For plumbing permits, its easier to explain when they are not required. In general, if you need to make changes to your wiring or piping to accomplish the task, then a permit is required.
The knowledge and experience needed to meet the state code for this type of work often requires hiring a licensed contractor. Licensing, not registration, is required for all plumbing contractors. They carry picture identification with their license number. They too must get permits and will have a receipt copy from the Inspection Division.
Plumbing permits are NOT required when
- Replacing a toilet fixture in the same spot. If you want the fixture moved, even a short distance, a permit is required.
- Clearing a blockage in your drain.
