Homeowners insurance pays for sudden accidental damage from a covered peril. A home warranty is a service contract for things that wear out. Neither covers everything.
Homeowners insurance pays when something sudden and accidental damages your house. A home warranty pays when something inside your house wears out and stops working. They do not overlap, and between them they still leave real gaps. The sentence that settles most arguments comes from the National Association of Insurance Commissioners, in its consumer guide to home insurance: a homeowners policy is not a maintenance contract; it insures against damage from perils such as fire, wind and hail, and it does not pay to repair items that simply wear out.
The legal difference, which drives everything else
Homeowners insurance is insurance. Your state insurance department regulates it, the insurer must be licensed in your state, and the policy is built around perils.
A home warranty is usually not insurance. It is a service contract. The same NAIC guide describes a home warranty as covering the mechanical breakdown of individual parts of a home, such as the electrical and plumbing systems, and warns that it might not be regulated as insurance in your state.
That warning is not pedantry. The NAIC model law adoption chart for service contracts and extended warranties, dated Spring 2023, shows the regulatory picture fragmenting by state. Some states have adopted the NAIC Service Contracts Model Act, which places service contracts under the jurisdiction of the insurance department. Others go the other way entirely: the Pennsylvania entry states that service contracts shall not be construed to be the business of insurance and shall be exempt from regulation. California takes a third route and regulates them as home protection contracts through the Department of Insurance.
The practical consequence is about what happens when you are denied. If your insurer denies a claim, you have a state regulator with clear authority over that company. If a home warranty company denies a claim, whether you have that depends entirely on which state you live in. Find out before you buy, not after.
What homeowners insurance actually excludes
The standard HO-3 form is the most common homeowners policy in the United States, and the exclusion language is short and unambiguous. In the sample HO-3 policy published by the Insurance Information Institute, Section I, Perils Insured Against, the insurer states it does not cover loss caused by:
- Wear and tear, marring, deterioration
- Mechanical breakdown, latent defect, inherent vice, or any quality in property that causes it to damage or destroy itself
- Smog, rust or other corrosion, or dry rot
Read that second line again. Mechanical breakdown is excluded by name. That single clause is the entire commercial reason home warranties exist. Your furnace failing of old age is not an insured event and never has been.
Standard policies also exclude flood, and the NAIC guide says so plainly. Earthquake is typically excluded too. Water seeping into a basement is generally treated as a maintenance problem rather than a sudden loss.
What a home warranty actually is
The Federal Trade Commission consumer alert on home warranties, published in February 2023, describes them as really service contracts that typically cover replacements and repairs for things like appliances or air conditioning systems. Its cautions are worth repeating because they are specific: a contract may duplicate coverage you already have, may cover only part of a product, or may make it nearly impossible to get repairs done when you need them.
The California Department of Insurance is blunter still. Its page on home protection contracts states that all home warranties contain dozens of exclusions and that many buyers only discover the exclusions, conditions, and limitations when they file a claim and have it denied.
The FTC broader guidance on extended warranties and service contracts adds two questions most buyers never ask. First, find out who is offering the extended warranty, because it is not necessarily the manufacturer. Second, can the company deny coverage if you do not follow their instructions for routine maintenance? On a home warranty, that second question usually has an expensive answer. Missing annual HVAC servicing is a common documented ground for denial.
The Wisconsin Office of the Commissioner of Insurance, in its consumer fact sheet on warranties dated December 2024, draws the distinction cleanly: service contracts are not warranties, and warranties are included in the price of the product while service contracts cost extra and are sold separately. Its advice on sales promises is the kind you only need once: do not count on the warranty unless the salesperson puts the promise in writing.
Who pays, scenario by scenario
The table below runs concrete household failures against both products. Possibly means it depends on the specific contract, the caps and the maintenance history, which is the honest answer more often than either industry likes to admit.
| What happened | Homeowners insurance | Home warranty |
|---|---|---|
| Windstorm strips shingles off the roof | Yes, wind is a covered peril | No |
| Kitchen fire damages cabinets and walls | Yes | No |
| 14-year-old furnace stops working, worn out | No, mechanical breakdown is excluded | Possibly, subject to caps and maintenance proof |
| Washing machine supply hose bursts and floods the floor | Yes for the resulting water damage to house and contents | Possibly for the machine itself, not the floor |
| Water heater rusts through and fails | No, rust and corrosion are excluded | Possibly |
| AC condenser stops cooling in year 9 | No | Possibly, often capped below replacement cost |
| Roof shingles are simply worn out after 22 years | No, this is maintenance | No, warranties generally exclude the structure |
| Basement seeps after heavy rain | No, seepage is treated as maintenance; flood is excluded | No |
| Visitor slips on your steps and sues | Yes, personal liability coverage | No |
| Laptop stolen in a burglary | Yes, personal property, subject to deductible | No |
Two patterns fall out of that table. Insurance handles the events that could bankrupt you. A warranty handles the events that are merely annoying and expensive. And there is a third column that does not exist: several common failures are covered by neither.
