Missouri Electrician License Requirements (2026)

Missouri does not issue a statewide electrician license. There is no Missouri state electrical board, no state journeyman or master credential, and no statewide examination. Electrical licensing is handled entirely at the municipal level. Kansas City (Code Compliance Division) operates the dominant program in the western half of the state, requiring a Master Electrician credential — built on 10,000 documented hours of practical experience — before issuing an Electrical Contractor business license. St. Louis County's Department of Public Works runs the dominant program in the eastern half, licensing Electrical Contractors and registering Journeyman and Master Electricians. The City of St. Louis Building Division issues separate electrical permits and registrations. A multi-city electrical contractor must hold credentials in each jurisdiction.

Both Kansas City Code Compliance and St. Louis County Public Works review each applicant individually. Felony convictions and prior license revocations in any state are grounds for denial.

Required Experience and Education

Reciprocity and License Transfer

The NASCLA Accredited Examination is not accepted by Missouri for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

Missouri has no state electrician credential, so traditional state-to-state reciprocity does not exist. Some Missouri cities will waive portions of the exam for applicants who hold a Master Electrician credential from another city or another state with substantially equivalent standards, but each application is evaluated case by case. There is no automatic reciprocity between Kansas City and St. Louis County.

Application Process, Step by Step

Decide which Missouri jurisdictions you will work in. No state license. Kansas City, St. Louis County, City of St. Louis, Springfield, and Columbia all run separate electrical programs.
Document 10,000 hours of practical electrical experience. Kansas City requires 10,000 verified hours under a Master Electrician. Track every employer, dates, and supervisor.
Pass the Kansas City Master Electrician examination. Score 75% or better on the 100-question exam covering the NEC, KCMO electrical amendments, and business and law.
Obtain the Kansas City Electrical Contractor business license. File the business license application with Master Electrician designation, $25,000 surety bond, general liability and workers' comp certificates.
Apply to St. Louis County Department of Public Works. Register as Journeyman if needed, then sit the St. Louis County Master Electrician exam and apply for the Electrical Contractor business license.
Add City of St. Louis electrical registration. File a separate registration with the St. Louis Building Division to pull electrical permits inside the city of St. Louis.
Maintain annual renewals in every jurisdiction. Kansas City and St. Louis County licenses are annual. Calendar them separately — lapses freeze permit pulls.

Frequent Application Errors

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Missouri Electrician application.

Looking for a state electrician license

Missouri has none. Applicants who keep searching for a state board waste weeks. Go straight to Kansas City Code Compliance or St. Louis County Public Works.

Underdocumenting the 10,000 hours

Kansas City requires verified hours under a Master Electrician. Informal hour estimates are rejected. Build the affidavit chain while you work, not after.

Skipping the surety bond

Kansas City requires a $25,000 surety bond for Electrical Contractor business licensure. Forgetting it stalls the application until the bond is filed.

Confusing City of St. Louis with St. Louis County

These are two different governments with two different programs. Working across the river also pulls in Illinois licensing entirely.

Letting the bond or insurance lapse

Kansas City and St. Louis County both freeze permit pulls the moment the bond or insurance certificate expires. Stack reminders well before expiration.

Questions Applicants Ask

Does Missouri have a state electrician license?

No. Missouri has no state electrician credential and no state electrical board. All electrician licensing is municipal — Kansas City, St. Louis County, City of St. Louis, Springfield, and other cities each run their own programs.

How many hours of experience does Kansas City require for a Master Electrician?

10,000 hours of documented practical electrical experience under a licensed Master Electrician — roughly five years of full-time work. The hours must be verified by supervising Master Electricians on the Kansas City Code Compliance affidavit.

Do I need a federal credential as well?

There is no federal electrician license. The federal EPA Section 608 certification is for HVAC refrigerant work, not electrical. Kansas City and St. Louis County credentials, plus OSHA 10 or 30 for jobsite safety, are typical.

Is there reciprocity between Kansas City and St. Louis County?

No automatic reciprocity. Each jurisdiction runs its own exam and credential process. Some cities will waive portions of the exam for applicants holding equivalent credentials, but the waiver is discretionary and case by case.

How often do Missouri municipal electrical licenses renew?

Annually in both Kansas City and St. Louis County. Renewals require current insurance, current bond (Kansas City), and the annual fee.
