What makes a deck in Miami cost what it does
Salt air, sun, humidity and hurricane winds; termites are constant.
Labour here runs 10% above the Florida average, so a pressure-treated 12×16 that averages $3,923 across Florida comes to about $4,194 in Miami. Sun, humidity, subterranean and Formosan termites, and hurricanes. Frost is not a factor; wind uplift and rot are.
Footings
Footings in Miami go about 12 inches deep, which costs roughly $128 per 12 inch footing installed. A 12×16 deck needs about 3. Size them with the deck footing calculator.
Deck permits in Miami
Permits are issued by the Miami-Dade County / City of Miami Building Department. Miami-Dade is in the High-Velocity Hurricane Zone, so connections and some products need approval and permits require drawings. Typical fees run $300–$1,000. For the state rules that sit behind the local ones, see deck cost in Florida.
