💬What People Actually Paid
Community❓Common Questions
Yes. Unlike many other jurisdictions, NYC requires a formal Alteration Type 2 (Alt-2) filing for virtually all deck construction. This process must be handled by a licensed Professional Engineer (PE) or Registered Architect (RA), which typically adds $1,500 to $3,000 in professional fees alone.
As of 2026, the minimum filing fee is $130 for the first $5,000 of project value. For projects exceeding this, the fee increases by approximately $13 for every additional $1,000 in construction costs. A typical $15,000 deck project would incur roughly $260 in basic DOB filing fees.
In the NYC market, pressure-treated wood decks average $30–$45 per square foot installed. Composite decks (like Trex) are significantly higher at $55–$85 per square foot due to material premiums and the specialized labor required for hidden fastening systems.
NYC costs are 40-50% higher due to union labor rates (averaging $80-$120/hour), complex logistics like crane operation approvals for rooftop decks, and strict adherence to the 2022 NYC Building Code and Local Law 97 requirements.
