Florida Foundation Defect Lawyer

Foundation cracking, settling, or structural movement in a newer Florida building is usually a construction defect, and a claim you can pursue against the builder, the site-work contractor who prepared the ground, and the design professionals who engineered the foundation. Two deadlines control it: a four-year period to file suit, and an absolute seven-year statute of repose that can end the claim whether or not you ever had a chance to discover the problem. The sooner the movement is diagnosed and the dates are checked, the more options you keep.

Foundation problems rarely announce themselves. They show up as small symptoms: a stair-step crack working through the stucco, a bedroom door that no longer latches, a tile floor that slopes toward one corner of the house. The cause is usually below the slab: fill soil that was never compacted, buried organic material that is slowly decomposing, or a footing designed for conditions that do not exist on your lot.

Cory Cannon represents homeowners, commercial property owners, and condominium and homeowners associations across Tampa Bay in foundation and structural defect claims against builders, developers, site-work contractors, and design professionals. I am a Florida attorney with a family history in construction for generations, and I approach these cases the way they should be approached: diagnose the physical cause first, then build the legal claim around the evidence. Foundation and structural defect work is one part of our broader construction defect practice.

This page explains how to tell settlement from a sinkhole, what causes foundation defects in Florida, who is legally responsible, and the deadlines that control your claim. A consultation is free.

Settlement or Sinkhole? Get the Diagnosis Right First

Tampa Bay sits on karst geology: limestone that groundwater slowly dissolves. Because of that, many local owners assume any cracking or settling means a sinkhole. Usually it does not. Most foundation movement in newer construction is differential settlement: one part of the foundation sinking more than another because the soil under it was poorly prepared. That is a construction defect claim against the builder and the parties who did the site work, and it is the subject of this page.

True sinkhole activity is a different legal path. Under section 627.706, Florida Statutes, every Florida property insurance policy must cover "catastrophic ground cover collapse," and insurers must make optional "sinkhole loss" coverage available for structural damage caused by sinkhole activity. If your foundation damage traces to sinkhole activity (or your insurance carrier is disputing whether it does), that dispute runs against the insurer, not the builder, and it belongs with our property insurance claims practice. The physical investigation looks similar in both cases. The defendants, the statutes, and the deadlines are entirely different, which is why the diagnosis has to come first. We handle both sides of that line and can tell you which one your case is on.

Signs of a Foundation or Structural Defect

Not every crack is a defect. Concrete shrinks as it cures, and hairline surface cracks are normal in Florida slabs and stucco. What matters is the pattern, the width, whether the two sides of a crack are displaced, and whether the crack is growing. These are the signs that point to real movement:

• Stair-step cracks in concrete block or brick that follow the mortar joints diagonally. This is the classic signature of differential settlement.
• Horizontal cracks in a stem wall or foundation wall, which can indicate lateral soil pressure or a failing footing.
• Slab cracks with vertical offset: one side of the crack sits higher than the other. Displacement means movement, not shrinkage.
• Doors and windows racking out of square. Frames distort when the structure around them moves. Drywall cracks radiating from the corners of openings tell the same story.
• Sloping or dished floors. A floor that measurably drops toward one area matters far more than one that merely "feels" off. Engineers quantify this with a floor elevation survey, described below.
• Separations: baseboards pulling away from floors, crown molding gapping at the ceiling, cracked tile running in a continuous line across rooms.
• Exterior tells: stucco cracks concentrated at window and door corners, separation where an addition or garage meets the main structure, gaps opening at the roofline.

If you are seeing several of these together, photograph them with a date stamp, measure crack widths, and do not let anyone patch them before they are documented. Patching destroys the evidence that dates and diagnoses the movement.

What Causes Foundation Defects in Florida

Poorly prepared soil

This is the most common cause we see. Florida building sites are rarely built on undisturbed ground. Lots are cleared, filled, and graded, and the fill must be placed in controlled layers (called lifts) and compacted to a specified density, verified by field density testing. When a site-work contractor skips lifts, buries land-clearing debris or tree stumps, leaves organic soil (muck) in place, or a testing lab signs off on compaction that never happened, the ground under the slab consolidates over the following years. The house settles unevenly, and the structure cracks as it tries to bridge soil that is no longer supporting it. Uniform settlement rarely damages a building. Differential settlement almost always does.

