What is meant by the term "Authority Having Jurisdiction" (AHJ)?

The term "Authority Having Jurisdiction" (AHJ) refers to an organization or individual who is empowered to enforce codes, standards, and regulations within a specific area or jurisdiction. This might include the enforcement of building codes, fire codes, safety regulations, and any applicable local ordinances. The AHJ has the authority to approve plans, issue permits, and conduct inspections to ensure compliance with the codes and standards applicable to specific projects, such as the installation of sprinkler systems.
