Concrete footings in Key West FL - a base built for your flood zone and salt air
Planning a new home, an addition or raising your house? We plan footings around your flood zone, the load and the salt air.
Footing work means digging the trench, setting forms and steel, and pouring the concrete that carries what's built above. We lay it out square against your plans before the pour, because a footing out of line shows up in every wall above it.

What goes into concrete footings in Key West?
Concrete footings in Key West are the buried concrete and steel that carry a house, an addition, a wall or a raised floor, and we plan them from your flood zone, what they'll hold up and how close you are to salt water. The price moves with how much footing your plans call for, how deep we dig, the steel, the concrete mix and how easy the site is to reach. The schedule usually turns on your drawings and the paperwork more than the pour, so I ask early who's drawing the plans, and we handle the permit with the city when a footing job calls for one. Your estimate comes as a written scope with the price, so you can see what's included before anything is dug.
What signs say your footings need work?
Stair-step cracks in block walls
Cracks that climb a block wall like stairs usually mean part of the wall has dropped. We look at what's under it before anyone patches the crack.
A porch or post that's sunk
When a porch corner, carport post or stair has dropped away from the house, its footing is usually too small, too shallow or missing altogether.
Doors and windows that stick
Doors that suddenly drag or windows that won't close square can mean the house has settled unevenly. It isn't always the footings, so we check before suggesting work.
Posts on blocks or bare dirt
Older sheds, decks and carports often sit on loose blocks or posts set straight in the ground. Before you add weight or close them in, they need real footings underneath.

Questions about footings in Key West
Here are the questions we hear most about footings on the island. If yours isn't here, call (645) 300-7417 and ask.
How much do concrete footings cost in Key West?
An installed residential strip footing usually runs about $5 to $19 per linear foot across the US, covering the concrete, labor, digging and forms. Where yours lands depends on the things covered above, and your estimate comes with a written scope and the price.
Do I need a permit for structural work in Key West?
Yes. The city requires a building permit for any structural modification, whatever the cost, and the Building Department issues it. Any development in a flood hazard area needs a permit too, filling and grading included, and jobs valued at $5,000 or more need a recorded Notice of Commencement before the first inspection is scheduled.
What foundation does a home in a V Zone in Key West use?
Piles or columns. FEMA's flood rules don't allow fill as structural support for buildings in V Zones, the coastal zones that take waves, so homes there sit on pile or column foundations. In A Zones the building codes set how foundations are built, and we plan footings from your zone and what they'll carry.
How high does a new home have to be built in a Key West flood zone?
At least one foot above the base flood elevation, which is the flood height the maps set for your lot. The city requires that for new and substantially improved homes in its A and V flood zones, so footing plans for those jobs start from that height.
Does salt-resistant concrete cost much more for footings near the water?
Usually not much. FEMA's coastal builder's guide says a sound, durable mix where concrete meets salt water or salt spray usually costs nominally more and rarely adds significant cost. Salt is the main reason the steel inside concrete rusts early, so close to the water we ask for a mix made to stand up to it.
Do footings in the Key West Historic District need extra approval?
Exterior work in the Historic District needs a Certificate of Appropriateness as part of the building permit application. Whether a footing job on its own counts as exterior work depends on the project, so we plan for the historic review step before we set a pour date.
Is a Key West mailing address always inside the city?
Not always. Key Haven, Rockland Key and the south side of Stock Island can carry a Key West mailing address but sit outside the city, which sends them to Monroe County Floodplain Management. We check which office covers your address first, since that decides who handles the approvals.
Work that often goes with footings
- Service
Foundation raising
When a house sits too low or has settled, raising it often means new piers and footers underneath, so we plan the footings and the lift together.

Concrete cutting
Footings for an addition often run under an existing slab or walk, so we cut a clean opening rather than breaking out more concrete than the job needs.

Slab foundation building
If your new home or addition sits on a slab, we lay out the footings and slab together so the edges and steel line up.
