Insurance & Wind Mitigation

Do You Need a Wind Mitigation Inspection in St. Augustine, Florida?

A wind mitigation inspection is not required to buy a home. It documents seven construction features on the state OIR-B1-1802 form that insurers use to set windstorm credits. Here is how it works.

The short answer

No, a wind mitigation inspection is not required to buy a home in St. Augustine or anywhere else in Florida. No law, lender or contract compels one. It exists for a single purpose: to document specific construction features on a standardised state form so that your insurance carrier can apply the windstorm credits it has filed for those features.

The form is the OIR-B1-1802, the Uniform Mitigation Verification Inspection Form, and it is the same document statewide regardless of who performs the inspection. It records what your house has. It does not recommend repairs, it does not grade the house, and it is not a pass or fail exercise. An inspector fills in what is verified, photographs it, and signs it.

Whether it is worth doing is a separate question from whether it is required, and for most St. Augustine homes it is worth doing. Credits vary by carrier and apply only to the windstorm portion of a premium, so we will never tell you what you will save. What we will tell you is that the form is inexpensive relative to a homeowners premium, it stays valid for several years, and a house with qualifying features gets no credit at all until someone documents them.

What the OIR-B1-1802 actually documents

The form covers seven areas. Building code compliance established by permit date, roof covering and its compliance with the applicable code, roof deck attachment, roof-to-wall connections, roof geometry, secondary water resistance, and opening protection. Every one of those is a physical characteristic of the building that an inspector must verify and photograph, not something the homeowner can simply assert.

That is the whole scope. The wind mitigation inspection does not evaluate the condition of the roof, the electrical system, the plumbing or the HVAC. It is not a home inspection and it is not a 4-point inspection. It answers one question: how is this house built to resist wind, in the specific terms Florida insurers price against.

The documentation requirement is the part that surprises people. If the attic is inaccessible, or the roof deck cannot be observed, or there is no permit record establishing a build date, the inspector cannot verify the feature and the form reflects that. Unverified is treated as absent. That is why access matters and why the inspection has to be done properly rather than quickly.

Build-code compliance by permit date and roof covering

The first section establishes when the structure was permitted, because Florida building requirements changed substantially over time and the permit date sets which code applied. For homes in St. Johns County, the county permit record is the source. Where a home was built under a more stringent code, that fact alone affects how the rest of the form is read.

Roof covering is documented separately, and it is about permits and product approval rather than about how the shingles look. The inspector records the covering type, the permit date of the most recent roof installation, and whether documentation exists showing the product meets the applicable code or Florida product approval. A re-roof done under a modern permit is one of the most valuable things a St. Augustine homeowner can have on this form.

This is the single most common gap we run into. A homeowner replaced a roof years ago, the work was fine, and nobody can produce the permit. Pull your permit history from the county before the inspection. If a permit exists, the covering can be documented. If no permit was ever pulled, that is a conversation to have with your agent and, on a purchase, with your realtor.

Roof deck attachment and roof-to-wall connections

Roof deck attachment records how the sheathing is fastened to the framing beneath it, which is verified from inside the attic by observing fastener type, size and spacing. The categories range from older, widely spaced staples or short nails through to larger nails at tighter spacing. This is a real physical inspection: someone has to get into the attic and look at the underside of the deck.

Roof-to-wall connection records how the roof structure is tied to the walls, and it is often the section that carries the most weight in how a house is rated. The categories run from toe nails, through clips, through single wraps and double wraps of metal strapping, up to structural connections in poured or engineered systems. Again it is verified visually in the attic at the truss or rafter ends, with photographs.

Older St. Augustine homes frequently score modestly in both categories, and there is no shame in that. Newer construction in Nocatee, out toward SR 16, and in the newer St. Johns County subdivisions typically documents far better, because it was built under codes that required it. Either way the form records what is there, and a truthful record is what your carrier prices against.

Roof geometry and secondary water resistance

Roof geometry classifies the shape of the roof, most importantly whether it qualifies as hip. A hip roof slopes on all sides and sheds wind loading better than a gable, which presents a flat vertical face to the wind. The form has a specific measurement threshold governing whether non-hip features disqualify the classification, and the inspector measures rather than eyeballs it.

Secondary water resistance documents whether a barrier exists beneath the roof covering to limit water entry if the covering is lost in a storm. In practice this usually means a self-adhering underlayment or a sealed deck system, and it must be verifiable. On many homes it simply is not present, and on many others it is present but cannot be confirmed without documentation from the roofing contractor.

