Missouri is a minimal-regulation state. Only electrical contractors are licensed at the state level (since July 2019). All other construction trades are not regulated by the state — local municipalities may have their own requirements. Highway work requires separate prequalification through the Missouri Department of Transportation.
Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.

Frequently asked questions

Pick the tab that matches your situation. Each FAQ gives a direct answer and points you to the full detail below.
No. Missouri does not license general contractors at the state level. Only electrical contractors are licensed statewide (since July 2019). All other trades — mechanical, plumbing, HVAC, general construction — are unregulated by the state. Check your local municipality for requirements. See Construction work regulated.
Apply to the Office of Statewide Electrical Contractors with a $200 non-refundable application fee, proof of experience (4,000-12,000 hours depending on education), a division-approved exam, and at least $500,000 in liability insurance from a Missouri-authorized insurer. See Requirements.
File a Contractor Questionnaire with the Missouri Highway and Transportation Commission. The questionnaire is valid for 12 months and takes about 2 weeks to process. You must be registered with the Missouri Secretary of State. For unlimited-cost projects (new contractors), your bonding company must certify willingness to bond projects over $2,000,000. See Requirements.
Missouri has only two state-level authorities: the Office of Statewide Electrical Contractors for electrical licensing, and MoDOT Construction and Materials for highway prequalification. All other trade licensing is handled at the local level. See Who regulates construction.
The application fee is $200 (non-refundable). You must also carry at least $500,000 in liability insurance. There is no specified license issuance or renewal fee beyond the application fee in the source material. See Requirements.
Missouri has no reciprocal agreements with other states. However, an exam previously passed in another jurisdiction may meet Missouri’s exam requirement if it appears on the division’s approved exam list. A local electrical license held for 6 of the previous 8 years also qualifies. See Reciprocal agreements.
Five paths: 12,000 hours (no degree), 10,000 hours (DOL apprenticeship), 8,000 hours (associate degree), 4,000 hours supervisory (EE degree), or 6 of the previous 8 years holding a local electrical license that required an NEC-based exam. See Requirements.
Not at the state level. Residential construction is unregulated by the state. Local municipalities may have their own licensing, bonding, or registration requirements. See Construction work regulated.
Not at the state level. Plumbing and HVAC are unregulated by the state. Check your local municipality for licensing requirements. These trades may require separate local permits and licenses. See Construction work regulated.

Special considerations

Different roles need different things from a Missouri page. Use the tab that matches your situation to see what matters most before you read the full detail below.
If your work is not electrical and not highway-related, Missouri does not regulate it at the state level. Check your local municipality for any licensing requirements.
  • Only electrical contractors are licensed at the state level (since July 2019).
  • All other trades — general, mechanical, plumbing, HVAC — are not state-regulated. Check local requirements.
  • Electrical applicants need at least $500,000 in liability insurance and must pass a division-approved exam.
  • Missouri offers multiple experience paths for electrical licensing, ranging from 4,000 to 12,000 hours depending on education.
  • Highway bidders must prequalify with MoDOT and be registered with the Missouri Secretary of State.
  • For unlimited-cost highway projects (new contractors), the bonding company must certify willingness to bond projects over $2,000,000.

Readiness checklist

Four things you need to confirm before you can treat Missouri as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.

Determine if state licensing applies

Missouri only licenses electrical contractors at the state level. For all other trades, check local municipality requirements. Highway work requires MoDOT prequalification.

Verify the experience path

For electrical licensing, confirm which experience path applies: 12,000 hours (no degree), 10,000 hours (DOL apprenticeship), 8,000 hours (associate degree), 4,000 hours (EE degree), or 6 years of local license. For highway, confirm $2,000,000 bonding capacity if seeking unlimited-cost prequalification.

Route to the correct office

Electrical licensing goes to the Office of Statewide Electrical Contractors. Highway prequalification goes to MoDOT Construction & Materials.

Confirm the requirement set

For electrical: confirm exam approval, $200 application fee, and $500,000 liability insurance. For highway: confirm questionnaire, Secretary of State registration, and bonding capacity.
If you can determine whether state licensing applies, verify the experience or prequalification path, and confirm the requirement set, you have the minimum package needed for a Missouri readiness check.

​
Construction work regulated

Missouri’s state-level regulation is narrow. Only electrical work and highway bidding have state gates. All other construction trades are unregulated at the state level.
Local municipalities may have their own licensing, bonding, or registration requirements for trades not regulated at the state level. Contractors holding a local electrical license for 6 of the previous 8 years may use that as an experience path for the state license.

​
Common determination scenarios

If you are trying to figure out where to start, expand the scenario that is closest to your situation.
Apply to the Office of Statewide Electrical Contractors with a $200 application fee, proof of experience (4,000-12,000 hours depending on education), a division-approved exam, and at least $500,000 in liability insurance. Missouri also accepts 6 years of a local electrical license as an experience path.
File a Contractor Questionnaire with the Missouri Highway and Transportation Commission. The questionnaire is valid for 12 months. Contractors must be registered with the Missouri Secretary of State. For unlimited-cost projects (no work with MoDOT in the past 5 years), you also need a certificate of insurance, bonding company letter for projects over $2,000,000, bonding company financials, and Secretary of State registration.
Missouri does not regulate these trades at the state level. Check with your local municipality for any licensing, bonding, or registration requirements that may apply.
Missouri has no reciprocal agreements with other states. However, an exam previously passed in another jurisdiction may meet Missouri’s exam requirement if it appears on the division’s approved exam list. Check the Office of Statewide Electrical Contractors website for the current list.

Reciprocal agreements
