Trade business resources for Missouri.

Missouri is notable for not requiring a statewide general contractor license; instead, contractor licensing is largely governed at the city and county level, meaning requirements vary significantly by municipality. A few specific trade licenses — most notably electrical work — are regulated at the state level through the Division of Professional Registration.

State licensing board

Missouri does not have a statewide license for general contractors or roofers — those trades are regulated by local jurisdictions (e.g., St. Louis, Kansas City, Springfield each have their own requirements). Electrical contractors and journeyman electricians are licensed statewide through the Missouri Division of Professional Registration under the State Board of Electroclinicians (Electrical). Plumbing is also primarily regulated at the local level, though some municipalities adopt state plumbing codes enforced locally. HVAC/mechanical contractors likewise fall under local jurisdiction in most cases. Because no single state threshold or dollar amount triggers a statewide GC or specialty contractor license in Missouri, contractors must check with the specific city or county where work is performed to determine local bonding, insurance, and licensing requirements.
