- The subject site or lot:
a. Is located adjacent to a residentially zoned property or is located next to a residential use; and
b. Has substantial existing development on the subject site; and
The sizes of any and all additions or structures to be added to the subject site or lot shall not exceed fifty percent of the square footage of the existing structures on the subject site or lot and for which development permits were obtained prior to February 19, 2001; and
The aggregate total square footage of all additions or new structures to be added to the subject site or lot shall not exceed fifty percent of the square footage of the existing structures on the subject site or lot as of February 19, 2001; and
