Roofing permits & building code in Union

Roofing permit and contractor-licensing rules in Union are set locally by City of Union - Engineering / Building Department. Missouri has no statewide roofing or general-contractor license, so licensing and registration are handled at the local level — always confirm the current requirements with the authority before starting work.

Adopted building code
The Engineering / Building Department states that "The City of Union has adopted the following codes:" and lists the "ICC International Residential Code - 2021 Edition" with the 2021 editions of the International Building, Existing Building, Plumbing, Mechanical, Fuel Gas, Property Maintenance and Energy Conservation Codes and the 2020 National Electrical Code. It refers readers to Chapter 500 of the Municipal Code for more detail. The text of Chapter 500, including any local amendments to the residential code, was not read.
Permit process
The City's permits page says the department is "responsible for the review of plans and issuance of building permits for all residential and commercial construction and remodeling projects within the City." It asks for a Building Permit Application with two sets of plans, a site plan, and "truss plans if there is roofing involved." The page does not say whether a roof replacement alone requires a permit.
