Additional Notes

This is a distinct, separate government from the Village of Addison in Lenawee County (confirmed different county - Oakland - and different official site). The township appears to operate under two domains, addisontownshipmi.gov (primary, used above) and addisontwp.org (also loads and lists the same building department contact info), both of which appear to be legitimate official domains for the same township. Building Department contact is Jamie Martel, ext. 212.

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 — Addison 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.
