Updated: May 22, 2024

Advertising & Editorial Disclosure

Homeowners and renters insurance exclude coverage for natural flooding. Thus, you’ll need to purchase a supplemental policy.

Flood insurance premiums are calculated based on individual property risks such as the unit’s elevation, physical structure, location and replacement costs. We encourage North Dakota residents to check their local flood map so they know whether they live in a moderate- or high-risk flood zone.

Flood insurance guards you against significant expenses, regardless of where you live. The Federal Emergency Management Agency (FEMA) notes that just an inch of water can cost you up to $25,000.

Companies That Offer Flood Insurance in North Dakota

It’s possible to purchase a flood insurance policy from the NFIP or a private company. Typically, private insurance providers have two types of policies: a base policy (identical to an NFIP policy) and an excess policy (add-on coverage for the base policy).

While the NFIP is a great option, it may not fit every homeowner’s needs. Hence, private providers are ideal if NFIP coverage is insufficient or if households are outside an NFIP community.

What Does Flood Insurance Cover in North Dakota?

Flood insurance usually covers damages to your building structure and personal possessions. Purchasing flood insurance might save you from paying $25,000 in damages if your house is flooded with just one inch of water.

Flood insurance covers water damage caused by natural weather events. Thus, unnatural water damage such as leaking appliances or broken pipes isn’t included.

Flood insurance doesn’t cover damage to swimming pools, cash, paperwork, decks, patios, landscaping and basement items. If you want to financially protect your vehicle against flooding damage, we recommend comprehensive insurance.

Flood Insurance Building Coverage

In the event of a covered peril, building coverage helps pay for the repair or replacement of your home’s physical structure. With an NFIP policy, you can get up to $250,000 in building coverage.

A few examples include:

  • Foundation walls
  • Electrical systems
  • Plumbing systems
  • Furnaces, central heating and air conditioning
  • Built-in appliances
  • Permanent carpets
  • Built-in furniture

Flood Insurance Contents Coverage

Contents coverage protects you against the cost of repairing or replacing your personal belongings. You can purchase up to $100,000 in contents coverage with the NFIP.

  • Clothing
  • Furniture
  • Electronic equipment
  • Washers and dryers
  • Artwork

Factors That Affect Flood Insurance Costs in North Dakota

Flood insurance providers previously computed a household’s premiums based on its location in a flood zone map. However, FEMA now has an online tool that showcases the historical flood risk of your state and potential flood-related costs.

In North Dakota, Slope County is one of the counties with the least flooding events (eight) and among the cheapest premiums at $519 per year, on average. On the other hand, Richland County has the most flooding events (73), and its rates cost around $803 per year. These rates are based on MoneyGeek’s available cost data for North Dakota counties.

However, Williams County has the priciest premiums, costing $1,690 per year. This is despite the fact that flooding is relatively uncommon in this county, with just 13 flooding events. This could mean that the floods in this county are highly concentrated and damaging.

Risk Rating 2.0

In October 2021, FEMA implemented its Risk Rating 2.0, a system that aims for fairer premium pricing. Risk Rating 2.0 also focuses on an individual’s property risks, including elevation, frequency of flooding and the structure’s foundation type. However, note that your location still plays a huge role in determining your flood insurance cost.

You can check the below table to learn how flood-related factors affect your premiums.

    Age of Structure

    Older structures are usually more expensive to insure as opposed to newer buildings. When calculating your rate, flood insurance companies will also account for the structure’s age.

    Structure Design

    Your flood insurance rate also depends on the home’s design. Certain building materials protect better against flooding damage. For example, those with masonry walls might pay cheaper premiums compared to homeowners with wood frame walls.

Do You Need Flood Insurance in North Dakota?

Almost every property is vulnerable to flooding. Regardless of your county’s flood risk level, purchasing flood insurance is a sound investment. Additionally, those with government-backed mortgages are required to purchase flood insurance if they live in a high-risk flood zone.

Flood insurance carriers must pay claims even if there isn’t an official disaster declaration. These payments must exceed the federal disaster assistance grant or loan of $5,000 per household.

Overall, flood insurance can provide an additional layer of protection and peace of mind.
