Why this topic matters to a Canadian buyer
In most of Canada, homeowner insurance prices wind risk implicitly, as one peril among many in an "all risks" or named-perils homeowner policy. A Quebec buyer, for example, is used to a single annual premium covering wind, fire, water, theft, and liability without a granular discount framework attached to specific construction features.
Florida is structured differently. Wind exposure is treated as its own pricing layer, and the legislature has codified a discount mechanism that requires insurers to recognize specific construction features. Section 627.0629(1) of the Florida Statutes mandates that residential property insurers provide rate differentials, credits, or deductible reductions for properties on which fixtures or construction techniques demonstrated to reduce windstorm losses have been installed or implemented.
The practical consequence for a Canadian buyer is direct. A Florida property without a current wind mitigation form is, by default, priced as if it had no qualifying mitigation features, even when the home was built to FBC 2001 or later, has a hip roof, and has impact-resistant glass. The credits apply only when documented on the form. A document that costs 100 to 200 USD and takes one hour produces five years of credits. The return on that hour is, mechanically, the largest single-document financial decision in the closing process.
This article applies to Canadian buyers acquiring a single-family home, a townhouse insured under an HO-3-style policy, or a small multifamily property insured per unit. It applies in a different and more limited way to Canadian buyers acquiring a condominium unit, where the master policy carries the structural exposure. The condo case is treated separately below.
What the inspection is and what the form documents
The wind mitigation inspection is a visual and documentary survey of the construction features that determine how a home is expected to perform in a hurricane. It is not a structural soundness test, it is not a code-compliance audit, and it does not overlap meaningfully with the general home inspection or with the four-point inspection used to underwrite the policy itself. Its sole purpose is to determine which premium credits apply.
The inspector arrives with the OIR-B1-1802 form, examines the roof from a ladder and the attic from inside, photographs the eight to twelve features documented on the form, and produces a signed report submitted to the homeowner. The homeowner (or the insurance broker) then forwards the report to the insurer, which applies the credits at the next renewal or, in some cases, mid-term with a prorated refund.
The form was created by the Office of Insurance Regulation in 2003 and has been updated periodically. The most recent revision took effect on April 1, 2026, following the 2024 Residential Wind-Loss Mitigation Study completed by Applied Research Associates. The new version refines the construction features and credit categories that qualify for discounts. Inspections performed before April 1, 2026 remain valid until their five-year horizon expires, but Canadian buyers ordering an inspection in 2026 or later should confirm that the inspector is using the current revision of the form.
The features the form documents, explained
The form structures the inspection around a set of construction features. Each feature is observed, photographed, and recorded with the attribute level that applies. The features below are the categories that drive the bulk of the credits. Specific question numbering and credit weighting are subject to the April 2026 revision; the underlying physics has not changed.
Building code era. The single largest credit on most homes is whether the structure was built under the FBC 2001 (effective March 1, 2002) or under the South Florida Building Code 1994 (in Miami-Dade and Broward, the HVHZ counties). Post-Andrew code reform was driven by the observation that wind damage was correlated less with wind speed than with construction quality. FEMA's mitigation-assessment teams after Hurricane Ian (2022) reported that homes built to the FBC 2001 sustained materially less wind-related structural damage than equivalent homes built before. Insurers price this directly: a permit application date after March 1, 2002 (or after September 1, 1994 for HVHZ structures) produces a substantial credit; an earlier date produces none.
Roof covering. The form records whether the roof was installed under a Florida product approval that meets the FBC standards in force at the time. A re-roof permitted after March 1, 2002 generally qualifies even on an older house. The credit recognizes that modern roof coverings (asphalt shingles, metal panels, tile systems) are tested and installed to wind-uplift standards that older coverings were not.
Roof deck attachment. The form measures how the plywood or OSB deck is fastened to the roof framing. Eight-penny common nails (8d) spaced at six inches in the field, or stronger fasteners, qualify. Older homes with staples or with widely spaced nails do not.
Roof-to-wall connection. The form distinguishes four levels: toe nails (the weakest, used in older construction), clips, single wraps, and double wraps. The wrap categories use metal hurricane straps that wrap from the rafter or truss to the wall top plate. The credit difference between a toe-nailed connection and a double-wrap connection is among the largest on the form, because this is the joint that fails first when uplift exceeds the design load.
