Introduction

What the Introduction domain tests

A Florida wind mitigation inspection is a visual, non-invasive survey of hurricane-resistance features that insurers use to rate wind coverage. The findings go on the Uniform Mitigation Verification Inspection Form, commonly OIR-B1-1802. The exam tests whether you can identify the rated features, apply the form’s definitions, and avoid claiming more than you verified. This is not a general home inspection, a four-point inspection, or a code-compliance review.

Core rules

  • Inspect only safely accessible areas; do not remove roof coverings, cut drywall, or dismantle components.
  • Report the weakest verified condition, not the best-looking sample.
  • Use the form’s categories exactly. A receipt, permit, or homeowner statement does not replace visual verification.
  • Record limitations and inaccessible areas.

Worked example

A homeowner says the trusses are “strapped.” In the attic you see a metal connector nailed to the top plate but not wrapped over the truss. That is a clip, not a single or double wrap. Mark the roof-to-wall category as clip and explain the limitation. The reasoning: the form rewards uplift resistance from a continuous strap; a clip does not provide the same load path.

Traps that cost marks

  • Calling a clip a strap because it is metal.
  • Marking “hip” from the curb without measuring perimeter.
  • Treating an insurance form as a substitute for field evidence.
