Licensing
Do you need a license in Missouri?
Missouri has no statewide contractor license, but installation work can fall under local contractor or building-permit rules in cities and counties such as St. Louis and Kansas City, and a local business license is common. Because installation requirements vary by jurisdiction, verify current local and state rules before doing install work. A NISCR certificate is a professional credential, not a contractor license.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
