The Michigan Residential Builders and Maintenance & Alteration Contractors Board was created under Article 24 of Public Act 299 of 1980, as amended, to license and regulate persons engaged in the construction of a residential structure or combination residential and commercial structure, or persons who undertake the repair, alteration, addition, subtraction or improvement of a residential structure or combination residential and commercial structure for compensation other than wages for personal labor.

A state license must be displayed in the place of business and all contractors and their salespersons must carry a pocket card which you should ask to see. If they cannot show you a license, check the department's License Information database or call the Verification Unit at (517) 241-9288.
