Instructions and Additional Information for the Submittal of Plumbing Plans
The purpose of a plan review is to ensure that the design complies with the Minnesota Plumbing Code (Minnesota Rules, Chapter 4715) and that no plumbing system is installed that may endanger the public health. The Minnesota Plumbing Code requires plans and specifications to be submitted to the Minnesota Department of Labor and Industry and approved prior to construction of any new plumbing system or prior to any change to an existing plumbing system serving a public building. Plans and specifications will not be approved without adequate information to verify compliance with the provisions of the Minnesota Plumbing Code.
Plumbing plan submittals must include the following:
Completed Plumbing Plan Review Application
Utility Site Plan: Show the building, service lines, pipe sizes, slopes, materials, and well and septic system locations on the property. If no new service connections will be installed, include a statement.
Floor Plan: Show all fixture locations, all horizontal drainage pipe locations and all pipe sizes for new plumbing.
Roof Plan: Show the location of roof drains and the roof area served by each roof drain. If no internally piped roof drain will be installed, include a statement.
Water Riser Diagrams: Isometric drawings of the water supply system showing all pipe sizes and all fixtures.
Soil, Waste and Vent Riser Diagrams: Isometric drawings of the waste and vent system showing pipe sizes and fixtures.
Plumbing Specifications: Include a list of the manufacturer and model numbers of the plumbing fixtures, a list of pipe materials including the quality standard (ANSI, ASTM, etc.), testing and disinfection procedures.
Signature: The plans must be designed by either an engineer that is registered in the state of Minnesota, or by the licensed master plumber that will be installing the plumbing. Each sheet must be signed by the designer.
Required Plan Review Fee: Please calculate the required plan review fee carefully. Overpayment or underpayment will delay your plan review. An interactive fee worksheet can be found at: www.dli.mn.gov/CCLD/PlanPlumbingCalc.asp
