Additional Notes

DSPS delegated-authority list (Aug 2026, line 134): City of Platteville is 'Delegated' with Municipality Contact Joe Carroll, Community Development Director, 608-348-9741, carrollj@platteville.org, and Inspector Josh Copsey (General Engineering Co. - Inspection), 608-742-2169, gec@generalengineering.net / jcopsey@generalengineering.net. City's own website confirms it transitioned building inspection services to General Engineering Company. This is the much larger municipality (home to UW-Platteville); do not confuse with the small separate Town of Platteville below, which has different contacts.

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 — City of Platteville'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.
