23-22 Maximum Number of Dwelling Units

In all districts, as indicated, the maximum number of dwelling units shall equal the maximum residential floor area permitted on the zoning lot divided by the applicable factor in the following table. In R1 through R5 Districts, no rooming units shall be permitted and any dwelling unit shall be occupied by only one family. Fractions equal to or greater than three-quarters resulting from this calculation shall be considered to be one dwelling unit.

For the purposes of this Section, where a floor area ratio is determined pursuant to Section 23-151 (Basic regulations for R6 through R9 Districts), notwithstanding the height factor of the zoning lot, the maximum residential floor area ratio shall be 2.43 in an R6 District within 100 feet of a wide street, 3.44 in an R7 District and 6.02 in an R8 District. In an R6 District beyond 100 feet of a wide street, the maximum residential floor area ratio shall be as specified in Section 23-151, or 2.2, whichever is greater.

For affordable independent residences for seniors, there shall be no applicable dwelling unit factor.

For zoning lots with buildings containing multiple uses or multiple buildings with different uses, special provisions are set forth in Section 23-24 (Special Provisions for Buildings Containing Multiple Uses) to determine the maximum number of dwelling units permitted.
