Do Hurricane Shutters Lower Home Insurance Costs in Florida?

Yes, hurricane shutters can lower your home insurance in Florida, through a wind mitigation credit. The shutters have to be approved and documented on a wind mitigation inspection, and the best ratings need every opening, not just the windows, to be protected or rated. Florida law requires insurers to build these credits into their rates but doesn't set a dollar amount, so what you save depends on your insurer and the rest of your house.

What has to line up for a credit

1. The shutters are tested and approved. Each product needs a Florida product approval or a Miami-Dade Notice of Acceptance, and the top opening protection levels are defined by large-missile impact ratings. A Miami TV news consumer report notes that a discount may not be given if products don't meet the current code.
2. Every opening is protected or rated, including doors, skylights and glass block (see below).
3. An inspector documents it on the state's Uniform Mitigation Verification Inspection Form (OIR-B1-1802), usually called the wind mitigation form.
4. Your insurer applies its credit. The amount comes from the insurer's own rate filing, not from the form.

Miss any one and the shutters may protect your house without changing your premium much.

What Florida law requires of insurers

Section 627.0629 of the Florida Statutes requires residential property insurance rate filings to include actuarially reasonable discounts, credits or other rate differences, or reductions in deductibles, for homes with features shown to reduce windstorm losses. The listed features include opening protection and the strength of windows, doors and skylights. In practice:

• The credit applies to wind coverage. The Office of Insurance Regulation's wind mitigation resources page publishes the credit forms, including OIR-B1-1699 for single-family homes, and shows a range of wind premium credits for existing homes. When we checked, those forms were marked as having updates pending, so we don't quote percentages here.
• It may not be a premium discount. The law also allows a lower deductible, so ask which one your insurer uses.
• Your insurer has to publish its discounts. The statute requires each insurer to provide information about its hurricane mitigation discounts on its website.
• Credit values get reviewed. The law required the Office of Insurance Regulation to re-evaluate the qualifying features and their discount values by January 1, 2025, and every five years after that, so today's credit isn't fixed forever.

How the inspection form rates shutters

Tested performance, not product type

The form's opening protection levels are described in terms of testing, mainly large-missile impact, rather than whether the glass is impact-rated or covered by a shutter, so both can qualify. We haven't found an official statement that shutters and impact glass always earn the same credit, so ask your insurer. Our guide to impact windows vs. hurricane shutters compares the two.

The least-protected opening decides the level

My Safe Florida Home's explanation of the form, which may describe the earlier 2012 version, defines the top three levels by every opening on the house. Here's how they apply to a shuttered home:

• A.1: every opening, including the solid entry and garage doors, is rated for large-missile impact. With shutters, that means the doors also need impact ratings, either as impact-rated doors or, if the shutter's approval allows it, covered by a rated shutter. Ask an inspector how a shutter over a solid door would be rated.
• A.2: rated shutters cover all the glass, including door glass and sidelights, and the solid entry and garage doors are verified as rated for wind pressure.
• A.3: rated shutters cover all the glass, but the solid doors can't be verified.

Because each level needs every opening to meet it, the least-protected opening effectively sets the level. One bare sidelight or an old skylight can keep all the glass out of the top levels, and an undocumented garage door can drop a fully shuttered house from A.2 to A.3. Mixing shutter types, such as accordions upstairs and panels downstairs, shouldn't matter as long as each one is approved and rated, but confirm with your inspector. My Safe Florida Home advises asking your insurer whether it needs A.1 or A.2 for its discounts, because carriers differ.

The 2026 form

A revised form, OIR-B1-1802 (Rev. 04/26), took effect April 1, 2026, and inspections on or after that date must use it. Citizens Property Insurance lists opening protection among the features updated on it, but the summaries we found don't spell out the new categories. Before you buy, ask a wind mitigation inspector how the current form would rate your plan.

Every opening counts

Florida's Hurricane Retrofit Guide ties the insurance discount to protecting all openings: windows, entry doors, sliding glass doors, skylights and garage doors. Shuttered homes most often fall short at the openings people forget.

Garage doors deserve a closer look. A 2021 garage door industry technical sheet, citing the state's single-family credit form (OIR-B1-1699), says the form's top "Hurricane" tier needs glazed and non-glazed openings alike to meet the highest impact standard, a 9-lb missile test, with both missile impact and cyclic pressure tested. Lower levels are grouped as "Basic." Florida Building Commission course material adds that where the code requires impact protection, glass in a garage door must meet an approved impact standard or ANSI/DASMA 115.

For the front door, the usual choices are an impact-rated door or a shutter over it, if the shutter's approval allows that. Our impact front door cost guide covers the door option. Ask installers to price every opening, including the doors and skylights, even if you plan to phase the work, so you can see what the full rating would cost.

