When land near Hartland catches your eye, a look at the Delafield GIS map gives you lines, owner names and parcel numbers. In this Delafield guide: where that map lives, how to search it, and the limits worth knowing.
Opening the Delafield GIS map: start here
For a tract near Oconomowoc, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Your first stop is the Waukesha County parcel viewer; it covers each assessed parcel in the county, Chenequa included. For a parcel near Wales, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Oconomowoc, save the parcel ID from that panel; every clerk in the county asks for it first.
City limits and county records
Delafield sits in Waukesha County, Wisconsin, so its parcels are on the county's map. Out toward Hartland, 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 Nashotah often follows county rules rather than the town's.
Search tips
By address works best for lots in Delafield; for owner searches, try last name first. For a tract near Oconomowoc, a parcel ID is the most reliable search, and it's printed on tax bills.
Layers worth turning on
Closer to Chenequa, look in the layer list for municipal boundaries, floodplain and sometimes zoning; not every viewer has them all.
Which office to call
If the acreage or value on a parcel near Oconomowoc Lake looks off belong with the county real property listing office, since that office keeps the assessment data. Questions about what you can build around Nashotah need the planning or permitting office, and the answer depends on jurisdiction.
Printing and saving
Save a screenshot of the lot near Chenequa and its record panel, which helps later when you ask the assessor or a title company.
A quick look at the area
Waukesha is the county seat, where most land records are kept. You'll also find Nashotah, Hartland, Chenequa, and Oconomowoc Lake, each with its own cluster of lots. Roughly 412,591 people call Waukesha County home (Census Bureau estimate, 2023) across about 550 square miles.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Oconomowoc Lake often sits several feet off the line on screen. In and around Oconomowoc Lake, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Oconomowoc, but coverage can be spotty out of town. A saved image of the lot near Wales and its lines helps when you meet an owner or agent.
What the record panel tells you
The record for a parcel near Wales typically lists owner, mailing address, assessed value and acreage.
Backing up the map with records
For anything that matters, pull the recorded deed through the Register of Deeds; the parcel map near Nashotah only summarizes it. Long-held tracts around Oconomowoc Lake can trace back through many deeds, and a title company is worth hiring on a real sale.
Troubleshooting the viewer
When the map won't open around Chenequa, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Sections, lots and bearings
Wisconsin is laid out under the Public Land Survey System, so deeds around Oconomowoc reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Chenequa can be irregular. Copy the legal description from the record for the parcel near Nashotah for any title or survey request.
Next door to Waukesha County
Waukesha County meets 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 Nashotah can be split in two county records, so check the neighboring map too. Closer to Wales, the Platbookmapper state page links every bordering county map across Wisconsin.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
