- 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.
