Wind Mitigation Inspection Florida 2026: Insurance Guide

    If you've installed impact windows — or plan to — a wind mitigation inspection is the step that unlocks your insurance discount. Without it, your insurer applies zero credit for your windows, even with full Miami-Dade NOA certification installed and permitted. This guide covers everything: the form, the categories, the savings, and the process.

    What Is a Wind Mitigation Inspection?

    A wind mitigation inspection is a formal assessment of your home's structural features that affect its ability to withstand hurricane-force winds. A licensed inspector evaluates your home and produces the state-standardized OIR-B1-1802 Wind Mitigation Report form — the document you submit to your insurance company to unlock premium discounts.

    Florida law (FS 627.0629) requires every residential property insurer in Florida to offer premium discounts based on wind mitigation features. The wind mitigation inspection is how you prove your home qualifies.

    The OIR-B1-1802 Form covers 6 areas:

    Roof covering, roof deck attachment, roof-to-wall connection, roof shape, opening protection (where impact windows matter), and secondary water resistance. Impact windows affect Opening Protection — often one of the most significant credits on the form, though the amount varies by insurer.

    The 6 Rating Areas: What the Inspector Evaluates

    1. Roof Covering

    What inspector checks:The material that covers your roof deck — shingles, tile, metal, foam.
    Discount potential:FBC-compliant roof covering (2001 or later code): significant discount
    Impact windows:Impact windows don't affect this — but a newer roof + impact windows = maximum total discount

    2. Roof Deck Attachment

    What inspector checks:How the plywood or OSB roof deck is nailed to the roof joists.
    Discount potential:8d nails at 6-inch spacing: highest category. Staples: no credit.
    Impact windows:Not affected by window installation

    3. Roof-to-Wall Connection

    What inspector checks:How the roof structure connects to the walls — toe-nails, clips, single wraps, double wraps.
    Discount potential:Double wraps or clips: best category, largest discount contribution
    Impact windows:Not affected by window installation

    4. Roof Shape

    What inspector checks:The geometry of your roof — hip, gable, flat, or complex.
    Discount potential:Hip roofs (all four sides sloping): best discount. Gable ends: lesser discount.
    Impact windows:Not affected by window installation

    5. Opening Protection ← Impact Windows

    What inspector checks:Whether all windows, doors, skylights, and garage doors are protected.
    Discount potential:Category A (all openings, FBC-compliant impact products): the largest opening-protection credit your insurer offers (amount varies by insurer)
    Impact windows:THIS is where impact windows make their full contribution. Without verified opening protection, there is no credit here.

    6. Secondary Water Resistance

    What inspector checks:Self-adhering modified bitumen underlayment beneath the roof covering.
    Discount potential:SWR present: meaningful additional credit
    Impact windows:Not affected by window installation

    Opening Protection Categories (OIR-B1-1802)

    The Opening Protection section of the wind mitigation form classifies the home by its weakest protected opening. Which category you fall into determines your opening-protection credit for this section:

    CategoryDescriptionTypical DiscountImpact Windows
    Category AAll glazed openings protected by products verified to the large-missile (9-lb) impact standardsLargest opening-protection credit (varies by insurer)Impact windows + NOA/FPA = qualifies
    Category BAll glazed openings protected by products verified to a lower large-missile impact level (4 to 8 lb)Partial opening-protection credit (varies by insurer)Some older or lighter-rated products fall here
    Category COpenings protected by wood structural panels (plywood/OSB) meeting the Florida Building CodePartial credit (varies by insurer)Panels, not impact windows
    Category NProtection present but not verified to A, B or C (e.g., no product approval documentation)Little or no credit (varies by insurer)Keep NOA/FPA paperwork to avoid this
    Category X / NoneOne or more openings not protected — standard glass, no shuttersNo opening-protection creditMaximum insurance exposure

    Category A is achievable when ALL glazed openings (every window, glass door and skylight, with the garage door documented too) are protected by products verified to the large-missile impact standards. If any opening is unprotected, the home falls to Category X.

    How to Find Out What the Discount Is Worth to You

    Florida law requires insurers to offer wind-mitigation discounts, and they apply only to the hurricane-wind portion of your premium — not the whole policy. Each carrier sets its own credits in its filed rates, so the amount depends on your insurer and your home (roof shape, roof-to-wall attachment, opening protection and the other rating areas on the form).

    • Ask your agent for a quote with and without the opening-protection credit.
    • Submit the completed OIR-B1-1802 form after the final inspection closes your permit.
    • Check your declarations page at renewal to confirm the credit was applied.

    What You Must Have to Qualify for Category A

    • All openings protected

      Every window, every door, every skylight, and your garage door must be impact-rated or approved-shutter-protected. Even one unprotected opening drops you out of Category A.

    • Current FBC-compliant product approval

      Products must have a current Miami-Dade NOA or Florida Product Approval number. Expired approvals don't count. Vieser Construction installs PGT, ESW, and Mr. Glass — all carry current NOA.

    • Professional installation

      Products must be installed to the manufacturer's approved method and pass final inspection. DIY installation, even with NOA-certified products, does not qualify.

    • Permitted and inspected

      A building permit must have been pulled and a final inspection passed. Unpermitted work does not qualify for wind mitigation credit and can cause insurance claim denials.

