South Bound Brook was incorporated as an independent borough by an act of the New Jersey Legislature on April 11, 1907, based on the results of a referendum held on May 1, 1907.

[24] The brook, which was mentioned as a boundary in a Native American deed, provides the source of the borough's name.

The Abraham Staats House (c. 1740), located on the south side of Main Street, served as the headquarters of Baron Von Steuben during the American Revolutionary War.

[27] The house remained a private home until it was acquired by the Borough of South Bound Brook in 1999.

During the Revolutionary War, the bridge was used repeatedly by both sides including during the Battle of Bound Brook in 1777.

At this spot on January 4, 1777, General Washington decided to move his troops to Morristown for the winter, thus ending the victorious Trenton-Princeton campaign, rather than attack New Brunswick.

[30] At dawn on April 13, 1777, Hessian Captain Ewald's assault over the Queens Bridge spanning the Raritan River between South Bound Brook and Bound Brook was pinned down by "murderous fire" from the American soldiers stationed at half moon battery.

Advancing North along present day Easton Avenue, Hessian Colonel Donop pushed aside American outposts and arrived 15 minutes after Ewald's attack had faltered.

Advancing over the Queens Bridge, Donop's troops engaged the Americans causing them to retreat from the battery.

Originally called the Dutch Reformed Church of Bound Brook, it has gone through very few changes over the years.

A pipe organ received from Andrew Carnegie has been removed, and the stained glass windows, which had been added well after the original construction.

Originally part of Franklin Township and named Bloomington, South Bound Brook was incorporated as a borough by the New Jersey Legislature in 1907.

New townhomes have been built on the GAF Manufacturing site, along the Delaware and Raritan Canal, which provide the downtown area a new modern look and many new residents.

[40][41] The main attraction in South Bound Brook is the Delaware and Raritan Canal, which forms the northern and eastern boundaries of the town.

Also of note is the Raritan River which lies on the far side of the canal and provides further recreational opportunities such as boating and fishing.

[7] The borough form of government used by South Bound Brook is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie.

[46] Members of the Borough Council are Council President Richard Eickhorst (D, 2023), Kathleen Connor (D, 2022), Anne Dedousis (D, 2023; appointed to serve an unexpired term), Kathryn M. "Katie" Kelly (R, 2022), Elizabeth Konkle (D, 2024) and Jitendra "Jimmy" Shah (D, 2024).

[3][47][48][49][50][51] In February 2022, the borough council appointed Anne Dedousis to fill the seat expiring in December 2023 that had been held by Elizabeth Chu until she resigned from office the previous month.

[52] In August 2015, the borough council selected Kathryn M. Kelly from three candidates nominated by the Republican municipal committee to fill the seat expiring in December 2016 that had been held by James Holmes until he resigned from office the previous month as he was moving out of the borough.

[59] The records show that Mayor Warrelmann, along with his son Stephen, Nancy Santora and an unidentified juvenile, were suspects in an investigation of a November 21, 2009, burglary of a shed in South Bound Brook.

[61] For the 119th United States Congress, New Jersey's 12th congressional district is represented by Bonnie Watson Coleman (D, Ewing Township).

[64] For the 2024-2025 session, the 17th legislative district of the New Jersey Legislature is represented in the State Senate by Bob Smith (D, Piscataway) and in the General Assembly by Joseph Danielsen (D, Franklin Township) and Kevin Egan (D, New Brunswick).

[82] Among the borough's 2010 Census population, 51.6% (vs. 60.4% in Somerset County) were registered to vote, including 65.6% of those ages 18 and over (vs. 80.4% countywide).

[99] The police department does not have its own dispatchers; South Bound Brook currently uses Somerset County Communications for all 9-1-1 and non-emergency calls.

Somerset Medical Center EMS Units take calls in South Bound Brook during the workday and weekends due to lack of volunteer personnel available.

[99] The Abraham Staats House was built c. 1740 and served as the headquarters for General Baron von Steuben in 1779 during the second Middlebrook encampment of the American Revolutionary War.

The house was added to the National Register of Historic Places in 2002, and noted as representing "one of the finest remaining buildings from the second phase of Dutch immigration and settlement in the Raritan Valley".

In September 1999, the remnants of Hurricane Floyd caused a record flood crest on the Raritan River.

While escaping the worst flooding, due to its elevated perch above the Raritan River, South Bound Brook did experience flood waters in the two- to three-foot range near the canal, including in portions of the downtown area along Main Street.

[106] Interstate 287, which provides access and connections to large parts of New Jersey and New York City, passes just to the southwest of South Bound Brook in Franklin Township, with two interchanges providing quick access to South Bound Brook.
