Additional Notes
This is the TOWN of Grafton (Ozaukee County), a distinct municipal government from the neighboring Village of Grafton (also Ozaukee County - see previous entry); each has its own separate building department, inspector, and contact info, confirmed independently. The Building Inspector keeps flexible office hours (2 days/week, varying) - call ahead. General Town Office: (262) 377-8500, Mon-Thu 8:30 AM-4:30 PM, Fri 8:30 AM-Noon (Oct-May only). Wisconsin DSPS's UDC-delegated list names Bonnie Bartel, Treasurer, as the administrator of record (262-377-8500, bbartel@townofgrafton.org) and Jason Katz as inspector but with a different phone (414-881-9141) than the one currently listed on the town's own site (414-702-9709, used here as it's the live/current source) - likely an updated cell number; both are noted as a hedge. Mailing address: PO Box 143, Grafton, WI 53024.
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 — Town of Grafton'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.
