(Code 1981, § 8-5-181)

If two or more adjoining and vacant lots with continuous frontage are in a single ownership at any time after the adoption of this chapter, and those lots individually are less than the lot width requirements for the zone in which they are located, those groups of lots shall together be considered as a single lot or shall be grouped into several lots of minimum permitted size, and the resulting lot or lots shall be subject to the dimensional requirements of this chapter.

In such cases, the setback on that lot may be less than the required setback but not less than the average of the existing setbacks on the aforementioned lots, or within ten feet of the street right-of-way, whichever is greater.
