What Does a New Deck Cost in Atlanta, GA in 2026?

The honest answer to "what does a deck cost" is always "it depends," but the variables that actually move the number are pretty consistent from project to project. Here's what drives an Atlanta deck estimate up or down.

Material Is the Biggest Line Item

Pressure-treated wood decks run $35 to $52 per square foot installed — about $14,000 to $21,000 for a 400 square foot deck. Composite decking runs $60 to $115 per square foot depending on tier, or roughly $24,000 to $46,000 for that same footprint. Cedar and hardwood species like ipe or cumaru land between the two, with a higher upfront cost but less long-term maintenance than pressure-treated pine.

Size and Elevation

Square footage scales cost in an obvious way, but elevation matters almost as much. A deck more than a step or two off the ground needs deeper footings, additional bracing, and usually a stair run, which adds labor even before you touch decking material. Multi-level designs on sloped lots — common across Fulton, Cobb, and Cherokee counties — cost more per square foot than a simple ground-level deck for the same reason.

Permits Aren't a Hidden Fee Here

Building permits are required for most deck projects across Metro Atlanta. We manage the entire permit process — drawings, filing, inspections — at no additional charge, so it shouldn't show up as a surprise line item on a real estimate.

Add-Ons That Move the Total

Pergola additions start around $8,000 for simple designs and run $20,000 or more for custom structures. Pool deck surrounds generally run $10,000 to $40,000 depending on size and drainage needs. Both are usually quoted separately from the base deck so you can see exactly what each piece costs.
