Wind Mitigation 5-Year Rule: When You Need a New Inspection

Florida Statute 627.711(2) defines wind mitigation inspection validity as up to 5 years from the inspection date. It also includes a 'no material change' condition. The statute itself never defines what 'material change' means. That gap creates real risk for homeowners. Florida insurers fill the definition vacuum with their own underwriting guidelines. They treat any modification that could change a mitigation credit as a triggering material change. Examples include roof replacement, impact-window installation, garage-door swap, and roof-to-wall connection upgrade. Our detailed wind mitigation inspection Florida guide walks through the full inspection process if you're starting from scratch. The key point is that two separate clocks are running at the same time. The first is the 5-year calendar clock. The second is the material-change clock. Either one can invalidate your current OIR-B1-1802 form. A fresh inspection is then required before your carrier restores or upgrades your wind mitigation credits.

Here's a scenario that plays out hundreds of times each year in South Florida: a homeowner gets a wind mitigation inspection in 2020, banks a nice premium discount, and forgets about it. In 2025, the carrier re-underwrites the policy — perhaps after a claim, an insurer switch, or a routine renewal review. The 5-year form has expired. The carrier removes the wind mitigation credits, and the wind portion of the premium snaps back toward the un-mitigated rate. Average annual savings lost when a wind mitigation discount silently expires ranges from $300 to $1,500 per year on a typical South Florida policy, depending on home value, location, and original credit amount. That's up to $7,500 over 5 years, simply for not refreshing a form that costs $75 to $150 to update. Homeowners in high-value corridors like Coral Gables or Weston sit at the higher end of that loss range.

Florida's statute omits a clear definition of 'material change,' so insurers write their own underwriting guidelines. In practice, 5 common modifications consistently trigger the need for a fresh 1802 inspection. This is true across every major Florida carrier. Roof replacement is the biggest trigger. A new roof may qualify for a better roof-cover credit, a better roof-deck-attachment credit, or both. Together, those credits can represent 20 to 30 percent of the total wind mitigation discount. Impact-window installation changes the opening-protection section of the 1802 entirely. It moves a home from 'no protection' or 'panel shutters' to a fully rated impact-glazed opening. That earns the highest opening-protection credit on the form. Garage-door replacement, roof-to-wall connection upgrades such as adding hurricane clips or straps, and any change to glazed openings all appear on the OIR-B1-1802. Each of these would change the inspector's findings. If you've completed any of these upgrades since your last inspection, the wind mitigation 5-year rule may already be moot. The material-change clock ran out the day your permit closed.

The wind mitigation 5-year rule creates a quiet trap for homeowners who upgrade their homes mid-cycle. Consider a homeowner in Pembroke Pines who installed full-home impact windows in year 2 of a 5-year 1802 cycle. Their insurer is still pricing the policy using the old 'no opening protection' credit. That homeowner is leaving money on the table for 3 full years. The only fix is to proactively schedule a re-inspection. The opening-protection credit for a home with fully rated impact-glazed openings is typically the largest single credit on the 1802 form. For lower-slope or hip-roof homes, it is often larger than the roof credits combined. A fresh inspection at $75 to $150 can pay back its cost in the first month of the revised premium.

A valid OIR-B1-1802 form is generally portable between Florida insurers. The form belongs to the home, not the policy. However, the receiving carrier is not required to accept the existing form without scrutiny. Many insurers, including Citizens Property Insurance, can request a fresh inspection during underwriting. If your form is 3 or more years old at the time of the switch, expect at least 1 in 3 new carriers to require a fresh 1802. That fresh 1802 must be submitted before the full discount applies. The Citizens Insurance wind mitigation discount page covers how Florida's insurer of last resort scores the credits. It applies whether you're switching to or from Citizens. Homeowners in West Palm Beach, Fort Lauderdale, and Miami switching carriers mid-cycle should check the inspection date before binding the new policy. A surprise re-inspection request can delay your discount by 30 to 60 days if you're not prepared. You can verify your inspector's license through the Florida DBPR contractor lookup before hiring.

The OIR-B1-1802 form explained page covers every credit category in detail. The wind mitigation 5-year rule applies equally across all 8 sections of the form. The sections include roof covering, roof deck attachment, and roof-to-wall connection. They also include roof shape, opening protection, and secondary water resistance. Each section is individually scored. A material change to any one section resets the accuracy of the entire form for that credit category. The Florida Building Code governs the minimum standards for impact-rated products used in these upgrades. Products your contractor installs must be documented with a Notice of Acceptance (NOA) or Product Approval number. The wind mitigation inspector must be able to confirm that documentation. Impact windows installed without proper permits or code-compliant documentation will not earn the opening-protection credit on a fresh 1802. This is true regardless of the product's physical rating.
