Becoming a home inspector in New Hampshire means working under the Office of Professional Licensure and Certification (OPLC), specifically the Board of Home Inspectors. The state requires 80 hours of board-approved home inspector training, passing the National Home Inspector Examination, a criminal background check through the NH Division of State Police, and proof of liability insurance coverage. New Hampshire's housing stock skews older than the national average, with substantial pre-1960 inventory across Manchester, Concord, and Portsmouth that calls for inspectors trained on knob-and-tube wiring, granite block foundations, and aging cast-iron plumbing.
