Adopted code

City of Jefferson Building Regulations Division

Building permits in Jefferson City, Missouri, in Cole County, are handled by the Building Regulations Division of the City of Jefferson's Planning & Protective Services department. Missouri leaves residential building codes to local adoption, so Jefferson City's roofing rules are its own. The City's Current Code Adoption page lists the 2018 International Residential Code as adopted, as amended by the City's Code of Laws. This listing covers the office's contact details, the City's own statements on code and contractor licensing, 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 contractor licensing page says "All contractors performing work in Jefferson City must have a local license." It adds that electrical and plumbing contractors obtain trade licenses from the Building Regulations Division and that "All other contractors are directed to the Business License Division to obtain their business license." It does not name a roofing-specific licence.
Adopted code
THE 2018 INTERNATIONAL RESIDENTIAL CODE, PER THE CITY'S OWN CODE ADOPTION PAGE. The page says "The City of Jefferson has adopted the following codes, as amended by the City of Jefferson Code of Laws" and lists "2018 International Residential Code" along with the 2018 International Building Code and the 2018 International Existing Building Code. The page links to the adopting section of the Code of Laws for each code, which 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 the 2018 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 Jefferson City 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.
