All docks, hoists, buoys, and rafts placed in or over any water open to the public in the state of Iowa must now have a permit. Iowa Administrative Rule 571 - Chapter 16
Installing a new boat dock with electrical? Take note!
All docks must have a sign with their local 911 street address, city and permit number. The information shall be displayed in block letters and numbers at least 1 inch high in a color contrasting with the background, on the water end of the dock, facing away from shore, and shall be plainly visible. The name is not required.
Any fees owed to the department shall be paid in full prior to the installation of any portion of an individual private dock or commercial dock and before a boat is placed in a hoist or slip.
Each dock, hoist, moored vessel or other permitted structure shall be offset a minimum of 5 feet from an adjoining property line. A minimum gap of 10 feet shall be maintained between adjoining docks (including “L” or “T” or catwalk segments), hoists or moored boats. There are exceptions to the offset, length limits, number of hoists and slips, and platform size requirements. Please see the dock rules for details. An Exception Application must be attached to the Class 3 or Class 4 dock permit application.
Class 3 - Non Standard Private Dock
All private docks that are not authorized by Class 1 or Class 2 permits shall require a Class 3 dock permit. Class 3 docks on a natural lake may extend the greater of 100 feet from the water’s edge or far enough so that the outer 80 feet of the dock is in 3 feet of water up to a maximum of 300 feet from the water’s edge. These lengths shall be measured from the water’s edge when the dock is installed. All private docks that have more than two hoists/lifts/slips/racks or a platform that is larger than 200 square feet but no larger than 240 square feet or any raft, platform, mooring buoy or other structures, or an exception to the five foot offset from the property lines must have a Class 3 permit. These permits cost $125 for a five-year permit. Class 3 private dock permits allow a maximum of one hoist or slip for each ten feet of shoreline. There is a fee of $50 per hoist or slip for each hoist or slip in excess of four.
