Deck Builders Near Me in Miami, FL? Build Your Own Deck With an A-DIY Kit

Both are options. Miami-area deck contractors design and build custom decks, so compare two or three written quotes and confirm each contractor’s license, insurance and recent Miami-Dade projects. If you would rather build your own deck, A-DIY delivers professionally engineered wood and composite deck kits to Miami homes, and you or a local handyman can assemble one with just a drill.

Contractor prices in Miami vary with size, materials, height and permit requirements, and labor is one of the largest parts of the quote. Doing it yourself is usually cheaper: A-DIY deck kits range from $3,699 for a 6x12 wood kit to $12,799 for a 16x28 composite kit, and homeowners typically spend 30–50% less than hiring a contractor. Framing, decking, footings and hardware are included.

With A-DIY, a 12x12 deck kit is $4,899 in pressure-treated wood or $5,700 in composite. A 12x16 composite kit is $6,600; the closest wood size is 12x18 at $5,969. A 16x20 kit is $7,600 in wood or $10,199 in composite. Framing, decking, footings and hardware are included.

Usually, yes. Inside City of Miami limits, deck work goes through the City of Miami Building Department, and decks are not on the City’s list of work exempt from permit. In unincorporated Miami-Dade County, permits are handled by the County’s Department of Regulatory and Economic Resources. Hialeah, Coral Gables, Miami Beach, Doral and other cities run their own building departments, so confirm with the office that covers your address.

There isn’t one size limit. The Florida Building Code has no general deck exemption, and the City of Miami’s exempt-work list doesn’t include decks. Unincorporated Miami-Dade County exempts wood decks 18 inches or less above ground, but only while all exempt work on the property stays under $5,000 in a 12-month period. A-DIY kits assemble 15–17 inches off the ground, yet many sizes cost more than that cap, so check with your building department before you order.

Many customers use their A-DIY decks for hot tubs and saunas. Applicable configurations are engineered to hold up to 15,000 lbs when properly assembled and supported, but tub weight, placement and wiring vary, so talk to a deck specialist before you order and check local electrical and permit rules.

Miami has no frost line, so footing depth is about soil, drainage and wind uplift rather than freezing. The Florida Building Code’s residential provisions generally call for exterior footings at least 12 inches below grade, and the building official decides what a permitted deck needs. A-DIY kits are freestanding and include Tuff Block footings; whether that support is accepted for a permitted deck is up to the building official.

Hurricane season runs June 1 to November 30, and Miami-Dade is in Florida’s High-Velocity Hurricane Zone, where permitted structures face stricter wind-design and product-approval requirements, so ask your building department how a deck must be anchored. Summer rain, humidity, termites and salt air are the everyday challenges: keep the deck well drained, seal pressure-treated wood every one to two years, or choose composite decking for lower maintenance.

The dry season, roughly November through April, brings lower humidity, milder temperatures and fewer afternoon storms. Order in late summer or early fall so your kit and any permit are ready when the weather turns. Summer builds are possible, but plan around the heat and daily thunderstorms.

Pressure-treated wood kits come in 15 sizes: Standard 12x12, 12x18, 12x20, 12x24, 12x28, 16x16, 16x20, 16x24 and 16x28, plus Compact 6x12, 6x16, 6x20, 8x12, 8x16 and 8x20. Composite kits come in 9 sizes from 12x12 to 16x28 in Amazon Gray or Forest Wood. Custom sizes are available on request.
