New plumbing systems and parts of existing systems that have been altered must be inspected and tested.

The plumbing contractor should notify the proper administrative authority at least eight hours before the work is to be inspected or tested. Schedule inspections of projects in areas that do not have a local inspection department or building official by contacting the plumbing standards representatives for your region.

Contact us to inspect the following projects:

  • State licensed facilities, public buildings and projects of a special nature as determined by us or the municipality in:

    • all non-code enforced areas of the state and

    • code enforced areas of the state where the municipality does not have both a plumbing plan review agreement with us and a licensed plumber to perform the inspections.

  • All other building types in non-code enforced areas of the state.

  • All other building types in code enforced areas of the state where the municipality does not have a licensed plumber or someone meeting the competency requirements to perform the inspections (Minnesota Statute 326B.135).
