Private and Excess Flood Insurance for Florida Commercial Property: What Those Policies Actually Pay

Short answer

Why commercial owners buy private flood, and what changes when they do

The NFIP General Property Form caps a non-residential building at $500,000 and its contents at $500,000, pays actual cash value only, and excludes business income, extra expense, and every other economic loss. An apartment building with five or more units is capped at $500,000 for the building and $100,000 for contents. Private flood policies, written by admitted carriers, surplus lines carriers, and Lloyd's syndicates, go above those limits, can be written on a replacement cost basis, can include business income and extra expense, and can sit inside a blanket property program as a flood sublimit. In exchange, the claim is governed by the policy wording and Florida law rather than FEMA's regulations. There is no FEMA appeal, suits are in state court, and the carrier is subject to Florida's claims-handling deadlines and remedies. Read the declarations for the flood sublimit, the zone-based sub-sublimit, the deductible, and whether time element coverage is inside the flood limit.

Why NFIP stops at $500,000 for a business

FEMA's regulation at 44 CFR 61.6 sets the Regular Program maximums: $500,000 building and $500,000 contents for a non-residential building, $500,000 building and $100,000 contents for other residential buildings including apartments of five or more units, and $250,000 per unit for a residential condominium building. Those are per building, per policy. A ten-building apartment complex can carry ten policies, but no building gets more than $500,000.

The General Property Form settles every loss at the least of the amount of insurance, the actual cash value, or the cost to repair or replace. There is no replacement cost option for a commercial building under the NFIP. Section V.A excludes loss of revenue or profits, loss of access, loss of use, loss from interruption of business or production, and any other economic loss. A restaurant closed for three months after a flood has no income claim under the NFIP. Those two gaps, limits and income, are why the private market exists for commercial property.

Who buys private primary and excess flood

Lenders drive the first layer. For a loan secured by a building in a Special Flood Hazard Area, federal flood insurance regulations require coverage equal to the lesser of the outstanding principal balance or the maximum available under the NFIP for that building type, with the NFIP maximum itself limited to the building's insurable value. For a $4 million loan on a $6 million warehouse in an AE zone, the lender's minimum is $500,000, because that is the NFIP cap. Everything above that is the owner's decision, or the lender's underwriting requirement, and it comes from the private market as excess flood over the NFIP policy or as private primary flood that replaces it.

Larger owners handle flood differently. A hospital system, a multi-state hotel operator, a REIT with a schedule of shopping centers, or a self-storage platform typically carries a blanket property program with flood as a covered peril subject to an annual aggregate sublimit, and a smaller sub-sublimit for locations in high hazard flood zones. In that structure there may be no separate flood policy at all. The flood claim is a claim under the property program, adjusted by the property carrier's adjuster, subject to the program's deductible and the sublimit.

Mid-size owners, the ones with one to twenty buildings, usually end up with one of three structures: NFIP primary plus a private excess flood policy, a private primary flood policy with higher limits in place of the NFIP, or a flood endorsement on the commercial package policy with a stated sublimit. Each pays differently. Know which one you have before the water comes in.

Who writes it

The commercial private flood market in Florida is a mix of specialty carriers, large property insurers, and Lloyd's capacity. Based on what we could verify as of November 2, 2026:

• Neptune Flood, based in St. Petersburg, writes private primary and excess flood on commercial, residential, and condominium association buildings with limits up to $15 million per building, and business interruption coverage up to $1 million, after increases announced in June 2026. Neptune is a Lloyd's coverholder and places its capacity with Lloyd's syndicates.
• Lloyd's of London syndicates provide the capacity behind many private flood programs sold through coverholders and surplus lines brokers in Florida, including excess flood programs above NFIP limits. Lloyd's paper is surplus lines in Florida, which affects the guaranty fund and some statutory protections.
• FM Global writes flood as a covered peril inside its all-risk commercial property policies for large industrial and institutional accounts, subject to flood sublimits and high hazard flood zone sub-sublimits. Its flood sublimit wording has been litigated in major cases, including the Superstorm Sandy dispute with New York University.
• Zurich North America has written excess flood for commercial accounts and appears on state lists of carriers offering flood coverage on commercial lines. Confirm current appetite with a broker.
• Liberty Mutual participates in the NFIP Write Your Own program, appears among commercial private flood writers in industry market studies, and in February 2026 launched a parametric flood product with Floodbase for the U.S. commercial market, which pays on a measured water depth trigger rather than adjusted damage.
• Palomar writes commercial flood with limits up to $15 million through its excess and surplus lines company. Its published state list for commercial flood did not include Florida when we checked, so confirm availability with your broker.
• Chubb and AIG are large commercial property writers that handle flood inside property programs for their insureds, and both have offered excess flood products over the years. We could not verify a current standalone commercial flood product for either in Florida, so treat them as program carriers rather than flood specialists.