    Cost, Timing and Credit Range at a Glance

    ItemTypical rangeNotes
    Inspection cost$75 to $150 (some $175)Varies by inspector and property size

    Insurer processingAbout 2 to 3 weeksVaries by carrier
    Wind-mitigation creditVaries by insurerApplies to the hurricane-wind portion; depends on carrier and all six rating areas

    Inspection and processing figures are typical market ranges, not guarantees. Your carrier's filed rates set your actual credit.

    The credits exist because of Florida Statute 627.0629, which requires residential property insurers to offer discounts for wind-resistant features and has been in effect since 2002. Submit your completed form before your renewal date so the credit is included in your next premium, and ask your agent to confirm in writing when it is applied.

    Checklist: After Installation, Inspection, Then Insurer

    1. Confirm the permit passed final inspection and is closed.
    2. Collect product approval numbers (NOA or Florida Product Approval) and permit records.
    3. Verify every window, door, skylight, and garage door is protected.
    4. Hire a licensed inspector and book the visit after permit closure.
    5. Receive the completed OIR-B1-1802 form with photos.
    6. Send the form to your agent or carrier before your renewal date and request a re-rating.
    7. Follow up until the credit appears, and keep the report on file.

    Step-by-Step: From Installation to Insurance Discount

    1

    Install impact windows

    All openings — windows, doors, garage door — must be protected for maximum credit. Vieser Construction handles full installation with permitting.

    2

    Wait for permit to close

    The county must perform a final building inspection and close the permit. This confirms code-compliant installation.

    3

    Schedule wind mitigation inspector

    Hire a licensed inspector (home inspector, contractor, or engineer). Schedule after permit closure — not before.

    4

    Inspector visits and documents

    45–90 minute visit. Inspector photographs all windows, checks product approval numbers, reviews permit documents.

    5

    Receive OIR-B1-1802 report

    You receive the completed form — typically 3–5 business days after inspection. Digital delivery common.

    6

    Submit to insurance agent

    Send the OIR-B1-1802 to your agent and request a premium re-rating. Do NOT wait for the next renewal.

    7

    Discount applied

    Carrier processes in about 2–3 weeks. Mid-term credit issued or renewal premium reduced. Confirm with your agent.

    Common mistake: Scheduling the wind mitigation inspection before the permit closes. The inspector needs to see closed permit documentation. Schedule after final inspection passes — not immediately after installation.

    Citizens Insurance Wind Mitigation Requirements

    Citizens Property Insurance (Florida's insurer of last resort, covering ~1 million South Florida homeowners) has specific wind mitigation rules:

    • Citizens accepts OIR-B1-1802 reports from all qualifying inspectors
    • Citizens requires an updated report when a covered modification occurs (new roof, new windows)
    • Citizens may conduct their own verification inspection on claims
    • For Citizens, Category A opening protection earns the largest opening-protection credit in its filed rates — ask your agent for the exact amount
    • Citizens sends annual statements showing current wind mitigation credits — verify these match your report

    Verify any inspector's license at myfloridalicense.com before hiring. Do not use unlicensed inspectors — reports from unlicensed parties will be rejected by your insurer.

    Frequently Asked Questions

    How much does a wind mitigation inspection cost in Florida?

    A wind mitigation inspection typically costs $75–$175 in South Florida. Some contractors bundle it with installation packages. It documents the wind-mitigation credits Florida insurers must offer on the hurricane-wind portion of your premium; the amount depends on your insurer and your home.

    Does a wind mitigation report expire in Florida?

    Wind mitigation reports (OIR-B1-1802) do not have a statutory expiration date, but most Florida insurers require an updated report if the property has been modified (new roof, new windows) or if the existing report is more than 5 years old. Citizens Insurance specifically requires updates after any modification that could affect the rating.

    Who can perform a wind mitigation inspection in Florida?

    Florida law allows wind mitigation inspections to be performed by: licensed home inspectors, general contractors, building contractors, residential contractors, professional engineers, and architects. The inspector must be licensed under the applicable Florida statutes. Verify credentials at myfloridalicense.com before hiring.

    What is opening protection category A on the OIR-B1-1802 form?

    Category A (formerly 'All openings protected - Miami-Dade NOA or FBC approved') is the highest opening protection rating on the Florida wind mitigation form. It requires all openings (windows, doors, skylights, garage doors) to be protected by products meeting the Florida Building Code standard for the applicable wind zone. Impact windows with Miami-Dade NOA qualify for Category A in HVHZ locations.

    Will my insurance automatically update after I submit the wind mitigation report?

    Not automatically — you must contact your insurance agent and request a premium re-rating based on the new report. Most carriers process this within about 2–3 weeks. Some apply the discount mid-term (you'll receive a credit); others apply it at your next renewal date. Always follow up with your agent rather than assuming the update happened.

    When should I submit the wind mitigation form to my insurer?

    Submit it as soon as you have the completed OIR-B1-1802, and ideally before your policy renewal date so the credit is reflected in your next premium. A typical processing range is about 2 to 3 weeks, but it varies by carrier. Ask your agent to confirm in writing when the re-rating is applied.

    Which Florida law requires insurers to give wind mitigation discounts?

    Florida Statute 627.0629 requires residential property insurers to offer discounts, credits, or rate differentials for wind-resistant features, including opening protection. The percentages themselves come from each carrier's filed rates, so confirm your specific credit with your insurer or agent.

    Do I need a wind mitigation inspection for every insurance policy renewal?

    No. Once a wind mitigation report is on file with your insurer, the discount applies every renewal until the insurer requires an update (usually after 5 years or property modifications). You do not need a new inspection annually.
