Summary
Operating as a concrete contractor in Marietta, Cobb County requires compliance with both Georgia state licensing requirements and local municipal regulations. Contractors must obtain appropriate state licensing through the Georgia State Licensing Board, maintain proper insurance coverage, and register their business locally with Cobb County. Most concrete projects require building permits through the City of Marietta Development Services Department, with mandatory inspections at key construction phases. The Marietta market offers strong opportunities for concrete contractors, with pricing that reflects the Atlanta metro area's robust construction economy.

License Requirements
Georgia requires concrete contractors to obtain a state contractor license through the Georgia State Licensing Board for Residential and General Contractors if working on projects over $2,500 or structural concrete work. For residential concrete work under $2,500, no state license is required, but contractors must register with the Secretary of State for business operation. Commercial concrete work typically requires a Commercial General Contractor license. Cobb County requires business license registration through their Revenue Department. Licensing exams cover business law, project management, and trade-specific knowledge. State licenses must be renewed every 2 years with continuing education requirements of 6 hours for residential and 5 hours for commercial contractors.
Permit Requirements
Concrete work in Marietta requires building permits through the City of Marietta Development Services Department for most projects including driveways, sidewalks, patios, foundations, and structural concrete. Simple concrete repairs under 30 square feet may be exempt. Permit applications require detailed plans, engineered drawings for structural work, contractor licensing information, and property surveys. Application fees typically range from $50-200 for residential concrete work, with commercial permits varying by project scope. Plan review takes 3-5 business days for residential and 7-14 days for commercial projects. Inspections are required at various stages including excavation, rebar placement, and final concrete placement.
Insurance Requirements
Georgia requires minimum general liability insurance of $300,000 for licensed contractors, though $1 million is recommended for concrete work due to structural risks. Workers' compensation insurance is mandatory for contractors with 3 or more employees, including part-time workers. Cobb County may require proof of insurance for business license renewal. Some projects require performance and payment bonds, particularly for commercial or municipal work. Commercial concrete contractors often need professional liability insurance and completed operations coverage. Auto insurance with commercial use coverage is required for contractor vehicles and equipment transport.
