Want to add a garage, run a home business or split a lot near River Falls? Your first check is the Hudson zoning map, because the district sets what's allowed. This town 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 for land near Baldwin.
Which office controls the Hudson zoning map
Inside town or city limits, the local government adopts its own zoning map, so a lot in this town follows that code around Glenwood City. Past the city line, around River Falls, county rules apply where they exist; ask the county planning office to be sure. The quickest way to tell which applies: look for a city limits layer in the St. Croix County Beacon site.
The viewer St. Croix County publishes
Property in and around North Hudson appear on the St. Croix County Beacon site, free to use and open without a login. For acreage around Roberts, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near River Falls, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Questions for the planning office
Have the parcel ID ready and describe the plan for the lot near River Falls; ask what's allowed by right and what needs a permit. Also ask whether the lot near Roberts is a legal lot of record, since some older splits don't.
Which office to call
If the acreage or value on a parcel near Roberts looks off belong with the county real property listing office, since that office keeps the assessment data. Building or septic questions for a lot near Hammond need the planning or permitting office, and the answer depends on jurisdiction.
How land is described here
Wisconsin follows the Public Land Survey System, which means a tract near North Hudson is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near River Falls vary in size. Keep the legal description for land near Hammond before you request a deed or survey.
Before you lean on the lines
Tax maps are drawn for assessment, not surveyed, so a fence near Somerset often sits a few yards off the line on screen. Near River Falls, records update in batches, so a deed recorded last month can take weeks to appear.
Hudson, WI: the basics
The town is part of St. Croix County, Wisconsin, and the county assessor maps its lots for land near Hammond. As the county seat, Hudson hosts the courthouse, handy when you need recorded documents. On ground around Somerset, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the town limits toward Hammond generally follows county rules instead.
How to look up the district
