The following yard reductions shall be permitted by direct action of the Zoning Inspector, upon a finding of fact complying with the conditions specified below, and certification of these conditions to the Board of Zoning Appeals, without recourse to variance by action of the Board of Zoning Appeals:
(a) Where there are single nonconforming substandard lots of record at the time of the effectiveness of this Zoning Ordinance or any amendment thereto that were not self-created conditions and that are located in districts permitting residence, the depth of the required rear yard and/or the minimum side yard width may be reduced by up to four (4) inches for each foot by which the lot or record at the effective date of this Zoning Ordinance or amendment thereto was less than l00 feet deep and/or less than fifty (50) feet wide, where this is necessary to provide the minimum site for one single car garage on the site, no more than twelve (12) feet in width by twenty-two (22) feet in length.
(b) Where construction or enlargement of, or addition to, a one-family detached dwelling is to be undertaken on a lot that is substandard by virtue of lot area and/or lot width to a single nonconforming substandard lot of record at the time of effectiveness of this Zoning, Ordinance or amendment thereto located in a district permitting such residences, and application of the yard requirements of the district within which it is located result in a space available for construction that is less than one-half the minimum required floor area (precluding construction of a two- story residence or minimum total floor area), and/or the space available for construction of the residence is less than twenty-two (22) feet in width; then:
(1) The depth of the required rear yard and/or the minimum width of each side yard may be reduced by up to four (4) inches for each foot by which the lot is less than 100 feet deep and/or less than fifty (50) feet in width; and
(2) Any combination of such reductions of side and rear yards may be provided to the point where a minimum available ground area of one-half the minimum required floor area and a minimum construction width of twenty- two (22) feet has been attained but not exceeded.
(c) Side yards, when reduced under subsection (b) hereof, shall be reduced uniformly at both sides. Side yards shall only be reduced, under both subsections (a) and (b) above, when rear yard reduction, within the specified limits, cannot result in the required minimum residential ground floor area, or the minimum garage area, and/or where essential to provide the minimum twenty-two (22) foot residential construction width. Under no condition shall a side yard provided for under the terms of this section, for either a residence or a garage, be less than five (5) feet in width, or less than ten (10) feet in the case of a side yard along a side street lot line, and provided that no rear yard shall be less than ten (10) feet;
(d) Where full application of the reliefs provided above still do not provide the minimum site specified for a single car garage, the permit for construction of the garage shall be denied, and
(e) Where the full application of the reliefs provided above still do not provide a minimum ground floor area of one-half the minimum required floor area and/or a minimum twenty-two (22) foot construction width, on a lot of record meeting the conditions specified above located in a district in which there is no other possible legal use of the ground without variance, the Zoning Administrator shall so certify to the Board of Zoning Appeals, which will accept such certification as proof of a clear and certain hardship on the land warranting relief.
