PDRDPPlanned Development - Research and Development Park Legacy District
Loudoun County, VA · Loudoun County Zoning Ordinance
Planned Development - Research and Development Park Legacy District is an Employment Zoning District of the Loudoun County Zoning Ordinance. Its permitted uses are set by the ordinance's own Principal Use Table and its dimensional standards by its Chapter 2 district table; both are cited on every line below. Figures are deliberately left out of this description so that it can never contradict a standard that carries a citation -- read the standards, not this paragraph, for numbers.
Development standards in PDRDP
Maximum height
Set by how far the building is set back: 45 ft, and up to 100 ft where it is set back further from streets and from the boundaries of districts with lower height limits, as set forth in Sec. 2.02.05.08 — see 2.02.05.08
A standard shown as "set by" is banded in the ordinance — it depends on what you build or on the lot itself, so no single figure is true for the whole zone. The cited table is the authority; read the tier that matches your intended structure.

How complete is this market? Across 107,655 parcels we answer 85.5% of the 6 questions this site is built to answer, each with a source you can check. The rest are shown as “not recorded” rather than filled in — we would rather be short than wrong. A further 18,974 properties inside the county line are zoned by an incorporated town with its own ordinance, not by the county, so this county ordinance does not govern them and they are not counted above or below — which is why we publish this market as Loudoun County (excl. incorporated towns). Look one of those up and we will tell you which town governs it.

"Conditional" means the use generally requires a public hearing or special-exception approval — a very different timeline and risk profile from a by-right permit.
