Washington County, MN Parking Rules: Driveway Rules (2026)

9(1) sets the surfacing standard for every off-street parking area in unincorporated Washington County. The surface must be durable and dustless, and the area must be graded and drained so surface water does not pool within the parking area. The code allows a narrower exception for residential surfaces: crushed rock or similar dustless treatment is acceptable only for parking accessory to residential structures of up to and including four units. Every other use, including larger residential developments, commercial and industrial sites, must use asphalt, concrete, or another reasonable substitute surface, and that substitute must be approved by the community engineer before it satisfies the code.

Timing matters too: all surfacing must be completed before the structure it serves is occupied, unless the property owner has made other arrangements with the community. 9(3), which sets minimum space dimensions of nine feet by eighteen feet and bars using required parking for open storage or inoperable vehicles.
