Additional Notes
This is the Village of Windsor in Mercer County, whose official name is legally 'Windsor' but which operates and is commonly known as 'New Windsor' (official site: newwindsoril.gov; do not confuse with the Village/Windsor Township in Shelby County, a separate entry). The official village site confirms Village Hall's phone, address, and limited office hours (Tuesdays 4:30-6:30 PM, Saturdays 9:30 AM-Noon) but does not describe a distinct building/zoning department or process. Mercer County's Zoning Department (100 SE 3rd St, Aledo, IL; 309-525-3799; enforcement officer Ron Fullerlove, rfullerlove@mercercountyil.org, confirmed via mercercountyil.org) handles unincorporated areas; whether it also administers permits inside village limits by agreement was not confirmed, so it is not listed as this village's authority. Treat the Village Hall contact as a starting point rather than a confirmed dedicated permit office.
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 — Village of Windsor'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.
