These hangar homes are unique structures with specific fire protection and life safety requirements. The International Building Code (IBC) defines a residential aircraft hangar as, “an accessory building less than 2,000 square feet and 20 feet in building height constructed on a one- or two-family property where aircraft are stored.”*
Section 412.5 of the IBC outlines the requirements for residential aircraft hangars:
- The living space and hangar space are required to be separated by a minimum of 1-hour fire-resistance rated assembly.
- (2) Means of egress are required from the hangar area.
- Hangar building systems (electricity, plumbing, HVAC, etc.) are to be independent from the living space/dwelling building systems.
- Smoke alarms are required to be installed throughout the structure. The hangar area is required to have a minimum of (1) smoke alarm. The hangar and dwelling smoke alarms are to be interconnected.
*This definition is not intended to limit the size of a residential hangar. Hangars that exceed these height and area requirements can no longer be classified as a “residential aircraft hangar”, and must be protected and built in accordance with the requirements of NFPA 409.
