Missouri does not have a single statewide “general contractor” license for handymen; most contractor licensing is handled at the city/county level, and state licensure is mainly for specific regulated trades (and some state credentials like asbestos/lead). In Clay (Clay County, MO), expect to need local business licensing (city and/or the city where you perform work) plus building permits for many projects—even if you are a handyman. There is no single statewide “handyman exemption threshold” like some states use; instead, limits typically come from local permit rules and trade-license boundaries.
