  1. In R4 Districts, except R4A, R4-1 and R4B Districts, and in R5 Districts other than R5B Districts, for an existing #single-# or #two-family residence# with a #non-complying front yard#, an #enlargement# involving a vertical extension of existing #building# walls facing such #non-complying front yard# is permitted, provided the following conditions are met:
    1. the portion of the #building# which is being vertically extended complies with the height and setback regulations specified for the district in which it is located; and
    2. the #non-complying front yard# where the #building# wall is being vertically extended is at least 10 feet in depth.

    Notwithstanding the above, the provisions of this paragraph, (a), shall also be applicable in R4A Districts in #lower density growth management areas#.

  2. In all districts, for an existing #single-# or #two-family residence# with a #non-complying side yard#, an #enlargement# involving a vertical extension of existing #building# walls facing such #non-complying side yard# is permitted, provided the following conditions are met:
    1. the portion of the #building# which is being vertically extended complies with the height and setback regulations applicable to an R3-2 District;
    2. the #non-complying side yard# where the #building# wall is being vertically extended is at least three feet in width and the minimum distance between such #building# wall and the nearest #building# wall or vertical prolongation thereof on an adjoining #zoning lot# across the common #side lot line# is eight feet;
    3. the #enlarged building# does not contain more than two #dwelling units#;
    4. that there is no encroachment on the existing #noncomplying side yard#, except as set forth in this Section; and
    5. the #enlargement# does not otherwise result in the creation of a new #non-compliance# or in an increase in the degree of #non-compliance#.
Notwithstanding the provisions set forth in paragraphs (a)(1) and (b)(1) of this Section, when an existing #building# has added exterior wall thickness pursuant to Section 23-44 (Permitted Obstructions in Required Yards or Rear Yard Equivalents), such vertical extensions may align with the location of the finished exterior #building# wall of the existing #building#.

In R6, R7 or R8 Districts, for any substantial rehabilitation of one or more #non-complying# multiple dwellings which were in existence prior to December 15, 1961, the City Planning Commission may authorize the existing #open space# on the #zoning lot# to be reduced by not more than five percent and the existing #building floor area# on such #zoning lot# to be increased by not more than five percent, if the Commission finds that such modification of the applicable #bulk# regulations as set forth in Section 54-31 will result in an improved apartment design with adequate access of light and air and an improved circulation system. In the #Special Clinton District#, such authorizations may apply to complying multiple dwellings and may include a five percent increase in #lot coverage# and #floor area#. The Commission, in making the findings above may round out the #floor area# or #lot coverage# increase to the nearest percent.

No increase in the existing density and apartment #floor area# shall be permitted for such #buildings#.

(2/2/11)

If a #non-complying building or other structure# is damaged or destroyed by any means, including any demolition as set forth in this Section, to the extent of 75 percent or more of its total #floor area#, such #building# may be reconstructed only in accordance with the applicable district #bulk# regulations, except in the case of a one- or two-family residence, such #residence# may be reconstructed provided that such reconstruction shall not create a new #non-compliance# nor increase the pre-existing degree of #non-compliance# with the applicable #bulk# regulations. If the extent of such damage or destruction is less than 75 percent, a #non-complying building# may be reconstructed provided that such reconstruction shall not create a new #non-compliance# nor increase the pre-existing degree of #non-compliance# with the applicable #bulk# regulations.

In addition, the alteration of such existing #building# resulting in both the removal of more than 75 percent of the #floor area# and more than 25 percent of the perimeter walls of such existing #building#, and the replacement of any portion thereof, shall be considered a #development# for the purposes of the provisions set forth in Section 11-23 (Demolition and Replacement).

In the event that any demolition, damage or destruction of an existing #building# other than one- or #two-family residences# produces an unsafe condition requiring a Department of Buildings order or permit for further demolition of #floor area# to remove or rectify the unsafe condition, and the aggregate #floor area# demolished, damaged or destroyed including that ordered or permitted by the Department of Buildings constitutes 75 percent or more of the total #floor area# of such #building#, then such #building# may be reconstructed only in accordance with the applicable district #bulk# regulations.

In any case where the applicant alleges that #floor area# is an inappropriate measure of the extent of damage or destruction, and elects to substitute reconstruction costs for #floor area#, an application may be made to the Board of Standards and Appeals to determine the extent of the damage or destruction. Such a #building# may be reconstructed as provided in Section 54-41 (Permitted Reconstruction), substituting the ratio which the cost of reconstructing the damaged or destroyed portion of such #building# bears to the cost of reconstructing the entire #building#, for the percentage of total #floor area#. In determining reconstruction costs, the cost of land shall be excluded.
