SEC. 920. DENSITY OF RESIDENTIAL USES IN MB-R AND MB-NC DISTRICTS.

   (a)   Number of Dwelling Units Permitted and Required. The maximum allowable and minimum required number of dwelling units in each development block in MB-R and MB-NC-2 and MB-NC-3 Districts shown in Figure 2, is as described in Table 920 below, except as provided in Subsection (b). The term "dwelling unit" is defined in Section 102.7. Dwelling unit sizes shall be determined in the manner provided in the Mission Bay Plan. In MB-NC-S Districts, there shall be no minimum required number of dwelling units, and the maximum shall be the number of dwelling units which can be accommodated in a building or buildings on the block or lot which conform to the applicable building standards of this Article and the Design Guidelines of the Mission Bay Plan.

   (b)   Assignment of Densities to Lots as Development Blocks are Subdivided. As each development block is subdivided and re-subdivided from time to time pursuant to the provisions of the Subdivision Code it shall be established to the satisfaction of the Zoning Administrator that the number of dwelling units to be assigned to each lot in the subdivision can be accommodated in a building or buildings which conform to the applicable building standards of the district and the design guidelines of the Mission Bay Plan.

   (c)   Transfer and Increase of Residential Densities. 

      (1)   Transfer. The number of dwelling units on a specific development block, as defined in Section 996(b)(1), may be up to 10 percent greater or less than the number specified in Table 920 provided that the greater or lesser number of units is compensated for by an equal decrease or increase in units in another development block or blocks. When more than one development block or lot are aggregated to form a single development project, as defined in Section 996(b)(10), the number of dwelling units assigned to particular blocks or lots may vary by more than 10 percent from the numbers listed in Table 920 provided that the total number of dwelling units in the single development project equals the total of the numbers specified for all the blocks and lots in the single development project.

      (2)   Increase. The total number of dwelling units initially authorized in Table 920 for Affordable Housing Development Blocks may be increased by 366 units, and for all other development blocks by 268 units, pursuant to the procedures set forth in Subsection (d)(1) below. The term "Affordable Housing Development Blocks" refers to those development blocks listed in Table 920 which contain the letter "A" in the block number.

   (d)   Limitations on Transfer of Densities. The following limitations on the transfer of density shall apply:

      (1)   As a condition of approval of a transfer of dwelling units or an increase in the number of dwelling units in any development block or lot, it shall be established to the satisfaction of the Zoning Administrator that the increased number of units can be accommodated in a building or buildings on the block or lot which conform to the applicable building standards of this Article and the design guidelines of the Mission Bay Plan and that the guidelines on unit size can be met.

      (2)   The Zoning Administrator may deny any request for a transfer of density if, at the time of the request, the total number of dwelling units constructed or under construction on all blocks or lots on which density has been increased or decreased, as provided in Subsection (c) above, is 200 units less than the total number of units initially authorized in Table 920 for all blocks or lots on which the density has been increased or decreased.

   (e)   Recording Transfers of Density. As the number of dwelling units permitted and required on each development block is modified from time to time, as permitted in this Section, a new table, to be titled "Table 920-R, Residential Density Table with Density Transfers," shall be prepared to reflect the modifications. A revised table shall be submitted as part of the request for density transfer, approved by the Zoning Administrator as part of the transfer approval, and published in a form suitable for insertion in the Planning Code.