Business income and extra expense under private flood

This is the coverage the NFIP does not sell, and it is the coverage that determines whether a flooded business survives. Private flood policies that include business income typically pay the net income that would have been earned plus continuing normal operating expenses, including payroll, during the period of restoration, and extra expense to keep operating from a temporary location. Standalone private flood policies tend to offer it as a stated dollar limit, with Neptune's current maximum at $1 million. Blanket property programs pay time element losses under the program's business income coverage, but read the flood sublimit carefully. Carriers argue, and some courts have agreed, that a flood sublimit caps all flood-related loss including business income, not just property damage. The NYU case against FM Global turned on exactly that question, and the court read the sublimit to include time element claims.

Documentation for a business income claim starts the day of the flood: the prior 24 to 36 months of profit and loss statements, sales tax returns, payroll records, the lease, and a written restoration timeline from the contractor. If the policy has a waiting period deductible on business income, typically expressed in hours or days, the clock starts at the time of direct physical loss, so fix that time in the incident report.

Waiting periods, deductibles, and the named storm trap

A new NFIP policy generally has a 30-day waiting period, with an exception when the policy is bought in connection with a loan closing. Private flood carriers set their own, commonly 10 to 14 days, and some waive it for a real estate closing or a rollover from an existing policy. The flood-in-progress rule applies either way: a loss from a flood that began before the policy took effect is not covered. A building owner who bought private flood on October 20 for the late October tides should read the effective date and the flood-in-progress clause before filing.

Deductibles are where private commercial flood diverges most from the NFIP. Standalone private flood policies usually carry a flat dollar deductible per building, often higher than the NFIP options. Blanket programs commonly apply a percentage deductible to flood, calculated on the total insured value of the affected location, and a separate, often larger, percentage deductible for named storms. The named storm trap works like this: if a flood is caused by rain or surge from a named tropical system, the named storm deductible can apply to the flood loss even though it is a flood, depending on the policy's wording, and a Florida appellate court has held exactly that in a Hurricane Irma dispute. The October 2026 king tides and the November 2 rain were not named storms. For those events the ordinary flood deductible, not the named storm deductible, should apply. Say so in writing early if the carrier's acknowledgment letter reserves the named storm deductible.

Sublimits by flood zone

Large property programs rarely give full limits for flood. A typical structure is a program-wide flood sublimit, say $100 million, with a smaller sub-sublimit for locations in high hazard flood zones, meaning FEMA Special Flood Hazard Areas (zones beginning with A or V) or the carrier's own flood model. Published examples include a $200 million flood limit reduced to $50 million for property in a Special Flood Hazard Area. Which sublimit applies depends on how the policy defines high hazard, whether the location was in that zone at the time of loss, and whether a FEMA map change moved it. A Tennessee appellate decision applied the lower high hazard sublimit because the property was in a designated high hazard flood zone at the time of the loss.

For a Florida owner, two things to check now, before a claim. First, pull the current FEMA flood zone for each location and compare it to the schedule the broker submitted at renewal. Second, read whether the sublimit is per occurrence or annual aggregate. An annual aggregate flood sublimit that was partly used by an earlier loss in the policy year is smaller than the declarations suggest. With king tide cycles coming November 22 to 29 and December 22 to 27, a coastal schedule could see two floods in one policy year.

How a private flood claim is adjusted differently from NFIP

On an NFIP claim, FEMA's regulations control: 60-day proof of loss from the date of loss, FEMA appeal within 60 days of a denial, suit in federal court within one year, and no extra-contractual damages. On a private flood policy in Florida, the policy and state law control. Florida's claims-handling statute, section 627.70131, requires the insurer to acknowledge a claim communication within 7 calendar days, begin the investigation within 7 days of receiving proof of loss statements, physically inspect within 30 days of those statements, send a copy of any detailed estimate within 7 days of generating it, and pay or deny the claim or a portion of it within 60 days of notice, with a written explanation. Late payments carry statutory interest from the date of notice. The 60-day pay-or-deny rule applies to residential policies and to commercial property structure or contents claims where the insured structure is 10,000 square feet or less, and it does not apply to policies covering non-residential commercial structures in more than one state. A large single-state commercial building above 10,000 square feet falls outside the 60-day rule, though the acknowledgment and good-faith handling duties still apply. The Office of Insurance Regulation can extend insurer deadlines by up to 30 days during a Governor-declared state of emergency, which is in effect for Brevard, Indian River, St. Lucie, Martin, Highlands, Hardee, and DeSoto counties under Executive Order 26-227 signed November 2, 2026. That order is a state order, not a Presidential disaster declaration, and it does not open FEMA Individual Assistance.

