FAQs — Deck Cost in New York
How much does a deck cost in New York?
A standard 16×20 ft deck (320 sqft) in New York, NY costs $10,900 for pressure-treated wood, $16,300 for cedar, and $23,300 for composite (Trex) — 55% above the national average of $8,500. Per-sqft rates: PT wood $34/sqft, composite $73/sqft. Costs include framing, decking boards, stairs, and basic railings.
Is composite or wood decking better in New York?
In New York's humid climate, composite decking (Trex, Fiberon) is strongly recommended. It won't rot, warp, or grow mildew — major problems for wood in humidity. While composite costs $12,400 more upfront, it requires no annual sealing/staining and lasts 25–30 years with minimal maintenance.
Do I need a permit to build a deck in New York?
Yes — most deck projects in New York require a building permit if the deck is attached to the house, over 30 inches off the ground, or over 200 sqft. Permits cost $225–$625 in New York and require structural drawings and a post-installation inspection. A licensed NY contractor will handle permits as part of the project. Unpermitted decks must be disclosed at sale and may need to be removed or permitted retroactively.
How much does a 12×12 deck cost in New York?
A 12×12 ft deck (144 sqft) in New York, NY costs: PT wood $6000–$7100, cedar $9000–$10600, composite $12800–$15100. Smaller decks have higher per-sqft costs since fixed costs (footings, framing, stairs) spread over fewer square feet. A 12×12 is popular for smaller yards and costs approximately 55–65% of a 16×20.
What is the ROI on a deck in New York?
A wood deck in New York recoups approximately 65–75% of cost at resale according to Remodeling Magazine's Cost vs. Value report. A $10,900 PT wood deck adds $7600–$8200 to your home's value. Composite decks often recoup a similar dollar amount to wood but at a higher cost, so the percentage ROI is lower. In New York's market, outdoor living spaces are increasingly valued — a well-built deck is one of the top outdoor ROI projects.
