Source: Wisconsin Statewide Parcel Map (Wisconsin State Cartographer's Office) (sco.wisc.edu), each county's own parcel and tax roll data, compiled into one statewide layer. Waukesha County’s roll in this data carries little or no year built (under a quarter of its records), so that filter counts almost nothing here. There’s no single-family count here: Wisconsin's property class 1 is every residential parcel (houses, duplexes and condos alike), so its roll can't single out single-family homes. Wisconsin’s data here carries no homestead flag, so nothing here says whether the owner lives in the property.
