Iowa County, Wisconsin Building Permit Guide

Outside its cities and villages, Iowa County requires a county permit from the Office of Planning and Development, 222 North Iowa Street, Suite 1223, Dodgeville (608-935-0333), for almost any construction or structural alteration; Scott Godfrey is the Planning and Development Director. County zoning is in force in all 14 towns. The county does not hold state dwelling code delegation: every town, village and city is delegated itself, so the building permit and inspections for a new house come from the local inspector, after the county permits.

What requires a county permit in Iowa County?

The county’s permit packet puts it plainly: a permit is required for almost any construction of or alteration to a structure outside a village or city, and a county permit is required even where the town has its own building permit. Under Section 2.3 of the zoning ordinance, no building, sign or other structure may be built, placed or enlarged, and no building’s use changed, without a county zoning permit.

What the county decides and what the state holds

The county zones the towns (all 14 adopted county zoning by 1980), regulates shoreland, floodplain and airport areas, permits septic systems and runs land division review, nonmetallic mining, manure storage and wind and tower siting. Cities and villages are outside county zoning. Construction standards for houses and commercial buildings are state codes; DSPS’s UDC delegated-agent list, current as of September 24, 2026, shows no county delegation, so the dwelling code is enforced by each municipality’s inspector. The county packet itself says local permits may be required under the Uniform Dwelling Code and asks owners to check.

Iowa County building department: who handles permitting

The Office of Planning and Development receives applications and issues building and zoning permits under the county ordinance, plus sign, land use and conditional use permits, inspects permitted sites and enforces the ordinances. A sanitarian, who is also the assistant zoning administrator, handles septic permits. Rezonings and conditional uses go through the county’s Planning and Zoning Committee with town input, and variances and appeals through the Board of Adjustment.

Iowa County permit types

One application packet covers the county zoning permit, the airport-affected permit and the shoreland and floodplain permits. The application asks for the footprint, height and approximate value, distances to lot lines, the road centerline, other buildings and the septic system, a plot plan (an aerial photo works best, and the office can supply one) and a labeled floor plan.

Residential permits

• New houses need, in order, the town’s driveway approval, a county sanitary permit, a town official’s signature confirming the building site, then the county zoning permit and an address number. The town’s own building permit and UDC inspections follow.
• Additions and accessory buildings are priced by footprint; only non-residential buildings of 100 square feet or less are exempt.
• Decks, pools and bins count as structures that are not buildings ($150).
• Anything with plumbing or a water connection, even an accessory building, needs a sanitary permit first.

Commercial permits

Commercial and business buildings in the towns take the same county zoning permit by footprint, and many uses need a rezoning or conditional use permit first. The land use change application ($750) is due by the first Friday of the month and must carry a written recommendation from the affected Town Board, because every town has an adopted comprehensive plan the county must follow. A rezoning is heard by the Planning and Zoning Committee and takes effect only after the County Board acts, usually the following month; no construction permit can issue before then. A conditional use needs only the committee’s action. Wind energy systems, mobile towers, manure storage facilities and nonmetallic mines have their own county permits and ordinances. Building plan review for commercial buildings is a state matter (DSPS or a delegated municipality), not the county’s.

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

What comes before the building permit

• Pre-application talk. The county asks applicants to discuss every project with its staff first to find zoning, subdivision or site issues.
• Driveway. The Town Board approves new driveways, or existing ones newly serving open land, before the county permit; county and state highway accesses may also need Highway Department or WisDOT approval.
• Sanitary permit. No zoning permit is issued for a structure with plumbing until the sanitary permit is issued.
• Shoreland and floodplain. Shoreland and floodplain permits cost $200 each, or $500 with a special exception and public hearing.
• Land division. Creating a lot under 40 acres, whether sold or kept, generally needs a certified survey map reviewed under the county subdivision ordinance.
• Road setbacks. Buildings must sit 110 feet from the centerline of a state or federal highway (50 feet from the right-of-way), 75 feet from a county trunk highway (42 feet) and 63 feet from a town road (30 feet), unless the district’s yard rule is larger.

Iowa County permit costs and fees

Zoning permit fees are printed in the county’s Zoning, Floodplain and Shoreland Permit Application Packet, with checks payable to Iowa County Planning. The fee depends on the footprint of the structure or use, not its value.

