Additional Notes

Building inspector per Oconto County's official 'UDC Inspectors Contracted by Towns in Oconto County' list (rev. 06/2026): Paul Hahn, phahn1@hotmail.com, 715-250-3233. HEDGE: the town's own website (townofunderhill.com) instead lists a 'Building Inspector' phone of (715) 526-2380 with no name given — this may be outdated, or for a different inspection type; the county document is used as primary since it is the more recent, itemized authoritative source per-township. Town Office (general/clerk): (920) 855-2942, fax (920) 855-6859, clerk@townofunderhill.wi.gov (decoded from the site's Cloudflare-protected contact link), 5597 Cardinal Road, Gillett, WI 54124.

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 Underhill'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.
