Do I need a permit to build a deck in the Atlanta area?

Almost always for an attached deck or one more than about 30 inches off the ground. Requirements differ by county and city, so call your building department. A contractor should pull the permit and schedule the inspections.

Wood costs less to build and needs sealing or staining every one to three years. Composite costs more, needs little upkeep, and can get hot in direct Georgia sun. Pick based on how long you will keep the house and how much upkeep you will tolerate.

How long does it take to build a deck?

A standard deck takes one to three weeks of build time, after permit approval and material lead time. Permit review can take longer than the build itself.

How long will a deck last?

Pressure-treated pine typically lasts 10 to 20 years with upkeep. Composite often carries 25-year manufacturer warranties, though the framing underneath is usually still wood.

Can I put a new deck over my old one?

Sometimes you can re-deck over sound framing. Old framing is often rotted at the ledger and posts, and putting new boards on it hides problems. A contractor should probe the frame before agreeing to it.

Deck Building Cost in Atlanta (2026)

Reviewed 2026-10-08 · metro Atlanta

A new deck in metro Atlanta costs about $16 to $50 per square foot installed, which puts a typical 300 sq ft deck between $6,000 and $55,000 depending on material, height, and extras. Pressure-treated pine is the low end, and composite with railings and a roof is the high end. These are typical metro Atlanta market ranges, not a quote from WS Painting & Remodeling. Your price depends on your house, your selections, and what is behind the walls.

What it typically costs

budget

$6,000–$10,000

Ground-level or low 300 sq ft deck in pressure-treated southern pine. Basic railing, one set of stairs, standard footings.

mid

$12,000–$22,000

300 to 400 sq ft deck, either upgraded pressure-treated or entry-level composite decking. Code-compliant railing, wider stairs, built-in bench or planter, and lighting.

high

$28,000–$55,000

Elevated or multi-level deck with premium composite or tropical hardwood, aluminum or cable railing, and a covered or screened section with electrical.

Ranges were set from a 2026 review of Atlanta-area pages (Angi, ContractorPlus, Homeyou, Constructly). Per-square-foot figures run from about $16 to $50, with pressure-treated pine around $16 to $18 installed and published labor-only rates of $14 to $32. Totals above assume roughly 300 to 400 sq ft. Verify against current quotes.

What moves the number

Decking material. Pressure-treated pine is often $16 to $18 per sq ft installed. Composite typically starts around $30 and goes up from there.
Height off the ground. Decks over about 30 inches need guardrails, and tall decks need larger posts, beams, and more footings.
Red clay. Atlanta soil holds water and moves. Footings must reach below the frost line and bear on firm soil, and wet or sloped lots can add excavation and drainage work.
Railing. Railing can be 15 to 25 percent of a deck cost. Aluminum and cable run far more than wood.
Attachment to the house. A deck attached through a ledger board needs proper flashing, and this is the most common source of deck failure.
Permits and inspections. Most counties in the metro area require a permit and footing inspection for a new deck. Fees and review time differ by jurisdiction.
Add-ons. Roofs, screens, outdoor kitchens, and built-in lighting each change the number substantially.

How to spend less

Choose pressure-treated pine over composite. It costs about half as much up front. If you do not mind staining it every couple of years, it can last 15 years or more.
Build lower and smaller. Every extra foot of height and every added square foot compounds the cost.
Use wood railing instead of aluminum or cable.
Skip the deck contractor for a ground-level platform and build it yourself if you are handy and the deck is not attached to the house. We would lose the job, but a 12 by 12 ground-level deck is a reasonable DIY project.
Do not skimp on footings, flashing, or hardware. These are the parts you cannot fix cheaply later.
Add lighting, benches, and planters in a second phase. The deck is usable without them.
Compare lifetime cost. Composite costs more now but needs less upkeep, and in a house you keep for 15 years the gap narrows.
