In pre-1978 buildings that contain a mix of target housing and zero-bedroom dwellings, the RRP rule applies only to renovations performed in target housing and common areas. Common areas are those portions of a property generally accessible to residents/users of target housing, and can exist on both the interior and exterior of the building. They include, but are not limited to, hallways, stairways, laundry and recreational rooms, playgrounds, community centers and boundary fences.
Therefore, in a building that contains both multi-room apartments (i.e., target housing) and zero-bedroom dwellings (i.e., non-target housing), the RRP Rule applies to renovations in the multi-room apartments and to renovations on those portions of the property that are generally accessible to all residents/users of the building. The RRP rule does not apply to work performed in the zero-bedroom dwellings.
