Wind Mitigation Inspections for Gulf County Rental Owners: What to Know Before You Book One

If you own a vacation rental or second home on Cape San Blas, at Indian Pass, in Port St. Joe, at WindMark Beach, or around Mexico Beach, the wind (hurricane) portion of your insurance premium deserves attention. A wind mitigation inspection is a short visit that documents how well your home is built to resist high wind, on a form insurers actually use.

At Renting the Coast, we schedule plenty of vendor visits around guest stays, and wind mitigation inspections come up often after a new roof or at renewal. This guide covers what the inspector looks at, how it differs from a 4-point inspection, and how to fit one in without bumping a booking. For questions about your policy and credits, we point owners to our local insurance partner, Insuring the Coast, the independent agency on Reid Avenue in Port St. Joe.

What a Wind Mitigation Inspection Is (and Why Rental Owners Should Care)

Florida law requires residential property insurers to offer discounts, credits, or other rate differences for construction features that reduce windstorm damage. The Uniform Mitigation Verification Inspection Form, OIR-B1-1802, is the state form used to document those features. Inspections on or after April 1, 2026, use the updated version (Rev. 04/26), which requires photo or document support for each feature claimed.

For rental owners, the point is simple: carriers can only credit what's documented. For how the wind portion fits into the bigger picture, see Insuring the Coast's guide to wind coverage and hurricane deductibles in Florida.

What the Inspector Documents on the OIR-B1-1802

The form covers seven main areas. Knowing them makes your report much easier to read.

Building code year

The inspector notes which Florida Building Code applied when the home was permitted. Homes permitted under the 2001 code or later are generally treated more favorably.

Roof covering

This records the roof covering type and whether it meets the Florida Building Code, usually shown by a permit date or product approval.

Roof deck attachment

This is how the plywood or OSB sheathing is fastened to the trusses: nail size and spacing. It's usually checked from the attic.

Roof-to-wall attachment

This is how the roof is tied to the walls. Common categories, from weakest to strongest, are toe nails, clips, single wraps, and double wraps. Many older coastal homes have toe nails or clips.

Roof geometry

A hip roof slopes down on all four sides and generally performs better in high wind than a gable roof with flat, triangular ends.

Secondary water resistance (SWR)

SWR is a sealed layer under the roof covering, such as self-adhered tape over the deck seams or a full peel-and-stick underlayment, that helps keep rain out if shingles or panels blow off. It's usually added during a reroof, so ask your roofer about it and keep the paperwork. Insuring the Coast also explains how roof claims are paid under replacement cost vs. actual cash value, which is worth reading alongside your roof's age and condition.

Opening protection

This covers windows, doors, skylights, and garage doors. The top category generally requires every glazed opening to be protected with impact-rated products or approved shutters. One unprotected opening can drop the whole home to a lower category.

Who Can Perform It and How Long It's Good For

Florida law (Fla. Stat. 627.711) lists who can sign the form, including licensed home inspectors who have completed hurricane mitigation training, building code inspectors, licensed general, building, or residential contractors, professional engineers, architects, and certified hurricane mitigation inspectors.

A completed form is commonly valid for up to five years, as long as no material changes are made to the structure and nothing on it is found to be inaccurate. Carriers set their own acceptance rules, so confirm with your agent before relying on an older report, especially one from a previous owner. After a reroof or new impact windows or shutters, a new inspection keeps your file current.

How Credits May Affect the Wind Portion of Your Premium

Mitigation credits apply to the wind portion of a property premium, not the whole bill, and each insurer applies them under its own filed rating plan. Two carriers can treat the same report differently, and some homes see little change. A report doesn't guarantee savings; it puts your features on record.

If you're weighing an upgrade, an agent can often compare quotes with and without a feature before you spend money. If your home is insured as a short-term rental, also make sure the policy itself fits that use; Insuring the Coast covers that in its short-term rental insurance overview.

Wind Mitigation vs. 4-Point Inspection

Owners often mix these up, and many inspectors offer both in one visit.

• Wind mitigation inspection: documents wind-resistant construction features. Its main use is figuring out which wind credits may apply.
• 4-point inspection: documents the age and condition of four systems: roof, electrical, plumbing, and HVAC. Carriers commonly ask for one on older homes to decide whether they'll write or renew the policy at all. Age thresholds and requirements vary by carrier.

In short, a 4-point helps answer "will a carrier insure this home?" and a wind mit helps answer "what wind credits may apply?" Buying or switching carriers? Ask your agent which reports are needed.

Scheduling an Inspection Around Guest Bookings

The inspector needs the attic, every window, and the garage, so plan for an empty house:

• Pick a vacant window. A turnover day gap, an owner block, or a midweek opening in the off-season usually works best. Leave a buffer before the next check-in.
• Plan ahead of renewal and hurricane season. A report done well before renewal, and before June 1, gives your agent time to submit it.
• Coordinate access. If Renting the Coast manages your home, let your property manager know the date so it can be held off the booking calendar and access can be arranged.
• Bundle with other work. If a new roof, shutter install, or routine maintenance is already on the calendar, time the inspection right after the upgrade.
