Vilas County, Wisconsin Building Permit Guide

In Vilas County the Zoning & Planning Department, in the Courthouse at 330 Court Street, Eagle River (715-479-3620), requires a county zoning permit for every structure in the unincorporated county, decks, patios, sheds and buildings without foundations included, and permits and inspects every septic system in the county. It does not enforce the Uniform Dwelling Code or issue building or occupancy permits; the county page lists an inspection agency for each town and the city instead.

What needs a county permit in Vilas County?

County zoning reaches all unincorporated land except the parts of the Towns of Manitowish Waters and Presque Isle that lie more than 1,000 feet from a lake, pond or flowage and more than 300 feet from a river or stream. Inside that area the county’s answer to “do I need a permit for my structure?” is yes.

Separate county permits cover septic systems, floodplain land use, erosion control and mitigation, conditional uses, rezonings, non-metallic mines, wireless towers and tourist rooming houses.

What the county decides and what the state holds

The County Board’s General Zoning, Shoreland Zoning, Floodplain Zoning, Private Sewage System, Subdivision Control and Wireless Communications ordinances and Highway Setback Ordinance No. 18 set the local rules. The Towns of Arbor Vitae, Land o’ Lakes, Manitowish Waters, Presque Isle and St. Germain also have town zoning ordinances, and other towns may have stricter local rules, so a town permit may be needed as well. On the Lac du Flambeau reservation the Tribe may regulate a project. Building and commercial codes are the state’s, enforced through the municipalities’ agencies and DSPS.

Vilas County building department: who handles permitting

Zoning & Planning, headed by Zoning Administrator David Sadenwasser, has ten staff. Each town is assigned to a deputy zoning administrator who answers questions about properties there, and a sanitary section handles septic permits, inspections and maintenance cards. The department also supports the Board of Adjustment, which has five members and two alternates and meets on the third Thursday of the month. It is also the county’s planning agency: with the 15 municipalities it adopted the Vilas County Comprehensive Plan, revised in 2023, and since December 15, 2025 eligible agricultural producers may join the state Farmland Preservation Program, which needs a Farmland Preservation zoning overlay on the property, in exchange for state income tax credits.

Permits are available at the Courthouse or by mail. Inside the building, the Zoning Office is the first office on the right through the brown double doors past security, and the Sanitary Office the second.

Towns and the city: who issues the building permit

The county page names two inspection agencies for Uniform Dwelling Code permits: Baas Inspection Agency for the City of Eagle River and the Towns of Land o’ Lakes, Phelps and St. Germain, and RC Inspection Agency for the other 11 towns. The state’s delegation list, current as of September 24, 2026, shows the city and 12 towns as delegated but does not list Lac du Flambeau or Manitowish Waters; for those two, confirm with the town and the state’s Inspector Lookup Tool whether the agency acts for the town or as the state-appointed inspector. Populations are Census 2025 estimates.

Vilas County permit types and application documents

One county form, the Vilas County Zoning Permit Application, serves zoning permits, demolition permits and shoreland alteration permits; floodplain work uses a separate Floodplain Land Use Permit Application. The forms list also has an erosion control plan, an on-site inspection request, a mitigation agreement (some vegetative and stormwater mitigation agreements need an affidavit recorded with the Register of Deeds) and a documentation of zoning form.

Residential permits

A new home needs its septic permit issued before the zoning permit or the building permit; the system does not have to be installed yet, but a soil evaluation alone is not enough. A detached garage on a lot with a house may have a convenience bathroom served by a proper septic system; a garage on a lot without a house may not. Clearing trees on waterfront property is restricted, so the county asks owners to talk to their town’s deputy administrator first. Camping on an unimproved lot needs a code-compliant septic system even if the camper has tanks, town approval and a one-time zoning permit that does not expire.

