Which entity is referred to as the Authority Having Jurisdiction (AHJ)?

The Authority Having Jurisdiction (AHJ) refers to an organization or agency that has the authority to enforce regulations and approve compliance with codes and standards relevant to construction, safety, and building performance. This entity is responsible for ensuring that all practices, including inspections and approvals, adhere to established legal and safety standards within a particular jurisdiction.

In the context of building performance and energy efficiency sectors, the AHJ plays a pivotal role in approving modifications, installations, and compliance with energy codes, HVAC standards, and installation practices. Their final approval authority is essential for ensuring that projects meet safety and efficiency requirements before they can proceed.

Other options describe entities or individuals that do not possess the same level of regulatory power or final decision-making capability related to code compliance, which distinguishes them from the AHJ.
