Missouri does not have a single statewide “general contractor license” for handymen or home-improvement contractors; licensing is primarily handled locally (city/county building departments) and by state trade boards for certain regulated trades. In Weston (Platte County), you should expect (1) a City of Weston business license and (2) local permits/inspections for many building, electrical, plumbing, and mechanical jobs. Even without a state contractor license, you generally cannot perform regulated electrical/plumbing/HVAC work without the locally required credential(s) and permits.
