§ 112. Front-yard setback for dwellings.

The front-yard setback requirements of this ordinance for dwellings shall not apply on any lot where the setback of an existing building or buildings located wholly or in part within 100 feet on each side of such lot within the same block and zoning district and fronting on the same side of the street is less than the required minimum setback. In such cases, the setback on such lot may be less than the required setback but not less than the average of the setbacks of the aforementioned existing buildings.
