THE 2024 INTERNATIONAL RESIDENTIAL CODE, ADOPTED BY ORDINANCE NO. 25-019, IN FORCE FROM JANUARY 1, 2026. The City's Current Codes & Amendments page says "We currently follow," and lists "2024 International Residential Code for One & two Family Dwellings," "2024 International Existing Building Code" and "2024 International Property Maintenance Code." The City's code-change notice says "the Lockport City Council has adopted the 2024 ICC Building, Fire and Existing Building Codes" and that "This change will take effect on January 1, 2026." Ordinance No. 25-019, passed December 3, 2025 and hosted by the City as a scanned PDF, replaces Chapter 152 of the Lockport Code of Ordinances in its entirety; Section 152.01 adopts the International Residential Code for One- and Two-Family Dwellings, 2024 Edition, by reference. The residential amendments in Section 152.03 were read; the only roof-chapter amendment is to Section R903.2.1 (drip edge and gutters). That section's heading still reads as amendments to the 2015 International Residential Code, a carry-over from Ord. 20-001 of March 4, 2020. The rest of the ordinance was not read for hail or impact-resistance provisions.