Roof geometry. A hip roof (pitched on all four sides) performs materially better in high winds than a gable roof (pitched on two sides, with vertical end walls that act as sails). The form records whether at least 90 percent of the roof perimeter is hip. This is one of the few features that cannot be retrofitted economically; it is locked at construction.
Secondary water resistance. This is a self-adhering membrane installed under the roof covering, designed to prevent water intrusion if the primary covering is torn off in a hurricane. It does not prevent wind damage; it prevents the rainwater that follows. The credit is modest individually but combines well with strong roof and opening features.
Opening protection. Windows, glazed doors, glass-block walls, skylights, and garage doors are evaluated for their ability to resist debris impact at the wind speed required for the property's location. The form distinguishes hurricane-rated impact glass (factory-tested), code-approved hurricane shutters (deployable), and unprotected openings. The credit difference between an unprotected home and a fully impact-protected home is, on most modern coastal properties, the second-largest credit on the form after the building-code-era credit.
A modern home (post-2002 permit, hip roof, double wraps, secondary water resistance, impact-glass openings) typically captures most of the available credits. An older home (pre-1994 permit, gable roof, toe nails, no opening protection) typically captures few or none. Most Canadian buyers will be looking at properties between those endpoints, where the marginal value of the inspection is high precisely because the outcome is uncertain until the inspector documents what is there.
How the savings actually work: a worked example
Florida property-insurance premiums are built from several sub-rates. The two largest are usually the windstorm rate (hurricane wind exposure) and the all-other-perils rate (fire, theft, water, liability). Wind mitigation credits apply only to the windstorm rate. The total-premium impact depends on what share of the total premium the windstorm rate represents.
A worked example, denominated in USD on annual premium:
| Component | Coastal home, no inspection | Coastal home, fully credited |
|---|---|---|
| Total annual premium (USD) | 6,000 | (computed below) |
| Windstorm portion (assumed 60 percent) | 3,600 | 3,600 minus credit |
| All-other-perils portion | 2,400 | 2,400 |
| Wind credit (35 percent of windstorm portion) | 0 | -1,260 |
| Total annual premium after credit | 6,000 | 4,740 |
| Saving over 5-year form validity | n/a | 6,300 |
On the assumptions above, the inspection cost (typical range 100 to 200 USD) is recovered in the first year by a factor of six to twelve. A non-coastal home with a smaller windstorm portion produces a smaller absolute saving but the same proportional dynamic. The numbers are filing-specific and should be confirmed with the insurance broker on the property's actual rate sheet.
Who is allowed to sign the form
The statutory list is closed and the qualifications matter. The five categories of authorized inspector are: a Florida-licensed home inspector under section 468.8314 who has completed at least three hours of CILB-approved hurricane mitigation training and passed a proficiency exam; a building code inspector certified under section 468.607; a general, building, or residential contractor licensed under section 489.111; a Florida professional engineer licensed under section 471.015; and a Florida registered architect licensed under section 481.213. The statute also permits any other individual or entity that the insurer recognizes as qualified, but in practice insurers default to the statutory list.
The signing inspector must personally perform the inspection. Engineers and contractors may delegate to a direct employee; home inspectors and code inspectors may not. License status must be verified on myfloridalicense.com before payment. Use of an unlicensed signer is the most common reason an insurer refuses to apply credits.
How Florida differs from a Quebec or Canadian baseline
The wind mitigation framework is unusual when compared to Canadian property-insurance practice. The table below sets out the structural differences, segregating jurisdictional levels explicitly.
