⚠️ What Is a Substantial Damage Letter?

If your storm-related home repairs cost 50% or more of your structure’s pre-damage market value, you’ll likely receive this letter from your local floodplain manager. This triggers FEMA’s 50% Rule, which means you may be required to elevate, floodproof, or rebuild your home to meet modern codes.

Why It Matters:

May pause or stop current repairs

Can impact flood insurance eligibility

Often requires new permits or full elevation

Impacts your ability to sell, refinance, or stay insured

🧮 How the 50% Rule Is Calculated

💲 Market Value

Structure-only (no land value)

Based on tax rolls or a private appraiser

🔧 Repair Estimate

Includes labor, materials, electrical, plumbing, walls

Excludes upgrades like a kitchen remodel or deck add-ons

📌 Tip: Many homeowners succeed in challenging inflated repair estimates or undervalued appraisals.

🛠 What to Do Immediately

✅ Step 1: Review the Letter

Is the valuation accurate?

Are repair estimates itemized and realistic?

What’s the deadline to appeal (often 30 days)?

✅ Step 2: Document Everything

Take photos of all damage

Keep contractor estimates, permits, and receipts

Save all communications with your county or FEMA

📉 If You Want to Appeal
