Since flood damage is typically not covered by homeowners and renters insurance, you might end up with a hefty bill to repair flood-related damages. The cost of flood insurance varies depending on numerous factors like your home’s location or foundation type.

Since California has numerous high-risk flood zones, you should check a local flood map to find out if your property is at risk. Those who live in a moderate-risk or high-risk flood zone should strongly consider purchasing flood insurance. According to the Federal Emergency Management Agency (FEMA), an inch of water can cost up to $25,000 in repairs.

What Does Flood Insurance Cover in California?

Flood insurance covers the cost of damage to buildings and their contents. Since an inch of water can cause $25,000 in damages, investing in flood insurance saves you money.

Flood insurance only covers the cost of damage caused by weather or natural events, not damage related to burst pipes or leaking appliances.

Typically, flood insurance doesn’t cover swimming pools, decks, patios or landscaping outside your home. It also doesn’t cover cash, paperwork and vehicles. However, a comprehensive insurance policy covers vehicle flooding.

Flood Insurance Building Coverage

If your home is damaged by a covered cause, flood insurance building coverage can help cover the cost of repairs or replacement to your home. You can obtain up to $250,000 worth of coverage from the NFIP.

Building coverage extends to the following items in the event of damage:

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

Flood Insurance Contents Coverage

If your personal belongings are damaged by a covered peril, contents coverage can cover the cost of repair or the replacement of items. You can purchase up to $100,000 worth of coverage through the NFIP.

Flood insurance contents coverage may apply to the following items:

  • Clothing
  • Furniture
  • Electronic equipment
  • Washers and dryers

Factors That Affect Flood Insurance Costs in California

Prior to October 2021, your location on FEMA’s flood map impacted the cost of your flood insurance. You can check FEMA’s website to view the historical flood risk of your state.

In California, San Bernardino County has the highest number of flood events, with 370 recorded since 1996. However, its average cost of flood insurance is $1,179, lower than the highest in the state, Imperial County, at $2,247. Based on differences in county size, flood events may be more concentrated in Imperial County than San Bernardino. Alpine has the lowest average cost of flood insurance, at $304 per year, and the fewest recorded floods.

Risk Rating 2.0

To make premiums more fair, FEMA introduced Risk Rating 2.0 in October 2021, which changed flood insurance rates to reflect individual property risks instead of solely referencing the number of flood events across an area. Individual factors that impact the cost of your risk rating include:

  • Foundation type
  • Dwelling structure
  • Elevation
  • Replacement and repair costs
  • Frequency of flooding
  • Proximity to bodies of water

Your location can also heavily influence the cost of your flood insurance premium, along with the key factors listed in the table below.

    How your home is designed and the materials it is made out of can also impact your flood insurance rates.

Do You Need Flood Insurance in California?

Regardless of where you live, flood insurance can be a smart investment for possible damages to your home and belongings. For those who live in a high-risk flood zone, lenders and government-backed mortgages require you to buy flood insurance. Although it isn’t legally required for those in a low-risk or moderate-risk flood zone, FEMA still recommends buying flood insurance.

It’s important to note that homeowners' and renters' insurance doesn’t cover flood insurance. While federal disaster assistance can cover up to $5,000 per household, flood insurance provides significantly more benefits. For instance, it covers claims without a presidential disaster declaration.
