Loudoun County, VA Parking Rules: Driveway Rules (2026)

F sets Loudoun's on-lot parking standard for single-family detached homes in Suburban Zoning Districts. The core rule is simple: all vehicle parking on the lot must sit on a paved parking surface, with only one exception, temporary unpaved parking is allowed while a vehicle is actively loading or unloading, not for regular use. The ordinance defines 'paved parking surface' broadly to include the driveway used to reach the parking area, and it accepts asphalt, poured or precast concrete, brick, stone, gravel, grasscrete, or any other permeable or impermeable surface; a fully enclosed garage doesn't count toward or against this calculation.

Beyond just requiring pavement, the rule caps how much of the front yard can be covered: paved surface between the dwelling and any street can't exceed 30% of that area. Three carve-outs let that 30% cap flex upward: a paved area no larger than 25 feet by 18 feet serving two side-by-side spaces directly off the street; a similarly sized paved area plus a turn-around up to 162 square feet on lots with primary access from a collector or arterial road; and any driveway on a pipestem lot, which by definition needs a long access strip. Toward the rear lot line, the cap drops to 25% of that area. 06's purpose.
