The front yard requirements of this chapter for dwellings shall not apply to any lot where the average setback of existing buildings located wholly or partially within 100 feet on either side of the proposed dwelling and on the same side of the street in the same block and use district as the lot is less than the minimum required front yard depth. In that case the front yard on those lots may be less than the required front yard but not less than the average of the existing front yard on the aforementioned lots, or a distance of 15 feet from the edge of the street right-of-way, whichever is greater.
