What’s different about New Jersey
New Jersey's dense permitting, high labor costs, and coastal salt exposure along the shore make exterior projects pricier than national norms.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
- Salt air favors corrosion-resistant materials and fasteners.
Expect quotes toward the higher end in New Jersey’s larger metros — Newark, Jersey City, and Paterson — where labor and permit costs run above the state average, and lower in rural areas.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
Resale value
A wood deck recoups about 50–83% of its cost at resale — more than a composite deck — according to the annual Remodeling Cost vs. Value report.
