Jacksonville’s outdoor lifestyle makes custom decks one of the most popular home improvement projects in Duval County. Whether you are building a ground-level composite deck for backyard entertaining or an elevated hardwood deck at the Beaches, here is what custom deck construction costs in Jacksonville in 2026.
Jacksonville Deck Cost by Material
| Deck Type | Cost per Sq Ft (Installed) | 300 Sq Ft Deck | 500 Sq Ft Deck |
|---|---|---|---|
| Pressure-treated pine | $15–$25 | $4,500–$7,500 | $7,500–$12,500 |

These prices include materials, labor, footings, framing, and decking installation. Railings, stairs, lighting, and built-in features add to the total.
Additional Cost Factors

Jacksonville-Specific Considerations
Wind Engineering
Duval County requires deck structures engineered for 140+ mph wind speeds. This affects footing depth, joist spacing, and ledger board connections. Engineering plans typically cost $600-$1,200.
Coastal Corrosion (Beaches Communities)
For decks in Jacksonville Beach, Neptune Beach, and Atlantic Beach, all fasteners and connectors must be stainless steel or hot-dip galvanized. Standard zinc-plated hardware corrodes within 2-3 years. Budget an additional 10-15% for coastal-grade hardware.
Permitting
Duval County requires building permits for decks over 30 inches above grade or attached to the house. Permit review currently takes 3-5 weeks. Wilson & Co handles all permitting.
Soil Conditions
Jacksonville’s sandy soil requires footings at adequate depth for stability. We typically pour footings 18-24 inches deep with concrete footings a minimum of 12 inches in diameter.
