Before you buy a lot near Belgium with a plan in mind, pull up the Port Washington zoning map early: the zoning district can make or break the plan. What this Port Washington guide covers: which office sets the rules for a lot, matching a lot to its zoning district, and the questions that save a wasted trip.
The Port Washington zoning map: start here
Within municipal limits, the local government adopts its own zoning map, which means a parcel in Port Washington follows that code. Outside those limits, near Cedarburg or Fredonia, the county's ordinance, if any, takes over; confirm with the county office. The quickest way to tell which applies: look for a city limits layer in the Ozaukee County parcel viewer.
The viewer Ozaukee County publishes
Go first to the Ozaukee County parcel viewer; it maps every tax parcel in the county, Cedarburg included. For property near Fredonia, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Closer to Cedarburg, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Port Washington, WI: the basics
The town sits in Ozaukee County, Wisconsin, so its parcels are on the county's map for land near Grafton. As the county seat, Port Washington hosts the courthouse, handy when you need recorded documents. For property near Grafton, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the town limits toward Fredonia generally answers to county rules instead.
Offices that can help
For assessment questions about property around Saukville are handled by the county real property listing office, which maintains the tax roll. Building or septic questions for a lot near Grafton are for the local planning and health departments, depending on whether the land is inside town limits.
Zoning is only step one
Once zoning clears a project near Belgium, a building permit is a separate step; septic or sewer and driveway access are often reviewed too.
Questions for the planning office
Have the parcel ID ready and describe the plan for the lot near Cedarburg; staff can point to the right section of the ordinance. Ask whether a parcel near Fredonia meets current minimum size, because nonconforming lots can carry limits.
What the map can't tell you
Acreage on the record is a tax-roll number; just a licensed surveyor sets the real lines on land around Grafton. On ground around Cedarburg, records update in batches, so a deed recorded last month can take weeks to appear.
Neighboring parcel maps
Ozaukee County meets Muskegon County, MI, Oceana County, MI, Milwaukee County, Sheboygan County, and Washington County; every one of them runs a separate parcel map. Ground near Belgium that runs to the line may show up in two county records, so check the adjacent map as well. Out toward Newburg, the Platbookmapper state page links every bordering county map across Wisconsin.
Finding a parcel's zoning district
Pull the parcel up on the Ozaukee County parcel viewer, note the parcel number, then compare it to the zoning map from the office covering Port Washington. For a tract near Cedarburg, 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 Cedarburg, each district lists what's allowed outright and what needs approval. For a parcel near Fredonia, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
Reading the legal description
Wisconsin uses the Public Land Survey System, which means a tract near Fredonia is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Saukville can be irregular. Copy the legal description from the record for the parcel near Belgium before you request a deed or survey.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Saukville, so load it before you lose signal. A printout of the tract near Newburg helps when you meet an owner or agent.
Asking for an exception
For a parcel near Grafton, expect an application, a fee, notice to neighbors and a public hearing.
