Roofing permits & building code in Oak Park

Roofing permit and contractor-licensing rules in Oak Park are set locally by Village of Oak Park Permits and Development Division. Illinois licenses roofing contractors at the state level: under the Roofing Industry Licensing Act (225 ILCS 335) no roofing work may be done except by a state-licensed roofing contractor or qualifying party, with a limited license for residential properties of 8 units or less and an unlimited license for everything else, and a city or county that requires a building permit may not issue one to a roofing contractor without proof of current state licensure, while some cities add their own contractor registration on top — always confirm the current requirements with the authority before starting work.

Adopted building code
THE 2024 I-CODES, INCLUDING THE 2024 INTERNATIONAL RESIDENTIAL CODE AND THE 2024 INTERNATIONAL EXISTING BUILDING CODE, FOR PERMITS APPLIED FOR AFTER JANUARY 1, 2026. The Village's Building Permits page: "On Sept. 16, 2025, the Village of Oak Park Board of Trustees adopted the 2024 I-Codes and 2023 NEC, which applies to all permits applied for after Jan. 1, 2026," listing the Residential Code and the Existing Building Code among them. The Village's ordinance amending Chapter 7, Article 2 of the Village Code amends Section 7-2-1 to read "The 2024 International Existing Building Code (IEBC), as published by the International Code Council, is hereby adopted by the Village by reference," deletes the IEBC's Chapter 1, Part 2 (administration and enforcement), and provides that "Administration and enforcement of this code shall be governed by applicable provisions of chapter 1 of the 2024 International Building Code, as amended and adopted by the Village." For a reroof, the Village's Roofing Guidelines (dated December 26, 2025) refer to "Chapter 8 & 9 of the 2024 IRC" and cite IRC sections 908.4, 908.5 and 908.6, while the Village's 2024 residential code presentation notes list "Section 102.7.1 - Additions, Alterations or Repairs / IEBC specifically called out." This record has not read the Village's codified local amendments to the 2024 IRC, so it does not state whether they touch the roof-assemblies chapter, and it publishes no layer limit or impact-rating answer on the base code.