Worked example from the packet: a new house with a 1,800-square-foot footprint pays $250 for the zoning permit and $75 for the address sign, or $325, before the sanitary permit and the town’s building permit. After-the-fact penalties follow the property owner, not the parcel, and each offense is cleared after 36 months without another. Owners rebuilding after a natural disaster may ask the Planning and Zoning Committee to reduce or waive the fee. Sanitary permit fees are set by County Board resolution; ask the sanitarian for the current amount.

Trade permits and who may pull them

The county does not issue electrical, plumbing or HVAC permits; inspection of houses and their systems under the dwelling code is done by the municipality’s delegated inspector. The county’s trade role is the septic system:

• Sanitary permit: filed on the state sanitary permit application and signed by the licensed master plumber who takes responsibility for the installation; renewals, revisions, plumber changes and transfers go through the plumber.
• Contractor lists: the county posts a list of certified soil testers, plumbers and pumpers.
• Privies: need their own county sanitary permit and agreement.
• Permit life: under the county sanitary ordinance, a sanitary permit for a system not yet installed and approved expires two years after issue; the plumber can renew it for another two years before it lapses, and an expired permit must be replaced before work starts.
• Maintenance: every septic tank must be visually inspected and pumped within three years of installation or inclusion in the county inventory and at least every three years after that, unless the tank is found less than one-third full of sludge and scum; pumping is done by a certified septage servicing operator. In its 2025 cycle the county sent 1,517 maintenance notices and issued 217 citations, and its annual report counts 7,460 sanitary permits issued since the program began and about 4,890 active private systems.

For a new house, the state Dwelling Contractor certification and the state electrician and plumber licenses apply and are checked by the local building inspector, not the county.

How to apply for permits in Iowa County

Review, corrections and what causes delay

Under Section 2.3 the county must grant or deny a complete application in writing within 30 days. The packet says missing information is the most common reason for denial and delay. A permit lasts 24 months with no extension; after that a new permit is needed to continue. Starting before the permit is a citable violation: work must stop, a late permit with penalty fees must be sought, and if it cannot be issued the site must be restored.

Inspections in Iowa County

The county inspects each permitted project for compliance with the application and its approved use, and no new or altered building may be occupied until the county issues a Certificate of Compliance. It is the applicant’s job to notify the office when the project is ready for that inspection. Septic systems are inspected under the sanitary permit: the plumber in charge gives notice for the final inspection and arranges access, the system stays open until the county has inspected and accepted it, and a reinspection fee applies when a recheck is needed.

Footing, framing, electrical, plumbing and final inspections under the dwelling code are done by the town, village or city inspector who issued the building permit.

Wisconsin building code in Iowa County

Iowa County has no UDC delegation; every municipality in the county enforces the dwelling code itself. FEMA’s Community Status Book lists Iowa County (community 550522) as participating in the National Flood Insurance Program, with flood maps effective December 16, 2015, and the county floodplain ordinance (400.03A, 2023) covers mapped Zone A areas in the towns. The county reported no ordinance revisions in 2025.

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

Iowa County permit search and official resources

The zoning ordinance requires the office to keep a record of all permits for public inspection; ask Planning and Development at 608-935-0333 for a parcel’s permit, sanitary or zoning history.

Iowa County permit FAQs

Does Iowa County issue building permits?

It issues county zoning permits, which its ordinance also calls building permits, for nearly all construction in the towns. The state dwelling code permit and inspections come from the town, village or city inspector.

Do I need a county permit if my town issues a building permit?

Yes. The county permit is required regardless of any town permit, and it controls whether, where and how a structure may be built and used.

How much is a county permit for a new house?

It depends on the footprint: $150 up to 999 square feet, $250 to 1,999 and $350 to 4,999, plus $75 for an address sign.

Does a small shed need a permit?

Not if it is a non-residential accessory structure of 100 square feet or less; larger ones need a zoning permit.

How long is a county permit valid?

24 months from issue, with no extension; a new permit is needed to finish after that.

What happens if I build first and apply later?

The permit costs three times the normal fee for a first offense, four times for a second, and a third brings a citation as well.

Does county zoning apply in Dodgeville or Mineral Point?

No. Cities and villages have their own zoning, and the county has no zoning jurisdiction there.
