What is the best decking material for Florida humidity?

Composite decking is the top choice for Florida. It resists moisture, humidity, mold, and UV fading far better than wood. If you prefer wood, use pressure-treated lumber rated for ground contact and plan to seal it annually.

Do I need a permit to build a deck in Florida?

Yes, Florida requires permits for most deck projects, particularly those attached to the home. Requirements vary by county. Miami-Dade, Broward, and Palm Beach counties have specific wind-load requirements due to hurricane risk.

October through April is ideal in Florida. Cooler temperatures and lower humidity make for better working conditions and faster drying of concrete footings. Avoid summer builds if possible due to afternoon thunderstorms and heat.
