In any Residence A-2 District as indicated on the Building Zone Map, no building or other structure shall be erected, altered or used and no land shall be used or occupied for any purpose except one or more of the following:
Any use permitted in a Residence A-1 District.
A one-family detached dwelling for one housekeeping unit only; provided, however, that the Board of Appeals, upon an appeal from an order or decision made by the Inspector of Buildings and if it deems such action wise and if it shall appear to the Board that such action will tend to preserve the standard and character of the neighborhood, may authorize a variation in the use of a one-family dwelling existing at the time of the adoption of this Article so that such dwelling may be altered and improved and facilities added for a second housekeeping unit. In all such cases the petitioner, as a condition precedent to the privilege herein granted, shall present adequate plans setting forth the changes and improvements to be made and shall have secured the written consent and approval of at least three of the following property owners:
The owner of the lot on either side of the petitioner's property.
The owner of the lot adjacent in the rear of the petitioner's property.
The owner of the lot directly across the street therefrom. Where the petitioner is the owner of a lot on either side, in the rear or across from the property for which a variation is requested, such lot shall be omitted, in which case written consent and approval shall be secured from the owner of the property next to that owned by the petitioner. In case there are two or more lots adjacent in the rear or sides of the petitioner's property, the owner of the lot which abuts the greater length on the petitioner's property shall be deemed the owner of the lot adjacent to the petitioner's property, as used in this section.
In the case of an appeal for a variation involving a dwelling situation on a corner lot or so located that the obtaining of the exact numerical assents of the owner above enumerated is unreasonable or impossible, the Board of Appeals may grant the variation, provided that the consents of the property owners are obtained substantially in accordance with the principals herein set forth as may be determined by the Board of Appeals. The power to authorize such variation of the use of existing dwellings shall be within the sound discretion of the Board of Appeals, and no variation in use shall be granted unless it shall be clear that the relief requested will not be detrimental to the best interests of the vicinity and will be in harmony with the general purpose and intent of this chapter. Each case shall be considered on its own merits, and no case shall raise a presumption in favor of any other case. No decision of the Board of Appeals shall be considered as changing or affecting the zoning of any Residence A-2 District.
