Sprawling Former Corporate HQ Makes Way for up to 8 Manufacturing Mixed-Use Buildings

By Hank Russell

A final portion of the former Computer Associates (CA) building came down on January 19 in a planned demolition.

The building, which once sat on the 70-acre property in Islandia, has now made way for light industrial and limited manufacturing use on the former CA campus. 

In 2014, CA relocated its headquarters to New York City and reduced its staffing at its Long Island office. Over time, parts of the building were rented out to smaller companies, but it was never rented out to full capacity. Those businesses have since moved out, leaving the building vacant.

In 2021, the current owner bought the note on the property at foreclosure. Due to a lack of interest in commercial office space, and with input and support from Islandia residents, the village rezoned the property in early 2023 for light industrial and limited manufacturing use and approved the construction of up to eight buildings on the property for manufacturing purposes.
