Where yards are below the requirements set for the district in which the building and lot are located, and which were owned separately from all other parcels of land at the time of the enactment of this Zoning Code or any subsequent amendment thereof, and are still so owned, the building may be maintained or altered, but may not be enlarged in ground floor area unless the yard requirements comply with the regulations set forth in this chapter, as amended.
