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 — Mansfield Township'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.
