There are two kinds of flood insurance for consumers: one for buildings and one for personal property.
Building policies cover structural damage, to the exterior and foundation, as well as damage to certain, semi-permanent indoor items, such as paneling, heating and cooling systems, carpet, and built-in appliances. Building policies can cover up to $250,000.
Personal property insurance can cover up to $100,000 in damages, and typically applies to portable items. For instance, furniture, clothing, and electronics are considered “personal property,” as are portable appliances, washers and dryers, and artwork.
