You can do the work yourself if you own and occupy a single family residence and you have taken and passed the Plumbing Homeowner’s exam (70+ score). You may call 704-336-8000 with a touch tone phone and give your permit number (digits only) to our 24-hour automated system. Permits and inspections are required on most work, but there are some exceptions (see below). To apply for a permit, contact us at 704-432-RTAC (7822) or visit the Code Enforcement Department at 700 North Tryon Street in Charlotte. If you would like to speak to an inspections request clerk, please call 704-336-3830 and provide your permit number (example P0345234) and what type of inspection (example sewer, water service, etc.) you need and we will handle the rest.
