Commercial Construction Defect Lawyer

Defects in a commercial building do more than damage the structure. They interrupt tenants, complicate refinancing and sale, and turn a performing asset into a recurring expense. Cory Cannon represents commercial property owners, landlords, and investors across Tampa Bay in defect claims against general contractors, developers, subcontractors, and design professionals. We read the project file the way it was written, as a set of construction documents, and we litigate what it shows.

This page explains how Florida law treats defects in commercial construction: what qualifies as a defect, how your contract shapes the claim, the Chapter 558 pre-suit process, the deadlines that control, and what a commercial owner can actually recover. If you would rather talk it through first, contact us for a free consultation.

Who This Page Is For

We wrote this page for the owner side of commercial construction disputes. That includes:

• Owners of office, retail, industrial, warehouse, medical, and hospitality buildings with defective original construction or renovation work
• Landlords whose tenant improvement work was built wrong and is now generating complaints, vacancies, or lease disputes
• Investors and buyers who acquired a recently built commercial property and discovered problems the closing documents never mentioned
• Commercial tenants who paid for their own build-out and got nonconforming work

A few boundaries, so you land on the right page. If your dispute with a contractor is purely about money (unpaid invoices, disputed change orders, a contract fight with no defective work at issue), that belongs with our construction litigation practice. Broader commercial disputes, including lease and vendor fights, sit with our business litigation practice. Condominium and homeowners associations pursuing a developer should start with our condo and HOA defect page, and individual homeowners should start with our new construction defect page. Everything else about defective work in Florida lives in our construction defects hub.

What Counts as a Construction Defect in a Commercial Building

A construction defect is work that fails to conform to the contract documents, the Florida Building Code, or accepted industry standards, or a design that was flawed before anyone poured concrete. Florida law also distinguishes two categories that matter for deadlines. A patent defect is one a reasonably careful inspection would reveal, like a visibly out-of-level slab. A latent defect is hidden (a missing moisture barrier behind stucco, an unwelded seam under roof ballast) and often surfaces years after the certificate of occupancy.

In commercial buildings, the defects most often reported fall into a few families:

• Building envelope failures. Water intrusion at windows, storefront systems, curtain walls, stucco, and EIFS cladding. Water is patient; it finds the missing flashing eventually. Our water intrusion page covers these claims in depth.
• Roof system defects. Covered in detail below, because commercial roofs fail differently than residential ones.
• Structural and foundation problems. Slab settlement, cracked tilt-wall panels, movement in masonry, and soil preparation failures. See our foundation defect page.
• Mechanical, electrical, and plumbing defects. Undersized or poorly balanced HVAC that leaves conditioned space humid enough to grow mold, code-violating electrical work, and pipe installations that fail early. Our MEP defect page addresses these systems.
• Design errors. Drainage that sends stormwater at the building, structural designs that missed loads, details that could never have been built watertight. See our design defect page.
• Defective products and materials installed throughout a building. See our defective building materials page.

Commercial Roof Systems: TPO, Modified Bitumen, and Metal

Most Tampa Bay commercial buildings carry a low-slope roof: TPO (thermoplastic polyolefin, a single-ply membrane with heat-welded seams), modified bitumen (asphalt sheets applied in overlapping plies), or a metal panel system. Each fails in characteristic ways when installed wrong. TPO seams that were welded too fast or too cool peel open under thermal cycling. Modified bitumen laps and flashings that were not properly adhered wick water at every penetration. Fastener patterns that ignore the wind uplift pressures required by the Florida Building Code leave a roof that passes a walk-through but cannot hold in a design-level storm. Tapered insulation installed out of sequence leaves ponding water that shortens membrane life and voids manufacturer warranties.

These are installation and design defects, and they are provable, with core cuts, seam probes, moisture scans, and the installer’s own submittals. Our roofing defect page covers roof workmanship claims in detail. Note the distinction that controls where your claim goes: a roof that was built wrong is a claim against the contractor; a roof that a storm damaged is usually a claim on your insurance policy, which we address below.

