According to the code, who has the final authority on approving items related to mechanical systems?

The mechanical official has the final authority on approving items related to mechanical systems according to the code. This role is crucial because the mechanical official is responsible for ensuring that all mechanical installations comply with relevant codes and standards. This includes oversight of safety, efficiency, and proper installation practices. The mechanical official typically reviews plans, conducts inspections, and issues permits, ensuring that all mechanical work meets both local and state regulations.

This authority is essential in maintaining the integrity of building systems and ensuring they function correctly and safely. Other roles, such as architects, contractors, and designers, may play important parts in the design and execution of mechanical systems, but the mechanical official has the ultimate responsibility for enforcement of the code and adherence to safety standards. Consequently, their approval is necessary before any mechanical work can proceed.
