Florida HOAs and condominium associations carry a master policy covering the building and shared areas, but that policy frequently leaves the association exposed at several specific points: the named-storm sublimit, the hurricane deductible, and the treatment of flood and storm surge, which is commonly separate from wind coverage altogether. Each of these gaps has a direct financial consequence for the association, and each becomes most apparent in the period immediately following a storm.
This guide examines these gaps in turn, the reasons they arise, and how an additional layer of parametric coverage can help address them. Hurricane Ian is referenced throughout as a real-world illustration of how these gaps play out in practice.
What a Florida association's insurance program needs to cover
At the community level, a Florida association generally needs:
- A master property policy covering the building structure, shared systems, and common areas.
- Association liability coverage for incidents in shared spaces.
- Wind and named-storm coverage, which in Florida is often the single most scrutinized part of the program.
- Flood coverage, which is typically handled on separate terms from wind, and deserves its own review, especially for coastal properties.
Individual unit owners carry their own policies for interiors and belongings, with the master policy's terms determining where the association's responsibility ends and the owner's begins. Florida also maintains its own rules around how association property must be insured and how reserves are funded, so it is advisable to confirm with the board that their program meets both their governing documents and current state requirements, as these rules have changed in recent years.
None of this is unusual on its own. What tends to catch boards off guard is not this list, but what happens within each of these coverages once a real storm hits.
Pain point 1: the named-storm sublimit rarely matches the real cost of rebuilding
Wind coverage in a Florida master policy is often capped well below the building's full replacement cost. This cap is the named-storm sublimit, and it is separate from the overall policy limit. The policy pays up to that cap, and the association is responsible for any damage above it.
This is also why two buildings on the same block can end up in very different financial positions after the same storm. A wood-frame building tends to sustain real structural damage earlier in a storm, around Category 2, while unreinforced masonry tends to hold through roughly Category 3, and reinforced concrete is generally the most resilient, with its primary weak point being windows and glazing rather than the structure itself.
A sublimit set without accounting for the building's actual construction type can leave a wood-frame property significantly underfunded at the moment it needs coverage the most.
Construction type | How it tends to perform in wind | Where meaningful damage tends to begin |
Wood frame | Weaker structural resistance; exposed to flying debris and roof uplift | Around Category 2 |
Masonry / brick | Generally holds through lower-category storms; roof systems and openings become the weak point | Around Category 3 |
Reinforced concrete | Most resilient structurally; main exposure is window and glazing failure at height | Glazing around Category 3, broader damage around Category 4 |
For context on how quickly damage potential increases, the table below outlines what each hurricane category tends to mean for a multi-unit building:
Category | Sustained winds | What it can mean for multi-unit buildings |
1 | 74 to 95 mph | Roof coverings, siding, and gutters damaged on well-built structures; poorly built frame roofs and unprotected windows at risk; high-rise glass can break from flying debris |
2 | 96 to 110 mph | Substantial roof and siding damage to apartment buildings; unreinforced masonry walls can fail; high-rise windows broken by debris |
3 | 111 to 129 mph | High percentage of roof and siding damage; older unreinforced masonry can collapse; numerous high-rise windows blown out |
4 | 130 to 156 mph | Structural damage to the top floors of apartment buildings; most unprotected windows break; widespread glazing failure in high-rises |
5 | 157 mph and up | Low-rise apartment buildings can be destroyed; most masonry walls can fail; nearly all high-rise windows blown out |
The practical implication for a board is that the named-storm sublimit warrants as much attention as the headline policy limit, as it is ultimately the figure that determines how much of the rebuild the association must fund itself.
Pain point 2: the hurricane deductible can be a bigger shock than the sublimit
Florida associations commonly carry a percentage-based hurricane deductible rather than a flat dollar amount. Depending on the building's value, this can translate into a substantial sum the reserve fund must cover before the policy pays anything. Boards sometimes discover the true size of this figure only after a storm has occurred, which is an unfortunate time to learn it.
In many communities, a portion of this deductible can be passed on to unit owners through a loss assessment under the governing documents. This is one reason it is worth reminding owners to carry loss assessment coverage on their own policies, though it does not resolve the association's cash flow needs in the days immediately following the storm.
Pain point 3: flood and storm surge are usually a separate, and much smaller, coverage
This is the gap that catches the most boards by surprise. Wind and flood are typically treated as two distinct problems within a Florida master policy. Flood coverage is often excluded from the master policy entirely, or written under its own sublimit that is unrelated to the wind coverage and is usually considerably smaller.
For coastal associations, this matters more than nearly anything else in the program, because storm surge, the wall of water a hurricane pushes ashore, is often the single largest source of loss in a major hurricane, and a wind-only policy does not respond to it.
