If the dwelling cannot be designed, located, constructed and maintained in compliance with § 154.2.117 Accessory Dwellings, it shall not be considered an accessory dwelling, but may be considered an additional single-family dwelling on one lot if it is designed, located, constructed and maintained in compliance with the following standards:
(1) Additional single-family dwellings on one lot shall comply with the density regulations for the zoning district in which it is to be located. Each single-family dwelling unit on one lot shall be one unit used in the density calculation;
(2) Additional single-family dwellings on one lot shall be served by separate and independent infrastructure including, but not limited to, a water supply and septic system approved by the Virginia Department of Health;
(3) An additional single-family dwelling on one lot shall be located and separated from other single-family dwellings with their accessory structures a distance equal to the minimum required setbacks as if property lines existed between the additional single-family dwelling and other single-family dwellings with their accessory structures and shall be laid out in such a manner as to permit subdivision into separate lots as provided for in Chapter 156: Subdivision; and
(4) If a property containing additional single-family dwellings seeks approval for one or more of the single-family dwellings to be subdivided from the base parcel, the applicant shall first seek approval of a preliminary subdivision plat and phasing plan for the subdivision of all single-family dwellings located on the base parcel. After the approval of a preliminary subdivision plat and phasing plan has been obtained, one or more of the single-family dwellings located on the base parcel may be subdivided individually in compliance with the approved preliminary subdivision plan and phasing plan.
