The 2026 Cost of Building a Deck in the USA
Materials, labor and regional pricing broken down for pressure-treated, cedar and composite decks.
What a deck really costs in 2026
The national average for a professionally built deck in 2026 lands between $32 and $65 per square foot installed. A standard 16x20 (320 sq ft) deck therefore runs roughly $10,240 on the low end to $20,800 on the high end, before railings, stairs, or premium finishes.
Material choice is the single biggest cost lever. Pressure-treated pine remains the budget favorite at $22–$32/sq ft installed. Western red cedar sits in the middle at $30–$45. Capped composite (Trex, TimberTech, Fiberon) ranges from $45–$75/sq ft, and premium PVC or exotic hardwoods like Ipe can push past $90.
Cost breakdown for a 320 sq ft composite deck
A realistic 2026 line-item budget for a mid-range composite build:
- Decking boards & fasteners: $6,400
- Pressure-treated framing & joist tape: $2,100
- Concrete footings and post hardware: $850
- Composite railing system: $2,400
- Stairs (3 risers): $1,100
- Permit & inspection: $250–$650
- Labor (35–45 hours crew): $4,800
Regional multipliers you should plan for
Coastal California and the NYC metro run 35–45% above the national average because of labor rates and stricter code. Texas, Florida and the Southeast usually sit 5–10% below average. Mountain West states are close to par but material freight can add 3–5%.

Where to save without regretting it
Stick with a rectangle. Every angle, cutout, or picture-frame border adds labor hours and waste factor. Keep railings simple — swapping glass balusters for black aluminum saves $18–$25 per linear foot and still looks premium. If you're set on composite, choose a mid-tier grooved board with hidden clips rather than the flagship line; the color and warranty gap is small, the price gap is not.
