With Proposition D bond funds, La Mesa rebuilt Fire Station 11 on Allison Avenue downtown in 2006. In March 2010, the city reopened an improved Fire Station 13 at 9110 Grossmont Blvd. on the city's eastern edge. A third firehouse, Fire Station 12, is at 8844 Dallas St. in the northern part of town.

La Mesa also contracts with American Medical Response, or AMR, for emergency and non-emergency medical transport services. La Mesa Fire Department works with the Burn Institute of San Diego and its Juvenile Firesetter Program, which educates and counsels children about the dangers of playing with fire.
