Becoming a home inspector in Montana means working under the Department of Labor & Industry. Montana requires registration rather than full licensure, with applicants completing 40 hours of home inspection instruction OR passing a department-approved national examination such as the NHIE. The state mandates $100,000 in liability insurance and $100,000 in E&O coverage, plus workers' compensation coverage or an Independent Contractor Exemption Certificate (ICEC). Billings, Missoula, and Bozeman lead Montana's inspection market, with the Bozeman corridor in particular seeing strong demand from relocation buyers.
