Find the Best Flood Insurance Rates and Companies in Idaho

Thanks to the Boise River, Idaho can be prone to flooding events at any time of the year. Whether it's heavy rainfall or snowmelt, the river can easily overflow, causing widespread flood damage and destruction. Unfortunately, standard business insurance and homeowners insurance won't pay for natural flood damage to your property.

Luckily, a local independent insurance agent in Idaho can help you find the right kind of flood insurance. These agents can compare policies and rates from multiple carriers in your area to find the best deal. For starters, though, here's a closer look at Idaho flood insurance rates, coverage, requirements, and more.

What Does Flood Insurance Cover in Idaho?

Idaho flood insurance coverage protects the structure of a building and its contents, whether it's a home or a business. In Idaho, flood insurance comes in two categories:

  • Buildings coverage: Pays for repairs or rebuilding after natural flood damage to the structure or foundation of your property, including its plumbing and electrical systems, built-in appliances, furnaces, and air conditioning units, and permanently installed carpeting.
  • Contents coverage: Pays for repairs or replacements after natural food damage to personal or business property in your home or business, including clothing, furniture, window treatments, décor, electronics, window air-conditioners, portable appliances, carpeting, and flooring. 

Idaho independent insurance agents can help you get set up with the right amount of flood insurance in each category. 

What's Not Covered by Flood Insurance in Idaho? 

Since Idaho flood insurance doesn't cover personal or business vehicles against flood damage, it's critical to add comprehensive coverage to your auto insurance or commercial auto insurance policy. Further, flood insurance usually excludes coverage for:

  • Preventable damage caused by moisture, mildew, or mold
  • Property and belongings outside of the insured building, such as walks, decks, patios, fences, trees, plants, wells, septic systems, seawalls, hot tubs, and swimming pools
  • Personal property kept in a basement
  • Additional living expenses, such as temporary housing
  • Financial losses caused by business interruption or loss of use of the insured property
  • Currency, precious metals, and valuable papers such as stock certificates
  • Flood damage caused by sewer line breaks or backups*

*If you want to protect your home against flooding caused by sewer backups or line breaks, ask your Idaho independent insurance agent about adding a sewer backup endorsement to your home insurance. 

How Much Does Flood Insurance Cost in Idaho?

Idaho flood insurance costs an average of $927 per year, or approximately $77 per month. This is quite comparable to the current national average flood insurance rate of $899 per year, or approximately $75 per month. 

Local flood insurance rates are set by FEMA and the NFIP using the Idaho flood insurance rate map. Also, Idaho flood insurance rates can be impacted by all of the following:

  • Whether or not your home has a basement
  • Your home's flood zone designation
  • The type of coverage you purchased
  • Your deductible and the amount of coverage you need
  • The value of your home’s contents 
  • The location, design, building materials, and age of your home
