Do you need a license to be a carpenter in Missouri?
No. Missouri doesn't license carpenters as a trade. There is no statewide contractor license; cities and counties set their own rules.
Local only · By ChiselJobs Team · Updated
In short
Missouri does not license carpenters or contractors statewide, and it has no statewide building code. Counties and cities adopt their own codes and license contractors themselves, including St. Louis County, Kansas City and Springfield. That means requirements change from one jurisdiction to the next, so the first step on any job is the local building department. There is no state home improvement registration. Missouri has no state apprenticeship agency; programs register through the U.S. Department of Labor Office of Apprenticeship. Check the rules where each job is located before signing a contract.
