Factors That Affect Flood Insurance Costs in Idaho
In the past, flood insurance rates were impacted only by your general location and flood risk. Your state's historic floods can be found on the FEMA website.
Bannock County has experienced the most flooding, with 52 events since 1996, according to FEMA's Idaho data. The average annual cost of flood insurance in Bannock County is $1,212.
Counties like Lewis, Camas and Gooding have had the least flooding, with three events each and average costs of $1,153, $1,284 and $1,793, respectively.
Even though Bannock County has had the most flood events, its size has kept it from having the highest premiums.
Risk Rating 2.0
FEMA introduced Risk Rating 2.0 in October 2021. In addition to flood mapping, it evaluates the risks associated with a building's structure, its foundation, its elevation and its replacement and repair costs.
The new Risk Rating 2.0 adjusts premiums in a more personalized manner than the previous version. However, where you live still affects the cost of flood insurance.
Flood insurance in Idaho is influenced by the factors listed below.
As a result of the Risk Rating 2.0 assessment of flood risk, you may have a different flood risk than your neighbor. The premiums in moderate and high-risk flood zones can also be significantly higher than those in low-risk zones.
Coverage choices also affect premiums. Rates increase as coverage levels increase. Depending on your county, your premiums will also vary.
Higher deductibles can lower your premiums. Deductible amounts range from $1,000 to $10,000. However, it is your responsibility to pay this fee whenever a claim is filed.
Age of Structure
Based on a structure's construction, insurers assess a property's age. Older structures are subject to higher insurance premiums.
Poorly constructed structures may require more coverage. The construction of your property will be evaluated by your insurance company and will affect your premiums.
Do You Need Flood Insurance in Idaho?
High-risk flood zones require flood insurance if you have a government-backed mortgage. In low and moderate-risk flood zones, FEMA still recommends flood insurance since every home is at risk for flooding.
Typically, flood insurance won't be included in homeowners or renters policies, so you'll have to buy one from the NFIP or privately. Flood insurance claims do not require a presidential disaster declaration. There is a $5,000 limit on federal disaster grants per household, so you may want to buy flood insurance from a private company.
Knowing that you are protected from flooding thanks to insurance is reassuring.