| Dimension | Sale or purchase, Canadian side (Quebec reference) | Acquisition, Florida side |
|---|---|---|
| Statutory framework for wind discounts | None at federal CA or provincial QC level. Insurers price wind as one peril within an aggregate property-insurance rate. | State of Florida: §627.0629 (mandates mitigation discounts) and §627.711 (uniform form, inspector categories, validity). |
| Standardized inspection form | None. Insurers may request roof-age proof or hardening-feature evidence on a case-by-case basis. | OIR-B1-1802 (April 2026 revision), accepted by every admitted Florida insurer. |
| Credit framework | Carrier-specific. Some Canadian insurers credit roof age, water shut-off devices, or alarm systems, but no uniform statewide framework exists. | Statewide credit categories tied to roof, walls, openings, and code era. Same structure across all carriers. |
| Validity of supporting documentation | Carrier-specific. Roof-age proof typically refreshed at each renewal. | Five years from the inspection date, structure unchanged. |
| Regulator | Provincial QC: Autorité des marchés financiers (AMF). | State of Florida: Office of Insurance Regulation (OIR), with rule 69O-170.0155 governing the form. |
| Practical implication for the buyer | Property insurance is one item on the closing budget; no separate inspection is ordered to optimize it. | The wind mitigation inspection is a distinct line item, ordered before binding insurance and treated as a financial document. |

Strategy: ordering the inspection before or after closing
The strategy decision is small but consequential. There are two reasonable timings.
The first option is to order the inspection during the inspection contingency period, alongside the general home inspection and the four-point inspection. The combined three-inspection visit typically costs 400 to 700 USD in central and north Florida and 500 to 900 USD in South Florida, with the wind mitigation portion at the lower end of that range. The advantage is informational: the insurance broker can quote on the basis of the actual mitigation features, not assumed ones, and the buyer can compare insurers on a real basis before binding. This timing is standard practice.
The second option is to bind insurance without a current wind mitigation form, close the transaction, and order the inspection within the first weeks of ownership. The credits apply at the next renewal or, with some carriers, mid-term with a prorated refund. This timing is sometimes preferred when a closing is rushed, when the buyer is acquiring an older home where the credit outcome is uncertain, or when the property already has a wind mitigation form on file from a prior owner that is still within its five-year validity (insurers will accept a prior-owner form in most cases, but the buyer should confirm).
Special case: Canadian buyer purchasing a Florida condominium
A condominium unit owner does not insure the building exterior. The condominium association carries a master policy on the structure, including the roof, the exterior walls, the openings as defined in the declaration of condominium, and the common elements. The unit owner carries an HO-6 policy that covers the interior finishes, the contents, the personal liability, and limited loss-assessment exposure.
Wind mitigation credits on the master policy are an association matter, not a unit-owner matter. The association may order an HVHZ-conforming inspection for a low-rise building (one to three stories) using OIR-B1-1802, or a different form (MIT-BT) for a building of four or more stories, and apply the resulting credit to the master-policy premium. The unit owner pays this premium indirectly through the monthly assessment.
On the HO-6 unit-owner policy, wind mitigation credits exist but are materially smaller, because the dwelling coverage is small (interior finishes only, not the structure). Some insurers offer no wind mitigation credit at all on HO-6 policies; others offer a modest credit on the loss-assessment coverage. A Canadian condo buyer should confirm with the broker whether the master policy is up to date on its wind mitigation form (an old or absent form on the master policy will keep the building's premium higher than it needs to be, and that cost flows through the assessment), and whether the HO-6 quote already reflects any available unit-level credit.
For Canadian buyers, the practical implication is that the wind mitigation inspection is a high-value document on a single-family home and a low-to-moderate-value document on a condo unit. The Florida-condo question that more often dominates the closing analysis is the master policy's hurricane deductible (typically 2 to 5 percent of the building's insured value) and the loss-assessment exposure that flows from it. That topic is treated in a dedicated guide in Chapter 02.
Common mistakes Canadian buyers make
The mistakes below recur often enough to be worth listing explicitly.
- Treating the wind mitigation inspection as overlapping with the four-point inspection. They are not. The four-point inspection (roof, electrical, plumbing, HVAC) is what an insurer requires to underwrite a policy on a home older than a threshold (commonly 30 or 40 years). The wind mitigation inspection determines what credits apply to that policy. A bound policy without a wind mitigation form is a fully priced policy with no mitigation credits.
- Ordering the inspection from the general home inspector without confirming statutory authorization. Not every Florida home inspector has the three-hour CILB-approved hurricane mitigation training required by section 627.711(2)(a)(1). A form signed by an unauthorized inspector will be refused by the insurer.
