The Pine Street Historic District is significant as an intact working class neighborhood, with architecture ranging from vernacular style frame residences built in the 1880s to multi-story masonry buildings constructed during the first decade of the twentieth century to the late 1930s with Renaissance Revival, Italianate, and Classical Revival influences. Built primarily by and for Italian Americans, the district is an excellent example of a cohesive late nineteenth-early twentieth century Italian-American immigrant community that displays the use of masonry construction and exhibits many fine examples of masonry craftsmanship.

The Pine Street Historic District is bounded on the south by Glenridge Avenue, on the north by the New Jersey Transit Boonton Line, on the west by the rear lot lines on properties on the west side of Pine Street, and extends along Glenridge Avenue to include the east side of Baldwin Street.

The Pine Street Historic District consists of a total of 101 properties, including a number of important surviving historic structures. Some of these include the Italian Gothic and Romanesque style Our Lady of Mount Carmel Church at 94 Pine Street, the Renaissance Revival style three-story residential and commercial building at 43 Glenridge Avenue, and the Neo-Classical style former Baldwin Street School at 15 Glenridge Avenue.
