Michigan requires contractors performing any work on residential properties to be licensed with the Michigan Department of Licensing and Regulatory Affairs.

Knerr, Karl J currently holds license 6207253, 6107882, 6105889 (Electrical, Electrical Contractor), which was Active when we last checked.

Contractors in Michigan must complete a 60 hour approved prelicensure education class prior to taking a buisness and law exam. Contractors are required to take continuing education upon renewal of an active license.

Michigan requires licensed contractors to carry an active workers' compensation policy. Although general liability insurance is not required under Michigan state law, it is always advisable to hire contractors who carry it. Request copies of the certificates for both forms of insurance for your records.

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.
