A new deck is one of the highest-return outdoor projects you can take on, with composite builds recouping around 65 percent of cost at resale according to the Cost vs Value Report. The headline question every homeowner asks first is how much is a deck, and the honest answer ranges from 15 to 60 dollars per square foot installed. That is a 4x spread, driven by material, framing complexity, height off the ground, and your local labor market. Knowing what pushes a quote up or down is the difference between a 10,000 dollar build and a 30,000 dollar build for the same square footage.

Average Deck Cost in 2026
For a standard 12×16 (192 sq ft) deck, expect these ranges installed:
- Pressure-treated pine — 2,900 to 5,800 dollars (15-30 per sq ft)
- Cedar or redwood — 4,800 to 8,600 dollars (25-45 per sq ft)
- Composite (Trex, TimberTech, Fiberon) — 6,700 to 12,500 dollars (35-65 per sq ft)
- PVC and capped polymer — 8,600 to 14,400 dollars (45-75 per sq ft)
- Tropical hardwood (Ipe, Cumaru) — 9,600 to 17,300 dollars (50-90 per sq ft)
Larger decks scale in your favor on a per-square-foot basis because mobilization, design, and permit costs spread over more material.
What Drives the Cost Up
Five factors push the price beyond the baseline:
- Height off the ground — anything over 30 inches requires guardrails by code, and second-story decks need posts, beams, and more concrete.
- Stairs — typically 100 to 200 dollars per linear foot of stair run.
- Built-in features — benches, planters, pergolas, and fire pits add 800 to 5,000 dollars each.
- Lighting and electrical — post-cap LEDs and GFCI outlets run 600 to 2,500 dollars depending on circuit availability.
- Permit and engineering — most jurisdictions require a permit (150-700 dollars) and sometimes stamped drawings for raised decks.
Sloped or rocky lots can add another 1,000 to 4,000 dollars in framing and concrete.
Material Breakdown and Real Performance
Pressure-treated lumber is the budget leader but requires sealing every 2 to 3 years. Boards last 15 to 20 years with maintenance. Cedar and redwood smell better and resist rot naturally but soften over time and need annual care.
Composite decking has dominated the premium tier for a decade. Trex Transcend and TimberTech AZEK Vintage hold color for 25 to 30 years and need only soap-and-water cleaning. The sticker shock pays off if you plan to stay 10-plus years and value Saturday mornings without sandpaper. PVC takes this further with even better fade resistance and full waterproofing on the boards themselves.
Tropical hardwoods like Ipe deliver 40-plus years of life with minimal care, but they require pre-drilled fasteners (or hidden clips) and specialized framing techniques. Labor is roughly 25 percent higher than composite due to material density.
Labor vs Materials Split
On a typical pressure-treated build, labor runs about 50 to 60 percent of the total. On composite, the labor share drops to 35 to 45 percent because the material itself is more expensive. Hardwood pushes labor share higher again due to install difficulty.
Crews charge 35 to 65 per hour in most US markets, with skilled deck builders on the higher end. A 192 sq ft deck typically takes 4 to 7 days to frame, deck, and rail with a two-person crew.
Permits, Footings, and Framing
Almost every jurisdiction requires a permit for decks over 30 inches off grade or attached to the house. Footings must extend below the local frost line (12 inches in mild zones, 48 inches or more in northern climates). Skipping the permit can void homeowner insurance claims and triggers issues at resale.
Framing lumber should be ground-contact-rated 2×8 or 2×10 joists at 16-inch on-center spacing for composite (12-inch for diagonal patterns). Beams sit on concrete piers or helical piles. Ledger boards bolted to the house need flashing tape (Vycor or equivalent) to prevent water intrusion that rots the rim joist.
Common Add-Ons and Their Costs
- Aluminum railing — 70-110 per linear foot
- Cable railing — 100-160 per linear foot
- Tempered glass railing — 150-230 per linear foot
- Built-in bench seating — 80-160 per linear foot
- Pergola or shade structure — 3,500-12,000
- Hot tub framing reinforcement — 800-2,000
- Outdoor kitchen rough-in — 4,000-15,000
DIY vs Hiring a Pro
A DIY-capable homeowner can save 40 to 50 percent on labor by handling the build themselves. Plan on 80 to 120 hours for a 200 sq ft deck if you have framing experience. The risks are real: improperly attached ledger boards account for the majority of deck collapses recorded by the CPSC. If you have any doubt about ledger flashing, footing depth, or beam sizing, hire a pro.
For composite and PVC builds, the manufacturer warranty often requires authorized installers. Verify before you swing a hammer.
Final Cost-Saving Tips
Build in late fall or early winter when contractor schedules ease and prices soften. Stick to standard rectangular shapes; angles and curves can double the cut waste. Choose a single-color composite line rather than multi-tone variegated boards (the simpler products price 10-20 percent lower). Get three written quotes with identical scopes and material specs. The right answer to how much is a deck always comes down to matching the build to your lot, your climate, and your timeline. A modest pressure-treated platform done well beats an over-budget composite project that leaves you skipping the railing upgrades.
