For purposes of calculating the maximum density for group housing as set forth herein, the number of bedrooms on a lot shall in no case be considered to be less than one bedroom for each two beds. Where the actual number of beds exceeds an average of two beds for each bedroom, each two beds shall be considered equivalent to one bedroom.


The rules for calculation of dwelling unit densities set forth in Section 207.1 shall also apply in calculation of the density limitations for group housing, except that in NC Districts, any remaining fraction of ½ or more of the maximum amount of lot area per bedroom shall be adjusted upward to the next higher whole number of bedrooms.


The group housing density in all RTO Districts and all NCT Districts, as listed in Section 702.1(b), shall not be limited by lot area, but by the applicable requirements and limitations elsewhere in this Code, including but not limited to height, bulk, setbacks, open space, and exposure, as well as by the Residential Design Guidelines in RTO districts, other applicable design guidelines, applicable elements and area plans of the General Plan, and design review by the Planning Department.
