Fairfax County, VA · Fairfax County Zoning Ordinance
I-I provides for intense office and office-related uses in a campus-like or institutional setting, generally limited to office and supporting nonresidential uses with enhanced site and building design. Height 65ft. Lot coverage max 30%. Front setback is not a single figure: Table 2104.1 requires the greater of 320ft from the street centerline or 200ft from the lot line, so the distance varies with right-of-way width and no constant is served. Side 200ft (none abutting a railroad). Min lot 20 acres. Section 2104.1.

"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.
