Buying a lot in a subdivision near Oconomowoc? What you want is the Delafield plat map, because the recorded plat shows how the land was divided. What this Delafield 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 Delafield plat map
For a subdivision near Wales, look for the plat book reference on the parcel record; use it to request a copy.
Opening the official parcel viewer
Go first to the Waukesha County parcel viewer; it maps every tax parcel around Chenequa and Oconomowoc Lake. On ground around Oconomowoc Lake, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Nashotah, write down the parcel ID from that panel; every clerk in the county will want it.
Reading the legal description
Wisconsin is laid out under the Public Land Survey System, so deeds around Chenequa reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Oconomowoc can be irregular. Write down the legal description for the tract near Chenequa when you talk to a surveyor.
Delafield, WI: the basics
Delafield is part of Waukesha County, Wisconsin, which means parcel data comes from the county. With a lot near Oconomowoc Lake, 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. Acreage past the town limits toward Wales usually falls under county rules rather than the town's.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor sets the real corners on land around Hartland. Owner names and values update on a schedule, so a recent sale near Oconomowoc Lake might lag behind.
Offices that can help
Questions about value or the owner field for land near Oconomowoc Lake belong with the county real property listing office, since that office keeps the assessment data. Building or septic questions for a lot near Chenequa go to planning, building or health offices, town or county, depending on location.
Two different maps
The tax map on the Waukesha County parcel viewer is a summary, whereas the plat carries surveyed dimensions.
Places you'll see on the map
Waukesha serves as the county seat, which is where the courthouse records live. Other places on the map include Nashotah, Hartland, Chenequa, and Oconomowoc Lake, where town lots give way to larger tracts. About 412,591 people call Waukesha County home (Census Bureau estimate, 2023) on roughly 550 square miles.
Recorded documents worth pulling
Before you sign anything, get the recorded deed through the Register of Deeds; the parcel map near Chenequa only summarizes it. Inherited tracts near Chenequa can sit on several deeds, so a title company can sort it out before a purchase.
When a plat changes
Lots near Oconomowoc can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations Lake show up in the records too.
Neighboring parcel maps
Waukesha County touches Dodge County, Jefferson County, Milwaukee County, Ozaukee County, and Racine County; every one of them runs a separate parcel map. Acreage along the edge near Oconomowoc Lake may be split in two county records, so check the adjacent map as well.
