Homeowners and renters insurance generally don’t cover floods. The average flood insurance cost in Idaho varies based on factors including flooding frequency, the size of the county and individual risk factors (i.e., elevation, building structure and age).
The Federal Emergency Management Agency (FEMA) recommends getting flood insurance even if you live in a low-risk flood zone since even an inch of water can cause $25,000 in damage. You can find out if your home is in a flood zone by looking at a flood zone map for Idaho.
