Do You Need a Home Warranty? Here's What to Know

09/7/26  |  Stephanie Nash

What a Home Warranty Actually Covers, and Whether You Need One.


By Stephanie Nash

I get asked about home warranties on almost every transaction I work on, usually right around the time a buyer is deciding what to negotiate for or a seller is deciding what to offer. It's a smart question to ask, because a home warranty isn't the same thing as your homeowners insurance, and knowing the difference can save you real money down the line. Here's what I walk clients through when they're trying to decide if a home warranty makes sense for them.

Key Takeaways

  • A home warranty covers system and appliance breakdowns from normal wear and tear, not the sudden damage homeowners insurance covers.
  • Costs typically run $350 to $900 a year, plus a service call fee each time you use it.
  • Claims can be denied for reasons like pre-existing conditions or unapproved repairs, so the fine print matters.
  • California regulates home warranty companies through the Department of Insurance, and you can check a company's license before you buy.

What a Home Warranty Actually Covers

A home warranty, sometimes called a home protection contract, is an annual service agreement that covers the repair or replacement of home systems and appliances that break down from normal wear and tear. That's the key distinction from homeowners insurance, which covers sudden, unexpected damage from things like fire, theft, or storms rather than equipment simply wearing out over time. Most base plans fall into one of three categories, and beyond that, most providers also let you layer on optional add-ons for items that not every home has.

The Main Types of Home Warranty Coverage

  • Appliance-only plans, covering items like refrigerators, dishwashers, and washers and dryers
  • Systems-only plans, covering things like HVAC, plumbing, and electrical systems
  • Combination plans that cover both systems and appliances, usually at a higher premium
  • Optional add-ons for pool and spa equipment, well pumps, and septic systems, which most base plans exclude
  • Additional add-ons some providers offer, like a second refrigerator, a standby generator, or roof leak repair

What a Home Warranty Typically Costs

Home warranty pricing varies quite a bit depending on the provider and the level of coverage you choose. Most plans run between $350 and $900 a year, which usually breaks down to somewhere between $30 and $90 a month. On top of that annual premium, you'll also pay a service call fee, typically $75 to $150, every time a technician comes out to diagnose or repair a covered item. Combination plans and optional add-ons both push the price higher, so it's worth comparing what you actually need against what a plan bundles in by default.

Costs to Budget for Beyond the Monthly Premium

  • A service call fee due at each visit, separate from your annual premium
  • Coverage limits or caps on what the plan will pay per item or per year
  • Any difference between the repair cost and your plan's payout limit, which you'd cover out of pocket
  • Higher premiums for combination plans or optional add-ons like pool, spa, or septic coverage
  • Pricing that can vary by provider and by zip code, so it's worth getting more than one quote

Common Reasons Claims Get Denied

A home warranty can be genuinely useful, but it's not unconditional coverage. Understanding why claims commonly get denied can save you a frustrating conversation later, since coverage limits, maintenance history, and the timing of an issue all factor into whether a claim gets approved.

What to Watch for Before You File a Claim

  • Whether the issue existed before your coverage started, since pre-existing conditions are a common exclusion
  • Whether the system or appliance was properly maintained, since neglect is another common denial reason
  • Whether you had unapproved work done on a covered item, which can void coverage for that repair
  • Whether the repair cost exceeds your plan's stated coverage limit for that item
  • Whether the item falls under an optional add-on you didn't purchase, like pool equipment or a septic system

How California Regulates Home Warranty Companies

A home warranty is not an insurance policy, but California still requires companies that sell them to be licensed for consumer protection. The California Department of Insurance regulates home warranty companies as home protection companies under the state's Home Protection Law, and it maintains license and complaint information that's available to the public. That means before you sign up with a provider, you can actually check their standing rather than relying on marketing alone, which is worth doing given how much variation exists between providers.

What You Can Verify Before Choosing a Provider

  • Whether the company is licensed as a home protection company with the California Department of Insurance
  • The company's complaint history, which the Department of Insurance publishes for consumers to review
  • Whether the contract clearly discloses coverage terms and exclusions, as California law requires
  • Whether the company has a track record of handling claims promptly, based on public complaint data

When a Home Warranty Makes Sense in a Real Estate Transaction

A home warranty isn't required to buy or sell a home in California, unlike homeowners insurance, which most lenders require as a condition of a mortgage. That said, it comes up often as a negotiating tool. Sellers will sometimes offer a one-year home warranty as part of the deal, giving the buyer some cushion against early repair costs on an unfamiliar home, and buyers can also ask for one to be included as part of their offer.

How a Home Warranty Often Factors Into a Sale

  • A seller-paid home warranty offered as a concession during negotiations
  • A buyer requesting a home warranty be included as part of their offer
  • Extra peace of mind for a buyer taking on an older home with aging systems or appliances
  • The option for either party to shop around for a provider rather than accepting the first one suggested
  • A useful cushion during the first year in a new home, when unfamiliar systems are most likely to reveal problems

FAQs

Is a home warranty the same as homeowners insurance?

No. Homeowners insurance covers sudden damage from events like fire or theft, while a home warranty covers systems and appliances that break down from normal wear and tear. Most homeowners end up with both.

Do I have to buy a home warranty to buy or sell a home in California?

No. A home warranty is optional in California, unlike homeowners insurance, which most lenders require. It's often used as a negotiating tool between buyers and sellers rather than a requirement.

How do I know if a home warranty company is legitimate in California?

I'd check whether the company is licensed as a home protection company with the California Department of Insurance, which publishes license and complaint information for consumers to review before signing a contract.
