Missouri Masonry Contractor License Requirements (2026)

Missouri has no state masonry contractor license. The Missouri Division of Professional Registration does not register or test masonry contractors. Local building departments license at the city level — most prominently Kansas City Development Services (Class A/B/C/D Building Contractor), St. Louis Building Division, and Springfield Building Development Services. Missouri prevailing wage applies to public projects under RSMo §290.210. This page documents the verified path including the Kansas City and St. Louis frameworks, OSHA silica enforcement, and TMS 402 / IBC Chapter 21 compliance.

Authority flows from Missouri home-rule charter cities under Mo. Const. art. VI §19 and §20, enforced through municipal building codes.. Missouri has no state contractor board. Licensing, testing, bonding, and enforcement are handled entirely by individual municipalities. Kansas City (Code Compliance Division, City Planning and Development Department) and St. Louis (Building Division, Department of Public Safety) are the two dominant licensing authorities, with Springfield, Columbia, Independence, and St. Louis County operating their own independent programs.

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Missouri Masonry application.

Multi-city license stacking

Working Kansas City, St. Louis, and Springfield simultaneously requires three independent licenses with different exam vendors.

Tornado wind detailing

Missouri tornado wind exposure (Joplin, Springfield) requires enhanced anchored veneer tie spacing per TMS 402; post-2011 Joplin lessons drive enforcement.
