Before starting any concrete project, one of the first questions homeowners ask is: do I need a permit? The answer varies by municipality, but in most McHenry and Lake County towns, the answer is yes — for most significant concrete work.
At RCC Masonry & Concrete, we handle permits for our concrete services customers regularly. Here's what you need to know about concrete permits in Illinois.
When Is a Permit Required?
While specific requirements vary by municipality, here are the general rules across McHenry and Lake County:
Usually Requires a Permit
- • New driveway installation or full replacement
- • Patio construction over 200 sq ft (varies by town)
- • Sidewalk replacement along public right-of-way
- • Garage slab or foundation work
- • Retaining walls over 4 feet tall
- • Any work affecting public drainage
- • Commercial concrete projects
Usually Does NOT Require a Permit
- • Small patio pads under 200 sq ft (varies by town)
- • Concrete repair or resurfacing of existing surfaces
- • Stepping stone paths
- • Small garden retaining walls under 4 feet
- • Patching and crack repair
- • Sealing and cosmetic coating
The Permit Process in McHenry & Lake County
Here's what the typical permit process looks like:
- 1.Submit an application to your local building department with project details, property survey or plat, and a site plan showing the proposed work
- 2.Pay the permit fee (typically $50–$300 depending on project scope)
- 3.Wait for approval (usually 3–10 business days for standard residential projects)
- 4.Display the permit on-site during construction
- 5.Schedule required inspections (usually sub-base and final)
- 6.Receive final approval after passing all inspections
What Happens Without a Permit
Skipping a required permit might seem like a way to save time and money, but the consequences can be significant. Municipalities can issue stop-work orders mid-project, fine you $100–$500 or more per violation, and in worst cases, require you to tear out completed work. Beyond enforcement, unpermitted concrete work creates problems when selling your home — inspectors flag it, buyers negotiate lower prices, and title companies may require remediation.

Why Permits Matter Beyond Compliance
Permits aren't just bureaucratic hurdles — they serve a practical purpose. The inspection process ensures your contractor is building to code: proper concrete thickness, adequate sub-base, correct drainage slope, appropriate setbacks from property lines, and no interference with utility easements. These requirements exist because substandard concrete work causes drainage problems, trip hazards, and premature failure.
