How to get licensed as a contractor in Missouri
Missouri issues no statewide general contractor license and, unusually, no mandatory statewide trade licenses either. Licensing lives with cities and counties: St. Louis requires its graduated business license for contractors, Kansas City licenses residential contractors through its planning and development department, and the suburbs each do their own thing. The one statewide credential is optional but useful: the statewide electrical contractor license through the Division of Professional Registration, which municipalities must recognize.

When a license is required
There is no statewide licensing threshold because there is no statewide contractor license. Each city and county sets its own registration rules and any dollar lines, so the controlling question is always which jurisdiction issues the permit. The statewide electrical contractor license is voluntary but accepted across Missouri municipalities.
License classes in Missouri
Local contractor licenses
St. Louis requires a graduated business license for contractors and subcontractors, Kansas City licenses residential contractors through the city, and most suburbs run registration programs with insurance and fees.
Statewide electrical contractor license
An optional state credential through the Division of Professional Registration that municipalities must honor, sparing electrical contractors a wallet full of city licenses.
Local trade licenses
Plumbing, mechanical, and electrical journeyman and master cards are issued by cities and counties, often via ICC exams, and portability between jurisdictions varies.
What you need before you apply
- Each jurisdiction's contractor license or registration before pulling permits there
- General liability insurance certificates naming the jurisdictions that require them
- Workers compensation coverage for employees
- ICC or local exam results where the city's program requires testing
- A registered business entity with the Missouri Secretary of State
- For electrical contractors: the optional statewide license, or each city's own credential
How to get licensed in Missouri
- List your permit jurisdictions. Metro St. Louis and metro Kansas City each contain dozens of municipalities with separate rules. Your licensing plan is the list of places you actually pull permits.
- Register where you work. File each city's contractor application with insurance and fees. St. Louis and Kansas City have the most formal programs; smaller towns may only want a certificate on file.
- Consider the statewide electrical license. If you are an electrical contractor, the state license through the Division of Professional Registration replaces city-by-city licensing, since municipalities must recognize it. It is the best licensing deal in Missouri.
- Verify trade card portability. Journeyman and master cards are local, and acceptance between cities is inconsistent. Where ICC exams are the standard, your scores travel better than the card does.
- Calendar the renewals. Every jurisdiction renews on its own cycle. Track them in one place so no expired registration blocks an inspection.
Reciprocity with other states
There is no state GC license to reciprocate, and recognition between Missouri municipalities is decided city by city, with ICC exam scores being the most portable evidence. The statewide electrical license is itself the portability fix on the electrical side, since municipalities must accept it.
Working without a license
Penalties are local: municipal citations, stop-work orders, permit refusal, and fines under city ordinances, which in the metro areas are enforced through the permit system itself. Unlicensed electrical work in cities with licensing programs draws the same treatment. Verify each city's current requirements with its building department before bidding there.
Frequently asked questions
Does Missouri have a state contractor license?
No mandatory one. General contracting is licensed by cities and counties, and the only statewide credential is the optional electrical contractor license through the Division of Professional Registration, which municipalities are required to recognize. Everything else is local.
What do St. Louis and Kansas City require?
The City of St. Louis requires contractors and subcontractors to hold its graduated business license, and Kansas City licenses residential contractors through its planning and development department. The surrounding suburbs each maintain separate registration programs. Working across a metro means multiple registrations.
Do handymen need a license in Missouri?
Not from the state. Whether local registration applies depends on the city and whether the work needs a permit; non-permitted repair work is generally unregulated. Check the building department where the job sits, since metro suburbs differ street by street.
Is the Missouri statewide electrical license worth it?
For electrical contractors working in more than one municipality, almost always. Cities must recognize the state license, which replaces a stack of separate city licenses and renewals. Single-city shops can stick with their local credential if it is cheaper.
