Florida property insurance premiums are among the highest in the country. One of the few levers property managers actually control is the wind mitigation inspection — a formal assessment of how well a building resists hurricane-force wind. A completed OIR-B1-1802 form submitted to your insurer can reduce premiums by 5% to 45% or more, depending on the construction features of each property.
Many property managers manage portfolios where some or all properties have never had a wind mitigation inspection. That's a systematic overpayment that compounds every renewal cycle.
What a Wind Mitigation Inspection Covers
Florida wind mitigation inspections use the standardized OIR-B1-1802 form, promulgated by the Florida Office of Insurance Regulation. The form evaluates six construction features that affect how well a building handles high winds:
- Roof shape: Hip roofs (all sides slope down) perform significantly better than gable roofs (triangular end walls) in high winds. A hip roof is the single highest-value feature on the form.
- Roof covering: Material type and installation year. Newer FBC-compliant roof coverings (installed to Florida Building Code 2001+) receive favorable ratings.
- Roof deck attachment: How the plywood or OSB decking is nailed to the roof rafters. Closer nail spacing and longer nail lengths earn better ratings.
- Roof-to-wall connection: How the roof structure connects to the wall framing. Toenails are the weakest; single wraps, clips, double wraps, and structural anchors each earn progressively better ratings. Double wraps and structural anchors are the highest tier.
- Opening protection: Windows, doors, and skylights rated for impact resistance (Miami-Dade NOA-approved or FBC-compliant impact products). Panels, shutters, and impact glass all qualify. Buildings with full opening protection earn the largest single discount on most policies.
- Secondary water resistance (SWR): A self-adhering underlayment applied to the roof deck that prevents water intrusion if the roof covering is damaged. Presence of an SWR barrier earns a moderate discount.
Discount Ranges by Feature
The math on a real premium is meaningful. On a $10,000 annual premium, a 35% wind mitigation discount saves $3,500 per year. At a $150 inspection cost, that's a 23x return in year one — and the savings recur every year the inspection is valid.
If you manage 20 properties at an average premium of $8,000, and half qualify for a 20% wind mitigation discount, that's $16,000 in annual premium savings across the portfolio. The cost of 20 inspections at $150 each is $3,000. The payback period is approximately 7 weeks. Inspections for properties that don't qualify still provide documentation value and confirm the current rating is accurate.
Who Can Perform a Florida Wind Mitigation Inspection
Florida law restricts who can perform a wind mitigation inspection that qualifies for insurer acceptance. The inspector must be one of the following licensed professionals:
- Florida-licensed building contractor (or general contractor)
- Florida-licensed roofing contractor
- Florida-licensed home inspector
- Florida-licensed engineer
- Florida-licensed architect
- Building official, building inspector, or plans examiner licensed under Florida Statute § 468
The inspector must personally perform the inspection (not delegate it) and sign the OIR-B1-1802 form under penalty of perjury. If an insurer questions the inspection, they may request the inspector's license number and verify credentials with the applicable Florida licensing board.
After major storms, unlicensed individuals offering "wind mitigation inspections" appear in large numbers. An inspection from an unqualified inspector is worthless — the insurer will reject the form and you'll need to pay for a legitimate inspection.

How Long Is the Inspection Valid?
A Florida wind mitigation inspection is generally valid for five years. Insurers will accept a current inspection report at any renewal within that five-year window without requiring a new one.
However, you should get a new inspection immediately — don't wait for the five-year expiration — in these situations:
- After a re-roof: new roof coverings, deck attachments, or SWR barriers can change your rating significantly
- After installing impact windows, doors, or shutters
- After structural improvements to the roof-to-wall connection
- When acquiring a new property with an expired or no inspection on file
When to Get a Wind Mitigation Inspection
The best times to order wind mitigation inspections for your portfolio:
- New policy: Before binding coverage on any new property you manage. If strong features exist, the discount applies from day one.
- 60–90 days before renewal: Allows time to submit the report and have it incorporated into the renewal quote. Last-minute submissions may miss the rating cycle.
- After any qualifying improvement: Impact windows, new roof, structural anchor installation — get a new inspection before the next renewal.
- On acquisition: Any property you take over for management that doesn't have a current inspection on file. The previous manager may have left discounts uncaptured.

Start Free — No Credit Card →The Bottom Line
Wind mitigation inspections are one of the few places where the Florida insurance market works in property managers' favor. The cost is low, the paperwork is standardized, and the savings are recurring. For a portfolio manager responsible for containing insurance costs across multiple properties, a systematic inspection program is straightforward return on a very small investment. Start with your highest-premium properties, work through the portfolio before the next renewal cycle, and schedule reinspections after any qualifying improvement.
Combined with an annual insurance review, wind mitigation inspections are a core part of keeping your portfolio's insurance costs under control in one of the most expensive markets in the country.