Geotechnical and design errors

A geotechnical engineer (the engineer who drills soil borings and characterizes what the ground can support) feeds data to the structural engineer who designs the foundation. Errors compound at this stage: borings that missed a pocket of unsuitable soil, a report that mischaracterized the water table, a footing designed with too little bearing area, or a shallow foundation specified where the soils called for deep foundations or ground improvement. When the failure originates on paper rather than in the field, the claim runs against the design professionals, and it is analyzed the way we describe on our design defect page.

Slab and concrete construction problems

Most Florida homes sit on a slab-on-grade foundation, often poured monolithically with the footings. Some are post-tension slabs, which contain steel tendons that are stressed after the concrete cures to keep the slab in compression. Construction-stage failures include concrete that never reached its specified strength, reinforcing steel that was omitted or ended up in the wrong position, tendons stressed improperly or too early, and cold joints where pours were interrupted. These defects are invisible at closing and surface as cracking and movement years later.

Framing and truss defects

Structural problems are not limited to the ground. Florida roofs are framed with engineered trusses, and the load path (the continuous chain that carries roof loads down through walls to the foundation) depends on connectors and straps installed exactly as the plans require. We see missing or wrong-size hurricane straps, trusses cut or drilled in the field without an engineer’s approval, point loads landing on framing with no bearing below them, and truss uplift: seasonal movement of truss chords that opens recurring cracks where interior walls meet the ceiling. Framing and truss defects are structural defects, and they belong in the same claim as foundation problems when both trace to the original construction.

Water and drainage

Grading that slopes toward the house, roof drainage discharging at the foundation, and failed site drainage all move soil. Erosion undermines footings; repeated wetting and drying cycles change how soil supports load. Where water is also entering the building through the envelope (walls, windows, or the roof), that overlapping problem is covered on our water intrusion page.

Who Is Responsible for a Foundation Defect

Foundation and structural failures usually have more than one author. Part of building the case is allocating responsibility among them:

• The general contractor or builder. The builder is responsible for delivering a code-compliant structure, including the site preparation and foundation work it performed or supervised. For homes bought new from the builder, Florida law also implies warranties of fitness and habitability, which we explain on our new construction defect page.
• The site-work or grading contractor that placed and compacted the fill.
• The geotechnical engineer whose borings and report defined what the foundation was designed for.
• The structural engineer of record who designed the foundation and framing.
• The truss manufacturer, where the engineered trusses themselves were defectively designed or fabricated.
• The developer, particularly in community-wide settlement problems, where the same site preparation failures repeat lot after lot.

For condominiums and HOA communities, foundation and structural movement often affects common elements and multiple units, and the association (not individual owners) typically holds the claim after turnover from the developer. That process has its own rules and its own clock, covered on our condo and HOA defect page. Structural movement in balconies and elevated walkways raises separate life-safety issues, addressed on our condo balcony structural defect page.

How We Investigate a Foundation Claim

A foundation case is won on physical evidence and documents, in that order. Our investigation follows a consistent sequence.

Documents first. The building department file is public record: permits, approved plans, inspection results, and certificates of occupancy. From the builder and its subcontractors we pursue the geotechnical report, the compaction and density test results, the foundation and truss engineering, and pour records. In a surprising number of settlement cases, the paper trail shows the problem was known (or should have been) before the slab was ever poured.

Then the physical work. We retain independent licensed engineers (structural and geotechnical) to diagnose the movement. The standard tools are a floor elevation survey (a manometer survey, which maps the slab’s high and low points to fractions of an inch), crack mapping with monitors that record whether cracks are still moving, and new soil borings to test what is actually under the foundation against what the original report claimed. Where the numbers disagree, the case usually follows.

Then the repair scope. Builders responding to a foundation complaint often propose cosmetic fixes: epoxy injection, patching, paint. Real remediation of a settlement problem (underpinning with helical or push piers, compaction grouting, partial slab replacement) is a different order of magnitude. I grew up around construction, and I read repair scopes line by line. When a builder’s offer does not match the independent engineer’s repair recommendation, we price the correct scope against real bids from licensed local contractors and demand the difference.

