Additional Notes

A legally distinct, separate government from the City of Sun Prairie above (both in Dane County) — do not confuse. Building inspection is contracted to General Engineering Company; inspector Jim (James) Trebian holds office hours Mondays 10-11am or by appointment. WI DSPS delegated list gives the municipal clerk contact as Kay Weisensel (608-837-6688) and the inspector contact as James Trebian, General Engineering-Insp, 608-742-2169, gec@generalengineering.net; the town's own website instead publishes Trebian's individual email jtrebian@generalengineering.net. Town office: 5556 Twin Lane Road, Marshall, WI 53559. Effective 7/1/2024, permits are no longer required for replacing water heaters, softeners, or furnaces/AC units.

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 Sun Prairie'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.