Commercial permits

The county does not enforce the commercial building code. For buildings under 50,000 cubic feet, RC Inspection Agency handles commercial plan review in Arbor Vitae, Boulder Junction, Cloverland, Lincoln and Plum Lake, and DSPS in the other towns and the city; DSPS reviews every larger building. Many commercial buildings under 25,000 cubic feet are exempt from plan approval but not from the code, while theaters, sports facilities with bleachers, schools, hospitals, nursing homes, CBRFs, hotels and motels and multifamily buildings of more than three units always need it. The county still requires a zoning permit for site preparation or an early start, even with DSPS early-start approval, and the early start needs its sanitary permits.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Sanitary permit. Issued before zoning or building permits for a new home.
• County zoning permit. For the structure itself, and a shoreland alteration permit for grading, filling or tree cutting near water.
• Town zoning. In Arbor Vitae, Land o’ Lakes, Manitowish Waters, Presque Isle and St. Germain.
• Tribal review. Inside the Lac du Flambeau reservation.
• Demolition. A county demolition permit, and possibly DNR or Department of Health Services asbestos or lead permits.
• Digger’s Hotline. A call before any excavation.

Vilas County permit costs and fees

The department’s amounts are on its Zoning & Sanitary Fee Schedule, a PDF linked from every program page, and its web pages print just one figure, the same-day inspection fee. Call 715-479-3620 for the schedule or the fee for a specific permit, and file the fee with the application.

To avoid the $200 same-day charge, septic inspections must be called in to 715-479-3619 before 4:00 p.m. Central Time on the day before the installation, and the inspection is assured only once a staff member answers.

Trade permits and who may pull them

In Vilas County every septic system must be permitted and installed by a Wisconsin licensed plumber, and the state sanitary permit application must carry original signatures of a licensed master plumber or master plumber-restricted service. The county is the state’s agent for those permits and reviews plans itself for non-pressurized in-ground systems, holding tanks and tank replacements under 3,000 gallons a day; pressurized systems, mounds, individual site designs and larger commercial systems go to DSPS. The department posts lists of plumbers and certified soil testers (updated August 18, 2026) and of pumpers, inspectors and aerobic treatment unit maintainers (updated April 24, 2026).

• House trades. The county issues no electrical, plumbing or HVAC permits; ask the municipality’s UDC inspection agency which trade permits a new house needs.
• Older systems. The county no longer accepts EH 115 soil forms; a repair, alteration, tank replacement, subdivision, condominium or tourist rooming house on a system installed on an EH 115 needs a new soil boring.
• Builders. A contractor building a one- or two-family home needs the state Dwelling Contractor certification and a certified Dwelling Contractor Qualifier before the agency can issue the permit; an owner-occupant is exempt.

How to apply for Vilas County permits

Review, corrections and what causes delay

New homes stall most often on the septic step: no zoning or building permit is issued until the sanitary permit is, and that needs a licensed plumber’s application and, for mounds or pressurized systems, DSPS plan approval. Waterfront projects can also need a mitigation agreement or a recorded affidavit. Variances and appeals go to the Board of Adjustment, which meets on the third Thursday of the month, and conditional uses, such as every new non-metallic mine, go through public hearings.

Inspections in Vilas County

Every septic installation, non-plumbing system and reconnection is inspected before it is covered; mounds, at-grade and sand fill systems are inspected twice, once at the plowed layer before construction and again at the mechanical components before capping. Zoning inspections are requested on the county’s on-site inspection request form. Footing-to-final inspections of a house, and its occupancy permit, come from the municipality’s inspection agency, not the county.

Once a system is in use it joins the sanitary maintenance program: each of the county’s more than 24,000 septic systems must be pumped or inspected at least once every three years, seasonal homes included, and pumped when the tank is more than a third full of sludge and scum. Colored maintenance cards go out in April, with reminders in September, and the county issues citations to owners who do not comply. Aerobic treatment units also need annual reports.

A tourist rooming house needs an annual county permit that expires on January 31 of the following year, a Public Health Department license, and occupancy limited to two people per bedroom as listed on the sanitary permit. Rooming houses in the City of Eagle River and the non-shoreland parts of Manitowish Waters and Presque Isle need no county zoning permit.

Wisconsin building code

FEMA’s Community Status Book lists Vilas County (community 550605) as participating in the National Flood Insurance Program, with a current effective flood map dated June 5, 2012; the county’s Floodplain Zoning Ordinance and floodplain land use permit apply on unincorporated land.

Wisconsin's Uniform Dwelling Code covers one- and two-family homes. Its Commercial Building Code covers public buildings, workplaces and buildings of three or more units. Local ordinances must conform to both. Wisconsin rules
