Fire barriers play a critical role in protecting patients and staff—and meeting code requirements is essential. But even the most robust wall system won’t fly unless the Authorities Having Jurisdiction (AHJs) sign off on it. For Facilities Managers and Project Managers, understanding who the AHJs are—and how they operate—can mean the difference between inspection approval or costly project delays.
What is an AHJ?
An Authority Having Jurisdiction (AHJ) is an organization, office, or individual responsible for enforcing codes or approving equipment, materials, installations, and procedures.
Depending on the facility and location, AHJs may include:
- Fire Marshals or Fire Chiefs
- Building Officials and Inspectors
- Inspectors of Record (IORs)
- Facility Safety Officers or Accredited Facility Managers
- Insurance Representatives or Rating Bureaus with statutory oversight
Why AHJs Matter in Construction
For Facilities Managers and Project Managers, AHJs are gatekeepers of project compliance:
- Material Approval — Only certified and listed products are acceptable.
- Installation Review — Fire barriers must follow manufacturer specs and code.
- Timeline Management — Failed inspections can cause costly delays.
- Safety Assurance — Properly installed barriers are essential in emergencies.
Engage your AHJs early—before drawings are finalized—to streamline approvals later.
