Massachusetts Contractor Insurance Requirements
Massachusetts has strict workers' compensation requirements, requiring all employers — including sole proprietors in some cases — to carry coverage. The Massachusetts Office of Consumer Affairs and Business Regulation licenses home improvement contractors, requiring GL and WC insurance. Massachusetts General Law Chapter 152 governs WC, and the state's Construction Industries Fair Practice Act affects subcontractor classification. Boston's dense commercial property market drives some of the highest COI standards in New England.
