Building permits in Westmont, IL
In Westmont, permits go through the Community Development Department at Village Hall, and simple replacement jobs can qualify for a flat-fee permit. Here is how it works.
What needs a permit
- The Village asks you to check with its permitting staff before starting any project.
- Simple jobs like fences, replacing a driveway or patio, replacing windows and doors without structural changes, water heaters, HVAC and roof replacements have a $100 flat-fee permit plus inspections.
How to apply
- Submit the permit application with the Village's specification sheet for your project type. Small projects can be emailed.
- Depending on the work, include plans, a plat of survey and a site plan drawn to scale, and product specifications. Structural work may need plans sealed by a licensed architect or engineer.
- Contractors must be registered with the Village. A non-refundable application fee of 0.4% of the construction cost, at least $100, is due when you submit.
Review and inspections
- Express permits for flat-fee jobs (except fences) can be processed in about one business day.
- Request inspections by phone or email. They are booked for a morning or afternoon window, and staff call to confirm the time.
- Post the permit placard where it can be seen from the street.
