(Other) Vessel Containing Dwelling Unit
Definition – Per SMC 23.60A.214.D (strictly, NOT an SMC definition)
This section is a bit complicated so we will break it down as best we can. For the purpose of this website, we are discussing the section of the Seattle Municipal Code that is defined in section 23.60A.214.D “Other Vessels Containing Dwelling Units.” The purpose is to describe a floating residence that is NOT a “Recreational Vessel” but meets other criteria specified in that section of the code. This is important to understand as they are regulated differently than Floating On Water Residences, House Barges, and Recreational Vessels for the purpose of residential use.
NOTE: There is not a definition in the SMC for a “Vessel Containing Dwelling Unit,” however, there are definitions for “Vessel” and for “Dwelling Unit” and these are shown below;
“Vessel” means ships, boats, barges, or any other floating craft that are designed and used for navigation and do not interfere with the normal public use of the water, including historic ships that do not have means of self-propulsion and steering equipment and house barges.
“Dwelling unit” means a room or rooms, located within a structure or vessel, designed, arranged, occupied, or intended to be occupied as living accommodations independent from any other household. The existence of a food preparation area within the room or rooms shall be evidence of the existence of a dwelling unit.
These particular types of floating residences are unique because of their regulations.
