Do I need a permit for pavers, driveway, or hardscape in Downers Grove?
It depends. Whether pavers, driveway, or hardscape needs a permit in Downers Grove 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. Patios, driveways, and hardscape that add impervious surface can require a permit and stormwater review in Downers Grove under the Stormwater and Floodplain Ordinance. Confirm whether your project needs a permit with Community Development. Driveway and approach work in the public right of way may need separate Public Works approval.
