Village of North Hudson, Wisconsin: building permits, zoning and septic

The Village of North Hudson, Wisconsin requires a building permit for a new home, including modular and manufactured home installations.1 North Hudson administers village zoning, while its contracted inspection agency takes building-permit applications and answers zoning questions.23 Private septic work goes through the St. Croix County Sanitary Program rather than the village building inspector.4

Does Village of North Hudson have zoning and minimum home sizes?

North Hudson has village zoning, including the RS, RA and RD one-family and two-family residence districts.28 In those districts, a one-family residence must have at least 1,000 square feet of floor area; a two-family residence must have at least 800 square feet per family.5 A tiny-home proposal therefore needs to satisfy the applicable dwelling standard rather than rely on a county minimum.5

For RS, RA and RD lots established before 1987, minimum lot areas are 10,000 square feet for a one-family residence and 12,000 square feet for a two-family residence; lots established after Ordinance No. 2-87 require 13,000 and 15,000 square feet respectively.9 Principal buildings in these districts have a maximum height of 35 feet, and accessory buildings have a maximum height of 18 feet.10 Ask the inspection agency to identify the parcel’s district and applicable setbacks before choosing a house plan.3

Do you need a building permit in Village of North Hudson, and who issues it?

New one- and two-family dwellings in North Hudson need a Wisconsin Uniform Dwelling Code building permit, including stick-built, modular and manufactured home installations.1 The village contracts with Tony Feuerhelm Inspection Agency for building inspection services; apply directly to the agency and pick up and pay for building permits there.3

North Hudson publishes building fees that vary by project type, valuation and the referenced Schedule A, so there is no single new-home fee to quote for every project.11 Required new-home inspections cover footings, foundation and reinforcement, rough work, insulation and final inspection; notify the inspector named on the UDC permit when work is ready.12 An owner who currently occupies or will occupy the home may take out the construction and erosion-control permits under Wisconsin’s owner-builder provision, but the provision still requires those permits.6

How do septic permits work inside Village of North Hudson?

For a North Hudson property using private sewage treatment, the St. Croix County Sanitary Program distinguishes a State Sanitary Permit for installation of a private onsite wastewater treatment system from a County Sanitary Permit for repair, reconnection or rejuvenation.13 The county also requires a County Sanitary Permit for installation of non-plumbing sanitation such as a privy or composting toilet.14

A sanitary permit for private sewage work must come before the local municipal building permit, and only a licensed plumber may submit the sanitary application.4 County staff conduct at least one inspection for work requiring a sanitary permit.15 Existing sanitary records can be viewed through the county’s Ascent Permit Management system.15 We could not confirm when North Hudson requires a new home to connect to public sewer instead; ask the village building inspection agency which utility approvals the proposed home needs.3

Can you live in an RV or tiny home in Village of North Hudson?

We could not confirm a North Hudson rule allowing residential RV occupancy, including living in an RV while building; ask the village’s contracted inspection agency about the specific parcel and proposed duration before relying on that arrangement.3 North Hudson has its own zoning, and incorporated villages enforce their own zoning codes rather than the county’s General Zoning rules.216

For a tiny home used as a one-family residence in RS, RA or RD, the village’s 1,000-square-foot minimum floor area is a concrete constraint.5 A modular or manufactured home installation also needs the UDC building permit.1 We could not confirm a separate tiny-home occupancy category or permission for an independent accessory dwelling; take the proposed use and floor plan to the inspection agency for a zoning answer.3

Building a home in Village of North Hudson: what are the steps?

Start with the North Hudson inspection agency to resolve building-code and zoning questions for the proposed home.3 Check the residential district’s floor-area and lot-area standards against the house and parcel before committing to the design.59

For private sewage treatment, have a licensed plumber submit the sanitary application to St. Croix County before obtaining the municipal building permit.4 Submit the UDC application with project, owner, contractor and location information plus the required plans or data, then obtain the building permit through the village’s inspection agency.173 Arrange the required construction inspections with the inspector listed on the UDC permit.12 Occupancy follows a final inspection with no major health or safety violations; ask the agency whether North Hudson also requires a separate occupancy document.183

What should you check before buying land in Village of North Hudson?

If a North Hudson project will use a new private well that is not high-capacity, Wisconsin requires advance DNR notification; some DNR-approved county ordinances also require a well permit.7 We could not confirm North Hudson’s additional private-well or public-water connection requirements; ask the inspection agency to identify the approvals for the proposed utility arrangement.3

Street or public-way excavation in North Hudson requires prior approval, a permit from the clerk, plans, insurance and a $10,000 indemnity bond.17 A new connection to a state trunk highway requires a WisDOT permit, with county highways and municipal roads potentially subject to different authorities.19

For land outside village limits, use the St. Croix County guide to distinguish county zoning from municipal zoning; incorporated villages enforce their own codes.16

Watch-outs

  • North Hudson’s RS, RA and RD minimum floor areas apply by dwelling type: 1,000 square feet for a one-family residence and 800 square feet per family for a two-family residence.5
  • A composting toilet does not bypass sanitary approval: St. Croix County requires a County Sanitary Permit for installation of non-plumbing sanitation.14
  • We could not confirm residential RV permission or village-specific setback requirements; ask the North Hudson inspection agency before buying for an RV or compact-home plan.3
