STATE LICENSE
ConditionalOffice of Statewide Electrical Contractor…
Since 2017, the Office of Statewide Electrical Contractors (Division of Professional Registration) has issued a statewide license under RSMo §§ 324.900–324.945. Every political subdivision must accept it in place of a local electrical contractor license for doing the work and obtaining permits, and may not demand a local exam on top of it (§ 324.925.1). A city that refuses can lose local sales tax distributions until it complies (§ 324.925.2).
The license is not mandatory: a contractor working where no local license is required, or holding the local license where one is, needn't hold the statewide license (§ 324.920.4). To qualify, an applicant shows $500,000 of liability insurance, posts any bonds each political subdivision requires, passes an approved national exam, and documents 12,000 verifiable hours (or 10,000 with a DOL journeyman certificate, 8,000 with an associate's degree, or 4,000 supervising with an electrical engineering degree).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Local governments keep their own electrical licenses, codes, permits and inspections (§ 324.925.3), but must accept a statewide license in place of a local contractor license and may not require a statewide licensee to pass a local exam (§ 324.925.1). A locality's permitting authority can suspend a contractor's work for up to 30 days while forwarding a complaint to OSEC (§ 324.940.3). Political subdivisions without licensing authority before August 28, 2017 gained none from the statute (§ 324.925.4).
The local offices section below names the exact permit desk for every Missouri county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
No one is required to hold the statewide license, but it is the only credential every Missouri city and county must accept for permits (RSMo § 324.925.1).
OSEC's fee page lists a $100 triennial renewal and a $200 inactive renewal; the rule (20 CSR 2117-1.070) sets $200 renewal and $100 inactive. The rule governs.
A statewide licensee may represent only one company at a time, and a firm must employ one at a supervisory level (RSMo § 324.920.3).
A practical sequence for a new electrical contractor in Missouri. Actual agency processing times are noted in the ledger above.
Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Any person — including a corporate officer or partner who personally participates — who knowingly violates §§ 324.900–324.945 commits a misdemeanor.
After an Administrative Hearing Commission finding, the division may censure, impose probation up to five years, suspend up to three years, or revoke.
A local permitting authority may suspend a contractor's work in its jurisdiction while a complaint is forwarded to the division.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
Every fact in this file was checked against these official sources on October 2026.
Pending verification: Current OSEC fee amounts: the OSEC fee page ("Fees Effective June 30, 2019") lists a $100 triennial renewal and $200 inactive renewal, the reverse of 20 CSR 2117-1.070 ($200 / $100); no later fee amendment was located · The current list of OSEC-approved examinations (published on the OSEC site as a PDF, not retrieved) · Specific contractor-licensing requirements of St. Louis City, St. Louis County, Springfield and Columbia (not retrieved from those governments' sites) · Which Missouri cities and counties had electrical licensing authority before August 28, 2017 (§ 324.925.4)
