Additional Notes

Confirmed via the City's own official site, cityoflockport.net -- disambiguated as the Illinois city in Will County (815 area code, IL ZIP 60441), not Lockport, NY or elsewhere. Building Official is Brian Pohlis. The city's official FAQ page stated at the time of this research that 'our online permitting system is currently unavailable while undergoing maintenance' -- the BS&A portal URL is included per the instruction to include uncertain data with hedges rather than omit it, but its live availability was not confirmed at time of writing and should be verified before relying on it.

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 — City of Lockport'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.