Proof of loss works differently too. Most private commercial property forms require a signed and sworn proof of loss within 60 days after the insurer requests one, not within 60 days of the loss. Read the duties-after-loss condition and every carrier letter for a request and a date. Appraisal follows the policy's own appraisal clause and Florida appraisal case law, and the carrier may or may not have a right to demand it. Florida's Department of Financial Services mediation program under section 627.7015 is available for personal lines and commercial residential policies, which includes an apartment building or a condominium association's private flood policy, but not for commercial coverages on a dealership, hotel, or warehouse. And unlike an NFIP claim, Florida's statutory and common law remedies for an insurer's unreasonable claims handling are not displaced by federal law. Whether and how to pursue them is a question for an attorney.

Apartment communities, hospitals, dealerships, hotels, and storage

Apartment complexes with many buildings. Under the NFIP each building is its own policy with a $500,000 cap and $100,000 for contents, and vacancy losses are not covered. Under a private program the schedule, the per-building values, and the blanket limit matter. Document each building separately from the start: waterline, units affected by floor, electrical and mechanical rooms, laundry equipment, and the leasing office. Rent loss is the business income claim, and it requires the rent roll on the date of loss and the move-out and concession records afterward.

Hospitals and medical office buildings. Imaging equipment, generators, switchgear, and sterile processing are the dollars. Carriers will ask for the equipment schedule, service contracts, and the manufacturer's assessment of whether water-exposed equipment can be recertified. Health First cancelled elective surgeries at its Brevard hospitals on November 2 and 3, which is the kind of operational record that supports a time element claim.

Auto dealerships. Floor-plan vehicles are not covered by any flood policy on the building. They are an inland marine or dealer open lot claim, usually with a separate flood sublimit and per-vehicle deductible. The building, the service equipment, the lifts, the parts inventory, and the lost service and sales income are the property and flood claim. Keep them in separate files from day one.

Hotels. Guest room contents, the laundry, the kitchen, the elevators, the pool equipment (excluded under NFIP, often covered under private), and the lost room revenue. The business income claim should be built on STR or occupancy reports and the prior year's same-period revenue.

Self-storage. The building and the operator's equipment are the owner's claim. Tenants' goods are not covered by the owner's flood policy and are generally not the owner's claim at all. Notify tenants in writing promptly, document which units took water, and preserve the gate and access logs.

Documentation for a large commercial flood loss

• A dated incident report fixing the time water entered each building, how high it rose, and when it receded. Tide gauge and rainfall data for the location, saved as PDFs.
• Waterline photographs and video in every room, mechanical space, elevator pit, and exterior wall, with a tape measure in frame, before anything is removed.
• A moisture map from the drying contractor, with daily readings until dry standard is reached. This defends against the mold exclusion and supports the drywall and flooring scope.
• Equipment inventory with make, model, serial number, installation date, and the vendor's written assessment of repair versus replacement, especially for electrical switchgear, elevators, HVAC, kitchen equipment, and medical or production equipment.
• Contents and stock inventory with cost records. For stock, the purchase invoices and the inventory system export as of the date of loss.
• Mitigation invoices: pumping, extraction, drying, debris, temporary power, security, and board-up. These are usually covered and they prove the timeline.
• The current flood zone determination for each location and the statement of values the broker submitted at renewal, to settle the sublimit question early.
• Financial records for business income: 24 to 36 months of monthly profit and loss, sales tax returns, payroll, leases and rent rolls, reservation or occupancy reports, and a contractor's written restoration schedule.
• Every carrier communication, including the acknowledgment date, the adjuster's name and license number, the inspection date, and the estimate copy date, measured against the section 627.70131 timelines.

Where a Florida public adjuster fits on a commercial flood claim

A large commercial flood claim is a documentation project with a deadline problem. The carrier's adjuster, whether NFIP or private, is building the carrier's file. A Florida licensed public adjuster builds the policyholder's: the building-by-building scope, the equipment assessments, the separation of flood damage from any wind or rain damage that belongs on the property policy, the business income workup, and the sublimit and deductible analysis so the number presented is the number the policy actually owes. On a private flood claim the public adjuster also tracks the insurer's statutory deadlines and documents every missed one.

James Coyne handled commercial losses on the carrier side before he opened Coyne Commercial Group, which helps in reading a flood sublimit schedule the way the carrier's examiner will. A public adjuster does not give legal or tax advice, does not promise an outcome, and on an NFIP claim is paid by the policyholder, not the program. Under section 626.854(7), Florida Statutes, a policyholder may cancel a public adjuster contract for any reason, without penalty, within 10 days after signing, and for a claim arising from an event under a Governor's state of emergency declaration, such as the Brevard County flooding under Executive Order 26-227, within 30 days after the date of loss or 10 days after signing, whichever is longer.
