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.

1
Starting without proper licensing — unlicensed plumbing work is illegal in most states and voids homeowner insurance

Undercharging for emergency calls — after-hours plumbing should charge 1.5-2x standard rates

Not carrying adequate general liability — a burst pipe flood claim can easily exceed $50,000
4
Not building service agreements with property management companies — recurring commercial work provides stability
5
Neglecting the HVAC and water heater segment — water heater replacement is one of the most profitable single services

Frequently Asked Questions

Starting a plumbing business costs $15,000 to $150,000. A solo licensed plumber with a used van and basic tools can launch for $15,000-$30,000. A plumbing company with 2-3 plumbers, well-equipped vans, and more comprehensive equipment typically costs $50,000-$100,000. Larger operations with sewer cameras and hydro-jetters can exceed $150,000.

Plumber labor rates range from $75-$200/hour depending on market and complexity. Emergency after-hours calls command 1.5-2x standard rates ($150-$300/hour). Service calls typically have minimum charges of $75-$150. Most plumbing jobs are priced flat-rate by the job (water heater replacement: $600-$1,500; drain cleaning: $100-$350) rather than strictly by the hour.

Most states require a master plumber license to own and operate a plumbing business. Requirements typically include: journeyman experience (4-5 years), passing a master plumber exam, and registering with the state contractors board. Licenses cost $100-$500. Some states allow journeyman plumbers to work independently for limited scope work.

Primary sources: (1) Google searches ('plumber near me', 'emergency plumber') — Google Ads and Google Business Profile with reviews are essential, (2) Angi Leads and HomeAdvisor for new business, (3) Nextdoor for neighborhood recommendations, (4) property management companies for ongoing service, and (5) builder relationships for new construction.

A solo licensed plumber can earn $100,000-$200,000/year running their own business. A company with 3-4 employed plumbers can gross $500,000-$800,000 annually. Net margins of 20-40% after labor, vehicle costs, and overhead generate strong owner income. Emergency plumbing service (nights, weekends) commands premium rates with similar overhead.
