Miami Metro Wind Mitigation Credits Guide

How Miami metro homeowners can capture wind mitigation credits through inspections and retrofits.

Why Wind Mitigation Is the #1 Lever in South Florida

For most homeowners in the [Miami metro](/guides/miami-metro), the single highest-ROI insurance step is a current **wind mitigation inspection** documented on **Florida form OIR-B1-1802**. Carriers are required by Florida statute to apply credits when the form documents qualifying construction features. Total wind credits commonly reduce the wind portion of premium by **20–45%**, which often translates into **$500–$2,000/yr** in real money on a typical South Florida policy.

The form is valid for 5 years. If yours has expired — or you've never had one — that's likely the largest pool of unclaimed savings on your policy.

What the OIR-B1-1802 Form Evaluates

A licensed Florida wind mitigation inspector documents seven categories. Each can carry a separate credit.

1. Building Code Was the home built to the Florida Building Code (FBC) or the South Florida Building Code? Homes permitted **after March 1, 2002** (FBC adoption) generally qualify for the strongest base credits. In Miami-Dade and Broward, the **High-Velocity Hurricane Zone (HVHZ)** code applies and produces additional credit recognition.

2. Roof Covering Is the roof installed to current FBC standards? Documentation of permits and product approvals (Miami-Dade Notice of Acceptance — NOA) drives this credit.

3. Roof Deck Attachment How is the plywood/OSB deck nailed to the trusses? Options include: - 6d nails at standard spacing (least credit) - 8d nails at standard spacing - 8d nails at 6"/6" spacing or dimensional lumber (largest credit)

4. Roof-to-Wall Attachment This is often the **biggest single credit** on the form: - Toe nails (least credit) - Clips - Single wraps - **Double wraps** (largest credit)

Retrofitting clips or wraps to an older home commonly pays for itself in 1–3 years through credit savings alone.

5. Roof Geometry - Hip roof (largest credit) — commonly 8–20% off the wind premium - Other (gable, flat, complex)

6. Secondary Water Resistance (SWR) A self-adhering polymer-modified bitumen membrane installed over the roof deck seams. Documented SWR triggers an additional credit.

7. Opening Protection Every window, door, and skylight rated for impact or covered by approved shutters. Three tiers: - None - Basic (some openings) - **Hurricane (all openings, including garage door)** — largest credit

In Miami-Dade and Broward HVHZ areas, **Large Missile Impact** rating is required for the highest credit.

How to Get the Inspection

1. **Hire a Florida-licensed wind mitigation inspector**, contractor, engineer, or architect authorized to complete OIR-B1-1802. Cost is commonly **$75–$150**. 2. **Schedule a 60–90 minute inspection** — interior, attic (when accessible), exterior, and roof. 3. **Receive the completed OIR-B1-1802 form** with photos. 4. **Submit to your insurance carrier** for credit application at next renewal.

My Safe Florida Home Program

The state-funded **My Safe Florida Home (MSFH)** program offers two benefits to qualifying owner-occupied single-family homes:

• **Free wind mitigation inspection** by an authorized inspector
• **Matching grants up to $10,000** ($2 from the state for every $1 the homeowner spends) for qualifying retrofits — opening protection, roof-to-wall improvements, secondary water resistance, and roof deck attachment upgrades

Funding is capped each fiscal year and typically opens in waves. Application is through the state portal. The program has been heavily oversubscribed, so apply early when funding rounds open.

Retrofit ROI: What Pays Back Fastest

| Retrofit | Typical Cost | Typical Annual Premium Reduction | Payback | |----------|-------------|----------------------------------|---------| | Wind mitigation inspection only | $75–$150 | $500–$2,000 | < 1 year | | Hurricane-rated garage door | $1,500–$3,500 | $200–$600 | 4–8 years | | Impact windows (full home) | $20,000–$60,000 | $500–$1,800 | 12–25 years | | Storm shutters (all openings) | $4,000–$15,000 | $400–$1,200 | 6–15 years | | Roof-to-wall clip retrofit | $2,000–$6,000 (during re-roof) | $300–$900 | 4–10 years | | Secondary water resistance | $500–$1,500 (during re-roof) | $100–$300 | 3–8 years |

The economics are sharpest when retrofits are bundled into a planned re-roof.

Local Market Context

Miami-Dade and Broward operate under Florida's **High-Velocity Hurricane Zone (HVHZ)** — the most stringent wind requirements in the United States. Products installed in these counties must carry a **Miami-Dade NOA** or Florida Product Approval. Palm Beach falls under the broader Florida Building Code with similar but slightly less restrictive provisions.

Carriers active in South Florida apply the OIR-B1-1802 credits per the state-prescribed credit schedule, which is published by the FLOIR. If you've completed retrofits and your renewal premium hasn't dropped, ask your agent to confirm the form was filed and credits applied.

Action Steps

1. Pull your last wind mitigation inspection — confirm it's within 5 years. 2. If expired or missing, schedule a licensed inspector. 3. Submit the completed OIR-B1-1802 to your carrier and verify credits at next renewal. 4. Check the My Safe Florida Home portal for current funding rounds. 5. Bundle qualifying retrofits with any planned re-roof.

FAQ

How long does a wind mitigation inspection take? Most inspections take **60–90 minutes** on-site. The inspector accesses the attic (if reachable), photographs roof-to-wall connections, reviews permits, and documents opening protection. The form is typically delivered within 1–3 business days.

Will my carrier honor an inspection from a different inspector? Yes — the OIR-B1-1802 is a state form. Any Florida-licensed wind mitigation inspector, contractor, engineer, or architect can complete it. Carriers must apply the credits per the state schedule.

Are impact windows worth it just for the insurance discount? Usually not on premium savings alone — the payback is long. The full case for impact windows in South Florida combines premium savings, hurricane protection (no shutter labor), noise reduction, UV protection, and resale value.

What if my home is too old to qualify for major credits? Pre-2002 homes can still earn credits through retrofits — adding hurricane shutters or impact-rated openings, upgrading the garage door, and during the next re-roof, adding clips/wraps and secondary water resistance. The My Safe Florida Home matching grant is specifically designed for these upgrades.
