New deck cost in Florida is driven by size, material, and height — an attached or elevated deck is licensed structural work, and the material choice matters a lot in the state's sun and moisture.
Plan it — not an emergency.
Common causes:
• Deck square footage and height off the ground
• Material — pressure-treated wood, composite, or hardwood
• Structural attachment to the house and footings
• Railings, stairs, and any permits
• An unlicensed builder on an attached or elevated deck
• Skipping the permit and inspection on structural work
• Under-built footings or ledger in Florida conditions
• An unlicensed contractor for structural deck, dock, or seawall work — Florida licenses this; no license means no permit rights, no inspection, and no recourse
What drives the cost of a new deck?
Size and material first, then height and structural complexity. Composite costs more upfront than pressure-treated wood but holds up better in Florida's sun and moisture with less upkeep. An elevated or attached deck needs proper footings and a code-compliant ledger connection — licensed structural work, and where a permit and inspection matter.
Do I need a permit and a licensed contractor for a deck?
For an attached or elevated deck, almost always — it's structural, and Florida requires it be built to code with a permit and inspection, by a licensed contractor. A small ground-level platform may be lighter scope. Permitting protects you: an unpermitted deck can cause insurance and resale problems and may be unsafe.
New deck construction: $4,500–$18,000 (typical ~$9,000)
By square foot and material; an attached or elevated deck is licensed structural work.

Florida licenses this trade at the STATE level (DBPR / CILB (marine + structural/deck scope)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
Basis: FL Stat. 489 (DBPR state licensing).