Tenant Build-Outs and Improvement Work

Tenant improvement work (the build-out that converts shell space into a functioning office, clinic, restaurant, or store) generates its own defect disputes, and the first question is always who owns the claim. If the landlord contracted for the work, the landlord holds the contract claim even when the tenant suffers the disruption. If the tenant contracted directly under a tenant-improvement allowance, the tenant holds it. The lease usually allocates responsibility for delivery condition, code compliance, and mechanical tie-ins to the base building, and that allocation shapes who can sue whom.

Build-out defects also carry business consequences out of proportion to their repair cost. A medical suite that fails inspection cannot open. A restaurant with a noncompliant hood system cannot cook. We treat those downstream losses as part of the case from day one, because the documents that prove them (delayed openings, rent abatements, lost sublease income) have to be assembled while the evidence is fresh.

Your Contract Controls More Than You May Think

Commercial construction usually runs on formal contract documents, often AIA (American Institute of Architects) forms with the A201 General Conditions attached. Before we talk statutes, we read the contract, because several of its provisions can matter as much as any law:

• The contractor’s warranty. A201 section 3.5 warrants that the work conforms to the contract documents and is free from defects. Nonconforming work breaches this warranty whether or not anyone was negligent.
• The one-year correction period. A201 section 12.2.2 obligates the contractor to correct defective work discovered within one year after substantial completion. Owners routinely misread this as a one-year deadline to sue. It is not. It is a callback remedy (an extra obligation on the contractor), and Florida’s statutes of limitations, not the correction period, set the deadline for filing suit. Do not abandon a claim because someone told you “the warranty expired.”
• Notice provisions. Many commercial contracts require prompt written notice of claims and defects. Missing a contractual notice can hand the contractor a defense the law never gave it. When you find a defect, put it in writing early.
• Waiver of consequential damages. Most AIA general conditions include a mutual waiver of consequential damages. If yours does, lost rents and lost profits may be off the table by agreement, which changes how we value and frame the claim.
• Dispute resolution clauses. Arbitration requirements, initial decision maker procedures, and mediation prerequisites all change the path a claim takes. Chapter 558’s pre-suit process still applies where an arbitration clause conflicts with it. The statute says it controls.
• A Chapter 558 opt-out. Section 558.005 lets the parties opt out of the pre-suit process by written agreement, and some commercial contracts do exactly that. This is one of the first things we check.

Send us the contract before you send anyone a demand. Thirty minutes with the general conditions frequently changes the strategy.

The Legal Claims Available to a Commercial Owner

Florida gives a commercial owner several routes against the parties who built the building:

• Breach of contract. Work that does not conform to the plans and specifications breaches the construction contract. This is usually the core claim, and where the loss is purely economic and the parties have a contract, Florida law channels most of the dispute through it.
• Breach of warranty. Express warranties in the contract, plus manufacturer warranties on roof membranes, glazing systems, and equipment, which raise assignment and registration questions when a building changes hands.
• Violation of the Florida Building Code. Section 553.84, Florida Statutes creates a civil action for anyone damaged by a material code violation. The statute carries a defense where the work was permitted, approved, and passed inspections, but the defense fails if the violator knew or should have known the violation existed. Code claims reach parties and conduct that contract claims sometimes cannot.
• Claims against design professionals. Architects and engineers whose designs or inspections fell below professional standards can bear responsibility alongside the contractor.
• Claims against the developer or seller. Buyers of recently built commercial property may hold claims under the purchase agreement and, in the right facts, for nondisclosure of known defects.

Which claims fit, and against whom, depends on the contract chain and the evidence. Our article on suing a contractor in Florida walks through the decision points.

Chapter 558: Florida’s Pre-Suit Defect Process

Before filing most construction defect suits, Florida requires the owner to run the process in Chapter 558 of the Florida Statutes, and yes, it applies to commercial buildings, not just homes. In short, for a claim by a single commercial owner:

• You serve a written notice of claim describing each defect in reasonable detail at least 60 days before filing suit.
• The contractor, subcontractor, or design professional may perform a reasonable inspection of the property within 30 days after service. Any requested destructive testing is subject to the safeguards in section 558.004(2).
• Within 45 days, the served party must respond in writing, offering to repair, offering money, disputing the claim, or some combination.

