Guide to Costco Home Insurance Rates for Members by State in 2026

Costco home insurance rates for members in 2026 depend on the property's location, construction, replacement value, coverage requirements, and individual underwriting factors. Through its partnership with American Family Insurance and affiliated insurers, Costco provides eligible members access to homeowners insurance options and potential membership discounts.

How Costco Home Insurance Rates Work in 2026

Costco offers access to homeowners insurance through American Family Insurance and its affiliated insurance companies. Costco does not directly underwrite these policies or pay insurance claims. Instead, eligible members can explore insurance options and potential discounts through the program.

Home insurance rates are calculated individually rather than according to a single fixed price for all members. The amount a homeowner pays depends on several factors, including:

  • Property location: Local weather risks, construction costs, and claim patterns can influence premiums.
  • Home replacement value: The estimated cost of rebuilding the property affects the amount of dwelling coverage required.
  • Property characteristics: The home's age, construction materials, roof condition, and safety features can affect pricing.
  • Coverage selection: Higher coverage limits and additional protection can change the premium.
  • Deductibles: Choosing a different deductible can affect the amount paid for insurance.

Because these factors differ between properties, homeowners should request a personalized quote rather than rely on a general state average.

Costco Home Insurance Rates by State

In 2026, the availability and pricing of Costco home insurance depend on the state where the property is located. The insurance program does not publish one universal rate applicable to every state and homeowner.

American Family Insurance lists homeowners insurance information for states including Arizona, Colorado, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Minnesota, Missouri, Nebraska, Nevada, North Dakota, Ohio, Oregon, South Dakota, Utah, Washington, and Wisconsin. Other affiliated underwriting companies operate in additional states, subject to product and program restrictions.

When comparing state availability, homeowners should consider the following:

  • State eligibility: Confirm that the Costco insurance program offers home insurance where the property is located.
  • Regional risks: Weather exposure, local rebuilding costs, and insurance claim patterns may influence premiums.
  • Coverage requirements: Required or recommended protection can differ according to local conditions.
  • Underwriting company: The company issuing the policy may vary by state and product.
  • Local policy terms: Discounts, exclusions, and additional benefits may differ by location.

The official Costco insurance website states that its member discount is not available for home insurance in Florida and Tennessee. Availability and eligibility should be confirmed directly before applying.

Discounts Available to Costco Members

Eligible Costco members may qualify for a membership discount on a home insurance policy. The discount is subject to underwriting criteria and state availability, and the amount is not necessarily the same for every customer.

Other potential savings opportunities may include:

  • Home and auto bundling: Combining eligible policies may qualify the household for a multi-product discount.
  • Home security systems: Certain monitored fire or burglar alarms and qualifying sprinkler systems may help reduce premiums.
  • Roof replacement: Some homeowners may qualify for a discount when a roof has been completely replaced and meets the program's requirements.
  • New home discounts: Eligible newly constructed or recently purchased properties may qualify for additional savings.

Costco Executive members may also receive selected home insurance benefits in eligible states. These can include home lockout assistance and reimbursement for certain window glass repairs, subject to policy conditions and limits.

How to Get a Costco Home Insurance Quote

A personalized quote is the most reliable way to understand the premium available for a particular property. Members can start through the official Costco insurance website and enter their ZIP code to check available options.

Before requesting a quote, prepare the following information:

  • Property address and year of construction
  • Roof age and construction details
  • Estimated cost to rebuild the home
  • Desired dwelling and personal property coverage
  • Current insurance policy details
  • Information about security systems and recent improvements

Once a quote is available, compare the premium with other insurers offering coverage in the same area. Make sure the policies have comparable coverage limits, deductibles, and exclusions.

What to Check Before Choosing a Policy

The lowest quoted premium does not always provide the most suitable coverage. Homeowners should review the full policy details before making a decision.

Important considerations include:

  • Whether the dwelling limit adequately covers rebuilding costs
  • Whether personal belongings are covered at replacement cost or actual cash value
  • Whether flood or earthquake coverage requires a separate policy
  • How much the deductible would be after a covered claim
  • Whether roof damage has specific limitations
  • Which member benefits apply to the selected policy
  • Whether the renewal terms and premiums may change

Comparing these details helps homeowners assess both the cost and the protection offered.

Costco home insurance rates for members by state in 2026 vary according to property characteristics, location, coverage choices, and underwriting requirements. Eligible members may qualify for membership discounts, bundling opportunities, and selected benefits, but these offers are not available everywhere. Since standardized rates cannot accurately represent every home, obtaining a personalized quote and comparing equivalent policies is the most practical way to evaluate the available options.
