Additional Notes

Cahokia Heights was formed May 6, 2021 by the merger of Alorton, Cahokia, and Centreville, Illinois; this entry reflects the current, post-merger city government (official site cahokiaheightsil.us), not any predecessor town. The Code Enforcement Department (Director Robert Darnell) handles permitting, zoning, floodplain, and property-maintenance matters per the official site, though the direct /code-enforcement/ page link currently 404s on the city's own site (a broken/stale internal link) -- phone, email, and address above came from the official domain's main content. Some third-party sources cite an older '@cahokiaillinois.org' domain and a different phone/director name (pre-dating the merger or since changed); those were not used here as they could not be confirmed on the current official domain.

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 Cahokia Heights'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.
