Foundation raising in Key West FL - a house set at the height your flood rules require

Your house sits lower than your flood rules ask. We help plan the raise and pour the footings and piers it stands on.

Raising a house means lifting it off its old supports and setting it on new concrete ones, higher than before. We start with your address and your house, then plan the footings and piers it will stand on.

What does raising a house in Key West involve?

Foundation raising in Key West means a crew gets beams under your house, lifts it to the height your community's flood rules require and sets it on new supports. That height comes from the flood rules, not from your contractor, and it's the main cost you can't negotiate, so I look it up with you before anything else. From there, the price moves with your foundation type and how much of the old foundation can stay, and the schedule turns on permits, any historic review and when you can be out of the house. My written scope gives you the price for your house.

Foundation raising in Key West by house type

  • Pier and beam or crawl space

    These are usually the cheapest houses to raise, because the crew can reach the space under the floor with less digging. Many older island houses already sit up this way, so our part is mostly new footings and piers under the same frame.

  • Houses built on a slab

    A slab house is harder to raise, because the slab has to be separated from the house or lifted with it, and that adds engineering and labor. When the slab is separated, concrete cutting is often part of the work.

  • Open foundation on piers and footers

    Setting the house on piers over concrete footers, the wide pads the piers stand on, leaves the space underneath open so floodwater passes under the house instead of pushing against its walls. Monroe County has proposed this kind of foundation for some single-family homes in Key West.

  • Replacing the whole foundation

    When the old piers or footings can't carry the house again, the foundation gets replaced as part of the raise. I look under your house at the first visit, so you know which kind of job you have before the price goes in writing.

  • New steps and a driveway to match

    A house set higher needs new steps up to the door, and the driveway may have to climb to meet it. We can rebuild the concrete driveway on a dug-out, packed base that sends water away from the house.

How do you know your house needs raising?

  • Water reaches the house in storms

    If storm water comes up against your walls or under the door, your floor sits lower than the water gets, and raising the house is how you get above it.

  • Your flood zone may change

    The city says that if FEMA's proposed flood maps take effect, X zones will shrink, and some buildings now in them may need flood insurance for the first time.

  • Cracked or rusting piers

    Cracks or rust stains on the old piers under your house often mean the steel inside is giving out, and replacing them is a natural time to raise the house.

  • Floors that slope or doors that stick

    A floor that tilts or doors that start to bind can mean a support underneath has settled, and the fix often means lifting that part of the house anyway.

Questions about raising a house here

Start with the answers below. If your question isn't here, call (645) 300-7417 and I'll talk it through with you.

How much does it cost to raise a house in Key West?

Raising a typical single-family house usually costs about $20,000 to $80,000 per home across the US, according to a national cost guide. Coastal jobs like ours here, and jobs that replace the whole foundation, cost more than a typical raise. You get a written scope with the price after I measure yours.

Do I need a permit to raise my house in Key West?

Yes. The city requires a building permit for any structural change, whatever it costs, and raising a house is structural work. It can also require one for any work valued over $1,000 in materials and labor, at the building official's call. We handle the permit paperwork with the city's Building Department.

How long will I be out of my house during a house raising?

Plan to be out of the house for part of a project that runs six to twelve weeks, going by a national cost guide. Temporary housing rarely shows up in a contractor's bid, so give it its own line in your budget. I'll help you plan for it when we go over the estimate.

My mailing address says Key West, so who handles my flood rules?

Not always the city. Some areas with a Key West mailing address sit outside it, like Key Haven, Rockland Key and the south side of Stock Island, and the city's floodplain office refers those owners to Monroe County Floodplain Management. We check which office covers your address before anything else.

What extra steps apply to raising a historic house in Key West?

The city's historic guidelines say foundations should be repaired or replaced to match the original foundation's size and appearance. You file one combined application with the city's historic preservation office for both the building and historic review permits, so there's no separate historic application.

Is there a grant to help pay for raising my house in Florida?

The state's Elevate Florida program took applications from February 7 to April 11, 2025. That window has closed, so plan your budget on the cost and temporary housing figures above.
