How Much Does a Deck Cost in 2026?
Deck costs are driven by three decisions made early in the process: size, material, and configuration. A simple rectangular pressure-treated deck at grade can be built for $8,000–$15,000. Switch to composite decking or add a second level with stairs and railings, and you can double or triple that number. Material choice alone shifts the per-square-foot cost from $15 (basic pressure-treated) to $50+ (composite or hardwood) — and that difference compounds quickly as the deck grows.
After materials, your location determines more of the final cost than any other factor. Deck labor in coastal markets costs 35–45% more than the national average, and permitting in high-activity cities adds both fees and wait time. BuildCost pulls state-level contractor pricing data to calibrate your estimate for your market — not a national average that can be off by thousands.

What Affects the Cost of a Deck?
- •Decking material: Pressure-treated pine is the lowest-cost option at $15–$25 per sq ft installed. Composite decking (Trex, TimberTech, Fiberon) runs $25–$50 per sq ft installed but requires no staining and carries longer warranties. Hardwoods like ipe or tigerwood are premium options at $30–$60 per sq ft installed.
- •Size and configuration: Each additional 100 sq ft adds approximately $3,000–$8,000 depending on material grade. Multi-level decks, angles, curves, and built-in features (benches, planters, pergolas) add disproportionate labor cost compared to simple rectangular decks.
- •Labor and zip code: Deck labor rates vary 30–50% by market. California, New York, and the Pacific Northwest run 35–45% above national averages. Texas, the Midwest, and the Southeast run at or below average. Scheduling in the off-season (late fall or winter in non-freezing climates) can reduce rates 10–15%.
- •Footings and height: Ground-level decks with surface-mounted footings cost less. Elevated decks requiring concrete piers dug below frost line add $200–$500 per footing. A deck elevated 8+ feet off the ground requires structural posts and beams that significantly increase framing costs.
- •Railings and permits: Code-compliant railings for elevated decks run $50–$150 per linear foot depending on material (pressure-treated wood vs. aluminum vs. cable railing). Permit fees range from $150 to $600+. Complex railing systems are one of the most common sources of cost overrun in deck bids.
Deck Cost — Frequently Asked Questions
How much does a deck cost?
A wood deck typically costs $8,000–$30,000+ depending on size, material, and location. A small pressure-treated deck (100 sq ft) runs $8,000–$15,000. An average 300 sq ft deck with composite decking averages $18,000–$28,000. A large multi-level deck with built-in features like benches, lighting, or a pergola can exceed $40,000. Composite decking costs 50–100% more than pressure-treated wood upfront but requires far less long-term maintenance.
How much does a deck cost in Texas?
In Texas, a deck typically costs 5–15% below national averages in most markets. A 300 sq ft pressure-treated deck in Dallas–Fort Worth or Houston averages $14,000–$22,000. Composite decks in Texas run $20,000–$30,000 for the same size. Heat and UV exposure in Texas make composite or hardwood decking worth the premium over pressure-treated pine, which can warp and crack faster in the southern climate.
How long does it take to build a deck?
A standard deck build takes 1–3 weeks from permit approval to completion. The permit process takes 1–4 weeks depending on your municipality. Footings must cure 24–48 hours before framing begins. A straightforward ground-level deck can be done in 3–5 days by an experienced crew; a multi-level deck with stairs and railings takes 1–2 weeks of active construction.
Does a deck require a permit?
Most decks require a building permit, especially those attached to the house or elevated more than 30 inches off the ground. Freestanding ground-level decks may be exempt in some jurisdictions but check with your local building department before assuming. Permits ensure the footings, framing, and railings meet structural and safety codes — and an unpermitted deck can complicate a home sale.
How do I find a contractor for a deck?
Get at least 3 bids from licensed deck contractors or residential carpenters with verifiable deck projects. Ask specifically about footing depth (frost line compliance in your area), decking material warranties, and railing code compliance. Confirm permits are included in the bid. Thumbtack and the North American Deck and Railing Association (NADRA) are good resources for finding qualified local deck builders.
