Adopted code

Village of Winnetka Community Development Department

Building permits in the Village of Winnetka, Illinois, in Cook County, are reviewed by the Village's Community Development Department, whose Building Permits and Construction pages sit on the Village's own site, at Village Hall, 510 Green Bay Road. The Illinois Capital Development Board says "The State has not adopted a building code for repairs to existing single family residences," so Winnetka's roofing rules are its own: the Village's Adopted Building Codes page lists the 2021 International Residential Code with Winnetka amendments for applications submitted on or after November 4, 2024. This listing covers the office's contact details, the Village's own statements on code and permits, and the rules state law sets for every Illinois roofer.

Registration details
  • state_level: Illinois licenses roofing contractors statewide with no dollar threshold. 225 ILCS 335/9(2): "No work involving the construction, reconstruction, alteration, maintenance, or repair of any kind of roofing or waterproofing may be done except by a roofing contractor or a qualifying party licensed or credentialed under this Act." Under 225 ILCS 335/5(a-3), "A municipality or a county that requires a building permit may not issue a building permit to a roofing contractor unless that contractor has provided sufficient proof of current licensure as a roofing contractor by the State," and a holder of a limited license is restricted to permits for work on residential properties of 8 units or less. The Illinois Department of Financial and Professional Regulation lists "Roofing Contractor, Licensed" among the professions it licenses.
Adopted code
THE 2021 INTERNATIONAL RESIDENTIAL CODE WITH WINNETKA AMENDMENTS, PER THE VILLAGE'S OWN ADOPTED BUILDING CODES PAGE. The page says "All building and fire safety permit applications submitted on or after November 4, 2024 will be reviewed for compliance with newly-adopted model codes," and under "Adopted Model Building Codes with Local Amendments (effective November 4, 2024)" lists the "2021 International Residential Code (IRC) for One- and Two-Family Dwellings - Winnetka Amendments," with added appendices including "2021 IRC Appendix AJ : Existing Buildings and Structures," and the 2021 International Existing Building Code with Winnetka amendments. It also says "Effective January 1, 2026 - The Village of Winnetka will be reviewing permits under the 2024 Illinois Energy Conservation Code," and that "it is important to cross reference the linked model codes with the Village's local amendments for an accurate picture of the Village of Winnetka's building codes." The amendments are codified in the Village Code on a third-party code library, which this record did not read, so it does not state whether the Village has amended the IRC's roof provisions.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Winnetka job address. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor "does not incur Retailers' Occupation Tax liability as to receipts from labor furnished and tangible personal property (materials and fixtures) incorporated into a structure," but "incurs Use Tax on the cost price of the tangible personal property that is incorporated into real estate," with "roofing materials" named in the rule's own list of examples. Repair and replacement are taxed identically: 130.1940(a)(3) defines "construct" to include "repair, renovate or remodel." The Illinois Department of Revenue states the Use Tax rate as "6.25% of the purchase price or fair market value, whichever is greater." Where the contractor buys for resale, the local tax follows "the place of business at or from which the contractor or builder handles the transaction" (130.2075(b)(3)), so the combined rate on materials is the supply house's or the contractor's, which this record does not pin down. The authoritative lookup is the Illinois Department of Revenue's MyTax Illinois Tax Rate Finder.
