Projects that do not need a permit

Minneapolis Construction Code Services waives the permit, inspection and testing requirements for certain plumbing work in one- and two-family dwellings.

You do not need a plumbing permit to:

  • Reconnect an existing water supply line to a replacement appliance that:
    • Is a similar type
    • Does not involve the replacement or alteration of the existing water supply line
  • Replace the internal working components of existing:
    • Closets
    • Faucets
    • Valves
  • Replace sink faucets when the work does not include alterations to the existing plumbing piping system
  • Replace or reset water closets (a room containing a flush toilet) when the work does not include alterations to the existing plumbing piping systems
  • Replace a clean-out plug
  • Do a minor repair of:
    • Broken drain, waste and vent pipes
    • Leaking fixtures
    • Leaking water pipes
  • Reconnect or replace a dishwasher or ice maker
  • Replace or install a new garbage disposal

Note that we waive permit requirements for the above as long as the plumbing work does not pose an unsanitary or hazardous condition.

For more information about exempt plumbing work , see Minnesota Plumbing Code MN Rules Chapter 1300.0215.

Emergency repairs

You can do an emergency repair without first getting the necessary permit. After you complete the work, you must get the permit within a reasonable timeframe.
