Heritage areas contain a concentration and continuity of buildings and structures with similar heritage values. Heritage areas contain contributing buildings and structures which have not been listed in SCHED1-Heritage buildings or SCHED2-Heritage Structures but have significant heritage value when considered as a collection. Heritage buildings and heritage structures may be located within heritage areas, as well as buildings and structures that do not contribute to the heritage values of the area, which are identified as non-heritage in SCHED3-Heritage Areas. Demolition rules do not apply to non-heritage buildings and structures.