Hurricane Ian illustrates this clearly. When Ian made landfall near Fort Myers in September 2022 as a Category 4 storm, it drove a storm surge of roughly 15 feet, sufficient to destroy sections of the roadway connecting Sanibel Island to the mainland. Coastal resorts and communities in the surge zone sustained significant property damage and lost substantial revenue while closed for repairs. None of this flood and surge damage would have been addressed by a wind-only policy, regardless of how strong that policy's wind terms were.
This point is worth conveying directly to boards: an assumption that flood is "handled" elsewhere in the policy, once the named-storm wind sublimit has been reviewed, is often incorrect, and Hurricane Ian demonstrates why.
Pain point 4: even a well-structured policy can take too long to pay
There is a fourth gap that is easy to overlook, as it concerns timing rather than coverage amounts. After a storm, an association needs cash quickly to secure the property, pay vendors, and keep residents informed and housed. Traditional claims settlement, even under a strong policy, can take months. This gap between the storm's occurrence and the arrival of funds is where boards deplete reserves, delay repairs, and lose residents' confidence.
How an added layer of parametric coverage helps close these gaps
This is where Descartes can support the broker relationship you already hold with the client. Descartes designs additional layers of parametric coverage that sit alongside the master policy and are structured to pay out quickly, based on the storm's measured wind speed or measured water level, rather than a traditional damage assessment. It is best understood not as a replacement for the master policy, but as a fast-paying supplement aimed specifically at the gaps described above.
On the wind side
Descartes can structure a windstorm parametric layer that pays based on how close a hurricane's track passes to the property and how strong its winds are at that point, using storm data that is publicly tracked and verified rather than a site inspection. The layer is established in advance with agreed payout amounts tied to specific wind speed and distance combinations, so there is no dispute afterward about what is owed.
For example, a program might be structured so that a Category 4 storm passing within 10 miles of the property triggers a payout equal to 40 percent of the sum insured, paid automatically once the storm's path and intensity are confirmed. On a $10 million sum insured, that amounts to $4,000,000, arriving without waiting on an adjuster's assessment.
This type of layer can help in several concrete ways:
- It brings faster cash to the association after a storm, often within days to a few weeks.
- It can be used to cover the master policy's deductible, so the reserve fund is not the first source of cash after a storm.
- It can help close the gap left by the named-storm sublimit, bringing total wind protection closer to the building's real value.
- Because the wind layer often responds even to flood-driven losses tied to the same storm, it can offer some broader protection beyond wind alone, although it is not a substitute for dedicated flood coverage.
On the flood and storm surge side
Descartes can also build a dedicated storm surge parametric layer that pays based on the modeled water level at the property during a storm, independent of the storm's wind category.
Returning to the Hurricane Ian example, a resort with an $80 million storm surge layer facing a surge exceeding 9 feet, close to what Ian produced, would see that layer pay out in full, funding debris removal, repairs, and lost revenue within days, well before a traditional claim would typically be finalized.
For many coastal Florida communities, the strongest program combines both: a windstorm layer for broad protection and speed, and a dedicated storm surge layer for the properties most exposed to water.
Descartes structures each layer around the specific building. A wood-frame coastal building and a reinforced concrete tower a block away do not receive the same terms, as they do not face the same risk, and the same principle applies to flood terms for a beachfront property versus one set back from the water. The objective is a payout that tracks what the community would realistically lose, rather than a generic template.
What we typically need to prepare a parametric quote
To scope a windstorm or storm surge layer for a client, we generally require:
- The property's location, address, or GPS coordinates.
- Loss history for the property.
- The desired policy limit.
A note on wildfire exposure
Wind and flood dominate the picture for Florida associations, but for portfolios that extend outside the state, or for panhandle and inland communities near forested land, wildfire is worth noting as well. A wildfire layer operates on the same logic as the wind and storm surge coverage: it pays out once a wildfire crosses a predefined boundary around the property, typically 100 meters out, confirmed using satellite imagery rather than an on-site adjuster. This is especially useful for associations that have been placed into a state residual market, as those programs typically insure the structure only and exclude landscaping, shared amenities, and evacuation costs.

How this works with you as the broker
Descartes designs the parametric layer. You retain the client relationship and remain their single point of contact. Our role is to provide a clear, credible answer to the wind gap and the flood gap that a standard master policy leaves open, allowing you to bring your client a solution rather than simply a diagnosis of the problem.
In practice, this means:
- A layer built around the client's building, rather than a generic template. Construction type, coastal exposure, and budget all shape the structure.
- A payout designed to track real exposure, so the coverage aligns with the loss the community is genuinely likely to face.
- Fast, transparent cash, with the trigger and payout agreed in advance and no loss-adjustment process to wait through, so funds can reach the association within days to a few weeks.
- A partner to you, not a competitor for the relationship. The technical design work sits with Descartes, allowing you to remain focused on the client.
Descartes was founded in 2019 with a focus on protecting organizations against climate and catastrophe risk, and works with brokers globally. For a Florida association, the practical point is straightforward: added layers of wind and storm surge coverage that pay quickly, are easy to explain to a board, and are built around the specific building and the specific gap it faces.
