D.C. Mun. Regs. tit. 11, r. 11-K308
The maximum non-residential FAR for the entire USN zone is 5.5.
Until a 0.5 FAR of residential uses have been developed within the entire USN Zone, as evidenced by a certificate or certificates of occupancy for residential uses, no certificate of occupancy for non-residential uses may be issued that would result in a non-residential FAR for the entire USN zone of greater than 3.0.
Until 1.0 FAR of residential uses have been developed within the entire USN zone, as evidenced by a certificate or certificates of occupancy for residential uses, no certificate of occupancy for non-residential uses may be issued that would result in a non-residential FAR for the entire USN zone of greater than 4.0.
The minimum residential FAR may be apportioned between the single building north of H Street and the single building south of H Street, provided that the aggregate residential floor area is not decreased.
The minimum residential density shall not include the density dedicated to residential parking located above the level of the platform.
