N.H. Rev. Stat. Ann. § 205-A:6
I. A manufactured housing park owner or operator shall fully disclose in writing all terms and conditions of the tenancy including rental, utility and service charges, prior to entering into a rental agreement with a prospective tenant. No charges so disclosed may be increased by the park owner or operator without an explanation for the increase and specifying the date of implementation of said increase, which date shall be no less than 60 days after written notice to the tenant, and providing notice of the opportunity for voluntary private mediation of the increase under the Manufactured Housing Consumer Action Program. Nothing in this section, however, shall be construed to permit a park owner or operator to vary the terms of a written or oral rental agreement without the express written consent of the tenant.
I-a. (a) Every notice of rent increase issued by a park owner pursuant to paragraph I shall contain the following statement in 10 point bold face print:
IF YOU OBJECT TO THIS RENT INCREASE AS ARBITRARY OR UNREASONABLE YOU MAY BE ABLE TO ENGAGE IN MEDIATION, WITH THE COST OF THE MEDIATOR TO BE FULLY PAID BY THE PARK OWNER, IF: AT LEAST ONE ADULT MEMBER OF NO LESS THAN 51 PERCENT OF THE HOME OWNERS IN THE PARK SIGNS A PETITION REQUESTING MEDIATION, and THE RENT INCREASE EXCEEDS $15 PER MONTH.
