The Joint Field Office (JFO) is the unified command center of the disaster. FEMA, State or Tribal Administration staff, and Other Federal Agencies (OFAs) are primarily located in the JFO. It is also the location of the Federal Coordinating Officer (FCO). Unlike the DRC, it is not a physical location for directly servicing disaster survivors.  The JFO is a management office and provides services remotely.

The JFO’s physical location varies depending on the disaster. It is often in the State capital or located near or adjacent to disaster-affected areas. The JFOs are dependent on the size and scope of the disaster, and on available amenities such as electricity, water, and lodging.
