Lake Geneva, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Land outside a subdivision
Rural land near Elkhorn that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Delavan.
Offices that can help
For assessment questions about property around Lake Geneva are handled by the county real property listing office, since that office keeps the assessment data. Questions about what you can build around Lyons need the planning or permitting office, and the answer depends on jurisdiction.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Lyons, so load it before you lose signal. A screenshot of the parcel near Elkhorn with its ID keeps working without signal.
Legal descriptions in Wisconsin
Wisconsin follows the Public Land Survey System, so rural legal descriptions near Lyons cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Lake Geneva vary in size. Write down the legal description for the tract near Delavan when you talk to a surveyor.
What the map can't tell you
Acreage on the record is a tax-roll number; only a licensed surveyor establishes the real boundary on land around Elkhorn. For a tract near Delavan, records update in batches, so a deed recorded last month can take weeks to appear.
When a plat changes
Lots near Lyons can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Lake Geneva show up in the records too.
When a parcel crosses a boundary
Walworth County touches Boone County, IL, McHenry County, IL, Jefferson County, Kenosha County, and Racine County, all with their own assessor records. Ground near Burlington that runs to the line can show up in two county records, so look at the neighboring map as well. For a tract near East Troy, the Platbookmapper state page lists every neighboring county map across Wisconsin.
A quick look at the area
Elkhorn holds the county offices, which is where the courthouse records live. You'll also find East Troy, Lyons, and Lake Geneva, where town lots give way to larger tracts. About 105,822 people live in Walworth County (Census estimate, 2023) spread over roughly 555 square miles. Walworth County was organized in 1839, and some chains of title near East Troy are long.
Mukwonago, WI: the basics
Mukwonago lies within Walworth County, Wisconsin, which means parcel data comes from the county. On ground around East Troy, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits out by Lyons often falls under county rules rather than the town's.
Recorded plat or GIS layer
The Walworth County parcel viewer draws parcels for taxes, whereas the plat carries surveyed dimensions.
The paper trail behind a parcel
Out toward Burlington, the map is an index, not the title: deeds, plats and easements for parcels in the county sit with the Register of Deeds. Out toward Burlington, use the book and page from the tax record so staff can find the deed fast.
Reading the plat sheet
Easements on the plat near East Troy can block a shed or pool; read the notes on the sheet.
Getting a copy
For property near Lake Geneva, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
