Docks, those narrow structures used for getting to deeper water, are commonly used on Minnesota lakes and rivers. For many docks, no permit is needed to install, construct, or reconstruct on shoreline property. For certain docks, a general permit may be used. There are many options, and we recommend that landowners use the smallest and narrowest dock that will reasonably meet their water access needs.
Do I need a permit for my dock?
No permit is needed to install, construct, or reconstruct your dock on shoreline property you own if you comply with the following:
- No area of the dock is wider than 8 feet.
- The dock is not combined with other similar structures to create a larger structure.
- The dock is no longer than needed to achieve its intended use, including reaching navigable water depth.
- The dock is not a hazard to navigation, health, or safety.
- The dock will allow the free flow of water beneath it.
- The dock is not used as a marina.
- The dock is consistent with guidelines of the local government.
- Docks placed on rock-filled cribs are located only on waters where the bed is predominantly bedrock.
