Before you buy a lot near North Hudson with a plan in mind, look at the River Falls zoning map early: the zoning district can make or break the plan. Covered here for River Falls: who controls zoning for a given parcel, how to match a parcel to its district, and when a variance or rezoning comes up.
Getting started with the River Falls zoning map
Within municipal limits, the town or city normally writes the zoning code, so a lot in River Falls follows that code. Outside those limits, near Hammond or North Hudson, the county's ordinance, if any, takes over; confirm with the county office. A fast way to settle it: check the municipal limits layer on the St. Croix County Beacon site.
Pulling up a parcel
Property in and around North Hudson can be looked up on the St. Croix County Beacon site, a viewer that needs no account. Closer to Roberts, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Roberts, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Places you'll see on the map
Hudson serves as the county seat, home to the main records offices. Other places on the map include Roberts, North Hudson, and Hammond, each with its own cluster of lots. About 96,763 people call St. Croix County home (Census Bureau estimate, 2023) across some 722 square miles. St. Croix County dates to 1849, which matters when you trace an old farm's title.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Roberts, though signal can drop in rural spots. A saved image of the lot near North Hudson and its lines helps when you meet an owner or agent.
Land on the county line
The county meets Washington County, MN, Barron County, Dunn County, Pierce County, and Polk County, and each of those keeps its own parcel map, especially near Hudson. A tract near the line by Baldwin can show up in two county records, so check the adjacent map too. For a home near Baldwin, our state page links every neighboring county map across Wisconsin.
Where River Falls fits in
River Falls sits in St. Croix County, Wisconsin, and the county assessor maps its lots. For land near Baldwin, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits near Baldwin generally follows county rules rather than the town's.
Questions for the planning office
Have the parcel ID ready and describe the plan for the lot near Hammond; ask what's allowed by right and what needs a permit. Ask whether a parcel near North Hudson meets current minimum size, since some older splits don't.
Matching a lot to the River Falls zoning map
Look up the lot on the St. Croix County Beacon site first, copy its parcel ID, and use it when you ask the planning office near North Hudson. Closer to North Hudson, 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
On ground around North Hudson, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. For acreage around Roberts, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
Asking for an exception
With a lot near Roberts, most of these involve time, so budget weeks or months before you close.
Legal descriptions in Wisconsin
Wisconsin uses the Public Land Survey System, so deeds around North Hudson reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Hammond odd-sized. Copy the legal description from the record for the parcel near Roberts before you request a deed or survey.
Permits after zoning
Once zoning clears a project near Baldwin, you still need building permits and inspections; health and road departments may weigh in on land near North Hudson.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
