Missouri deck builders work under the No statewide building code — local jurisdictions adopt independently. Cities use various editions of IBC/IRC ranging from 2006 to 2018.. Missouri has no statewide building code or general contractor license requirement. Building permits are administered entirely by local jurisdictions (cities and counties). Some cities require contractor licensing; many rural areas have no permit requirements. Specialty trades (electrical, plumbing) have state-level requirements. Licensing is handled by the No statewide general contractor licensing — local jurisdictions set requirements. State licenses specialty trades (electrical via Division of Professional Registration)., and homeowners can cross-check a contractor before hiring. On the exemption side: varies entirely by local jurisdiction. A Missouri-specific rule most homeowners miss: missouri has NO statewide building code and NO statewide general contractor licensing requirement. The Kansas City and St. Louis permit portals handle the bulk of Missouri deck permit submissions — if your project is in one of those cities, start there.
