The City's Building & Code Enforcement page says "The Department issues residential and commercial construction-related permits and perform on-site inspections." The City's permit page lists a residential updates permit with a fee that varies. The pages this record read do not say whether a roof replacement alone requires a permit.

THE 2021 INTERNATIONAL RESIDENTIAL CODE, PER THE CITY'S OWN CURRENT BUILDING CODES PAGE. The page lists "2021 International Residential Code" along with the 2021 International Building Code, the 2021 International Existing Building Code and the "2015 International Energy Conservation Code." It does not cite the adopting ordinance. The City's Municipal Code is hosted on a code publisher's site that this record did not read, so it does not state which ordinance adopted these editions or whether the City has amended the IRC's roof provisions. 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."

Missouri taxes the roofer on materials, not the homeowner on the job, and the combined rate is not keyed to the Dardenne Prairie 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.
