Florida wind mitigation inspection savings: what a homeowner can actually claim

A Florida wind mitigation inspection documents the wind-resistant features of your home on a standardized state form, and insurers are required by law to apply premium credits for what it verifies. The discounts apply to the windstorm portion of your premium, and for a fully hardened home the credit can reach up to 88% of that windstorm portion [1]. Because the windstorm share can be a large part of a coastal Florida bill, the inspection is one of the few insurance levers a homeowner directly controls. The report is filed on form OIR-B1-1802 and is generally valid for up to five years unless the home changes materially [2].

What the wind mitigation inspection is, and the law behind it

Under Florida Statute 627.711, property insurers must offer discounts, credits, or rate differentials for construction features that reduce hurricane losses, and the inspection must be recorded on the uniform state form [2][3]. The form must be completed by a qualified professional: a licensed home inspector, a general, building, or residential contractor, a professional engineer, or a licensed architect [2]. Florida's Office of Insurance Regulation adopted an updated version of the OIR-B1-1802 form, so confirm your inspector is using the current version before you file [2].

This is not a marketing perk. It is a statutory requirement that carriers price your specific construction, which is why the same house can carry very different premiums before and after the report is on file.

What features does an inspector look for?

The inspection typically takes under an hour and focuses on the parts of the structure that fail first in a windstorm. The main credit categories are:

Roof covering and code compliance

The inspector verifies when the roof covering was installed and whether it meets the applicable Florida Building Code edition. A roof documented to current code standards supports the strongest roof credits.

Roof-to-wall connection

This is often the largest single credit. The inspector looks for how the roof is tied to the walls: toe-nails, clips, single wraps, or double wraps. Metal straps that wrap over the top of the truss score in the highest tier because they resist uplift.

Roof deck attachment

The inspector measures the nail size and spacing holding the roof deck to the trusses. Larger nails at tighter spacing resist the uplift that peels a roof deck off in high wind.

Opening protection

To reach the top opening-protection credit, every opening has to be protected: windows, glass doors, skylights, and the garage door. In the High Velocity Hurricane Zone covering Miami-Dade and Broward, that means impact-rated glass or Miami-Dade product-approved shutters on all of them [4].

Roof geometry and secondary water resistance

The form also records roof shape, because a hip roof, which slopes on all four sides, generally sheds wind loads better than a gable roof and earns a separate credit. Inspectors additionally check for secondary water resistance, a sealed roof-deck layer that limits water intrusion if the covering is torn off in a storm. These are smaller credits than roof-to-wall connection or opening protection, but they contribute to the total and can matter when you are close to a higher tier.

How much can you actually save?

There is no single guaranteed percentage, because carriers apply the credits differently and the windstorm portion varies by home and location. What is fixed is the ceiling: the state's own guidance sets the maximum total wind mitigation discount at up to 88% of the windstorm portion of the premium, and the individual credits are not simply added together, they reduce toward that maximum [1]. Only a home with strong roof credits plus full opening protection approaches that ceiling.

Because the credits apply to the windstorm portion rather than the entire bill, the dollar savings depend on how large your windstorm charge is. For many coastal Florida homes that portion is a meaningful share of the annual premium, which is why a modest inspection fee can pay for itself in the first policy period. Once filed, the report is valid for up to five years unless the structure changes, so the credit applies at each renewal within that window [2].

Older homes can still qualify

A common question is whether a home built in the 1950s can earn credits. It can. Wind mitigation credits are based on documented features, not the original build year, so a re-roof to current code, added roof-to-wall straps, or impact-rated windows can move an older home into higher credit tiers. If you are weighing upgrades on an older property, factor the recurring insurance credit into the payback, not just the sticker cost of the work.

When to schedule the inspection

• When you buy. Order it before closing so you can shop the premium with accurate credits. If you are comparing homes, a buyer consultation can help you weigh each property's mitigation profile against its price.
• After a new roof. A re-roof changes roof covering, deck attachment, and often roof-to-wall credits, so an old report is obsolete.
• At renewal, if it has been about five years. The report can expire, and a fresh one can reinstate credits your carrier may have dropped.

Mitigation features also affect resale, because the next buyer inherits the insurance profile. If you are preparing to list, a home valuation should account for your roof age and opening protection.

Frequently asked questions

How much does a wind mitigation inspection cost, and is it worth it?

Inspection fees are modest relative to a coastal Florida premium. Because the resulting credit applies to the windstorm portion of your bill at each renewal for up to five years, and the maximum discount reaches up to 88% of that windstorm portion for a fully hardened home, the inspection commonly pays back quickly [1][2]. The exact savings depend on your home's features and carrier.

Which single feature saves the most?

Roof-to-wall connection and full opening protection are usually the highest-value credits. The credits are applied toward a maximum rather than summed, so combining strong roof connections with impact-rated or shuttered openings gets you closest to the ceiling [1].

How long is the report good for?

The OIR-B1-1802 form is generally valid for up to five years, provided no material changes are made to the structure and no inaccuracies are found [2]. After that, or after a re-roof, you need a new inspection.

Do all insurers have to honor the credits?

Yes. Florida Statute 627.711 requires insurers to offer premium discounts for verified wind-resistant features documented on the uniform state form [2][3]. If you believe credits were not applied, ask your carrier to review the filed OIR-B1-1802.
