Florida wind mitigation form (OIR-B1-1802 Rev. 04/26)
What changed on April 1, 2026, what each question asks, and what you need to attach.
What the form is
The Uniform Mitigation Verification Inspection Form (OIR-B1-1802) records the wind-resistant features of a Florida home so an insurer can apply wind premium credits. A qualified inspector completes and signs it after inspecting the property. The revision dated 04/26 is the version to use for inspections on or after April 1, 2026.
What changed in Rev. 04/26
- Updated sections: building code, roof covering, roof deck attachment, roof-to-wall attachment, secondary water resistance and opening protection.
- FORTIFIED Home Roof, Silver and Gold certificates can now be used to validate specific features.
- Region is now based on design wind speed.
- Single-family homes with multiple roof slopes must indicate the slope.
- Inspectors must complete all fields.
The nine questions, in plain English
An optional FORTIFIED Home section comes first. Then come nine questions. The summaries below describe what each one asks, and the official form and your inspection are what decide each answer.
1. Building code
Which version of the Florida Building Code was in force when the original permit application was filed (FBC 2001/2004, FBC 2007 or later, or the South Florida Building Code in the High-Velocity Hurricane Zone). Homes built in 2002/2003 or 2007/2008 need the permit application date.
2. Region
Location based on design wind speed (ASCE 7-22, 700-year MRI, Risk Category 2): HVHZ, Region 1 (140 mph or more), Region 2 (130 to 139 mph) or Region 3 (under 130 mph).
3. Roof slope
For single-family homes with multiple slopes, the slope that makes up at least two thirds of the main roof area: 6:12 or greater, or less than 6:12.
4. Roof covering
4.1 lists every roof covering type in use, with the permit application date or product approval number and the year of original installation or replacement. 4.2 states whether the coverings meet the Florida Building Code or Miami-Dade product approval.
5. Roof deck attachment
The weakest form of roof deck attachment: nail size and spacing of the plywood or OSB sheathing, reinforced concrete, spray foam, other, unknown, or no attic access.
6. Roof to wall attachment
The weakest roof-to-wall connection: toenails, clips, single wraps, double wraps, structural anchor bolts, other, unknown, no attic access, or connections not installed as intended.
7. Roof geometry
Hip roof, flat roof or other roof, based on the share of non-hip features and the roof perimeter and area.
8. Sealed roof deck (secondary water resistance)
Whether a supplemental water barrier is installed, and which kind: fully adhered polymer-modified bitumen underlayment, taped seams, double layer of felt or synthetic, or spray foam.
9. Opening protection
The weakest wind-borne debris protection on any opening, using the Opening Protection Level Chart (levels A, B, C, D, N, X, Z) for windows, doors, garage doors, skylights and glass block.
Photos and documents
The form states that any documentation used to validate a feature must accompany it, and that at least one photograph or document proving the attribute must be attached for each item marked in questions 2 through 9. WindMit Pro adds your photos on pages behind the filled form, grouped by question.