The Legal Framework: Chapter 558, the Building Code, and Your Contract

The Chapter 558 pre-suit process

Florida requires most construction defect claimants to go through a pre-suit notice process under chapter 558, Florida Statutes, before filing suit. In brief: you serve a written notice of claim describing the defect at least 60 days before filing an action (120 days for an association representing more than 20 parcels). The builder then has 30 days to inspect (50 for larger association claims) and 45 days to serve a written response (75 for larger association claims) offering to repair, offering money, proposing a combination, or disputing the claim. The notice has to be done correctly. An imprecise notice weakens the claim it is supposed to set up. We walk through the process step by step, for both owners and contractors, in our guide to the Florida 558 notice.

Building code violations: section 553.84

Foundation, concrete, and structural framing work are heavily regulated by the Florida Building Code, so code-based claims fit these cases naturally. Section 553.84, Florida Statutes, gives anyone damaged by a material violation of the code a civil cause of action. A material violation is one that may reasonably result, or has resulted, in physical harm to a person or significant damage to the performance of the building or its systems, a description that fits most genuine foundation defects. There is a defense where the contractor pulled permits, had the plans approved, passed all required inspections, and the damage is confined to the permitted property itself, and even then it does not apply if the contractor knew or should have known the violation existed. Compaction that was never performed, or steel that was never placed, is hard to characterize as innocent.

Contract, warranty, and professional negligence claims

Alongside the code claim, foundation cases typically include breach of contract against the builder, breach of the implied warranties that Florida law attaches to the sale of a new home by a builder-seller, and professional negligence claims against the geotechnical and structural engineers. Which claims fit, and against whom, depends on your contract and your position in the chain. Our overview of suing a contractor in Florida maps the options.

Deadlines: The Four-Year Clock and the Seven-Year Cliff

Two clocks control every Florida construction defect claim, and the Legislature shortened one of them in 2023. The statute of limitations is the deadline to sue once a claim exists. The statute of repose is an absolute outer cutoff that runs whether or not you know about the defect.

Under section 95.11(3)(b), Florida Statutes (formerly numbered 95.11(3)(c), older articles still use that citation), an action founded on the design, planning, or construction of an improvement to real property must be filed within four years. The clock starts on the earliest of: issuance of a temporary certificate of occupancy, issuance of a certificate of occupancy, issuance of a certificate of completion, or abandonment of the project if construction never finished.

The distinction between patent and latent defects matters here. A patent defect is one that is apparent, or discoverable by reasonable inspection. A latent defect is hidden, and most foundation defects are latent, because the failed compaction or missing steel sits under a finished slab. For latent defects, the four-year clock runs from when you discovered the defect or should have discovered it with due diligence.

The discovery rule has a hard ceiling: the statute of repose. Senate Bill 360 (2023) cut Florida’s repose period from ten years to seven years, measured from the same earliest-of trigger events. After seven years, a defect claim is extinguished even if the defect was impossible to detect. Two related rules from the same statute: on multi-building projects, each building is treated as its own improvement for computing the deadlines, and for a home first used as a builder’s model, the clock starts on the date a deed is first recorded transferring title to another party.

These calculations are fact-specific: the trigger dates come from building department records, and transition rules from the 2023 legislation can affect older projects. If your building is more than a few years old and you are seeing movement, have the dates checked now. Do not rely on a table, including this one, without counsel confirming your specific dates.

What You Can Recover

The usual measure of damages in a foundation defect case is the cost to repair the defect correctly (the engineered remediation, not the cosmetic patch) together with the damage the movement caused to finishes, flooring, and other property. In some cases the measure is the loss in the property’s value instead, and investigation costs and certain consequential losses may be recoverable depending on the claims and the contract. What is available in your case depends on your documents and your facts, and we will tell you plainly what we see after reviewing them.

Fees and Costs

We handle owner-side foundation and structural defect claims on contingency or hybrid fee structures in appropriate cases, which means the fee is tied to the recovery rather than billed by the hour. Many construction contracts also contain prevailing-party attorney fee provisions, and Florida law generally makes a one-sided fee clause enforceable by both sides, which can shift fees to the builder in a successful claim, and is also a risk factor we will explain candidly. You will have the fee structure in writing before we begin.
