One of the first questions on every estimate: do I need a permit? For a concrete driveway in Will County the answer is almost always yes. For a patio it's usually yes once it's a real patio and not a 4x4 pad. Here's how it works in the four towns closest to our Lockport shop, then the general process. One thing up front: ZBL Concrete & Design pulls the permit on every job that needs one. You never deal with the building department. It's on the quote as its own line.
Short Answer: Driveways Yes, Patios Usually
Across Will and DuPage County, municipalities require a permit for: replacing or pouring a driveway, widening or extending a driveway, touching the apron or public sidewalk at the street (that's a right-of-way permit, and the village cares a lot about it), and in most towns a patio over a size threshold or one that changes how water drains off the lot. Walkways and stoops are hit and miss — some towns want a permit for anything with a footing.
Lockport. The City of Lockport requires a building permit for new and replacement driveways and for patios. Flatwork permits run about $50–$75 and review is typically a few business days outside of peak season. The inspector checks the base and forms before the pour and the finished slope at the apron. Lockport also enforces a maximum driveway width at the right-of-way, which matters if you want to widen.

New Lenox. The Village of New Lenox requires permits for driveways (including replacement) and for patios; the application wants a plat of survey with the work marked. Fees are in the $50–$100 range and review takes about a week. New Lenox is particular about drainage toward neighbors — a patio that pitches water onto the lot next door will get flagged — and about setbacks from side lot lines.

Homer Glen. Homer Glen requires permits for driveways and for most patios, and it is the strictest of the four on stormwater because of the lot sizes and the unsewered areas. Larger patios may need a grading plan showing water routed away from the house and any septic field. Fees run about $50–$75 for flatwork; review can take one to two weeks. Homer Glen's rolling lots also mean the inspector looks at retaining steps and anything close to a slope.
Homer Glen
Plainfield. The Village of Plainfield requires a permit for driveways and patios, and it requires a site inspection — the inspector wants to see the base and reinforcement before concrete goes in, so the pour gets scheduled around the inspection. Fees are roughly $75–$100. Review runs a week or two in spring. Plainfield also enforces driveway width limits in the right-of-way and has HOA overlays in several subdivisions (Grande Park, Clublands) that add their own approval.

Fees and thresholds above are typical ranges and change from year to year — we confirm the current figures with the village when we file. Elsewhere: Naperville ($75–$150, stricter stormwater review, two-week turnaround), Joliet ($50–$100, right-of-way permit for aprons), Downers Grove ($75–$150, stormwater site plan, parkway tree protection), Bolingbrook and Romeoville (driveway permits, patio thresholds vary). We handle all of them. If you want a town-specific read before the estimate, the Lockport, New Lenox, Homer Glen and Plainfield pages cover what we do in each.
Other Will & DuPage Towns
The process, start to finish: after you accept the quote, we prepare the application — a site plan with dimensions, setbacks, the connection to the street, and the drainage direction — and submit it with the fee. The village reviews it (days in winter, weeks in May). When it's issued, we schedule the pour; in towns with a pre-pour inspection, we call it in the day before. After the pour, a final inspection closes the permit. You get a copy for your records; it matters when you sell.
What the Permit Process Looks Like
Why we file in February and March for spring jobs: in winter, a permit comes back in a few days. In May, the same application sits for two to four weeks behind everyone else's deck and fence. A winter booking has its permit in hand before the ground thaws, which is a big part of why winter bookings pour first.
What we need from you to file: a copy of your plat of survey (it's in your closing documents; if you can't find it, the county recorder has it), the HOA approval if your subdivision requires one, and a signature on the permit application where the town wants the owner's. That's it. We draw the site plan, write the scope, pay the fee and pass it through on the invoice at cost.
What Happens If You Skip It
Skipping the permit is a bad trade. If the village catches unpermitted driveway work — and they do, especially at the apron — you can get a stop-work order, a fine, and in the worst case an order to remove it. Unpermitted work surfaces on the disclosure when you sell, and buyers' attorneys ask about it. The permit is usually under 1 percent of the project cost. That's why it's on every ZBL quote. For a driveway or patio in any of these towns, call or text (312) 721-0835 — and if you're booking for spring, now is when the permit gets filed.
