Aurora, CO Parking Rules: Driveway Rules (2026)

The Aurora Unified Development Ordinance limits how much of a single-family or two-family front yard a driveway can cover: 40 percent of the total front yard area, or 50 percent on wedge-shaped lots. Driveways must be at least 18 feet long, and parked vehicles can't encroach onto public or private streets or sidewalks. Surfacing must be concrete, asphalt, or brick or stone pavers wherever the driveway abuts a paved public right-of-way. That paving requirement drops away on lots abutting unpaved streets in residential zones or unpaved rights-of-way in open, natural, or agricultural districts, those driveways instead must meet Public Works construction, drainage, and containment standards. Pre-existing surfaces from before July 21, 2012 are grandfathered as nonconforming but can't be enlarged.
