In Michigan, most “handyman” work is regulated through the state’s Residential Builder and Maintenance & Alteration Contractor (M&A) licensing system when you’re working on residential structures. Michigan does not offer a simple statewide “handyman license,” and there is no broad, dollar-based handyman exemption you can rely on for residential work—if you’re doing repairs/alterations on a residential structure for compensation, you generally need the appropriate state license/registration, and you still must avoid regulated trades (electrical/plumbing/HVAC) unless separately licensed and permitted.
