Which of the following would NOT require plumbing permits?

The installation of a non-plumbing related appliance does not require plumbing permits because it falls outside the scope of plumbing work regulated by local codes. Plumbing permits are generally required for any work that involves the installation, alteration, or repair of any part of a drainage, water distribution, or sanitary system, including sinks or any fixtures directly related to plumbing systems.

In contrast, construction of a new building would require permits due to the extensive plumbing work typically involved, such as installing sanitation systems and water supply lines. Similarly, installation or alteration of a sanitary drainage system is directly related to plumbing and necessitates a permit to ensure compliance with health and safety standards. The same reasoning applies to the installation of a sink, which is a plumbing fixture that must meet specific code requirements.
