Sayreville was originally settled by Europeans in the colonial era and was part the South Amboy Township formed in 1684. It seceded and incorporated as a township on April 6, 1876. The newly formed Township of Sayreville was created out of approximately 14 square miles of south of today's South Amboy consolidating the settlements at Morgan, Melrose, Ernston, and Sayre's Village under one municipal government. The area around the village was then known as Wood's Landing was renamed Sayreville after Sayre and Fisher Brick Company. Fewer than 2,000 people resided in the new township. Several areas take their name from stations along the Raritan River Railroad.^{[citation needed]}

Sayreville developed into an industrial town in the late 19th century when most of the land was owned numerous clay, sand, and brick companies such the Such Clay Company, the Furman Brick Company, the Crossman Sand & Clay Company, Whitehead Brothers, and the Sayre & Fisher Brick Company, once the largest brickworks in the world. With the coming of other industries at the turn of the century such as DuPont, Hercules, and National Lead, Sayreville promoted itself as the “Home of Nationally Known Industries.” On April 2, 1919, the township was reincorporated as the Borough of Sayreville and ratified by a referendum held on April 29, 1919.^[9]

According to Joseph T. Karcher, an attorney, who wrote the post-war promotional The case for Sayreville, Middlesex County, New Jersey in 1947, the borough had seven residential districts, which were separated by the large industrial complexes throughout the borough.^[10] After World War II, with the sale of former clay land holdings to housing developers. President Park, a suburban subdivision, was built just after the war.^[11] Sayreville's population grew from 8,000 in 1945 to over 32,000 by 1970.

Much of Sayreville's housing was built in the 1940s, 1950s, and 1960s.^[12] In the 1950s many clay companies sold their land holdings and gave way new housing “developments”.^[13] The largest, Laurel Park, became home to over 500 families. Other projects included Pershing Park, Deerfield Estates, Hope Homes, Parkway Homes, and Haven Village. In the 1960s more housing developments such as Woodside, Sayre Woods, and Oak Tree East and West were built.^[14] In 1970s and 80s Sayreville transitioned from an industrial community to a suburb as its once vibrant industrial landscape gave way to housing developments, and as more residents commute to jobs outside of town it became more of bedroom community. By the 2000s, Sayreville's population surpassed 40,000 as brownfield land saw more housing construction.
