STATE LICENSE
NoneSee what applies
No Missouri statute licenses concrete contractors. Local governments control the work: building permits for foundations and structural slabs, and right-of-way or driveway-approach permits for work touching public streets and sidewalks. Kansas City requires a business license and a contractor license before it issues permits.
State law still governs every pour. Construction employers with one or more employees must carry workers' compensation (RSMo § 287.030), an original contractor must give the § 429.012 notice to owner before receiving payment to keep mechanic's lien rights, and misrepresentation in a home improvement sale is an unlawful practice under the Merchandising Practices Act.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Missouri has no statewide contractor license for this trade, so the rules that matter are local: home-rule cities and charter counties set their own contractor licensing, business licensing and permit requirements. Kansas City, for example, requires a city business license, a Certificate of Qualification held by the trade supervisor, and a contractor license before it issues permits.
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.
Missouri issues no state concrete license, so the state-fee line is genuinely $0. Your costs are local licenses, permits and insurance.
Most Missouri employers need five employees before workers' compensation applies; construction employers need only one (RSMo § 287.030.1(3)).
Missouri's statutory notice to owner (RSMo § 429.012) must be delivered before you take any payment — without it you have no mechanic's lien.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
An employer who knowingly fails to insure its workers' compensation liability commits a crime and owes the state a separate money penalty; a repeat offense is a felony.
Giving the § 429.012 notice is a condition precedent to any mechanic's lien; omitting it with intent to defraud is a crime, and a fraudulent lien waiver or false affidavit is a felony.
Deception, false promises or misrepresentation in selling home improvement work is an unlawful practice; the Attorney General can seek injunctions, restitution and civil penalties, and willful fraud is a felony.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
