Adopted code

City of Chillicothe Codes and Zoning Department

Building permits in the City of Chillicothe, Missouri, in Livingston County, are handled by the Codes and Zoning Department at City Hall, 715 Washington. Missouri leaves residential building codes to local adoption, so Chillicothe's roofing rules are its own. The City's Current Adopted Codes page lists the 2021 International Residential Code, and its building permit application says all contractors must be licensed with the City Clerk's Office. This listing covers the office's contact details, the City's own statements on code and permits, and the state's sales-tax treatment of roofing materials.

Registration details
  • state_level: Missouri has no statewide roofing contractor licence: the index of Chapter 324 of the Revised Statutes of Missouri, the chapter on occupations and professions, lists no section on roofing contractors. Any licence, registration or bond is set by the city or county.
  • city_level: The City's building permit application lists a roofing contractor line and says "All Contractors must be currently licensed with the Chillicothe City Clerk's Office." The City's Contractor Licensing Requirements page directs readers to "Visit the City Clerk to Find Contractor Licensing Regulations."
Adopted code
THE 2021 INTERNATIONAL RESIDENTIAL CODE, PER THE CITY'S OWN ADOPTED CODES PAGE. The City's Current Adopted Codes page, updated May 20, 2025, lists "2021 International Residential Code" and "2021 International Building Code," with the "2006 International Energy Conservation Code." The City's Code of Ordinances is hosted on a code publisher's site that this record did not read, so it does not state whether the City has amended the IRC's roof provisions or which ordinance adopted these editions. Missouri law leaves building codes to local adoption: RSMo 67.280 provides that a community "may adopt or repeal an ordinance which incorporates by reference the provisions of any code."
Sales & use tax
Missouri taxes the roofer on materials, not the homeowner on the job, and the combined rate is not keyed to the Chillicothe job address in this record. The Department of Revenue's Contractors Tax Matrix lists "Tangible personal property to be sold as an attachment to real property" as Taxable on purchases by contractors, so a roofing contractor pays sales or use tax on shingles and underlayment when buying them. The Department states that "The state use tax rate is 4.225%" and that "Cities and counties may impose an additional local use tax," with the amount due depending on "the combined (local and state) use tax rate in effect at the Missouri location where the tangible personal property is stored, used or consumed." The rate in effect at a given address, including any special district rates, is on the Department of Revenue's Sales and Use Tax Rate Chart, which this record does not reproduce.
