Foundation installation in Key West FL - a solid base built for your flood zone

FEMA guidance recommends piles for lots in a V Zone or a Coastal A Zone, because an open foundation leaves very little in the way of moving floodwater. Check which zone your parcel is in on the city's Flood Insurance Rate Map, and we'll plan the foundation around it.

The city requires the first living floor of new construction and major renovations to sit at least 1.5 feet above FEMA's minimum base flood level. A major renovation is one that costs 50% or more of the existing building's value, and contributing structures in the Historic District are excepted, so we confirm where your house falls first.

Yes, if your parcel is in a V Zone on the city's flood map, new construction and substantial improvement or damage work need a V Zone design certificate before the first building permit. It covers the structural design and the building methods, so design comes first in your schedule.

Yes, in most cases, because the City of Key West Building Department requires a permit before work valued over $1,000, counting materials and labor, at the building official's discretion. Any development in a flood hazard area needs a permit too, including filling and grading. We handle the permit paperwork with the city when a job calls for one.

Yes, exterior work in the Historic District needs a Certificate of Appropriateness as part of the building permit application. That review is its own step, so we plan for it in the schedule from the start instead of waiting on it later.

Not always. Key Haven, Rockland Key and the south side of Stock Island can have a Key West mailing address but sit outside the city, and owners there are referred to Monroe County Floodplain Management. We work across the island and the cities around it, so we check which office covers your address first.

The city inspects a foundation once the trenches are dug and the forms are up, so plan on a pause at that point in the job. We build to the plans, stop there for the inspector, and the concrete comes after.

It shouldn't, because most bad cracking traces back to a base that was only raked level, or to control joints, the cuts that give concrete a planned place to crack, done late or skipped. We put our time into the base, the steel and the joints first, because none of it can be fixed once the house is on top.
