Cost to Pergola / Gazebo Installation in Portland, OR (2026)
If you’re budgeting a pergola / gazebo installation in Portland, most projects run $1,692-$13,536, 13% above the $5,500 national average. What moves that number most is usually one thing: Size. On its own it can swing the cost by $500 - $20,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Buy a pergola kit instead of sourcing raw lumber. Kit lumber is pre-cut, pre-notched, and often pre-drilled. The time savings in cutting and fitting makes the modest kit premium worthwhile.
