N.H. Rev. Stat. Ann. § 205-A:15

Any manufactured housing owner who rents a lot in a manufactured housing park, where a condition exists which may endanger or materially impair the health or safety of the manufactured housing owner or the health and safety of the public, may file a petition in the superior court against the owner of the manufactured housing park to enjoin the threat to health and safety. Such petition shall set forth the defective condition and the reason that it poses a threat to the health and safety of the petitioner, other tenants, or public at large, and that said condition was not substantially caused by the tenant or any other person acting under the tenant's control. The petition shall also state that the owner or tenant has been notified of the condition not less than 14 days prior to filing of the petition.
