Vernon County, Wisconsin Building Permit Guide

Vernon County has no countywide zoning yet: its Zoning and Sanitation Department, at 318 Fairlane Drive in Viroqua (608-637-5270), enforces the floodplain, shoreland protection, private onsite wastewater and telecommunications ordinances while the Planning Commission drafts a comprehensive zoning ordinance. The county issues sanitary permits through licensed plumbers and land use permits for floodplain, shoreland and wetland sites; the town issues the site permit, and the town’s UDC inspector the building permit, which cannot issue before the sanitary permit.

What requires a county permit in Vernon County?

The county’s permits turn on two questions: is the parcel in a floodplain, shoreland, wetland or hydraulic shadow area, and will the building need a septic system? Its checklist starts with a map review by county staff, because only then can they say whether a land use permit applies.

Every structure or premises meant for people to live in or occupy, permanently or now and then, that is not on public sewer must have a permitted system. A privy is allowed only when the building has no plumbing at all; piping that is merely roughed in counts as plumbing. County maps also show potential shoreland protection zones along intermittent streams not yet reviewed for navigability; building within 75 feet of one means the Zoning Administrator first makes a navigability determination.

What the county decides and what the state holds

The county’s ordinances are the Floodplain Ordinance (Chapter 26), the Shoreland Protection Ordinance (Chapter 50, whose section 50-9.0 caps impervious surface), the Private Onsite Wastewater Treatment System Ordinance (Chapter 70) and the telecommunications tower siting ordinance (Chapter 62). Towns run their own site permits and may set stricter septic setbacks, and the county tells owners to check town codes. The Uniform Dwelling Code is enforced by the towns, villages and cities with state delegations; the county holds none, and commercial buildings go through state plan approval.

Vernon County building department: who handles permitting

Zoning and Sanitation, led by Zoning Administrator Matthew Albright, has a sanitation technician and a zoning technician and works with the Vernon County Planning Commission, which is writing the county’s first comprehensive zoning ordinance and is also reviewing the land division ordinance; the department’s page gives its meetings as the first Wednesday at 2 p.m., while its 2026 agendas show monthly meetings, most on the second Wednesday at 2 p.m.

Towns, villages and cities: who issues the home permit

The state’s list of Uniform Dwelling Code delegations, current as of September 24, 2026, has no County of Vernon entry and shows a delegation for all 21 towns, the three cities and every village but Genoa. Where an inspection agency is named it is General Engineering, for Viroqua, Westby, the Towns of Bergen, Forest, Greenwood and Hillsboro, and the Villages of Chaseburg and Stoddard. Populations are Census 2025 estimates.

Vernon County permit types and application documents

The county’s land use permit application covers floodway, floodplain, shoreland, wetland and hydraulic shadow sites. It needs the completed checklist, a list of existing and proposed structures with their sizes, the dates they were built and photographs, a site plan to scale (an aerial map, survey or hand drawing is accepted), cost estimates for labor and materials, the signed application, the fee, scheduled site visits before and after the work, and copies of other permits. Owners doing their own work still give estimates, valuing their own labor.

Residential permits

On a floodplain site the plan shows the lot’s elevation, the lowest floor and fill elevations, the regional flood elevation and data showing the project will not obstruct flow or raise the regional flood; an elevation certificate or a hydraulic and hydrologic study may be required, and the study is required for development in a Zone A or hydraulic shadow. On shoreland, an impervious surface report lists every roof, sidewalk, driveway and deck within 300 feet of the ordinary high-water mark. Applications go by mail or in person; email filing needs the department’s authorization, and nothing is reviewed until payment arrives.

Commercial permits

The same land use, sanitary and reconnect applications serve commercial sites, and the reconnect form has a public or commercial building option. New mobile service support structures and Class 1 collocations need a county conditional use permit. Building plan approval comes from the state.

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

What comes before the building permit

• Town verification. County staff complete a form saying what county zoning, if any, applies; it goes with the town permit applications.
• Soil and site evaluation. Done by a certified soil tester and recorded with the county; old perc tests are no longer valid, but a recorded evaluation stays valid while the tested area is undisturbed.
• Sanitary permit. Filed by the plumber; mound and at-grade designs need state approval first, about four to six weeks.
• Town site permit, driveway permit and fire number. From the town, using the sanitary permit number.
• DNR permits. For wetlands, creek crossings and bridges.
• Tiny homes. A permanent tiny home follows the house path; one used like an RV must be licensed and titled as an RV, with no stairs or decks.

