What does flood insurance cover in a basement?

FEMA says basement coverage under the National Flood Insurance Program is limited, and defines a basement as any area with a floor below ground level on all sides. (FEMA)

  • Building items FEMA lists as examples of covered items: central air conditioners, fuel tanks and fuel, furnaces and water heaters, sump pumps, heat pumps, well tanks and pumps, electrical outlets, switches, junction and circuit breaker boxes, unfinished drywall, attached stairways and foundation elements. Cleanup can include pumping out trapped floodwater and treatment for mold and mildew. (FEMA)
  • Contents: FEMA says contents coverage is bought separately, and in a basement it lists clothes washers and dryers, portable or window air conditioners, and food freezers and the food in them, when connected to power. (FEMA)
  • Examples of exclusions FEMA lists: personal property such as couches, computers and televisions; basement improvements such as finished flooring, finished walls and bathroom fixtures; generators; and dehumidifiers not built into the HVAC system. FEMA also says the policy does not pay to remove non-covered items such as basement carpet. (FEMA)
  • Homeowners policies: Triple-I says flood damage is excluded from standard homeowners and renters policies, and that sewer backups are not covered by a typical homeowners policy or by flood insurance unless added separately. (Triple-I)

Coverage varies by policy. The Rhode Island insurance claims guide describes the general claim process and RI Department of Business Regulation resources.

What safety points do agencies list for flooded basements?

  • Ready.gov warns of the risk of electrocution, says not to touch wet electrical equipment or touch electrical equipment while standing in water, and describes floodwater as possibly contaminated and full of dangerous debris. (Ready.gov)
  • Ready.gov advises that people with asthma, other lung conditions or immune suppression stay out of buildings with indoor water leaks or mold that can be seen or smelled, and that children not take part in disaster cleanup. (Ready.gov)
  • The American Red Cross warns against using gasoline, propane, natural gas or charcoal-burning devices inside a home, basement or garage because of carbon monoxide. (American Red Cross)
  • The EPA says drying wet materials within 24 to 48 hours prevents mold growth in most cases, and that damage from sewage or other contaminated water calls for a professional experienced in cleaning buildings damaged by contaminated water. (EPA)
  • Among flood preparation steps, the CDC lists sump pumps with backup power and backflow valves or plugs on drains, toilets and other sewer connections. (CDC)
