Do you need a permit for windows, roofing, or siding in DuPage County? A homeowner's guide to building permits.
One of the most common questions we get from DuPage County homeowners: do I need a permit for my project? Here's the straightforward answer.
Projects That Typically Require Permits
- Roof replacement — almost every municipality in DuPage County requires a roofing permit
- Siding replacement — most municipalities require a permit if you're replacing the entire exterior
- Window replacement — many municipalities require permits, especially if changing window sizes or adding/removing windows
- Entry door replacement — permits often required if changing the size of the opening
- Structural changes — any modification to load-bearing walls, headers, or framing always requires a permit
Projects That Usually Don't Need Permits
- Gutter replacement (like-for-like)
- Storm door installation
- Minor repairs (replacing a few shingles, fixing trim)
Why Permits Matter
Permits aren't just bureaucratic red tape — they ensure work is done to code and inspected by the municipality. Unpermitted work can cause problems when selling your home (buyers' inspectors look for this), void your homeowner's insurance coverage, and result in fines if discovered.
We Handle Permits for You
For every project that requires a permit, we pull it ourselves, schedule inspections, and ensure all work meets local building codes. You don't need to visit the building department or deal with paperwork. This is included as part of our service across every municipality we work in — Wheaton, Naperville, Glen Ellyn, Lombard, Elmhurst, and all 70+ communities we serve.
How the permit process usually goes
For most exterior work the contractor applies, not the homeowner. The application lists the scope and the contractor's registration and insurance. Simple re-roof and siding permits are often issued within days; projects that change openings or structure take longer. After the work, the town inspects. Rules and fees are set by each municipality, and unincorporated addresses go through the county, so the first step is always confirming who has jurisdiction over your address.
Why skipping a permit costs more
Work done without a required permit can be stopped mid-job, fined and ordered to be opened up for inspection. It can also surface years later when you sell and the buyer's attorney asks for permit history. A contractor who suggests skipping the permit to save time is shifting the risk to you. We check requirements before ordering and include the permit in the schedule.
Where exterior money goes furthest
For how a house looks from the street, the front door, garage door and siding color do the most. For comfort, windows and air sealing. For protecting the building, roof, gutters and flashing. For resale, national cost-versus-value surveys consistently put entry doors, siding and windows near the top for the share of cost recovered. A good plan fixes anything leaking first, then spends on what you will see and feel every day.
Plan the whole house, then phase it
Even if you will do one project a year, decide the end result first: roof color, siding color, trim and window finish. Then each phase fits the next and nothing has to be redone. Tell your contractor the full plan. We keep measurements, product lines and colors on file so that the windows installed next year match the ones installed this year.
A ten-minute walk around the house
Twice a year, walk the outside slowly. Look up at the roof edges for lifted shingles and sagging gutters. Look at the siding for cracks, gaps and soft spots near the ground. Check caulk around windows and doors. Look down at the foundation for soil that has settled toward the house and downspouts that have come loose. Photograph anything that has changed since last time. Small problems caught in a walk-around are cheap; the same problems found by a leak are not.
