(a) In this chapter, district and lot size requirements are expressed in terms of:

(1) Minimum district size

(2) Minimum lot area

(3) Minimum lot width

(b) Minimum lot area and minimum lot width requirements are for conventional subdivision lots; for open space subdivision lots, refer to section 24.1-402.

(c) Where no minimum district size is specified, the minimum lot area and lot width requirements shall define the minimum district size.

(d) Where a minimum district size is specified for a particular zoning classification, additional lands, which standing alone do not meet the minimum district size requirements, may be rezoned to such classification if such lands are contiguous to the zoned district, if the rezoning would be consistent with the adopted comprehensive plan, and provided that with the addition of such land the total contiguous area in the given classification will equal or exceed the required minimum district size.

(e) Unless otherwise specified in this chapter, all uses permitted by right or by special use permit shall be subject to the minimum lot size requirements specified for a given district.
