In Holmdel Builder's Association V. Holmdel Township, 121 N.J. 550 (1990), the New Jersey Supreme Court determined that mandatory development fees are authorized by the Fair Housing Act of 1985 (the Act), N.J.S.A. 52:27d-301 et seq., and the State Constitution, subject to the Council on Affordable Housing's (COAH's) adoption of rules.

COAH was authorized by c.46 Section 8 (N.J.S.A. 52:27D-329.2) and the Statewide Non-Residential Development Fee Act (N.J.S.A. 40:55D-8.1 through 8.7), to adopt and promulgate regulations necessary for the establishment, implementation, review, monitoring and enforcement of municipal affordable housing trust funds and corresponding spending plans. Municipalities that are under the jurisdiction of the Council or court of competent jurisdiction and have a COAH- or court-approved spending plan may retain fees collected from nonresidential development.

In Re: Adoption of N.J.A.C. 5:96 and 5:97[1] by the New Jersey Council on Affordable Housing. 221 N.J. 1 (2015), also known as the Mount Laurel IV decision, the Supreme Court remanded COAH's duties to the Superior Court. As a result, affordable housing development fee collections and expenditures from the municipal affordable housing trust funds to implement municipal Third Round Fair Share Plans through July 1, 2025, are under the Court's jurisdiction and are subject to approval by the Court.

This section establishes standards for the collection, maintenance, and expenditure of development fees pursuant to COAH's regulations and in accordance P.L. 2008, c.46, Sections 8 and 32-38.[2] Fees collected pursuant to this section shall be used for the sole purpose of providing low- and moderate-income housing. This section shall be interpreted within the framework of COAH's rules on development fees, codified at N.J.A.C. 5:93-8.[3]
