What Can a Handyman Do Without a License in Wentzville, Missouri?

In Missouri, there is no single statewide "general contractor" or "handyman" license; contractor licensing is primarily handled by cities/counties, while the State regulates only certain trades (especially electrical) and business/tax registration. In Wentzville (St. Charles County), you should expect a City business license and City-issued permits for many projects, and you must still use properly licensed trade professionals for electrical/plumbing/HVAC where required by law or local code. Missouri does not publish a statewide handyman dollar-threshold exemption because the state generally does not license general contractors statewide; instead, thresholds and registration rules (if any) are local.

The magic number in MO: $None. Jobs under $None (labor + materials combined) don't require a contractor license — you can take those as a handyman. Jobs at or above $None require a contractor license. Know your number, know your limit.
