In any district where dwellings are permitted, a one-family detached dwelling may be erected on any lot of official record on the effective date of this Ordinance, even though such lot does not comply with the lot area and width requirements of the district in which it is located, provided said lot has a minimum of forty (40) feet frontage on a public street; and further provided the following conditions are complied with:
(a) In any district where dwellings are permitted, two (2) inches may be deducted from the required minimum width of each side yard and four (4) inches from the required sum of minimum widths of both side yards for each foot that the lot is narrower than the required width for the district. In no case, however, shall any side yard be narrower than three (3) feet.
(b) For lots having a depth of less than 100 feet, the depth of the rear yard need not exceed twenty-five percent (25%) of the total depth of the lot, but shall not be less fifteen than feet. (Ord. 07-8. Passed 3-19-07.)
