About Missouri contractor licensing

Missouri does not have one statewide general contractor board for ordinary residential construction. Homeowners often need to rely on local licensing or registration, especially in places like St. Louis and Kansas City, while using state professional licensing tools for the trades that are regulated at the state level.

How licensing works in Missouri

Missouri is largely local for general contractors. Major cities and counties may impose contractor licensing, registration, or competency requirements, while the state Division of Professional Registration is more relevant for certain professions and trade categories. For homeowners, that means a contractor's legitimacy can depend heavily on where the project is located. A company working lawfully in one municipality may still need separate approval in another.

What to verify in Missouri

Start with the city or county where your property sits and confirm whether the contractor must be locally licensed or registered. Use Missouri's state license search for any regulated trade professionals participating in the work. Check active status, expiration dates, and the exact legal entity name where records exist. In St. Louis and Kansas City areas, do not assume regional familiarity means the contractor is cleared in your specific jurisdiction.

State-specific tips

• › Ask your local permit office which contractor credentials they expect to see for your exact address.
• › For St. Louis County versus city projects, verify the jurisdiction first; the rules are not interchangeable.
• › If the remodel includes electrical or plumbing work, verify those trade credentials separately even when the GC is locally approved.
• › Keep the contractor's full legal name, not just the brand name, when you call a local licensing office.
• › If a Missouri contractor also works in Illinois or Kansas, confirm the Missouri approval separately for your municipality.
