The Township of Mahwah Historic Preservation Commission is governed by a Historic Preservation Ordinance. The Mahwah Historic Sites Committee (HSC) introduced the first Ordinance in 1978, and in 1981 several homes were designated as local historic sites. In 1990, the HSC was renamed the Mahwah Historic Preservation Commission (MHPC), and the Ordinance was amended to conform to the Municipal Land Use Law. Nine years later, the Ordinance was amended again, resulting in several changes to the list of designated sites. In October 2001, the New Jersey State Historic Preservation Office recognized the MHPC as a Certified Local Government.
