What is an AHJ?
The Authority Having Jurisdiction (AHJ) is a generic term for the code official, or other trained and certified officials, bearing responsibility for ensuring that fire barriers are constructed or installed in a manner prescribed by the manufacturer’s instructions, listings, Fire Code, Life Safety Codes, the facility’s Interim Life Safety Measures (ILSM), and other standards. These officials may include the Inspector of Record (IOR), the Fire Department or Fire Marshal official, or an accredited facility manager.
