Building a boat dock costs $4,074 to $26,021 for most homeowners, with Angi publishing a $15,048 national average from 178 reported projects.1 HomeAdvisor publishes the same average and normal range, and both give an overall span of $1,000 to $65,000.2 Fixr separately publishes a $15,000 national average for a 360 sq. ft. stationary L-shaped wood dock with a cedar deck, within a $7,000 to $25,000 average range.3 Prices below are national averages*.

*National averages, not local quotes. Angi figures are from a 2026 guide updated September 2026, HomeAdvisor figures are from a 2025-data guide updated June 2026, and Fixr figures are from a guide updated January 2025. Your price depends on dock type, size, materials, water conditions, and site prep.
