Additional Notes
Confirmed via clinton-county.org/175/Planning-Zoning, which explicitly lists Duplain as one of the ten General Law Townships served by the county's Planning & Zoning Department; the county Building Department serves the same set of General Law Townships for building/electrical/plumbing/mechanical permits. Duplain Township's own site (duplaintwp.com) had a certificate/hostname mismatch and could not be verified directly, so its own contact info (145 W Main St, Elsie, MI, phone possibly (517) 862-4430 per a third-party directory) is left out of certHolder fields as unconfirmed on an official source. Online BS&A permits limited to roofing/siding/window-door(3+) projects; other permit types require contacting the county directly. Inspection line: 989-224-5183.
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 — Duplain 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.
