Flood Insurance Requirements in USA

In the United States, flood insurance isn’t just a voluntary layer of protection—it’s a critical requirement under multiple circumstances.

  Flood insurance protects against damage from floodwaters—like rising rivers, storm surges, or heavy rainfall—not typically covered under standard homeowners policies FloodsmartAP News.
• Why it matters

• Even private lenders may require coverage regardless of zone FloodsmartInvestopedia.

2. Properties with Past Federal Disaster Aid

If a property has previously received FEMA or SBA disaster assistance, flood insurance must be maintained for future eligibility—even if the homeowner changes Floodsmart.

Properties within Coastal Barrier Resources System (CBRS) or Otherwise Protected Areas (OPA) require flood insurance—even if not in an SFHA—when using a loan secured by the property Selling Guide.
