Additional Notes
As of January 1, 2026, new UDC building permits for the Town of Koshkonong are issued through the City of Fort Atkinson's Jedidiah Draeger, Director of Neighborhood and Building Services — confirmed as the UDC contact/inspector on DSPS's August 19, 2026 delegated-municipalities list. Permits issued before Jan 1, 2026 by the town's prior inspector(s) are still inspected by whoever originally issued them; contact the Town Office (920-563-4510, clerk@koshkonongwi.gov) for those older permits. Separately, DSPS's commercial-building-delegation list names a different commercial inspector, James DeLuca (Municipal Services), 262-210-1741, jdeluca63@gmail.com, likely for non-residential/commercial projects. Jefferson County zoning permits (920-674-7130) are required before a town building permit.
What You Need Before Applying for a Permit
Most building departments ask for the same core package before they'll issue a permit: a completed application naming the property owner and contractor, the contractor's state license number and proof of insurance (general liability, and workers' comp if employees are on the job), a notice of commencement or equivalent recorded filing for larger jobs where the state requires one, and scaled plans or a site plan for anything beyond minor repairs. Roofing, fence, pool, and solar permits typically have their own simplified checklists — Town of Koshkonong's department (above) can confirm exactly what applies to your project.
Why this matters for insurance: permit history is one of the first things an underwriter or adjuster checks. Unpermitted work — a finished basement, an added bedroom, a rebuilt roof — can complicate a claim or even void coverage for that portion of the loss, and it routinely surfaces during a home inspection. Pulling the right permit up front, and keeping the closed-permit record on file, protects both the property's value and its insurability at resale.
