Deck build cost guide
Data snapshot 2026-09 · Updated 2026-09-12 · HomeTrueCost
A 320 sqft composite deck runs $13,000–$20,000 professionally built in 2026; composite runs about 40% more than pressure-treated all-in. This guide covers the state table, the elevated-deck premium, and frost-depth footing variables.

What moves the number
01
Size and boards
Area scales linearly; composite boards roughly double material vs pressure-treated, exotics more. Rail length matters.
02
Height premium
Elevated decks (×1.25) need deeper footings, beams, stairs, and full rail — ground-level platforms skip most of that.
03
Footings and frost
Frost-depth footings and soils vary by state; helical piles vs dug footings change the base-work line.
04
Permits
Most jurisdictions permit attached and elevated decks. State-indexed allowance included; cities set the real fee.
FAQ
How much does a deck cost in 2026?
A 320 sqft composite deck typically runs $13,000–$20,000 pro-built. Pressure-treated starts near $9,000; composite runs about 40% more all-in; elevated structures add about 25%.
What drives deck cost the most?
Size plus board material, then height — footings, beams, stairs, and rail for elevated decks. Permits and frost-depth footings vary by state.
Is this quote a contractor bid?
No — a planning estimate. Soil, frost depth, and ledger conditions vary; get 3 local bids.
