Most Palm Beach County homeowners have a wind mitigation inspection report on file with their insurer — and most of them have never read it. This is a costly oversight. The OIR-B1-1802 form is a seven-section document that determines what fraction of your wind insurance premium you pay, and each section represents a specific building feature that your insurer has already assigned a discount value to. Knowing what each section evaluates, what your current ratings are, and what specific improvements would change those ratings is the most straightforward path to material insurance savings available to any Tequesta or Jupiter homeowner. This guide walks through the form line by line — in plain English, without the engineering jargon.
What the OIR-B1-1802 Form Is and Who Uses It
The OIR-B1-1802 — formally titled the Uniform Mitigation Verification Inspection Form — is the standardized document required by Florida statute for documenting wind mitigation features of residential properties for insurance rating purposes. Florida Statute 627.0629 requires all authorized insurers to offer premium discounts for wind mitigation features verified through this form, and requires that the form be completed by a qualified inspector — licensed as a general contractor, building inspector, engineer, architect, or home inspector with specific wind mitigation certification.
The form has seven evaluation sections, each corresponding to a specific building system that affects the structure’s wind resistance. Section A covers roof covering — the type and rating of the primary roofing material. Section B covers roof deck attachment — the nail type and pattern connecting the deck to the framing. Section C covers roof-to-wall connections — the type of connection between the roof framing and the wall structure. Section D covers roof geometry — the shape of the roof. Section E covers opening protection — the presence and rating of hurricane shutters or impact-resistant windows and doors. Sections F and G cover wind-borne debris protection for specific opening types.
“The OIR-B1-1802 is not a compliance document — it is a discount schedule. Every line item is a question your insurer has already answered with a dollar value. Knowing what those values are changes how you prioritize every roofing investment.”
The Highest-Value Line Items
While all seven sections of the OIR-B1-1802 contribute to the wind mitigation discount, three sections account for the majority of the premium reduction available to most Palm Beach County homeowners. Understanding which sections carry the most financial weight allows homeowners to prioritize investments for maximum return.
Section A — Roof Covering — is typically the highest-value line item. The roof covering credit distinguishes between non-rated coverings, products meeting the Florida Building Code’s basic requirements, and products with a current Florida Product Approval specifically for the HVHZ. The maximum roof covering credit applies to FPA-listed roofing systems installed after 2001, and to re-roofing projects that used HVHZ-compliant products and were properly permitted and inspected. For homeowners who have recently replaced their roof with a code-compliant system but whose wind mitigation report predates the replacement, updating the report to reflect the new roof covering can alone generate premium reductions of 20 to 35%.
Section A — Roof Covering: Update after every re-roof A new HVHZ-compliant roof not reflected in the current wind mitigation report means you are paying more than necessary. Request an updated inspection immediately after re-roofing.
Section B — Deck Attachment: 8d ring-shank 6/6 for maximum credit The deck re-nailing performed during a re-roof on a pre-2002 home is a direct path to maximum Section B credit. The improvement pays back through insurance savings within the first year.
Section C — Roof-to-Wall: Double wraps for maximum credit The single most impactful standalone structural upgrade for pre-2002 homes. Achievable without a full re-roof and generates immediate mid-term premium adjustment when the updated form is filed.
Section E — Openings: Complete protection requires garage door compliance Impact windows and doors without an impact-rated garage door leave Section E credit incomplete. Garage door upgrade often has the best ROI of any remaining opening protection investment.
Common Errors That Cost Homeowners Money
Wind mitigation inspection errors are more common than the industry acknowledges — and they almost always result in homeowners receiving lower credits than their building features actually support. The errors fall into two categories: inspector documentation errors that incorrectly rate features that are present, and homeowner knowledge gaps that allow incorrect ratings to persist unchallenged.
The most frequent inspector error involves roof covering documentation. Inspectors who cannot access the building permit records for the current roofing system — either because the records are unavailable or because the homeowner cannot provide them — are required to document the roof covering as “non-FPA compliant” even if the installed system is in fact HVHZ-compliant. This default-to-worst rating can cost the homeowner the full Section A credit — the highest-value credit on the form — for the simple reason that permit documentation was not available at the time of inspection. Homeowners who have their building permit number, the Florida Product Approval numbers for their roofing system, and the inspection certificates from the original roofing project can prevent this error entirely.
“An inspector who can’t access your building permit records must default to the lowest roof covering rating — regardless of what’s actually on your roof. Your permit documentation is worth thousands of dollars annually. Keep it.”
Maximizing Your Wind Mitigation Discount
The maximum possible wind mitigation discount — achieved by a home that receives the highest available rating in all seven sections of the OIR-B1-1802 — can reduce the wind portion of a Palm Beach County homeowner’s insurance premium by 60 to 75%. For a luxury coastal property with a $20,000 annual wind premium, this represents $12,000 to $15,000 in annual savings. No home in the existing building stock achieves all seven maximum ratings simultaneously — but understanding which improvements move which ratings creates a prioritized roadmap for working toward the maximum discount systematically.
The strategic sequencing of wind mitigation improvements should begin with the improvements that generate the highest per-dollar premium reduction. For most pre-2002 Palm Beach County homes, this means roof covering first — achieved through re-roofing with HVHZ-compliant materials — followed by roof-to-wall connection upgrade, followed by deck attachment upgrade, and finally opening protection completion for any unprotected openings. This sequence prioritizes improvements by their typical premium impact and by the logical construction sequencing that minimizes redundant work and maximizes shared mobilization costs.
Keep your roofing permit documentation permanently Permit number, FPA numbers for all components, dry-in certificate, and final inspection certificate. These documents are worth their weight in premium savings at every wind mitigation inspection.
Submit updated form mid-term — don’t wait for renewal Florida law requires carriers to adjust premiums mid-term. Every month you delay the updated submission is a month of premium savings forfeited.
Prioritize by premium impact: roof covering, connections, deck, openings Sections A and C generate the largest discounts for most pre-2002 Palm Beach County homes. Start there before investing in lower-return improvements.
Challenge ratings you believe are incorrect Florida law permits homeowners to dispute wind mitigation ratings with supporting documentation. An incorrect toenail rating on a strap-connected home is worth disputing — it could be worth thousands annually.
