Insuring a high-value Florida home against hurricanes and wind

Replacement cost vs. market value in high value home insurance in Florida

The first number on a homeowners policy is the dwelling limit, often called Coverage A. For a high-value home in Florida, that limit should reflect what it would cost to rebuild the house with materials and workmanship of similar kind and quality, not the price it would sell for⁵. Market value includes the land, the view and the location, none of which needs to be rebuilt. Rebuilding cost, by contrast, reflects custom finishes, impact-rated glass and the labor premium that tends to follow a major hurricane.

Rebuilding costs also move. Verisk estimated that U.S. residential reconstruction costs rose about 25.9% from March 2020 to May 2023⁶. A limit set years ago can fall behind. Research on the 2021 Marshall Fire in Colorado found that 74% of policyholders who filed claims after the fire were underinsured, and 36% were severely underinsured⁷. The event was a wildfire, but the lesson applies to hurricanes: a total loss exposes limits that looked adequate on paper.

Extended and guaranteed replacement cost

Because any estimate can miss, many high-value policies add a cushion above the dwelling limit. Extended replacement cost pays a set percentage over the limit, which varies by policy⁴. Guaranteed replacement cost pays what it costs to rebuild the home as it was before the loss, even above the limit⁴. Conditions vary: some versions require insuring to the insurer's valuation, reporting major renovations or rebuilding at the same location.

Florida law also shapes how replacement cost is paid. Insurers must offer replacement cost coverage on the dwelling. On a total loss, they must pay replacement cost without holding back depreciation. On a partial loss, they must initially pay at least the actual cash value of the loss, less the deductible, and pay the remaining amounts as repairs are performed³.

The Florida hurricane deductible: how the math works

Under Fla. Stat. 627.701, insurers must offer hurricane deductible options of $500, 2%, 5% and 10% of the dwelling limit, with variations for higher-value homes; for example, the $500 option is not required when the dwelling limit is $250,000 or more, and the 2% option is not required at $3 million or more¹. The deductible applies once per calendar year to hurricane losses with the same insurer or insurer group. If a second hurricane causes a loss in the same year, the deductible for it is the greater of the remaining hurricane deductible or the deductible for other perils^1,2. When a hurricane deductible applies, no other deductible under the policy applies².

Florida law defines the hurricane period as beginning when the National Hurricane Center issues a hurricane warning for any part of Florida and ending 72 hours after the last hurricane watch or warning for any part of the state ends¹². Because the deductible is a percentage, the dollar amount grows with the home. Imagine a hypothetical home with a dwelling limit of $3,000,000:

A higher percentage typically lowers the premium, but the family then absorbs most of the damage from a moderate storm: roof repairs, screen enclosures, landscaping and water intrusion. The right level depends on liquidity, not on a rule of thumb. Some families keep a reserve equal to the deductible; others choose a lower percentage and a higher premium.

Ordinance or law coverage: rebuilding to current code

After a major loss, a home generally must be rebuilt to the codes in force at the time of the rebuild. In Florida that can mean stronger roof-to-wall connections, impact-rated openings, updated electrical and plumbing, or elevation requirements in flood zones. A replacement cost payment alone may not include those upgrades. Florida law requires insurers to offer ordinance or law coverage limited to 25% or 50% of the dwelling limit, as selected by the policyholder, and the 25% level is included unless the policyholder rejects it in writing³.

For older or waterfront homes, the gap between replacement cost and code-compliant cost can be large. Many ordinance or law endorsements have three parts:

• The value of the undamaged portion of the building that must be torn down because of a code requirement.
• The cost to demolish that undamaged portion and remove the debris.
• The increased cost to build to current code, beyond ordinary replacement cost.

Roof age and wind mitigation

Under Fla. Stat. 627.7011, an insurer may not refuse to issue or renew a homeowners policy solely because of the age of a roof that is less than 15 years old. For a roof 15 years or older, if an inspection by an authorized inspector shows at least 5 years of useful life remaining, the insurer also may not refuse solely because of age³. That rule is about eligibility, not about how a roof claim is paid, so it is worth asking whether the policy pays roof damage at replacement cost or on a depreciated basis.

Florida also requires residential rate filings to include actuarially reasonable discounts, credits or other rate differentials for features shown to reduce windstorm loss, such as roof strength, roof covering performance, roof-to-wall strength and opening protection⁸. Those features are documented on the uniform mitigation verification form OIR-B1-1802, completed by an authorized inspector. The form is valid for up to five years if no material changes are made to the structure, and an updated version took effect April 1, 2026⁹.

