A plumbing permit is not required in the following circumstances:
- When a property owner does “ordinary minor repairs” to plumbing systems on his or her own property, which means repair, replacement, or maintenance of existing accessible fixtures, parts, and appliances and their related water and drain attachments. Do not alter an existing plumbing system without a permit.
- When a property owner or licensed plumber performs emergency repairs to, or replacement of, freeze-damaged or leaking concealed piping, provided new piping doesn’t exceed 3 feet in length.
