How much does it cost to build a deck?

A new deck typically costs $30 to $60 per square foot installed. A common 200 sq ft deck lands around $6,000 to $12,000, but the range is wide because the material and size do most of the work. A ground-level pressure-treated deck sits at the low end; a large, elevated composite deck with railing and stairs sits at the high end.

Frequently asked questions

How much does it cost to build a deck?

Most new decks cost about $30–$60 per square foot installed, so a typical 200 sq ft deck runs roughly $6,000–$12,000. Pressure-treated wood is the cheapest option and composite or PVC the priciest. Height, railing, and stairs add to the total — enter your details and ZIP above for a local estimate.

Is a wood or composite deck cheaper?

Pressure-treated wood is cheaper to build (around $15–$32 per sq ft installed) than composite ($25–$60 per sq ft). Composite costs more up front but needs almost no maintenance and lasts longer, so it can be cheaper over 20+ years when you factor in staining and board replacement.

Does the estimate include labor?

Yes. These are installed prices — materials, framing, fasteners, and professional labor. Building it yourself removes the labor portion (often half the cost) but adds the work of footings, framing, and permits.

Do I need a permit to build a deck?

Usually yes, especially for raised or elevated decks and anything attached to the house. Permit fees are commonly $50–$500, and an inspection of the footings and ledger is typical. Check with your local building department.

What adds the most to deck cost?

Size and material are the biggest drivers. After that: elevation (a second-story deck needs taller posts and more framing), railing (roughly $30–$80 per linear foot), stairs, and built-in features like benches or lighting.
