Property Description
This prime waterfront property is literally the last stop before the harbor, in downtown Belfast. Property abuts the City of Belfast Public Landing. This property offers 98+/-' waterfront directly in front of the building, next to the City slips and Fournier Tugs. Slip your vessel in front and walk up to what is now a restaurant. Does this remind you of San Diego and Key West Yacht Clubs? City utilities, and 14 parking spaces. The anchor tenant is currently Nautilus Restaurant; the floorplan has worked as a restaurant for many decades. The recent remodel of the rear and partial 2nd floor expansion, offers a new dispensary with elevator and stair access. There are currently two tenants, businesses are not included in this offering. City utilities. Further expansion is possible on the 2nd floor which is easily accessible (included in the estimated square footage.) You can only imagine the views across the harbor and out to the ocean. Penobscot Bay boasts some of the best sailing in the North Atlantic. There may never be an opportunity offered such as this in your lifetime. Waterfront Mixed Use Zoning. Real estate only. Businesses not included. Call for details. Rare Offering, Inquire Today
