NC Plumbing Code - Administration

Chapter 1: Scope and Administration

Much of this chapter has moved to another book – North Carolina Administrative Code andPolicies – which should be studied in addition to the Plumbing Code. What is left is general requirements for existing structures, temporary facilities, repair, and remodeling. There is also a section on inspection and jurisdiction.

It often comes into question, “What requires a permit, and what should be inspected?” Those requirements are addressed in this section.

All new construction and additions to existing plumbing systems require a permit and inspections. Some minor repairs and replacements can be completed without a permit, but they are very limited. You can, for example, change out an existing fixture, such as a faucet or toilet, without permit or inspection. You can even replace a water heater if it is the same size and fuel source, but not if the piping needs to be rerouted – so if you are moving the heater to the other side of the laundry room or closet you need a permit.

The basic rule is – you can replace piping and appurtenances exactly as they exist, but if the system must be altered then a permit and inspection is required.

The code also touches on historical structures and new innovation. Since historical structures must remain as they were constructed for historic purposes, the code allows for replacement and repair by historic methods that may now be prohibited by code. It also allows for special engineered designs that may allow new innovations of materials and methods. In all of these special cases a great deal of latitude is given to the local code official to use discretion.

This brings up a point that runs throughout the code – local rulings and the authority of the local inspector. The local inspector is expected to interpret and arbitrate the written code along with possible local ordinances or accepted practices. There may be requirements imposed by the local health department, for example, or minimum standards for a specific type of building. Much is left to the inspectors discretion when performing inspections.

It is always a good idea to check with the local official on anything that doesn't seem clear in the code. It never hurts to ask a question.

If you are working toward your journeyman or technician license there will be less emphasis on administration and more on piping systems on the test. But it is still important to understand the laws and regulations that must be followed. If you are working toward a state contractors or “Masters” license you will need a copy of North Carolina Administrative Code and Policies. In either case there will be questions on administration.
