(a) Required Setbacks to be Maintained. The required setbacks surrounding an existing building shall not be separated in ownership from that portion of the lot upon which the building is located, and no part shall be considered as providing a required setback for any other existing building on the same or on an adjacent lot. A setback shall not be reduced in any manner to less than the required dimensions for the zoning district in which it is located, and a setback of less than the required dimensions shall not be further reduced in any manner unless otherwise permitted in this Code. Every required setback shall be open and unobstructed from the ground, except for accessory structures as set forth in Title Seven, and as per the parking setbacks in Title Seven.
(b) When one or more buildings, or parts thereof, are constructed or enlarged so as to cross one or more lot lines in the same ownership, all such lots shall be joined into one lot provided all other zoning and subdivision regulations are met.
(c) Required Lot Area to be Maintained. A parcel of land may be subdivided into two or more parcels, provided all lots resulting from such division shall conform to all the lot area and width regulations of the zoning district in which it is located. A nonconforming lot of record that is owned separately from adjoining lots on the effective date of this Code, or as amended, shall not be reduced in any manner that would increase its nonconforming situation.
(d) No single-family dwelling or two-family dwelling shall be constructed on a lot upon which a principal building already exists. New multi-family apartments and townhouse complexes may be erected with more than one principal building to the lot or parcel. Commercial, industrial or institutional buildings may be erected with more than one principal building on a lot or parcel providing they are all under the same ownership. (Ord. 2006-35.