What insurance claims actually look like
Frequency is lower than most people assume. Insurance Information Institute data on homeowners and renters insurance puts the share of insured homes with a claim at 5.33 percent in 2023, down from 6.37 percent in 2020. Roughly one insured home in nineteen filed a claim in 2023.
The composition matters more. Using 2023 figures, wind and hail accounted for 42.5 percent of claims at an average severity of $14,747. Water damage and freezing came to 22.6 percent at $15,400. Fire and lightning were 21.6 percent of claims but averaged $88,170. Theft was 0.6 percent at $5,524, and liability 2.1 percent at $29,880.
That fire figure is the argument for carrying insurance in one number. It is also the argument against treating a home warranty as a substitute for anything. No service contract in the market addresses an $88,000 loss.
On price, the most recent official regulator dataset lags considerably. The NAIC homeowners insurance report for 2022 was not released until 21 May 2025, and it found that HO-3 premiums rose 11.26 percent nationwide between 2021 and 2022, with an average HO-3 premium of $1,569. That is a 2022 figure published in 2025, and anyone quoting a current national average premium to you from an official source is quoting something several years old.
The break-even on a home warranty
No federal agency and no NAIC dataset publishes an average home warranty price, which is itself informative. So here is the arithmetic with the inputs stated openly as assumptions rather than dressed up as data. Assume a plan costing $600 for the year, a $100 fee per service visit, and a $2,000 cap per covered item.
- One approved repair worth $450. You pay $600 plus $100 to avoid $450. You are $250 worse off.
- Two approved repairs worth $450 and $900. You pay $600 plus $200 to avoid $1,350. You are $550 better off.
- One approved system replacement costing $4,500 against a $2,000 cap. You pay $600 plus $100 plus the $2,500 the cap does not reach, for a total of $3,200 against $4,500. You are $1,300 better off, but you still write a $2,500 cheque.
The break-even is simply the annual fee plus the service fees, so with these inputs you need more than $700 of approved covered repairs in a year for the first claim alone to make sense. Substitute the real numbers from the contract in front of you. The cap is the number to check hardest, because a cap set below the real replacement cost of your most expensive covered system converts the product from protection into a partial discount.
The decision rule
Buy a home warranty only if all three of the following are true:
- Two or more of your major covered systems are past ten years old, so the probability of a claim in the coming year is genuinely material.
- An unexpected $2,000 repair bill would cause you real difficulty, meaning you are buying cash flow smoothing rather than expected value.
- The per-item cap in the specific contract exceeds the current replacement cost of your most expensive covered item, and you can produce maintenance records if asked.
If any one of those fails, put the annual fee into a savings account instead and repair things as they break. Over a long enough run, that is what the warranty company is doing with your money, minus its margin.
The gap neither product fills
Between the mechanical breakdown exclusion in the HO-3 form and the structural exclusions in a typical service contract sits a category nobody insures: gradual deterioration of the building itself. Worn roofing, aging siding, failing grading, slow seepage, deteriorating windows. These are the single largest predictable expense of owning a house, and they are uninsurable by design, because they are certain rather than accidental.
One option that does not get discussed enough: some insurers sell an equipment breakdown endorsement on the homeowners policy itself, which addresses part of what a home warranty sells at a fraction of the price and comes with your state insurance department standing behind it. Ask your insurer what it costs before you sign a separate service contract.
The honest version
Homeowners insurance is not optional in any meaningful sense. Your lender requires it, and the fire severity figure explains why you would want it anyway. A home warranty is optional, is often not regulated as insurance where you live, and is priced so that the company expects to win the bet on average. Some households should take that bet anyway, because avoiding a single $3,000 shock in a year when they cannot absorb it is worth paying a margin for.
What neither product does is make an old house cheap to own. The furnace, the roof and the water heater are going to need replacing on a schedule set by their age, and every contract described above is ultimately a way of arranging when you pay for that, not whether.

Frequently asked questions
Will homeowners insurance replace my dead water heater?
Not if it simply failed from age. Insurance responds to covered events like fire or burst pipe damage. Wear and tear breakdowns are exactly the territory warranties claim.
Are home warranties regulated like insurance?
They are service contracts, regulated differently and often less strictly than insurance. Read cap amounts, exclusions, and the claim process closely, and check complaint records before buying.
