Kedzie Windows supplies and installs windows, patio doors and complete commercial storefront systems in Mount Prospect. We work with apartment owners, condo associations, HOAs and property managers on replacement and new installation, including coordinated work around occupied residences. Free site visits and estimates are available.
Match the scope to the rental property’s unit records
A Mount Prospect rental-property inquiry should use the same unit references that the owner or manager uses to arrange access. List windows by unit and shared area, then add a separate patio-door count. Consistent identifiers reduce confusion when a resident report, an installation location and a management record refer to the same space.
If the building has had piecemeal replacements, identify those locations before planning a new phase. Describe changed openings separately from like-for-like locations. For a mixed-use property, keep storefront entrance work distinct so commercial access arrangements are not buried in the residential unit list.
What the local housing data tells an owner
CMAP’s community snapshot reports that 9.5% of Mount Prospect housing units are in structures with five to nine units and 48.2% are in housing built from 1940 through 1969, 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
Mount Prospect’s Community Development resources include building permits and inspections as well as rental housing and licensing. These are separate functions; a rental registration should not be treated as approval for proposed alteration work. Mount Prospect Community Development resources

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.

Common questions
Do I need a permit to replace my windows in Mount Prospect?
Confirm the permit requirement with Mount Prospect before scheduling replacement. Section 21.203 requires permits for building alterations and repairs, but the reviewed official resources do not clearly state a same-opening window exception. Give Community Development the property type, replacement scope and any framing changes so it can determine the applicable route.

Do I need a permit to replace my patio door in Mount Prospect?
Ask Community Development to classify the patio-door replacement under Mount Prospect’s building-permit requirements. The general code covers alterations and repairs; it does not provide a clearly verified patio-door exemption in the resources reviewed here. Specify whether the work replaces the door and frame within the opening or also changes the opening.
