Licenses & Permits in Michigan

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.

Most Michigan municipalities allow home occupations with restrictions on customer traffic, exterior commercial signage, and non-resident employees. Michigan's cottage food law explicitly supports home-based food production and direct consumer sales.

Common Mistakes to Avoid

1
Underestimating material costs and change order frequency
2
No lien waiver process protecting cash flow
3
Subcontractors without proof of insurance
4
Poor project scheduling causing costly delays
5
No written contracts with payment schedules

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 ($10,000–$50,000) and general liability insurance ($2,500–$8,000/year) — 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

Frequently Asked Questions

Starting a general contracting business typically requires $20,000–$55,000, covering contractor licensing ($500–$2,000), surety bond, liability insurance ($1,500–$4,000/year), workers comp, a reliable work vehicle, tools, and working capital. Materials for active projects can require significant additional capital.

Most states require general contractors to be licensed. Requirements vary — some require passing a trade exam, others require proof of experience and financial responsibility. California, Florida, and Texas have strict requirements. Check your state contractor licensing board for specific requirements.

GCs earn 10–25% markup on subcontractor labor and materials. On a $200,000 remodel, a 15% GC margin generates $30,000 gross. After overhead, net margins average 8–15%. Larger commercial projects have lower margins but higher volume; custom residential work often commands 15–20%.

If subcontractors are true independent contractors with their own workers comp, the GC may be exempt. But if a subcontractor lacks coverage, the GC's policy may pay their claims. Always verify subcontractor insurance certificates — liability flows to the GC in most states.