Vernon County zoning and sanitary fees

The fee schedule now linked from the department’s forms page is the 2027 schedule (file name “Fee Schedule 2027 Proposed”), which the county’s Infrastructure Committee approved on August 11, 2026 to take effect in 2027. Until then, the table gives the amounts stated in the department’s own handouts, its FAQ and its 2025 privy brochure. Building permit fees are the town’s.

The privy brochure’s $250 is newer than the FAQ’s $200 for the same permit. The 2027 schedule also lists $300 to change plumbers, $250 for an unscheduled site visit, $500 for failing to notify the county of an installation and $200 for a wetland or navigability determination.

Trade permits and who may pull them

Only a plumber can apply for a Vernon County sanitary permit. The system is designed by a state-certified septic designer, a master plumber or a master plumber-restricted service, and the plumber signs the county reconnect form stating that the existing system complies with the county ordinance and state code. The department posts lists of plumbers, certified soil testers, surveyors and septic maintainers and pumpers.

• House trades. The county issues no electrical, plumbing or HVAC permits; ask the town’s UDC building inspector which trade permits a new home needs.
• Septic maintenance. Systems are inspected every three years by a licensed master plumber, a certified POWTS inspector, a certified septage servicing operator or a registered POWTS maintainer, and pumped when solids reach a third of the tank; holding tanks are inspected every year.
• Changing plumbers. Call the department first; a plan already approved by the state may have to be resubmitted under the new plumber.
• Builders. A contractor building a one- or two-family home needs the state Dwelling Contractor certification and a certified Dwelling Contractor Qualifier before the town can issue the permit; an owner-occupant is exempt.

How to apply for Vernon County permits

Review, corrections and what causes delay

The county has 30 days to review and issue a sanitary permit, and the 2027 fee schedule says to plan on at least three to seven business days for plan review. State review of a mound or at-grade design adds weeks: four to six by the county’s checklist, four to eight by its FAQ. Incomplete land use applications are returned, and a denial can only be appealed after a complete application has been formally denied; appeals to the Board of Adjustment are due within 30 days of the decision. Building in a dam’s hydraulic shadow or in a Zone A means a hydraulic and hydrologic study first.

Inspections and final approval in Vernon County

County staff try to attend every soil and site evaluation and every system installation; the soil tester and plumber book those appointments directly, at least 24 hours ahead, with 48 to 72 hours encouraged. Land use permits include site visits before and after the work. The building inspections and any occupancy permit for the house belong to the town’s UDC inspector.

A land use permit is valid for one year and becomes void if substantial work has not started; one extension may be requested before it expires. Holding tank, privy and non-plumbing affidavits must be recorded with the Register of Deeds before the sanitary permit is issued. Pump and inspection notices go out each spring: every three years for septic systems and every year for holding tanks.

Starting work before the county’s sanitary or land use permit is issued means an after-the-fact permit at twice the normal fee, and citations or other legal action may follow.

Wisconsin building code

FEMA’s Community Status Book lists Vernon County (community 550450) as participating in the National Flood Insurance Program, with a current effective flood map dated November 2, 2012. The department’s page announces a FEMA appeal period on proposed new flood insurance rate maps, without a closing date, and invites questions on them. Its FAQ says habitable buildings must have their lowest level at or above the flood protection elevation, two feet above the base flood elevation.

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

Vernon County permit FAQ

Does Vernon County have zoning?

It has floodplain, shoreland protection, septic and telecommunications ordinances, but no comprehensive zoning yet; the Planning Commission is drafting one.

Who issues the building permit for a house?

The town’s (or village’s or city’s) UDC inspector. In the Village of Genoa, which has no delegation, a DSPS-appointed inspector.

Can I get my building permit before the septic permit?

No. The county says the UDC inspector cannot legally issue the building permit until the sanitary permit is issued.

How much is a septic permit?

$500 in the department’s FAQ; the 2027 schedule the Infrastructure Committee approved in August 2026 raises it to $600.

No. A new soil and site evaluation must be done and recorded with the county before the sanitary permit.

How close to a stream can I build?

At least 75 feet from the ordinary high-water mark, driveways included, no taller than 35 feet, with at most 15% impervious surface within 300 feet of the water.

Can I use an outhouse?

Only if the building has no plumbing, and only a permitted vault-type privy; earthen pit privies are not allowed.
