Visit official lookupAbout 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.

Frequently Asked Questions
- Does Missouri require general contractors to be licensed statewide?
- No. Missouri has no statewide general contractor license or registration requirement. Licensing requirements for residential and commercial general contractors are set entirely at the local level — by cities and counties. The Missouri Merchandising Practices Act (Mo. Rev. Stat. §407.010 et seq.) provides the primary statewide consumer protection for homeowners dealing with contractor fraud or deceptive practices.
- How do I verify a contractor is legitimate in Missouri without a state license to check?
- Confirm the contractor is registered with the Missouri Secretary of State at sos.mo.gov. Ask whether they regularly pull permits in your local jurisdiction — permit history is your primary verification tool in a state without a GC license. Request current certificates of general liability insurance and workers' compensation and verify both with the issuing insurers. Check the Better Business Bureau at bbb.org and ask for references from recent Missouri projects.
- Are specialty trade contractors licensed in Missouri?
- Yes. Electrical contractors and electricians are licensed through the Missouri Division of Professional Registration (DPR) under Mo. Rev. Stat. §324 — verify at pr.mo.gov. Plumbing contractors are licensed through DPR under Mo. Rev. Stat. §341.010 et seq. HVAC contractors performing mechanical work may also require DPR licensing. Always verify specialty trade license status at pr.mo.gov before hiring subcontractors.
- Does my city or county require contractors to be licensed in Missouri?
- Many do. St. Louis requires contractor licensing through the St. Louis Building Division. Kansas City has its own contractor licensing requirements through the Development Services Department at kcmo.gov. Springfield and Columbia have active local contractor licensing or registration programs. Always contact your local building department before hiring — a contractor registered in Kansas City is not necessarily licensed in St. Louis or any other Missouri city.
- What insurance should I require from a contractor in Missouri?
- Require general liability insurance and workers' compensation insurance. Missouri has an important distinction for construction: employers in the construction industry with one or more employees must carry workers' compensation under Mo. Rev. Stat. §287.010 — a lower threshold than Missouri's general five-employee requirement. Without a statewide licensing board, insurance verification is critical — always request certificates and verify coverage is active with the insurer directly.
- Is a written contract required for home improvement work in Missouri?
- Missouri has no specific home improvement contract statute requiring written contracts for residential work. General Missouri contract law and the Missouri Merchandising Practices Act (§407.020) prohibit deceptive practices in consumer transactions including home improvement. Always insist on a detailed written contract regardless — include the full scope of work, materials, pricing, payment schedule, start and completion dates, and a clause requiring lien waivers at each payment milestone.
- What recourse do I have if a contractor does poor work or abandons my project in Missouri?
- File a complaint with the Missouri Attorney General under the Missouri Merchandising Practices Act (Mo. Rev. Stat. §407.025) at ago.mo.gov. The AG can seek civil penalties and restitution. You may also sue in Missouri small claims court (up to $5,000 in most circuits) or circuit court for larger amounts. If the contractor committed fraud — took payment and abandoned the project — contact local law enforcement, as Missouri contractor fraud may also implicate criminal statutes.
- Where do I find contractor requirements for my city or county in Missouri?
- Contact your local building department directly. St. Louis Building Division information is at stlouis-mo.gov; Kansas City's Development Services is at kcmo.gov; Springfield's building development services are at springfieldmo.gov; Columbia's building inspection is at como.gov. For rural areas, contact your county planning and zoning or county commission office. Missouri has no central directory of local contractor licensing requirements.
- How do mechanic's liens work in Missouri and how can I protect myself?
- Under Mo. Rev. Stat. §429.010 et seq., a contractor, subcontractor, laborer, or material supplier who is not paid can file a mechanic's lien against your property. In Missouri, a lien must be filed in the circuit court within six months of the last work or materials furnished. A sub or supplier the GC failed to pay can lien your home even if you paid the GC in full. Protect yourself by requiring signed lien waivers from the GC and all major subs and material suppliers at each payment stage.
