Deck Building in Georgia

Pressure-treated, composite, or hardwood — what each actually costs, how long they last in Georgia humidity, and the permit you can't skip.

Pressure-treated deck
$25 – $40 / sqft
Typical 300 sqft = $7,500–$12,000
Composite (Trex, TimberTech)

Typical 300 sqft = $13,500–$21,000
Hardwood (ipe, mahogany)
$60 – $100 / sqft

How long it takes

Small decks (200–300 sqft) take 1 week. Mid-size with railings and stairs run 2–3 weeks. Multi-level or covered decks: 4–6 weeks plus permit time.

Permits & inspections

Georgia requires a building permit for any deck over 30 inches off the ground or attached to the house. Inspections check footing depth, ledger board attachment, and railing height. Skip the permit and you'll have insurance problems if anyone gets hurt.

Mistakes that cost the most

  • Lag-bolting the ledger into siding instead of the rim joist (collapse risk)
  • Using regular screws instead of structural connectors and joist hangers
  • Setting footings shallower than 12" (frost heave in north Georgia)
  • Building over an unprotected gas/water line
  • Skipping the permit to save 2 weeks (kills resale, voids insurance)

Contractor tips

  1. 1Verify GL insurance for at least $1M
  2. 2Confirm the ledger board attachment method in writing
  3. 3Ask for a detailed material list (board count, fastener type, joist spacing)
  4. 4Get a 1-year workmanship warranty in writing
  5. 5Verify the deck builder pulls the permit, not you

Financing

HELOC or cash. Most deck companies' 0% financing adds 10–15% to the price; ask for a cash discount.

Frequently asked

Composite or pressure-treated?

If you'll keep the home 8+ years, composite pays back through zero maintenance. Under that, pressure-treated wins on upfront cost.

How long does pressure-treated last in Georgia?

10–15 years with annual sealing. Without sealing: 7–10 years before cupping and splitting.

Do I need a permit for a ground-level deck?

If it's under 30" off grade and detached from the house, usually no. Anything else: yes.
