How to Start a Commercial Construction Company in the USA
Commercial construction in the USA pays significantly better margins than residential – but the entry requirements are substantially higher. Here’s what it takes.
Key Differences: Commercial vs Residential
| Factor | Residential | Commercial |
|---|---|---|
| Contract size | $5K-$500K | $100K-$50M+ |
| Insurance minimums | $1M GL | $2M-$5M GL |
| Bonding | Often optional | Almost always required |
| Payment terms | Deposit + completion | AIA payment applications, 30-60 day terms |
| Prequalification | Rarely required | Routinely required |
| Licensing | Varies by state | Stricter requirements |
Prequalification Requirements
Before most commercial clients award contracts, they require prequalification demonstrating: – Financial capacity – minimum annual revenue, working capital ratio – Experience – completed projects of similar size and scope – Safety record – OSHA 300 log, EMR (Experience Modification Rate) below 1.0 – Insurance – certificates naming the client as additional insured – Bonding – Performance and Payment bonds, typically 100% of contract value
Major clients use platforms like ISNetworld, Avetta, or Browz for vendor prequalification.
OSHA Requirements for Commercial Construction
Commercial construction sites in the US typically require: – OSHA 10 for all workers – OSHA 30 for supervisors and foremen – Site-specific safety plans – Regular toolbox talks documented in writing
OSHA 10 and 30 courses are available online ($30-$200) through OSHA-authorized providers.

What insurance do I need for commercial construction in the USA? At minimum: $2M/$4M General Liability, Workers Compensation (legally required with any employees), Commercial Auto, and Builder’s Risk per project. Many commercial clients require $5M GL and an umbrella policy. See your state’s AGC chapter for market norms.
How do I get my first commercial construction contract? Start with subcontracting on commercial projects to build your project history and safety record. Direct bidding on commercial GC work requires a proven portfolio – typically 3-5 completed projects of comparable scope.
