Parts 4 (general regulations), 5 (parcel areas) and 6 (parking) of the bylaw also apply; short-term rental isn't a use the zone lists, so ask the City before renting a home by the night.

Site-specific exceptions listed in the bylaw by legal description can add or change uses for one property, and development permit areas, the ALR and building rules apply on top. Confirm with the City of Cranbrook's planning department before you buy or build.
