Summary
Operating as a concrete contractor in St. Louis requires both state and local licensing compliance. Missouri mandates contractor licensing for most concrete work over $3,000, requiring examination and annual renewal through the Division of Professional Registration. Additionally, the City of St. Louis requires its own contractor license with specific insurance requirements and biennial renewal. All concrete projects require building permits through the city's Building Division, with mandatory inspections at key stages of construction. Contractors must maintain appropriate insurance coverage including general liability, workers compensation, and often bonding for larger projects. The regulatory environment is moderately complex but well-established, with clear processes for licensing, permitting, and inspection. Success in the St. Louis concrete market requires staying current with both state and municipal requirements while maintaining proper insurance coverage and safety protocols.
License Requirements
Missouri requires concrete contractors to obtain a Residential Contractor License through the Missouri Division of Professional Registration for residential work over $3,000, or a Commercial Contractor License for commercial projects. The residential license requires passing a business and law exam, while commercial work requires both business/law and trade-specific exams. St. Louis City requires a separate City of St. Louis Contractor License through the Building Division. Applicants must provide proof of insurance, pass a background check, and pay applicable fees. Licenses must be renewed annually in Missouri and every two years in St. Louis City. Concrete work under $3,000 in residential settings may not require state licensing but still needs city permits.
Permit Requirements
All concrete work in St. Louis City requires building permits through the Building Division at City Hall (1520 Market Street). Permits are required for driveways, sidewalks, patios, foundations, and structural concrete work. Applications must include detailed plans, property surveys, and contractor licensing information. Typical processing time is 5-10 business days for standard concrete work. Permit fees range from $50-200 depending on project scope and square footage. Inspections are required at various stages including excavation, reinforcement placement, and final completion. Right-of-way permits may be needed for sidewalk work adjacent to public property through the Street Department.
Insurance Requirements
Missouri requires minimum general liability insurance of $50,000 per occurrence for licensed contractors. Workers' compensation insurance is mandatory for businesses with 5 or more employees, or any employee in construction trades. St. Louis City requires contractors to carry $100,000 minimum general liability and $100,000 property damage coverage. Many projects require additional umbrella coverage of $1-2 million. Contractors working on municipal projects must provide performance and payment bonds equal to 100% of contract value. All insurance policies must name the City of St. Louis as additional insured for city projects.
