How much does it cost to build a deck in 2026? Detailed pricing by material, including labor, hardware, and permits.
The decking surface (boards) makes up 30-40% of total cost. Prices per square foot for boards only:
The framing — joists, beams, posts, and ledger board — accounts for 25-35% of total cost. Framing is almost always pressure-treated lumber regardless of decking material.
Deck labor runs $8 – $15/sq ft for a simple ground-level PT wood deck. Elevated decks (3+ feet off ground) run $15 – $22/sq ft due to stairs, railing, and more complex framing. Composite installation costs roughly the same as wood for labor.
Most jurisdictions require a building permit for any attached deck or a deck more than 30" above grade. Permit fees range from $100 – $500 and typically require a site plan and structural details.
