Summary
In the City of Duluth, a resident's own boat dock is a permitted accessory use with no limit on how many boats the owner keeps there, but renting dock space to others is capped and depends on whether the property fronts an improved street, under the Unified Development Chapter's accessory-use standards.
C. Accessory boat dock, residential. This use shall comply with the following standards: 1. Dockage of boats owned and primarily used by a resident of the property is a permitted accessory use to the primary residential use and shall not be limited in number; 2. If there is a residential structure on the property and the property has frontage on an improved street, the owner of the residential structure may rent out boat dockage to a maximum of two boats owned by others. If the property does not have frontage on an improved street, the owner of the residential structure may not rent dockage space to others.
Full Breakdown
C rather than something needing a separate harbor permit for ordinary dock use. Dockage of boats owned and primarily used by the resident of the property is allowed as of right and is not capped in number, so a homeowner can keep as many personal boats at their own dock as fits. Renting dock space to others is treated differently and turns on street frontage: if the lot has a residential structure and frontage on an improved street, the owner may rent dockage to a maximum of two boats owned by others; without frontage on an improved street, no rental dockage is allowed at all.
A property that is not residentially developed can still use a dock as a principal use, but only for one boat per lot (or group of contiguous commonly-owned lots), owned and primarily used by the property owner. Any new rental dock space created after April 14, 1974 must come with one additional off-street parking space built to Section 50-24 standards, on top of whatever parking the property's other uses already require. The Land Use Supervisor (the building official) can demand boat registration or other documentary proof of compliance, and the standard bars ancillary commercial activity outright: no non-residential buildings, no winter boat storage for non-residents' boats, no repair, fuel, food, rental, or sales operations tied to the dock.
Violations & Fines
Because Section 50-20.5.C is a use-specific zoning standard, a dock that exceeds the two-boat rental cap without street frontage, skips the required off-street parking space for a post-1974 rental slip, or runs a prohibited commercial use like boat repair or fuel sales is a Unified Development Chapter violation, enforced through the chapter's general nonconformity and enforcement provisions rather than a standalone dock-permit fine.
