Deck Builders in Florida: FL Deck Costs, Permits and a Faster Way to Build

Florida homeowners can hire a state-licensed deck contractor, build from raw lumber themselves, or assemble an A-DIY engineered deck kit. A-DIY ships the complete deck system to your door, and you, a friend or a local handyman can put it together in a few hours with just a drill.

Contractor pricing in Florida depends on where you live, the deck’s size, material and height, local labor rates and the wind and engineering requirements of your county. A-DIY deck kits start at $3,699 for pressure-treated wood and $5,700 for composite, typically 30–50% less than hiring a contractor. Use our deck cost calculator to compare prices in your area.

Yes. An engineered deck kit delivers a genuine structural deck without the design time and full labor bill that come with a contractor. Every A-DIY kit arrives complete, footings included, so there is no cutting, measuring or hunting down materials in the summer heat.

No. A-DIY does not install decks and is not a Florida-licensed contractor. We design, engineer and deliver complete deck kits anywhere in Florida, and you can assemble the kit yourself or hire any local handyman, carpenter or contractor to do it for you.

Yes. Many Florida homeowners bring in a local handyman to assemble their A-DIY kit, and because the parts arrive ready to assemble with step-by-step instructions, the job takes far less time than a custom build. Florida regulates contracting at the state level, so if your deck needs a permit, ask your building department who may perform the work or pull an owner-builder permit and supervise the assembly yourself.

Usually, yes. The Florida Building Code applies throughout the state, and your county or city building department enforces it. Some jurisdictions exempt low, detached decks, with Miami-Dade County, for example, exempting wood decks 18 inches or less above the ground, but attached or elevated decks almost always need a permit. Check with your local building department before you build.

Jacksonville’s Building Inspection Division enforces the Florida Building Code 8th Edition (2023) throughout Duval County. Permit applications go through the city’s online JaxEPICS portal, and a homeowner pulling their own permit signs an owner’s affidavit. Contact the division before you order or build to confirm what your deck requires.

Florida has no frost line, so there is no frost-depth requirement. The Florida Building Code, Residential calls for exterior footings to sit at least 12 inches below finished grade on undisturbed soil, and your building department may add requirements for sandy soils, high water tables or flood zones. Always confirm locally before you dig.

Yes. An A-DIY deck can be installed over sloped or uneven ground by adjusting the supporting post heights to create a level deck surface. Supported configurations can be elevated to approximately 40 inches using the appropriate posts, foundations and bracing.

Every A-DIY kit includes Tuff Block footings, which keep the posts out of direct contact with the soil. Depending on your property, deck height and local requirements, other foundation systems may be used instead, such as sonotubes, helical piles, ground screws, in-ground posts or approved surface footing systems.

Both can last in Florida. Pressure-treated wood costs less upfront and resists termites and decay, but Florida’s sun, humidity and daily summer rain mean it needs regular sealing or staining to stay in good shape. Composite costs more but needs no sanding, staining or sealing, shrugs off UV fading and splintering, and its boards carry a 25-year warranty.

Applicable A-DIY deck configurations are engineered to hold up to 15,000 pounds when properly assembled, supported and installed according to the applicable specifications. Every A-DIY deck system also includes a five-year structural warranty.

A-DIY delivers to cities and towns from the Panhandle to the Keys, typically within 10–14 business days. Your deck arrives with all components and hardware included, so you can start building as soon as it reaches your driveway.

Yes. You can choose Build Now, Pay Later financing through Affirm (subject to approval), 0% split payments over up to eight months, or A-DIY Reserve, a $250 deposit that locks in today’s price for a future delivery date.

Yes. Diagrams for an applicable A-DIY configuration show dimensions, structural layout, beam, joist and post locations, lumber sizes and major connections, which can support your permit application. Florida building departments may still ask for a site plan, survey, wind-load information or signed and sealed documents, and approval is not guaranteed.
