What does the term "occupancy" refer to in plumbing terms?

In plumbing terms, the term "occupancy" specifically refers to the purpose for which a building is used. This designation is crucial because the type of occupancy directly influences the plumbing requirements, such as the number of plumbing fixtures needed, the size of the pipes, and the capacity of the water supply system. Different occupancies, such as residential, commercial, or industrial, have distinct plumbing needs that must be considered to ensure safety and functionality.

Understanding occupancy helps plumbing professionals adhere to building codes and standards, including those outlined in the International Plumbing Code. By recognizing the intended use of a building, one can assess factors such as the anticipated water usage, waste discharge, and fixture requirements, ensuring compliance with applicable regulations and proper design principles.
