New Hampshire contractor license requirements
Quick answer
New Hampshire contractor license requirements
New Hampshire issues no state general contractor license and runs no contractor exam; most towns do not license general contractors either. Contractors register their business with the Secretary of State and, for home improvement jobs over $500, must use a written contract under the state's Home Improvement Contracts statute. Plumbers, electricians, and a few other trades are licensed separately, statewide.

New Hampshire regulates contracting through no state contractor licensing at all. This page lays out exactly what New Hampshire requires: the licensing agency, who must be licensed, experience, exams, fees, the financial responsibility mechanism, and reciprocity, every figure sourced and dated below.
Who must be licensed in New Hampshire
No state general contractor license; the Secretary of State handles business registration and specific trades are licensed separately is the licensing authority. No state contractor license or exam; most cities and towns also lack a general contractor license.
This is an honest gap, not a coverage failure: New Hampshire genuinely does not run the kind of statewide general contractor competency system that states like California or Georgia do. See the national comparison for how New Hampshire stacks up against every other jurisdiction, and the do I need a contractor license guide for what that means in practice.
Experience and qualification
None required at the state level; any local requirements are set independently by the municipality.
Exam
No state exam for general contracting. New Hampshire does license specialty trades statewide, including plumbers, electricians, asbestos abatement, and lead abatement.
Financial responsibility
New Hampshire uses no bond or net worth requirement as its financial-responsibility mechanism. No state bond for general contracting; a written contract is required for home improvement work over $500 under the Consumer Protection Act.
Reciprocity and the NASCLA exam
New Hampshire is not on NASCLA’s participating-agencies list, confirmed directly against NASCLA’s own page, so a NASCLA Accredited Examination credential from another state does not by itself satisfy New Hampshire’s requirements. See contractor license reciprocity for what does carry over, and the 50-state comparison for which states do accept the NASCLA exam.