- Assuming a recent re-roof produces the same credit as a post-2002 build. A re-roof permitted after March 1, 2002 qualifies for the roof-covering credit, but it does not change the building-code-era classification, which is locked at the original permit date.
- Skipping the inspection on an older home on the assumption that no credits will apply. Many pre-2002 homes have had selective hardening (re-roof, hurricane shutters, impact-glass replacement) that produces meaningful partial credits. The inspection cost is recovered in months even at modest credit levels.
- Submitting a form to the insurer without keeping a clean PDF copy. The form is valid for five years and will be needed at every renewal until the next inspection. Buyers who lose the file pay for a second inspection unnecessarily.
- Confusing the wind mitigation credit with the total premium. The credit applies to the windstorm portion only. Quoted savings of "30 to 60 percent" sometimes refer to the windstorm portion in isolation; the total-premium impact is smaller, though still substantial. Brokers should be asked to itemize the wind portion before and after the credit.
- Letting the form expire silently. At month 60 the form is no longer accepted. The renewal will reprice without credits unless a fresh inspection is on file. Calendar a reminder at month 54.
Action checklist
The sequence below covers a typical Canadian acquisition.
- Within 48 hours of the offer being accepted, ask the listing broker whether a current wind mitigation form is on file from the seller or a prior owner. If yes, request a copy and check the inspection date.
- If no current form exists, ask the buyer's insurance broker to quote on an "as-is" basis (no mitigation credits assumed) and on a "best-case" basis (assumed credits).
- Schedule the wind mitigation inspection inside the inspection contingency window, ideally on the same visit as the general home inspection and the four-point inspection.
- Verify the inspector's license on myfloridalicense.com and confirm in writing that the inspector is using the April 2026 revision of OIR-B1-1802.
- On receipt of the signed form, save a clean PDF copy in a folder dedicated to the property's permanent records.
- Forward the form to the insurance broker before binding the policy. Ask for an itemized quote showing the windstorm rate before and after the mitigation credit.
- Calendar a reminder at month 54 of the form's validity to schedule the next inspection.
Frequently asked questions
Is the wind mitigation inspection required by Florida law? No. The inspection is voluntary. The credits exist only when the form is on file with the insurer. Without the form, the property is rated as if it had no qualifying mitigation features.
Does the form transfer to a new owner at closing? Yes, in practice. A form signed by a qualified inspector documents the property's features, not the owner. Most insurers will accept a prior-owner form for the new owner, provided it remains within its five-year validity and the property has not been altered. The new owner's broker should confirm with the new carrier in writing.
Can the inspection be performed without the buyer or owner present? Yes for the exterior and roof inspection. The interior portion (attic access for roof deck attachment and roof-to-wall connection) requires that the inspector enter the home, so a key, lockbox, or scheduled access is needed.
What happens if the home was renovated after the form was issued? Material changes (re-roof, replacement of openings, addition that alters the roof geometry) invalidate the form to the extent the changes affect documented features. A fresh inspection captures the updated state and resets the five-year clock.
Does the inspection produce a "pass" or "fail"? No. The form is descriptive, not prescriptive. It documents what is there. A home with no qualifying features receives a valid form that produces no credit.
Will the inspection identify defects that an insurer will require repaired? Not directly. The wind mitigation form documents construction features for the discount calculation. Defects that affect insurability (a roof past its useful life, electrical issues, plumbing leaks) are surfaced by the four-point inspection or the general home inspection. A failed four-point inspection is what blocks insurance binding, not the wind mitigation form.
Is the inspection useful in north Florida or central Florida, where hurricane risk is lower? Yes, though the absolute saving is smaller. The windstorm portion of the premium is smaller in non-coastal areas, so the same percentage credit produces fewer dollars. The inspection still recovers its cost easily within five years.
Is the inspection useful for a Canadian buyer of a condominium unit? Limited. See the condominium section above. The high-value inspection on a condo is the association's master-policy inspection, not the unit-owner's HO-6 inspection.
Logical next step
Once the wind mitigation inspection is in hand, the next step in the inspection-and-due-diligence sequence is to verify that no open permits remain on the property's permit history. An open permit attaches to the property and transfers to the new owner, with potential remediation cost.
