Driveway Paving Cost in Portland (2026)

Yes. A permit is required for any new or altered access to a county road or work in the public right-of-way. Multnomah County charges a $300 application fee, while the City of Portland charges approximately $2.10 per square foot for sidewalk and driveway repairs in the right-of-way, with a typical maximum of $248 per permit.

Portland's persistent rain and shifting clay soils require superior drainage planning and a solid gravel base (typically 8-10 inches). Improper installation can lead to erosion and runoff issues, so contractors often include $500 to $2,000 in additional grading and drainage solutions to ensure longevity.

Asphalt is the budget-friendly choice at $4 to $8 per square foot, while concrete ranges from $6 to $12 per square foot. Although concrete has a higher upfront cost (averaging $10,000–$18,000 for a full project), it lasts 30-50 years compared to asphalt's 15-30 years, often making it more cost-effective over time.

Removing and disposing of an existing driveway in the Portland metro area typically adds $1 to $4 per square foot to the total project cost. For a standard 600-square-foot driveway, homeowners should budget between $600 and $2,400 for tear-out and haul-away services.
