Plumbing Subcode
Why are Plumbing Permits Needed

- To make sure contractors are doing code compliant installation and to test for proper installations.
What Type of Plumbing Work Needs Permits & How Does It Relate to Safety, Health & Welfare
- A permit is not required for the replacement of lavatories, vanities or kitchen sinks if the water pipes aren't changed from valve back and the waste line is not changed from the trap arm back.
- Water closets may be changed or removed for floor installation as long as no piping is changed.
- Some of the plumbing work that needs permits includes hot water heaters, boilers and furnaces, air conditioners and heat pumps, additions, small bathrooms, new kitchens, laundry tubs and tub and shower diverters.