• Roof permit and installation date, and the product used.
• The most recent wind mitigation form, and a new one after any roof or opening upgrade.
• Photos of roof straps or clips, shutters or impact windows, and invoices for those upgrades.

Second homes, rentals and vacancy

Many families own more than one property in Florida. A policy written for an owner-occupied primary residence typically assumes the owner lives there. When a property is rented to others, whether long term or seasonally, the appropriate form is often a landlord or dwelling policy, which can cover the building, the owner's liability and lost rental income. Short-term rentals raise separate questions that many standard forms do not address.

Seasonal homes raise a different issue: vacancy. Most homeowners policies include a vacancy clause that limits or excludes coverage if the property is unoccupied for typically 30 to 60 consecutive days, particularly for theft and vandalism¹⁰. The Atlantic hurricane season runs from June 1 to November 30¹⁴, a period when many seasonal homes sit empty. Ask whether a caretaker's regular visits count as occupancy and whether the policy requires a water shutoff or leak detection.

Before the storm: inventory, documentation and the claims process

A claim is only as strong as the records behind it. The Insurance Information Institute recommends keeping an up-to-date list of personal possessions and storing it somewhere safe away from the home⁵. Standard policies also set special limits on categories such as jewelry and silverware, and a separate schedule or floater is a common way to address them⁵.

• A room-by-room video of the interior, including closets, and of the exterior and roof.
• Appraisals and receipts for art, jewelry, watches and collections, updated periodically.
• A copy of the policy and declarations page stored in the cloud, not only in the house.

Under Fla. Stat. 627.70132, notice of a new or reopened claim must be given to the insurer within 1 year after the date of loss, and notice of a supplemental claim within 18 months; for a hurricane, the date of loss is the date the hurricane made landfall¹¹. Policies also typically require prompt notice and reasonable steps to prevent further damage, so photograph the damage, make temporary repairs and keep every receipt. Rising water and storm surge count as flood, which a standard homeowners policy does not cover¹³.

How to reduce the risk

Wind mitigation is the part of hurricane protection you can document. Florida's Uniform Mitigation Verification Inspection Form (OIR-B1-1802) records the features that help a home resist wind; the current revision took effect April 1, 2026, and the form is valid for up to five years if no material changes are made to the structure and no inaccuracies are found on the form⁹. It must be signed by an inspector authorized under Florida law¹⁵. These are the items it covers^9,17:

Section 627.0629 requires residential rate filings to include actuarially reasonable discounts, credits or other rate differentials for construction techniques shown to reduce windstorm loss, including wind uplift prevention, roof strength, roof covering performance, roof-to-wall strength, wall-to-floor-to-foundation strength, opening protection, and window, door and skylight strength⁸. The amount depends on each insurer's rates and on the home, so there is no single figure. Since October 1, 2023, residential property insurers must describe their hurricane mitigation discounts on their websites⁹.

Older homes often get two other reviews. A four-point inspection looks at the roof, electrical, plumbing, and heating and air conditioning systems; a roof inspection estimates the roof's condition and remaining useful life. Neither replaces the mitigation form, but both help plan repairs before they turn into claims. Remember that Florida's roof-age rule, explained above, depends on the roof's age and remaining useful life³.

The state's My Safe Florida Home program, run by the Florida Department of Financial Services, offers free wind mitigation inspections and grants for eligible homeowners; check its site for eligibility and whether funding is available¹⁶.

A 10-point checklist before each season, which you can work through step by step with our hurricane season checklist:

• Find your current OIR-B1-1802 form and schedule a new inspection if it is more than five years old or the home has changed⁹.
• Ask your agent which mitigation credits appear on your policy and whether any feature is missing from the form⁸.
• Confirm that every opening, including the garage door, has impact protection or shutters you can install in time.
• Test the shutters and their hardware, and label each panel with the opening it belongs to.
• Have the roof inspected, especially after a storm or once it has some years on it.
• Trim trees and store or secure outdoor furniture, planters and anything that can become airborne.
• Service the generator and make sure fuel is stored safely.
• Update the photo and video inventory of the home and its contents, and keep it off site.
• Convert your hurricane deductible into dollars and plan the liquidity to cover it.
• Keep policy numbers, your agent's contact and the claims line where you can reach them without power.
