Pressure-Treated Deck Cost Per Square Foot 2026
Homeowners typically pay a range of costs for a pressure-treated deck, with the largest drivers being deck size, labor, and material quality. The price experiences variation based on site accessibility, design complexity, and added features. This article breaks down the cost, with clear ranges and practical price guidance.

|---|---|---|---|---|
| Deck Size (sq ft) | 200 | 300 | 400 | Assumes standard rectangular shape |
| Material (PT Lumber & Fasteners) | $1.50/sq ft | $3.00/sq ft | $5.00/sq ft | Deck boards, supports, hardware |
| Labor & Installation | $4.00/sq ft | $6.00/sq ft | $10.00/sq ft | Crew, framing, railing attachment |
| Permits & Inspections | $0 | $100 | $750 | Depends on locality |
| Delivery & Cleanup | $50 | $150 | $300 | Depot to site, debris haul |
| Finishes & Accessories | $0 | $300 | $800 | Stain/sealant, fasteners |
| Taxes & Overhead | $0 | $200 | $600 | Regional variance |
Overview Of Costs
Cost ranges are expressed as per-square-foot estimates and total project values. The low-to-high spectrum reflects basic PT lumber with standard railing versus upgraded features and larger footprints. For a typical 200–400 sq ft deck, expect roughly $1,600–$8,000 in total costs, with per-square-foot pricing commonly cited as $8–$20. Assumptions: region, flat site, standard railing, and no specialized additions.
Assumptions: region, specs, labor hours.
Cost Breakdown
Breakdown shows where money goes in a typical PT deck project. The table below mixes totals and per-unit pricing to illustrate how pricing scales with size and scope.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $1.50/sq ft | $3.00/sq ft | $5.00/sq ft | Boards, joists, beams, hardware |
| Labor | $4.00/sq ft | $6.00/sq ft | $10.00/sq ft | Framing to finishing |
| Permits | $0 | $100 | $750 | Local requirements vary |
| Delivery/Disposal | $50 | $150 | $300 | Materials drop-off to site |
| Finishes | $0 | $300 | $800 | Stain/sealant, edge trim |
| Warranty & Overhead | $0 | $200 | $600 | Contractor overhead |
What Drives Price
Key price drivers include deck size, terrain, and design complexity. Larger areas require more materials and labor. Complex rail layouts, stairs, and angles add to both time and material costs. Availability of precise site access can affect crew efficiency and pricing. For example, stair runs longer than 8–10 feet or railings with decorative balusters may add to the cost per linear foot.
Assumptions: region, specs, labor hours.
Regional Price Differences
Prices vary by market with three broad U.S. regions showing distinct ranges. In the West, material costs can be higher due to logistics; the Midwest often presents mid-range pricing; the South may offer lower labor costs but similar material rates. Expected deltas: West +5% to +15%, Midwest ±0% to +5%, South -5% to -15% relative to national averages.
Assumptions: region, market conditions, season.
Labor, Hours & Rates
Labor is a major component of total cost, typically dominating in larger decks. Typical crew rates range from $45–$85 per hour depending on region and crew experience. For a 250–350 sq ft deck, labor often accounts for 60–75% of total cost due to framing, decking, railing, and finishing work. Install time commonly spans 2–4 days for mid-size projects, excluding permitting delays.
