When is a permit required?
If you are going to install new, alter, replace, repair, relocate, reinstall, or change the waste and/or vent, water, or gas for a plumbing system, the Saint Paul Department of Safety and Inspections requires that you obtain a plumbing permit.
Why are permits necessary?
- Properly functioning plumbing systems protect the health of the citizens.
- Plumbing systems carry both drinking water and wastewater. If the wastewater mixes with the drinking water, there is a chance people using that system could get sick.
- A plumbing system built according to the plumbing code is a safe system.
