Ahead of any building plan near River Hills, pull up the Brown Deer zoning map before anything else: the zoning district can make or break the plan. What this Brown Deer guide covers: which office sets the rules for a lot, how to match a parcel to its district, and what to ask the planning staff.
Getting started with the Brown Deer zoning map
Within municipal limits, zoning usually comes from the municipality, so property inside Brown Deer answers to that map. Past the city line, around River Hills, county rules apply where they exist; confirm with the county office. The quickest way to tell which applies: ask whether the parcel near Shorewood is inside the boundary.
Opening the official parcel viewer
Go first to the Milwaukee County parcel viewer; it covers every tax parcel in the county, Wauwatosa included. On ground around River Hills, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Whitefish Bay, the record panel typically gives the owner of record, assessed acreage, a parcel ID and often a sale date.
Where Brown Deer fits in
Brown Deer sits in Milwaukee County, Wisconsin, and the county assessor maps its lots. For a tract near Shorewood, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits toward River Hills generally follows county rules instead.
When a parcel crosses a boundary
Milwaukee County touches Muskegon County, MI, Ottawa County, MI, Ozaukee County, Racine County, and Washington County, all with their own assessor records. Ground near Whitefish Bay that runs to the line may be split in two county records, so check the neighboring map as well. On ground around Whitefish Bay, the Platbookmapper state page lists every neighboring county map across Wisconsin.
What the map can't tell you
The acreage figure is a tax-roll number; only a licensed surveyor sets the real boundary for a parcel near River Hills. In and around Whitefish Bay, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Reading the legal description
Wisconsin uses the Public Land Survey System, which means a tract near Fox Point is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near River Hills odd-sized. Write down the legal description for the tract near Fox Point for any title or survey request.
How to look up the district
Pull the parcel up on the Milwaukee County parcel viewer, note the parcel number, and match it to the adopted zoning map. Out toward River Hills, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.
What the district controls
Near Whitefish Bay, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. In and around River Hills, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
