Unattended Death and Biohazard Cleanup in Haddon Heights, NJ

Haddon Heights is a borough in Camden County, New Jersey, incorporated by an act of the New Jersey Legislature on March 2, 1904, from portions of the now-defunct Centre Township and parts of Haddon Township.

The borough was named for Elizabeth Haddon, an early settler of the area, and European settlement of the land dates to 1699, when John Hinchman settled there.

Haddon Heights began as a planned railroad suburb: in 1890, developer Benjamin A. Lippincott built a passenger station for the Atlantic City Railroad and laid out a grid of streets, and large Colonial Revival, Queen Anne, and Foursquare houses soon rose for prosperous families leaving the cities; Lippincott became the borough's first mayor in 1904.

The 2020 United States census counted 7,495 residents in Haddon Heights, an increase of 0.3% from 2010, though the borough's population had peaked at 9,365 back in 1970.

The 2020 census counted 3,009 households in the borough's 1.57 square miles.

Haddon Heights is a dry town where alcohol cannot be sold, although a November 2024 non-binding referendum asking voters to allow liquor sales at restaurants and bars passed by a two-to-one margin.

One of the borough's landmark homes is the Col. Joseph Ellis House, a frame dwelling built by 1720 and later enlarged by Revolutionary War officer Col. Joseph Ellis; New Jersey governor Joseph Bloomfield later purchased the property.

Haddon Heights Junior/Senior High School also serves students sent from the neighboring communities of Barrington, Lawnside, and, starting with the Class of 2019, Merchantville.

The Haddon Heights Public Library traces its roots to a library association dating back to 1902, and its collections hold more than 46,000 volumes.

In 2011, New Jersey Monthly named Haddon Heights the second-best town to live in Southern New Jersey, behind only Moorestown.
