Fire Sprinkler Systems in Manufactured Housing Units

Release Date:
February 4, 2021

One step in the housing process includes the installation of a safety feature—every manufactured housing unit (MHU) provided by FEMA is equipped with a residential fire sprinkler system (fire sprinklers are not provided in recreational vehicles).

Research has shown that fire sprinkler systems combined with smoke alarms can reduce the risk of dying in a home fire by more than 82%. Fire sprinkler systems save lives, prevent injuries, and protect property. 

  • All FEMA MHUs are equipped with smoke alarms in the living area and in each bedroom.
  • Sprinklers are in located in each room. 
  • Fire sprinkler systems are designed to control the spread of a fire long enough for occupants to evacuate.
  • The entire system has been designed and tested to operate at temperatures as low as 35 degrees below zero.
  • The fire sprinkler system is not connected to the domestic water system that supplies the sinks and baths in the home. It has a separate water tank and pump located in a small structure outside the unit called the Tank and Pump System (TPS) (pictured).  
  • FEMA contractors perform monthly maintenance.
  • Fire sprinklers and smoke alarms are not a substitute for a household’s emergency plan. All households should make a fire-escape plan and make sure everyone knows what it is.
