STATE LICENSE
NoneSee what applies
No New Hampshire statute licenses or registers concrete contractors. Foundations, footings, and structural slabs are governed by the state building code (RSA 155-A:2, I), which adopts the 2024 International Residential and Building codes (RSA 155-A:1, IV), and the contractor is responsible for meeting the code's minimum requirements (RSA 155-A:2, VII). A permit is required before code-covered work begins (RSA 155-A:4).
Residential contracts over $5,000 must include the RSA 359-G:7 defect-resolution notice, and employers must secure workers' compensation (RSA 281-A:5). Sewer, drain, and water lines inside the building or within 5 feet of it are plumbing that requires a licensed plumber (RSA 153:27, XIV).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
New Hampshire licenses no general construction trades at the state level, so the working gate for this trade is the local building permit. All construction must comply with the state building code (RSA 155-A:2, I) — currently the 2024 International Building, Residential, Existing Building, Plumbing, Mechanical, and Swimming Pool and Spa codes, the 2018 IECC, and the 2023 NEC (RSA 155-A:1, IV). Towns that adopt an enforcement mechanism under RSA 155-A:3 issue permits and inspect; they may adopt administrative amendments but no technical amendments. Where no local enforcement exists, the contractor must notify the state fire marshal of the type of construction before starting, except for one- and two-family dwellings (RSA 155-A:2, VI), and the contractor — not the town — is responsible for meeting the code (RSA 155-A:2, VII).
The local offices section below names the exact permit desk for every New Hampshire county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
New Hampshire has neither a license nor a registration for this trade — your state-level obligations are code compliance, contract notices, and employer law.
Footing and foundation work is code-governed construction; inspections follow the town's RSA 155-A:3 process.
Piping within the building or up to the first fitting beyond the foundation wall (or 5 feet from the building) is plumbing (RSA 153:27, XIV).

Each item names the issuing authority, cycle, and citation.
Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Doing electrical installations without an OPLC license is a crime; plumbing or gas fitting without a license is unlawful practice.
A building official may sue to enjoin, abate, or remove construction that violates the building code or permit conditions.
Violating a local land-use ordinance or a permit condition issued under the planning-and-zoning title.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.

Pending verification: Whether any New Hampshire city or town requires its own contractor registration or business license (no statewide preemption clause was found for general construction trades; check the local building department) · How each town applies RSA 676:17 fines to building-permit violations — the section reaches ordinances and permits issued under the planning-and-zoning title (Title LXIV); some building-code enforcement may proceed instead under RSA 155-A:8 injunctive relief · Whether NH DOT or other state agencies prequalify concrete contractors for state-funded projects (not reviewed)
