Building a Deck in Florida — What to Know
1. Florida Costs vs. National Average
Deck building in Florida is above the national average (cost index: 1.85×). A 300 sqft composite deck averages $19,425 — composite costs 75% more than pressure-treated but requires virtually no maintenance.
2. Best Deck Material for Florida
Florida decks face high humidity, UV exposure, and hurricane wind load requirements. Composite decking significantly outperforms wood in Florida's climate — wood decks require annual sealing and often last only 10–15 years. Hurricane-rated fasteners and footings add cost but are code-required in coastal counties.
3. Permits & Requirements in Florida
Most decks over 30 inches above grade require a building permit in Florida. Permit costs average $200–$600. Attached decks require structural assessment of the ledger board connection to your home. Always pull permits — unpermitted decks must be disclosed at sale and can require removal.

Florida's climate and precipitation levels affect how quickly wood degrades — composite is a better investment in states with significant rain or temperature swings.
