General Business License
Michigan does not have a statewide general business license. Businesses must register their entity with the Michigan Department of Licensing and Regulatory Affairs (LARA) — Corporations Division and register with the Michigan Department of Treasury for sales tax and withholding tax. Many Michigan cities require a local business license — Detroit, Grand Rapids, Lansing, and most larger municipalities have their own licensing systems. Michigan's LARA also oversees hundreds of professional licensing programs.

Next Steps to Launch Your General Contracting Business
- 1
Form your LLC or corporation in Michigan — general contractors carry significant liability for subcontractor work and project defects (filing fee: $50)
- 2
Obtain your Michigan 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 Michigan 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 — Michigan requires WC for all construction workers
