Most of what ruins a deck here isn't bad carpentry. It's something nobody checked before the first post went in. Fort Lauderdale has its own list of problems that a deck builder in, say, Atlanta or Denver never has to think about: canal lots, flood elevation, salt air eating hardware from the inside, and a water table that sits closer to the surface than most homeowners realize. Here are ten things worth running down before you sign a contract or pour a footing.
1. Where your property line and the canal actually are
A huge number of lots in this city back up to a canal, a lake, or the Intracoastal. If your deck is going anywhere near that edge, you need to know the setback from the seawall, not just the property line. Seawalls move, settle, and sometimes aren't exactly where the old survey says they are. Pull your survey before you start sketching a layout. If you don't have one, your builder can usually order one, and it's worth the cost compared to building six inches into a setback you didn't know existed.
2. Your flood zone and base flood elevation
A lot of Fort Lauderdale, especially near the New River, the canals in Rio Vista and Harbor Beach, and low-lying pockets inland, sits in a FEMA flood zone with a published base flood elevation. That number can affect how high your ledger board sits, how your posts are footed, and whether an elevated deck needs engineering review at all. Nobody wants to find this out after the framing is up.
3. What's actually under the sand
South Florida soil is mostly sand over oolitic limestone, and the water table can sit just a few feet down, closer after a wet summer. Sand drains fast, which is good, but it doesn't hold a post the way clay or loam does. Footings here typically go 12 to 24 inches down depending on the span and the engineer's call, sometimes hitting rock sooner than you'd think. If a crew is hand-digging footings and hits limestone at 14 inches, that changes the plan on the spot. Ask how footing depth gets decided for your specific lot, not a generic number.
4. Whether your HOA has a say
Plantation, Weston, and a lot of the newer gated communities west of I-95 have active HOAs with design review for anything visible from the street or the golf course, including railing style and stain color. Older neighborhoods like Victoria Park, Poinsettia Heights, and most of unincorporated Broward don't have that layer. Check your HOA documents before you fall in love with a railing design. Getting told to redo it after installation costs real money.
5. What permit and inspection this actually needs
The City of Fort Lauderdale, or Broward County if you're outside city limits, requires a permit for most new deck construction and for structural repairs, including replacing ledger boards, posts, or beams. Staining an existing deck or swapping a few boards usually doesn't trigger one. A permitted job gets a framing inspection before boards go down and a final inspection after railings are up. Anything over a certain height off grade, usually around 30 inches, needs guardrails that meet code spacing, and most jurisdictions here want baluster gaps no wider than 4 inches so a small child can't pass through.
6. Whether the ledger board attachment is done right
The ledger is the board bolted to your house that the whole deck hangs off of, and it's the single most common failure point in deck collapses nationwide. In this climate it has two enemies: water getting trapped behind it and corroding the lag bolts, and wind uplift during storm season. It needs proper flashing behind it so rain doesn't sit against your house's sheathing, and it needs through-bolts or structural screws rated for the load, not just construction-grade lag screws. If a crew is nailing a ledger on with a few nails and calling it done, that's a problem.
7. What kind of hardware is actually going into the frame
Salt air off the ocean and the Intracoastal is hard on metal, even miles inland on a humid day. Standard galvanized screws and joist hangers will rust through faster here than in a dry climate, sometimes within a few years on a coastal lot. Stainless steel fasteners, or at minimum hot-dip galvanized hardware rated for coastal exposure, cost more up front and save you a framing repair later. Ask specifically what hardware is spec'd, not just what wood or composite is going on top.
8. How the wood or composite will handle the heat and the rain
Pressure-treated pine is still the budget choice, and it checks and cups faster here than up north because of the swing between a wet morning and a 95-degree afternoon in July or August. It needs to fully dry out, usually a few weeks after install, before it gets stained or sealed, or the sealer just traps moisture under the surface. Composite decking doesn't rot, but dark composite boards can get hot enough on a July afternoon that bare feet won't thank you, and the color fades faster under south Florida sun than the sample board in the showroom suggests. Neither material is wrong, but both behave differently here than the manufacturer's national marketing implies.
9. Where the water goes once it hits the deck
Fort Lauderdale gets heavy, fast rain from June through October, often an inch in twenty minutes during a summer storm. A deck with no slope, or boards laid tight with no gap, holds water instead of shedding it, and standing water under a low deck is a mosquito problem as much as a rot problem. Boards should have a slight pitch away from the house and a gap of about an eighth to a quarter inch between them. If the ground under the deck doesn't drain, that's worth fixing before the deck goes on top of it, not after.
10. The condition of what's already there, if you're resurfacing
If you're replacing boards on an existing deck instead of building new, get under it and look at the joists before you pick a new decking material. A deck built in the 1980s or 90s in an older neighborhood like Rio Vista or Riverside Park may have framing that's done its job for thirty-plus years and is now soft at the joist ends where water's been wicking in. New boards on top of rotten framing just hide the problem for another season. A builder worth hiring will check this before quoting the resurfacing job, not after they've pulled the old boards up.
None of this is complicated, but it's easy to skip when you're excited to get a deck built and someone's given you a fast quote. If you want someone to walk the lot with you and point out which of these actually apply to your property, that's the kind of site visit Oasis Deck Company does before any contract gets signed.
