The district requirements with respect to yards and other open spaces shall not apply in cases where the conversion is a part of a planned development project meeting the requirements specified in Chapter 1181. Such yard and other open space requirements shall also not apply in cases where the conversion will not involve any major exterior structural changes; and there is a shortage in the required dimensional area of each of not more than two such requirements as to yards and other open spaces, or in case the conversion will result in a lot area per dwelling unit or family at least twenty percent (20%) greater than required for new buildings in the district.
