Summary
Whatcom County splits short-term lodging into two zoning categories by host presence. A "vacation rental unit" is, by definition, a rental where the owner is not on site during the stay; an owner-occupied rental where at least one owner sleeps there overnight is instead classified as a bed and breakfast, with its own room caps.
"Vacation rental unit" means a single-family dwelling unit or accessory dwelling unit that, for compensation, is rented as a single unit used to lodge individuals or families for a period of less than 30 days and where the owner is not present in the rented unit during the rental period. Individual sleeping rooms shall not be rented individually. ... "Bed and breakfast establishment" means a privately owned dwelling that is the primary residence of the owner and in which, for compensation, one to two rooms are used as sleeping units to house or lodge individuals or families for periods of less than 30 days as transient visitors with or without limited food service... At least one owner shall be present overnight when a guest room is rented.

Full Breakdown
220 defines a vacation rental unit as "a single-family dwelling unit or accessory dwelling unit that, for compensation, is rented as a single unit used to lodge individuals or families for a period of less than 30 days and where the owner is not present in the rented unit during the rental period," and bars renting individual sleeping rooms separately: the whole unit must go to one party. 070, the same overlay-district treatment applied to bed and breakfast establishments. In practice, an operator who wants to be off-site during the rental must structure and advertise the stay as a vacation rental unit renting the whole home or ADU; an operator who plans to remain overnight while renting a spare room falls instead under the bed-and-breakfast definitions and their lower room caps.
Violations & Fines
Operating a rental that does not match its declared category, such as renting individual bedrooms separately out of what is classified as a vacation rental unit, or renting guest rooms in a claimed bed and breakfast without an owner present overnight as WCC § 20.97.020 requires, misclassifies the use under Whatcom's zoning code and is enforceable as a zoning violation under Chapter 20.94 WCC. Inside the Lake Whatcom Watershed Overlay District, operating a vacation rental unit without the conditional-use approval required by WCC § 20.51.070 is a separate violation.