What counts as proof

An inspector can only credit what they can verify. The A.3 level shows how missing paperwork alone can cost you a level. Keep these together:

• The product approval for each shutter type. That's the Florida approval (FL) number or Miami-Dade NOA, plus the approval document. You can look up any FL number on the Florida Building Commission's product approval search. Approval documents list details such as the large-missile impact level, the wind zone and whether the product can be used in the High-Velocity Hurricane Zone (Miami-Dade and Broward).
• The permit and the final inspection. In unincorporated Brevard, the county's doors, windows and shutters permit asks for the product approval, the manufacturer's installation instructions and a floor plan showing where each product goes. West Melbourne asks for a drawing of the numbered openings on window and door permits. Keep a copy of that plan: it's the opening-by-opening record an inspector needs.
• A contract or invoice that lists every opening by location and size, with the product and approval number used on each.
• Approval paperwork for the entry doors and garage door, since these decide between the top levels.
• Photos of each opening with its shutter closed, and of stored panels labeled by opening. No rule we found requires them, but they help if a question comes up later.

Shutters installed without a permit, or panels bought years ago with no paperwork, are harder to document. If you're not sure what you have, an inspector can tell you what's missing before you spend money replacing anything.

Timing the wind mitigation inspection

Book the inspection after the shutter permit passes its final inspection, because a report done before the shutters went on won't show them. Citizens says it will keep accepting a report on the older form (Rev. 01/12) if it was completed within five years before April 1, 2026 and the structure hasn't changed. Other insurers set their own rules, so ask yours.

If you have storm panels, have the panels, hardware and approval documents ready, and ask the inspector before the visit what they need to see. When the report arrives, read the opening protection answer before you send it to your insurer. If the rating is lower than you expected, ask the inspector which opening set it and what would change it.

Our wind mitigation inspection guide explains who can do the inspection, the roof features it records alongside your openings, and the state's My Safe Florida Home grants.

Questions to ask your insurer before you buy

Start with your insurer's website, which must have information about its mitigation discounts. Then ask your agent:

1. Which opening protection level earns a credit with you, A.1 or A.2?
2. With my current roof features, how would my wind premium change at that level? Credits are figured for the whole house, so the answer depends on more than your openings.
3. Is the credit a premium discount or a lower deductible?
4. Which versions of the inspection form do you accept, and how old can a report be?
5. Do you need anything besides the inspection form?

Get the answers in writing if you can. We don't publish savings estimates, because the real number depends on your insurer's filing, your policy and your home's other features.

Is it worth adding shutters for the discount?

Treat the credit as a bonus, not the main reason. Approved shutters are built to keep wind-borne debris from breaking your windows and doors, though no product guarantees a home comes through a hurricane undamaged. To judge the money side, compare the one-time cost with the yearly change your agent quotes, and think about how long you'll own the house.

Our Florida planning estimates, which aren't quotes, run per square foot of opening covered from about $7–$15 for storm panels and $9–$15 for hurricane fabric screens to $15–$35 for accordion shutters, $25–$60 for manual roll-downs and $50–$120 for motorized roll-downs. The hurricane shutter cost guide has example budgets, and impact windows vs. hurricane screens covers fabric and screen options, which are rated by their tested performance like any shutter.

• A credit doesn't close the shutters. The report records what's installed, not whether anyone will put it up. If you're away during hurricane season, see the advice for seasonal owners in impact windows vs. hurricane shutters.
• Grants may help. My Safe Florida Home's eligible improvements guide lists the opening protection upgrades the program covers. Check current funding and eligibility before you plan around it.

On the Space Coast

• Who issues the permit. In unincorporated Brevard, including Viera, Suntree and Merritt Island, shutters go through the county's doors, windows and shutters permit. Inside city or town limits, such as Melbourne, Palm Bay, West Melbourne or the beach towns, the city or town handles it; see building permits in Brevard County. Don't assume shutter work qualifies for Florida's under-$7,500 permit exemption; read the $7,500 permit exemption first. The final inspection is also part of your paper trail.
• Barrier island and waterfront lots. Besides an impact rating, each shutter must be approved for the design wind pressure at its opening. Brevard County's wind speed maps give an address's design wind speed, and exposure can raise pressures near open water. Ask your building department or installer which design pressure your openings need.
• Salt air. A seized accordion track or a missing panel bolt won't protect anything, whatever the report says. See salt-air corrosion on Space Coast homes.
• HOAs. Florida HOAs must adopt hurricane protection specifications and can't deny a conforming application, but they can set colors and styles. See HOA approval in Florida.

Common mistakes

• Covering the windows and forgetting the rest. Sidelights, the garage door, a skylight or one small window can hold the rating down.
• Buying "hurricane" shutters without checking the approval. Decorative shutters and untested coverings won't count toward the impact-rated levels.
• Losing the paperwork. Without approval numbers and permit records, an inspector may not be able to verify what you have.
• Not getting a new inspection. Your insurer doesn't know about the shutters until a new report reaches it.
• Buying before asking the insurer. Find out whether it needs A.1 or A.2 before you set the scope of the job.
• Expecting a set dollar amount. Credits vary by insurer and depend on the whole house.

Next steps

1. Check your insurer's website for its mitigation discounts, and ask your agent which opening protection level it credits.
2. If you have a recent wind mitigation report, read its opening protection section to see where you stand.
3. List every opening: windows, sliders, entry doors and their glass, the garage door, skylights and glass block.
4. Get itemized quotes that cover every opening, with product approval numbers and design pressures. Check each contractor's license with our contractor checklist, and see why contractor quotes differ.
5. Confirm who issues your permit, and make sure the shutters pass final inspection.
6. Gather the approvals, permit records and photos, book a wind mitigation inspection, and send the report to your insurer.
