Construction Defect Laws in New Hampshire.

New Hampshire construction defect claims are governed by the general 3-year statute of limitations for property damage and an 8-year statute of repose from substantial completion (RSA 508:4-b). New Hampshire requires pre-suit notice and opportunity to inspect and repair under the Construction Defect Dispute Resolution Act (RSA Chapter 359-G). Mechanics' liens provide security for contractor payment. New Hampshire does not impose a statewide general contractor license but various trades require licensing.
