Do I need a permit for pavers, driveway, or hardscape in Unincorporated Will County?
It depends. Whether pavers, driveway, or hardscape needs a permit in Unincorporated Will County comes down to the details of your project.
Illinois has no statewide residential permit-exemption list, so whether flatwork such as a patio, walkway or driveway needs a permit is a local decision. Most Illinois jurisdictions do not require a building permit for at-grade paving, but many require zoning review for impervious-surface and lot-coverage limits. Most Illinois local codes require a permit for a retaining wall over 4 feet in height or for any wall supporting a surcharge. That 4 foot figure comes from the model residential code rather than from Illinois law, so confirm the height your jurisdiction uses and how it measures it. In Will County, permits outside the cities are handled by the Will County Land Use Department, Building Division, reachable on 815-727-8634 at https://willcounty.gov/County-Offices/Economic-Development/Will-County-Land-Use-Department. Its online permit portal is https://co-will-il.smartgovcommunity.com/Public/Home. This office permits the unincorporated parts of Will County. If your address sits inside a municipality, that municipality issues the permit instead. Patios are often exempt while driveway and right-of-way work is not, so confirm which side of that line your project falls on.
