Each row above is the ordinance’s own rule, written out in words and cited to its section. Where a figure depends on what you build (the kind of building, a conventional or cluster subdivision, an interior or corner lot, or the building’s height), each case is its own line; where it depends on the building height, the cited table says how that height is measured.

How complete is this market? Across 239,083 parcels we answer 96.1% 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 13,550 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 Fairfax County (excl. Vienna and Herndon). Look one of those up and we will tell you which town governs it.

Permitted uses in I-2

AllowedOffice / R&D
Table 4101.1 lists “Office” as P in the I-2 column. P = permitted by right; SE = special exception; SP = special permit; A = accessory only; AP = administrative permit (Table 4101.1).
Not AllowedSTR - Short-Term Rentals

"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.
