A new deck is one of the highest-ROI home improvements you can make in Atlanta—but pricing varies widely depending on materials, size, height, and complexity. This 2026 guide breaks down exactly what you can expect to pay so you can budget with confidence.

Average Deck Cost in Atlanta
For most Metro Atlanta homeowners, a new deck costs between $6,000 and $24,000, with the average project landing around $12,000-16,000. The single biggest factor is the decking material you choose, followed by size, height off the ground, and design complexity.
Here's the simplest way to think about it: multiply your planned square footage by the installed cost-per-square-foot for your material. A 400-square-foot composite deck at $35/sq ft, for example, runs about $14,000.
Deck Cost by Material (2026)
Installed Cost Per Square Foot
- Pressure-treated pine: $15-25/sq ft
- Cedar: $20-30/sq ft
- Composite (Trex, TimberTech): $30-45/sq ft
- PVC / capped polymer: $35-50/sq ft
- Exotic hardwood (Ipe, Cumaru): $40-60/sq ft
Pressure-Treated Pine
The most budget-friendly option and still the most common in Atlanta. A pressure-treated deck costs less upfront but requires regular staining and sealing to survive Georgia's humidity and sun. Expect to refinish every 2-3 years.
Composite Decking
Composite (a blend of wood fibers and plastic) has become the most popular choice for Atlanta homeowners who want low maintenance. It costs roughly double pressure-treated upfront but never needs staining and resists Atlanta's mold and mildew. Most brands carry 25-50 year warranties.
Exotic Hardwoods
Ipe and other tropical hardwoods are stunning and incredibly durable, but they're the priciest option and require specialized installation and periodic oiling to maintain their color.
Cost by Deck Size
Estimated Total Cost (Composite, Installed)
- 200 sq ft (10x20): $6,000-9,000
- 300 sq ft (12x25): $9,000-13,500
- 400 sq ft (16x25): $12,000-18,000
- 600 sq ft (20x30): $18,000-27,000
What Drives Deck Costs Up
Height and Stairs
Many Atlanta homes are built on sloped lots, requiring elevated decks with tall support posts and long stair runs. A deck 10+ feet off the ground costs significantly more than a ground-level platform due to additional framing, footings, and code-required railings.
Railings
Railing choice has a big impact. Pressure-treated wood railing is cheapest ($20-30/linear ft), while aluminum, composite, and cable railing systems run $60-120/linear ft installed.
Permits and Inspections
Most Metro Atlanta counties (Fulton, Cobb, Gwinnett, DeKalb) require permits for decks attached to a home or above a certain height. Permit costs typically range from $150-500. A reputable builder includes permitting in their quote.
Add-On Features
- Built-in benches: $40-80/linear ft
- Deck lighting: $1,000-3,000
- Pergola: $4,000-12,000
- Under-deck drainage: $1,600-4,800
- Multi-level design: +15-25% over single level
Labor vs. Materials
For a typical Atlanta deck, expect roughly a 50/50 split between materials and labor. Complex designs, elevated builds, and premium materials shift more of the budget toward labor because of the additional skill and time required.
Is a Deck Worth the Investment?
Decks consistently return 60-80% of their cost at resale, and in Atlanta's outdoor-living-focused market, a quality deck is a major selling point. Beyond resale value, a well-built deck adds usable living space you'll enjoy for years.
