Waukesha and the county around it
Waukesha sits in Waukesha County, Wisconsin, so its parcels are on the county's map. As the county seat, Waukesha hosts the courthouse, which puts the Register of Deeds close by. For property near New Berlin, 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 city limits toward New Berlin usually falls under county rules, not municipal ones.
Which office to call
If the acreage or value on a parcel near Delafield looks off are handled by the county real property listing office, since that office keeps the assessment data. Zoning, permits and septic questions near Pewaukee need the planning or permitting office, town or county, depending on location.
