What changes the price in Florida
Florida's climate: hot and humid year-round, with a June–November hurricane season. These local factors matter most for deck projects:
- No frost footings, but wind matters. Florida decks need metal hurricane ties and connectors at posts, beams and joists to resist uplift.
- Termites and rot. Termite risk here is very high (the highest risk in the continental US, including Formosan termites). Use ground-contact treated lumber for posts and framing near the soil.
- Humidity means more maintenance. Wood decks here need cleaning and sealing more often; composite or PVC costs more up front but saves years of upkeep.
- Most attached decks need a permit. Under the IRC, only small, low, freestanding decks (under 200 sq ft, under 30 in high and not serving an exit door) skip it.
Labor, sales tax and permits in Florida
- Labor and prices: Florida's construction cost index is 0.95 — 5% below the US average, the 31st highest of the 50 states and DC. Prices in big metros (Miami, Tampa, Orlando) usually run above the state average, and rural areas below it.
- Sales tax: 6% state rate plus a county surtax in most counties (usually 0.5–1.5%). The estimates on this page don't include it.
- Building rules: Florida follows the Florida Building Code, which applies statewide and includes strict wind-load rules. Permits and inspections are handled by your city or county, so confirm requirements with your local building department before you start.
