Where side yards are narrower than required for the district in which the building and lot are located, which building and lot were owned separately from all other tracts of land on the effective date of this Zoning Code or any amendment thereto, and are still so owned, the building may be maintained or altered but may not be enlarged in width until the total width of the side yards complies with this Zoning Code.
