Rossmoor is an unincorporated community and census-designated place (CDP) in Monroe Township, Middlesex County, New Jersey, United States.

The community offers a wide selection of living space, from smaller units of 500 sq ft (46 m2), to larger units with 2,300 sq ft (210 m2) of living space, with its architecture primarily being American Colonial in style.

Express buses stop at Rossmoor for the 55-minute ride to the Port Authority Bus Terminal on 42nd Street in Midtown Manhattan.

[citation needed] The concept of a "Senior Community" was an unknown entity in the building trade of the early 1960s.

Through his contacts and research in 1962–63, Ross Cortese identified an area in central New Jersey that seemed to have all the right factors.

He purchase available farm land directly adjacent to the New Jersey Turnpike (whose initial 118 miles had just been built between 1950 and 1952.)

He made sure to offer amenities that would attract buyers, and then he marketed the concept to the surrounding public.

In 1963, Arthur Phillips, Esq., then a young lawyer with offices in the Heritage Building near what is now Rossmoor's North Gate, was hired by Cortese to act as attorney for the purchase of the necessary acreage.

The purchase was a huge tract of land, covering the area that now includes today's Adult Communities of Clearbrook, Concordia, Encore, the Ponds, Whittingham and all the Forsgate land including the Forsgate Country Club.

The work on Village #1 began in earnest soon afterwards, and the Farmland appearance of Monroe changed abruptly.

Rossmoor is overseen by a master association Board of Governors made up of each Mutual's presidents.

Together they assure the care and operation of the communities infrastructure and amenities and provide needed administrative and maintenance services to each Mutual and thus every owner.

His idea expanded even further into Monroe Township providing more and more affordable adult active housing options.
