Free site visits and estimates are available.
Keep historic review and building review as separate questions
For a Naperville association or owner, first establish whether the property has a historic designation. If it does, resolve the applicable appearance review before setting the replacement direction. Then confirm the building-review requirements for the actual work. One answer should not be used as a substitute for the other.
For a larger replacement program, record windows and patio doors by participating residence, including prior work and any changed openings. For new construction, provide the project stage and planned scope instead of an existing-window inventory. These are different starting points even when the property types are similar.
What the local housing data tells an owner
CMAP’s community snapshot reports that 7.8% of Naperville housing units are in structures with 20 or more units and 41.2% are in housing built from 1990 through 2009, using 2020–2024 American Community Survey estimates. CMAP housing snapshot
These are estimates of housing units, not counts of apartment buildings or condo associations. Housing age does not establish window age or condition. Use the figures as context for planning; define your project from the property’s actual openings, records and needs.
A local check before scheduling work
Naperville identifies exempt, administrative and commission paths for historic-property review. Its guidance distinguishes a Certificate of Appropriateness question from a building-permit question. These historic rules concern designated properties, not every property in the city. Naperville historic district and landmark regulations

We provide supply and installation together. Our scope is full replacement and new installation, with phased projects reviewed individually. Standalone single-window or single-patio-door work is outside our scope, except that individual residents may participate in an association-coordinated program. A complete commercial storefront can be a single project. Repair-only work and customer-supplied installation are not offered.

Local permit resources for Naperville
The official links below explain the local requirements. For your Kedzie Windows project, our team handles the permit process on your behalf.
Permit authority: Building Permits. Official department contact and guidance.
Application starting point: Open permit applications by project type.
Municipal phone: 630-420-6100 option 2 · Municipal email: buildingpermits@naperville.il.us
Choose the project-specific application instructions rather than assuming every category uses the same portal. Describe any change in window or patio-door size, style or location when asking which route applies.
When confirming permit requirements, we provide the municipality with the property details and proposed scope, including any changes to openings or framing. For an association program, we explain whether the work covers one residence, several units or multiple buildings.
We prepare and submit the application, coordinate any owner or association authorization needed, communicate with the municipality and arrange required inspections through completion. The municipality determines the applicable requirements and approvals; our team manages the process for you.
Common questions
Do I need a permit to replace my windows in Naperville?
A permit is required when replacement changes a window’s size or style, or when a window is installed in a new location, according to Naperville’s building-permit guide. For an unchanged replacement, confirm the scope and property designation rather than assuming all work is covered by that statement. Historic approval and building-permit requirements are separate checks.

Do I need a permit to replace my patio door in Naperville?
A permit is required if replacement changes the patio door’s size or style, or adds a door in a new location, under Naperville’s published guide. A change between sliding and hinged arrangements should therefore be described explicitly for City review. Confirm the treatment of an unchanged replacement and any historic-property approval separately.
