The conversion of any building into a dwelling, or the conversion of any dwelling so as to accommodate an increased number of dwelling units of families, shall be permitted only within a district in which a new building for similar occupancy would be permitted under this chapter, and only when the resulting occupancy will comply with the requirements governing new construction in such district, with respect to minimum lot size, lot area per dwelling unit, percentage of lot coverage, dimensions of yards and other open spaces, and off-street parking. Each conversion shall be subject also to such further requirements as may be specified hereinafter within the chapter applying to such district. The aforesaid requirements with respect to lot coverage, yards, and other open spaces shall not apply in case the conversion will not involve major exterior structural changes and in case:
(a) There is either a shortage of not more than ten percent (10%) in the required dimensions or area of each of not more than two such requirements as to coverage, yards, and other open spaces; or
(b) The conversion will result in lot area, per dwelling unit or family, at least twenty percent (20%) greater than required for new buildings in the district.
