Additional Notes

Per the township's official site (sylvantownshipmi.gov), applicants must first get a zoning permit from the Township Planning & Zoning office (Scott Pacheco, Zoning Supervisor, spacheco@sylvantownshipmi.gov, (734) 475-8890 ext. 113, 18027 Old US-12, Chelsea, MI 48118), then obtain the building permit itself from CACA, which serves Sylvan Township plus several other townships and the City of Chelsea.

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 — Sylvan 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.
