The Lexington Avenue station has been a vital part of the city's west side for 131 years. It opened in 1894 to house a horse-drawn chemical company. Thirty-four years later, it became known as Station 9 when a 1928 American LaFrance "Triple Combination" fire engine was put into service as Engine 9.

As a community fixture, the station was continuously staffed by firefighters and equipped with various apparatus. However, on February 11, 2021, the city began a long-overdue renovation of the facility. The project took 16 months to complete and cost $4.3 million. Engine Company 9 has since returned to its quarters, where generations of firefighters can safely live with modern amenities while continuing to serve the needs of the city.
