N.J. Stat. § 52:27D-324
The agency shall establish procedures for entering into, and shall enter into, contractual agreements with willing municipalities or developers of inclusionary developments whereby the agency will administer resale controls and rent controls in municipalities where no appropriate administrative agency exists. The contractual agreements shall be for the duration of the controls and shall involve eligibility determinations, determination of initial occupants, the marketing of units, maintenance of eligibility lists for subsequent purchasers or renters, and determination of maximum resale prices or rents. The agency may charge the municipality or inclusionary developer a reasonable per unit fee for entering into such an agreement, or may charge a reasonable fee to a low or moderate income household at the time the home is sold subject to the resale control or both. Agency fees shall be established according to methods or schedules approved by the State Treasurer.
Neither the agency nor any other entity entering into an agreement to provide services to a municipality under this section shall require, as a condition of that agreement, that these services be provided for all eligible housing units in the municipality. A municipality, at its discretion, may enter into an agreement for the provision of services for any reasonable portion of its eligible housing units.
