Building Permit Application (includes Plumbing and Mechical permit information)    

To find out if you need a building permit, call the Township Office.  For any project, please verify in advance if a permit is needed.  A building permit packet and checklist explaining what is needed to apply for a building permit is available at Castle Rock Town Hall.

Some examples of projects where permits are required:

  • New buildings
  • Additions (bedrooms, family rooms, garage, etc.)
  • Residential Work (decks, pools, fireplaces, roofing, re-siding, new windows, etc.)
  • Remodel (basement finish, kitchen remodel, etc.)
  • HVAC (heating, ductwork, air conditioning, etc.)
  • Plumbing
  • Electrical (permit from State of Minnesota)
  • Septic

A building permit gives you legal permission to start construction of a building project.  Working with a building inspector will ensure the project is built right, will be safe, and will last.  Safe construction practices help protect you, your family, your friends, and your investment.

To receive a permit, an application for a permit must be completed at the Town Hall. At the time of application, a filing fee and a down payment for inspection must be paid, and three (3) sets of site plans and building plans must be submitted.

If the construction project is within County shore land/floodplain jurisdiction, a permit is required from the Shoreland Administrator.

The building inspector will then approve the plan or state which changes will need to be made before approval at their regular meeting.  After the plans are approved by the Board, and all fees are received, the cleark will then release the building permit, and the construction may begin.

Please call the building inspector (952-442-7520) 24 hours in advance to schedule the required inspections.
