Deck Building in Oregon is 16% above the national average of $9,045. This is primarily due to higher labor costs and stronger demand in Oregon.
Oregon experiences a mild marine climate west of the Cascades with wet, cool winters and dry summers, shifting to a cold semi-arid continental climate east of the mountains. Persistent rainfall from October through May tightens exterior building windows in the Willamette Valley and coast, while the Bend and Pendleton areas face real snow and freeze exposure. For deck building projects specifically, this means timing and material selection are key factors in both cost and quality.
Oregon's costs are close to the national average, reflecting a balanced supply-demand dynamic in the local construction market.
