How much does it cost to build a deck in New York, NY?
A new deck in New York, NY typically costs $30–$65 per square foot installed — a 16×20 pressure-treated deck runs roughly $10,000–$18,000, and composite decking pushes the same deck to $16,000–$28,000. Honest quotes include permits, footings, stairs, and railings; they're the most common 'extras' in cheap ones. Height matters: a raised deck costs meaningfully more than a ground-level one.
What you can check yourself
- Decide material first: pressure-treated lumber is cheapest; composite costs ~60% more upfront but skips sealing and most maintenance.
- Ask whether the quote includes the permit and inspections — most towns require both for raised decks, some for all decks.
- Get the footing depth and ledger-attachment method named in writing; ledger failure is how decks collapse.
Typical cost
Typical in New York, NY: $30–$45/sq ft pressure-treated; $50–$65/sq ft composite. Stairs, benches, and lighting add $500–$3,000.
When to call a pro
Decks attach to the house and carry crowds — permit-and-inspection work for a licensed contractor, not a weekend crew. An existing deck with a pulling-away ledger board or rotted posts shouldn't host a party until it's inspected.