Opening protection

Opening protection documents whether the windows, doors, skylights and garage doors are protected against wind-borne debris, and to what standard. The categories distinguish protection that meets the more demanding large-missile standard from protection that meets a lesser standard, and they require that all openings be protected. One unprotected opening changes the classification for the whole house.

That last point is where most homes lose this section. A house with impact-rated windows throughout but an original garage door, or with shutters for every window except a small bathroom, does not document as fully protected. We check every opening, including skylights and any glazing in entry doors, and we look at whether panels and shutters actually exist on site and whether their tracks and anchors are intact and functional.

In the beach areas, on Anastasia Island and anywhere within the wind-borne debris region, rated opening protection is a code requirement for new work rather than an upgrade, which affects the cost of replacing a window or a sliding door. Corroded shutter tracks that will no longer close are a common coastal finding and a common reason a homeowner believes they have protection they cannot document.

Who should get one, and when

If you are buying a home in St. Augustine, get the wind mitigation inspection during your inspection period and at the same visit as the home inspection. It costs less and takes less time than a separate trip, and it gives your insurance agent what they need while you can still act on the quote.

If you already own your home, get one if you have never had it done, if your existing form is approaching the end of its validity period, or if anything on the list has changed. A re-roof, new impact-rated windows, a new garage door, or added shutters can all change what the form documents. The credits are not applied retroactively for work an insurer does not know about.

How it fits with the rest of your inspections

The wind mitigation inspection is one of three documents that commonly travel together on a Northeast Florida purchase. The full home inspection tells you the condition of the house. The wind mitigation form tells your insurer how it is built to resist wind. And where a carrier asks for one, a 4-point inspection reports on the roof, electrical, plumbing and HVAC systems.

Requirements for a 4-point vary by carrier, so confirm with your insurance agent, realtor or lender whether you need one, and we can include it with your inspection if you do. Bundling all of it into a single visit is how most of our St. Augustine, St. Augustine Beach, Ponte Vedra Beach and Nocatee clients handle it, and it keeps the whole insurance conversation inside the inspection period where it belongs.

One thing to keep straight: none of these three is a wood-destroying organism inspection. That requires a separate Florida licence held under the Department of Agriculture and Consumer Services, and we do not perform it. We document visible evidence and conducive conditions during the home inspection and recommend a licensed WDO inspector, and we are happy to help connect you with one.

Questions

Do you need a wind mitigation inspection to buy a home in Florida?

No. A wind mitigation inspection is never required to purchase a home. It is entirely optional and exists so that your insurance carrier can verify construction features and apply the windstorm credits it has filed for them. Most St. Augustine buyers get one anyway, during the inspection period and at the same visit as the home inspection, because the form takes little extra time and a house gets no credit for qualifying features until someone documents them.

What is the OIR-B1-1802 form?

It is the Uniform Mitigation Verification Inspection Form, the standardised Florida document used to report wind-resistant construction features to an insurer. It covers seven areas: building code compliance by permit date, roof covering, roof deck attachment, roof-to-wall connections, roof geometry, secondary water resistance, and opening protection. Every entry must be verified and photographed by the inspector. It is the same form statewide regardless of who performs the inspection.

How much will a wind mitigation inspection save me on insurance?

We cannot tell you, and you should be cautious of anyone who does. Credits vary by carrier and apply only to the windstorm portion of your premium, not the whole policy. Two identical forms submitted to two different carriers produce different results, and a home with no qualifying features receives no credit. The form reports what your house has; your insurance agent is the only person who can tell you what that means for your rate.

How long is a wind mitigation inspection good for?

The completed form remains valid for several years from the inspection date, after which a carrier will generally want a current one. You should also have a new inspection sooner if anything on the form has changed, such as a re-roof, new impact-rated windows, a new garage door or newly installed shutters. Those changes are not credited until they are documented, so schedule the update after the work is permitted and completed.

Can a wind mitigation inspection be done at the same time as my home inspection?

Yes, and that is how we recommend doing it. Combining the wind mitigation with your home inspection in one visit costs less and takes less time than two separate trips, and it gets the form to your insurance agent while you can still act on the quote. If your carrier also asks for a 4-point inspection, we can include that in the same visit. Call us at 904-806-7679 to schedule.
