Minimum Lot Area and Lot Width for Residences

For all zoning lots containing residences, the minimum lot area and lot width requirements set forth in the table in this Section shall apply, which shall vary by building height. Where two or more buildings that are single- or two-family detached or semi-detached residences are located on a zoning lot, the applicable minimum lot area requirement shall be multiplied by the number of such buildings on the zoning lot.

The lot width requirements set forth in this Section shall be applied as set forth in the definition of lot width in Section 12-10 (DEFINITIONS), provided that the applicable lot width, in feet, set forth in the table shall be met along at least one street line of the zoning lot or, for corner lots, along each intersecting street line. No residence, or portion thereof, shall be permitted between opposing side lot lines where such lot lines would be nearer to one another at any point where such residence is located than the applicable minimum lot width, in feet, set forth in the table.

However, one single-family detached residence or, where permitted, one single or two-family residence, may be built upon a zoning lot consisting entirely of a tract of land, that:

(a)        has less than the minimum lot area or lot width required pursuant to this Section; and

(b)        was owned separately and individually from all other adjoining tracts of land, both on December 8, 2005, and on the date of application for a building permit.

In all cases, the density regulations of the applicable district shall remain in effect, except that the factor for determining the maximum number of dwelling units shall be 1,000 in R3A and R4A Districts, 1,140 in R3X Districts, and 685 for semi-detached residences in R3-1 and R3-2 Districts.
