Missouri contractor license requirements

Missouri regulates contracting through state licensing for specialty trades only, not general contracting. This page lays out exactly what Missouri requires: the licensing agency, who must be licensed, experience, exams, fees, the financial responsibility mechanism, and reciprocity, every figure sourced and dated below.

Who must be licensed in Missouri

Municipal and county building departments (the Office of Statewide Electrical Contractors licenses electricians) is the licensing authority. No statewide general contractor license; Kansas City, St. Louis (city and county), Springfield, Columbia, St. Charles County, and Jefferson City each run their own program.

This is an honest gap, not a coverage failure: Missouri genuinely does not run the kind of statewide general contractor competency system that states like California or Georgia do. See the national comparison for how Missouri stacks up against every other jurisdiction, and the do I need a contractor license guide for what that means in practice.

Experience and qualification

Set independently by each city or county; no statewide standard for general contracting.

Exam

No state exam for general contracting. Missouri does offer a single statewide electrical contractor license through the Office of Statewide Electrical Contractors, usable in any jurisdiction.

Financial responsibility

Missouri uses no bond or net worth requirement as its financial-responsibility mechanism. No statewide bond for general contracting; local jurisdictions set their own bonding and insurance rules.

Reciprocity and the NASCLA exam

Missouri is not on NASCLA’s participating-agencies list, confirmed directly against NASCLA’s own page, so a NASCLA Accredited Examination credential from another state does not by itself satisfy Missouri’s requirements. See contractor license reciprocity for what does carry over, and the 50-state comparison for which states do accept the NASCLA exam.
