Homeowners typically pay a wide range for a backyard deck, with costs driven by size, materials, and labor. This guide details the cost to build a deck, including per-square-foot rates and setup considerations for common scenarios. Expect the overall price to reflect material type, labor hours, and local permit requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Deck installed, 200 sq ft, pressure-treated lumber | $6,000 | $9,000 | $12,000 | Includes framing, decking, basic railing |
| Deck installed, 200 sq ft, pressure-treated + basic stain | $7,000 | $10,500 | $14,000 | Protective finish included |
| Composite decking, 200 sq ft | $12,000 | $18,000 | $26,000 | Mid-range to premium composites |
| Labor only, 200 sq ft, standard crew | $4,000 | $6,500 | $9,000 | Excludes materials |
| Permits and inspections | $200 | $1,200 | $3,000 | Varies by county |
| Railing upgrade, composite or aluminum | $2,000 | $4,500 | $8,000 | Code-compliant railing |
Introduction A backyard deck cost hinges on deck size, chosen materials, and labor rates. Typical projects span pressure-treated wood, cedar, composites, or PVC, with price impacts from permit fees, soil conditions, and site access. The figures below reflect common U.S. pricing patterns and assume standard access and normal climate zones.
Cost Breakdown by Material Type and Size
Material choice drives the largest portion of the price. Pressure-treated wood remains the most affordable option, while composite decking and PVC decking cost more upfront but often reduce maintenance. Typical ranges for 200 sq ft decks illustrate scale effects: larger decks pay less per square foot on some components, while premium materials maintain higher per-square-foot costs.
| Material | Low per sq ft | Average per sq ft | High per sq ft | Notes |
|---|---|---|---|---|
| Pressure-treated lumber | $6 | $9 | $12 | Framing and decking with basic fasteners |
| Cedar | $8 | $13 | $18 | Natural look, higher maintenance than PT |
| Composite decking | $8 | $14 | $22 | Includes boards and hidden fasteners |
| PVC decking | $12 | $20 | $28 | Lowest maintenance, highest up-front |
Assumptions: Midwest to South regions, standard 4×4 posts, ground-level site, normal access, and basic railing.
Labor Costs: How Much for the Build Crew
Labor is typically quoted as a total project price or per-square-foot rate. In many markets, a mid-sized crew completes a 200 sq ft deck in about 2-4 days. The range below assumes 1-2 carpenters plus a supervisor and basic site prep. Labor can represent roughly 40-60% of the total project cost depending on material and complexity.
| Scenario | Low | Average | High | Notes |
|---|---|---|---|---|
| 200 sq ft with PT lumber | $4,000 | $6,000 | $9,000 | Includes framing, decking, railing prep |
| 200 sq ft with composites | $6,000 | $9,000 | $14,000 | Labor-intensive fasteners and fittings |
Assumptions: Standard two-person crew, 8- to 10-hour days, regional wage variance included.
Permits, Inspections, and Code Requirements
Permits vary by county and deck size. A small, ground-level deck may need no permit in some areas, while larger elevated decks typically require plan review and inspections. Typical costs include plan review fees, permit issuance, and site inspections. Expect $200-$3,000 in permit costs depending on locality and deck height.
Regional Price Variations Across the United States
Prices shift with regional labor rates and material access. The Pacific Coast and Northeast markets generally show higher ranges, while the Midwest and South tend to run lower figures for similar scope. Use region-specific quotes to anchor budgeting.
Project Scope Extremes: Small vs. Large Decks
Smaller, ground-level decks (<100 sq ft) trend toward lower per-square-foot pricing, while large elevated designs (>300 sq ft) spread fixed costs across more area. For example, a 120 sq ft PT deck may cluster around $4,500-$7,000, whereas a 400 sq ft composite deck can exceed $18,000-$28,000 depending on railing and stairs. Size drives per-square-foot cost and total labor hours.
Railings, Stairs, and Lighting: Add-Ons that Change the Total
Rails and stairs add significant value but raise price. Material choice for railing (wood vs. aluminum vs. cable) and the number of stairs determine both material and labor costs. Lighting, steps, and bench seating can add $1,000-$3,000 in mid-range setups.
Maintenance and Long-Term Costs to Consider
Decks incur ongoing costs for staining, sealing, and eventual replacement. Stain or seal every 2-3 years for wood decks, while composite decks require less maintenance but may need periodic cleaning. Budget for ongoing upkeep when evaluating initial price.
Practical Ways to Reduce Backyard Deck Costs
Control scope to avoid overbuilding. Compare premium vs. standard materials, plan for efficient framing, and time installations to avoid peak rates. Bundling tasks like removal of an old deck with installation can reduce total charges and help meet budget constraints.
Concrete Price Example: Per-Unit and Per-Sq-Ft Details
When a concrete base or footings are needed, pricing can add $300-$900 per footing depending on depth and access. For a typical deck, factor several footings at the per-foot cost. Footing costs vary with frost depth and soil type.
Quote Comparison: What to Ask Contractors
Request itemized quotes that separate materials, labor, permits, and disposal. A realistic quote will include a clear breakdown and a per-square-foot rate for each material option. A side-by-side comparison helps prevent sticker shock.
| Component | Low | Average | High | Notes |

| Materials (PT lumber) | $4,500 | $7,500 | $10,500 | Includes boards and fasteners |
| Materials (Composite) | $9,000 | $14,000 | $22,000 | Higher upfront, lower maintenance |
| Labor | $4,000 | $6,500 | $9,000 | Crew wages and duration |
