Fairfax County, VA · Fairfax County Zoning Ordinance
PDH-16 is a subdistrict of the Planned Development Housing district. Its maximum residential density is set by Fairfax County Zoning Ordinance Table 2105.1 and its minimum open space by Table 2105.2; both are shown in the development standards. Section 2105.1 states no minimum lot area or width for planned districts and leaves building height, setbacks, and floor area ratio to the general and design standards for planned developments, so no by-right figures for those are published for this district. Development is governed by an approved development plan.
