Additional Notes
Confirmed via official township site (ontwatwp.org), which offers downloadable Building, Electrical, Mechanical, Plumbing, Zoning Compliance, Variance, Site Plan Review, Special Land Use, Subdivision, and Fence permit applications. Cass County's own official site (casscountymi.org/1652) confirms building/mechanical/electrical permits are administered at the local township/village/city level rather than by the county. New construction also requires well/septic permits from the Cass County Health Dept. and a driveway permit from the Cass County Road Commission. Office hours Mon-Fri 8am-2pm; board meets 2nd Monday, 6pm. Note: the domain ontwatownship.com (also surfaced in search results) failed to resolve/does not exist -- ontwatwp.org is the verified working official site.
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 — Ontwa 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.
