When the Clay Township Fire Department was started in 1948, they housed the vehicles at the high school.
In 1949 the school corporation informed Clay Township that they would no longer be able to house apparatus in the school. A station was built that year at 18776 Cleveland Road.
The station was used until 2001 when a new station was built.
In 2013 the firehouse was renamed to Station 21.
Located at 18776 Cleveland Road, Clay Station 21 covers approximately 12 square miles, including 4 miles of the I-80/90 of the Indiana Toll Road. The response area for this district is from the St. Joesph River to the West; Gumwood Road to the East; Darden Road to the North; and the University of Notre Dame to the South.
