In an R2 district, no building or use shall be permitted, except for the following:

   A.   Any use permitted in the R1 district.

   B.   Accessory building(s) or structures permitted in the R1 district. (Ord. 2640, 5-23-1995)

In an R2 district, special uses may be allowed by the zoning board of appeals in accordance with chapter 18 of this title, as follows:

   A.   Any special use permitted in the R1 district. (Ord. 2640, 5-23-1995)

In an R2 district, no more than five residential units per acre may be erected. (Ord. 2640, 5-23-1995)

In an R2 district, no building may be erected or altered on a lot which does not comply with the following regulations:

   A.   Lot Area: Except as provided in subsection C of this section, the minimum lot area shall be eight thousand seven hundred twelve square feet.

   B.   Lot Width: Except as provided in subsection C of this section, the minimum lot width shall be no less than the average width of all lots of record zoned R2 which are within the same block, consisting of both sides of the street and measured by the closest intersecting street on each side; provided, however, that each said resulting lot shall have a width of not less than fifty feet and no lot shall be required to be greater than seventy feet in width, and that corner houses shall be deemed to front on their respective north/south streets.

   C.   Exception To Lot Area And Lot Width Requirements: The limitations set forth in subsections A and B of this section shall not apply to or prohibit the restoration, reconstruction, or replacement of an existing single-family detached dwelling or an existing accessory structure on a single lot or lot of record which does not comply with the lot area or lot width requirements in subsections A and B of this section. Where an unimproved lot meets the fifty foot lot width minimum and required lot area, that lot shall be considered buildable, provided recognizing said lot as buildable does not create a nonconforming condition on an adjacent lot. Additionally, there shall be no limit on the length of time a vacant lot or lot of record can remain vacant and still be considered buildable, if the vacant lot is the result of the demolition of an existing dwelling. The burden of proving that a dwelling existed on the nonconforming lot rests solely on the person invoking this provision. The exceptions stated in this subsection shall not be construed so as to apply to any other regulations stated elsewhere in this code. (Ord. 3122, 8-8-2005)