Associations representing more than 20 parcels operate on longer timelines (120-day notice, 50-day inspection, 75-day response). The full statutory mechanics are in section 558.004, Florida Statutes, and our guide to the Florida 558 notice process explains how to use the process well rather than merely comply with it. The notice you serve frames the case: a vague notice invites a vague repair offer, while a notice built on an itemized investigation forces a real response. Serving a compliant notice also carries a deadline benefit: under section 558.004(10), service of the notice of claim tolls the applicable statute of limitations until the statutory notice and response windows close, which can preserve a claim that would otherwise lapse while the pre-suit process runs. And remember the opt-out: if your contract validly opted out of Chapter 558 under section 558.005, the process may not apply at all.

Deadlines That Control a Commercial Defect Claim

Two clocks run on every Florida defect claim, and they are different instruments. A statute of limitations is the deadline to sue measured from when the claim arises, and it can be extended for hidden defects. A statute of repose is an absolute cutoff measured from the project’s completion, and it cannot be extended, even for defects nobody could have found. Both live in section 95.11(3)(b), Florida Statutes.

Three points deserve emphasis. First, the 7-year repose is a cliff. Florida shortened it from 10 years in 2023 (SB 360), and buildings completed in the mid-2010s have already aged out. If your building was completed six years ago and a latent defect just surfaced, the remaining window is measured in months, not years. Second, the trigger is the earliest qualifying date: a temporary certificate of occupancy starts the clock even if final completion dragged on. Third, the multi-building rule cuts both ways on phased commercial projects: an early phase can be time-barred while a later phase is still open. These deadlines are fact-specific and unforgiving; treat the table as the statute’s framework, and have a lawyer run the dates for your specific project before you rely on any of them.

Business Losses: The Damages Side of a Commercial Claim

Repair cost is the starting point: what it takes to remove the defective work and rebuild it correctly, plus the investigation costs of finding the full extent of the problem. But in commercial property, the defect is rarely the whole loss. Water intrusion drives out a tenant. A failed roof forces a warehouse user to relocate inventory. A code violation delays an opening by a quarter. Depending on your contract, recoverable damages can include lost rent, rent abatements you were forced to give, tenant claims you had to absorb, and diminished property value where repair is impractical.

Two cautions. The consequential damages waiver discussed above can eliminate lost-rent and lost-profit recovery by agreement, so the contract analysis comes before the damages model. And Florida law expects an owner to mitigate, to take reasonable steps to limit the loss, so document every decision you make while the building is impaired. If your losses flow from a late project rather than a defective one, that is a different claim; see our construction delay claim page.

If Your Real Dispute Is With an Insurance Carrier

Some building failures surface first as an insurance claim: a storm opens the roof, the carrier’s engineer blames “construction defect” and denies coverage, and the contractor blames the storm. If your immediate fight is with your commercial property insurer rather than the builder, start with our commercial property insurance claim page. We handle both sides of that crossover, and when a carrier and a contractor are each pointing at the other, the investigation that answers one question usually answers both.

How We Build a Commercial Defect Case

Commercial defect cases are won in the project record. We start with the documents: the contract set, drawings and specifications, submittals, RFIs (requests for information, the written questions and answers that show what the builder knew), change orders, pay applications, inspection reports, and closeout documents. That record usually tells us what was supposed to be built, what was actually built, and who decided to deviate.

Then we test the building. We retain independent licensed engineers and consultants for moisture mapping, test cuts, roof cores, and structural evaluation, evidence that survives cross-examination because it was gathered by professionals with no stake in the outcome. And when a contractor or its insurer floats a repair number, we check it against real bids from licensed local contractors, not desk estimates.

This is the work Cory Cannon was built for. I am a Florida attorney with a family history in construction for generations. I grew up around construction, and I read a pay application, a submittal log, and a roof detail as fluently as a pleading. That upbringing does not replace the independent engineers we retain; it means I know what to ask them, and I recognize when a contractor’s story does not match the documents.

Fees for Commercial Defect Representation

We structure fees to fit the case and explain the proposed arrangement in writing before representation begins. Commercial defect matters may use hourly billing, phased flat fees for the investigation and Chapter 558 stage, a hybrid structure, or a contingency arrangement in an appropriate case. Many commercial construction contracts contain prevailing-party attorney’s fee provisions, so fee exposure can run in both directions. That issue is part of the initial case evaluation. The initial consultation is free.
