Next Steps to Launch Your General Contracting Business
- 1
Form your LLC or corporation in Missouri — general contractors carry significant liability for subcontractor work and project defects (filing fee: $50)
- 2
Obtain your Missouri general contractor license — requires experience documentation, exam, and financial statements in most states
- 3
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-figure annual cost; both are required for most permits and contracts
- 4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
- 5
Register with Missouri Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
- 6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
- 7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
- 8
Get workers' compensation insurance before hiring any employees or subcontractors — Missouri requires WC for all construction workers
