Roofing in Columbia, Missouri

Required

THE 2018 INTERNATIONAL RESIDENTIAL CODE, ADOPTED BY CITY CODE CHAPTER 6, ARTICLE VI WITH A WRITTEN, SECTION-NUMBERED AMENDMENT LIST. Sec. 6-65: "The 2018 Edition of the International Residential Code for One- and Two-Family Dwellings, published by the International Code Council, Inc., including Appendices A, B, C, E, F, G, H, K, N, Q, R, S and U ... is hereby adopted by reference and made a part of the Code of Ordinances, City of Columbia, Missouri" (Ord. No. 22828, 6-6-16; Ord. No. 22920, 9-6-16; Ord. No. 24001, 9-3-19). The amendment list in Sec. 6-66 was read in full as codified through Ordinance No. 26252 (March 16, 2026): it revises administrative sections (enforcement by the director of community development, trade licensing, appeals, penalties), inserts the City's Table R301.2(1) values, deletes the fire sprinkler mandates in favor of a purchaser option, and amends smoke and carbon monoxide alarm, foundation, stud, rafter-tie, uplift-strap, mechanical, fuel gas, plumbing, electrical and radon provisions. IT DOES NOT TOUCH THE IRC'S ROOF-COVERING OR REROOFING SECTIONS. A 2024 code update is proposed and pending: the City's 2024 Code Adoption Project page, read October 2, 2026, says the City "is actively collecting public feedback on the proposed changes" before City Council adoption, refers to "the 2018 standards the City currently uses," and lists the residential document as "Proposed Amendments." As of that read the 2024 codes were at the public comment step, before City Council adoption, so the proposed amendments are not current law.
