Home warranties come up in virtually every real estate transaction I handle on the Peninsula, and they generate more confusion than almost any other component of the deal. Sellers wonder whether offering one will strengthen their position. Buyers wonder whether to request one and whether to renew it after the first year. Both sides frequently misjudge what these policies actually do. After nearly 20 years in this market, here is my honest assessment of when a home warranty makes sense and when the money is better deployed elsewhere.
Key Takeaways
- A home warranty is a service contract covering repair or replacement of specific home systems and appliances — it is not a substitute for homeowners insurance
- About 80% of homes sold in California include a home warranty, making them a standard expectation in most transactions
- Coverage and exclusions vary significantly by policy — reading the contract carefully before purchasing matters more than brand recognition
- For high-value Peninsula homes, standard warranty coverage limits often feel inadequate relative to the actual repair or replacement costs of premium systems and appliances
- Sellers benefit most from warranty coverage during the listing period; buyers benefit from the transition-period protection a warranty provides in the first year of ownership
What a Home Warranty Actually Covers
A home warranty is an annual service contract that covers the repair or replacement of specific home systems — typically HVAC, plumbing, electrical, and water heaters — and appliances such as refrigerators, dishwashers, ovens, and washers and dryers. When a covered item fails, you pay a service call fee (typically $70 to $100) and the warranty company dispatches a contractor to assess and address the problem.
What home warranties do not cover is equally important to understand. They do not cover pre-existing conditions. They do not cover structural issues, foundation problems, or roof damage in most standard policies. They do not cover items that failed due to lack of maintenance rather than normal wear. And they operate within coverage caps per item — a failed HVAC system that costs $12,000 to replace may be covered only up to $3,000 to $5,000 depending on the policy, leaving the homeowner to cover the remainder.

What is typically covered in a standard California home warranty:
- HVAC systems (heating and air conditioning)
- Plumbing systems and stoppages
- Electrical systems
- Water heater
- Kitchen appliances: refrigerator, dishwasher, oven and range, built-in microwave
- Washer and dryer (sometimes included, sometimes an add-on)
- Garage door opener
Pools, spas, second refrigerators, septic systems, and well pumps are typically available as add-ons, which matters for many larger Peninsula properties.
The Case For a Home Warranty
The strongest argument for a home warranty is straightforward: it converts unpredictable large repair costs into predictable small service call fees. For buyers moving into a home whose systems and appliances are of unknown condition or aging reliability, that predictability has real value during the first year of ownership when financial demands are typically elevated.
From a seller's perspective, offering a warranty during the listing period provides meaningful protection against a difficult scenario: a covered system fails during the inspection period or early in escrow, creating a repair negotiation that complicates or threatens the transaction. Seller-period coverage is inexpensive — often around $65 for the escrow period — and can cover a substantial portion of an unexpected repair cost that would otherwise require out-of-pocket resolution or negotiation credit.
Approximately 80% of homes sold in California include a home warranty, which means buyers in this market have come to expect it. Offering one as a seller is a low-cost gesture that signals confidence in the property and removes a potential friction point.

The Case Against — or at Least for Careful Evaluation
For luxury homes on the Peninsula — Woodside, Portola Valley, Atherton, Menlo Park — the standard home warranty calculus deserves scrutiny. Here is why:
High-end properties often feature premium systems and appliances with replacement costs that substantially exceed standard warranty coverage caps. A Sub-Zero refrigerator or Wolf range that costs $8,000 to $12,000 to replace is not going to be made whole by a policy with a $2,000 per-appliance cap. A high-efficiency HVAC system serving a 6,000-square-foot home may cost $15,000 to $20,000 to replace — well beyond the typical $5,000 to $6,000 HVAC coverage limit in most plans.
There are also service quality considerations. Warranty companies use their own contractor networks, which means you do not necessarily get the specialist or service provider you would choose independently. For property owners who value specific relationships with trusted contractors — a reasonable preference in this market — that loss of control over who works on the property is a genuine downside.
And the fundamental economics of any insurance product apply here: warranty companies price their contracts to be profitable across their full book of business. For homeowners with newer or recently serviced systems and appliances, self-insuring through a dedicated maintenance reserve may generate better long-term financial outcomes than paying annual premiums for coverage with meaningful exclusions.

Making the Right Decision for Your Situation
The right answer depends on the specific property, its systems, and where you are in the transaction.
When a home warranty makes strong sense:
- You are a buyer taking over a home with older systems or appliances of uncertain recent maintenance history
- You are a seller in escrow and want coverage against a covered system failure complicating the transaction
- The property has standard systems and appliances within normal warranty coverage ranges
- You want the psychological comfort of a safety net during the first year of a new ownership
When careful scrutiny is warranted:
- The property has premium appliances and systems with replacement costs that significantly exceed standard coverage limits
- The systems are recently replaced or under manufacturer warranty
- You have a strong preference for controlling which contractors work on your home
- You are a repeat buyer with a robust maintenance reserve and comfort managing vendor relationships
FAQs: Home Warranties on the Peninsula
Should I ask for a home warranty when buying a Peninsula property?
It is a reasonable ask in most transactions, and sellers expect it. The more important question is whether you understand what the warranty actually covers relative to the specific systems and appliances in the home you are purchasing. If the home has high-end appliances or systems with replacement costs well above standard caps, supplement the warranty with a realistic understanding of your out-of-pocket exposure on a worst-case failure.
Is renewing the warranty after the first year worth it?
This is where the economics deserve fresh evaluation. In the first year, the warranty provides genuine value as a bridge through the uncertainty of new ownership. After year one, you know the systems better. You have your own contractor relationships. Renewal makes sense when systems are aging and the risk profile has changed; it makes less sense when systems are newer and the covered risks are lower.
Do I need to disclose foundation or roof issues if I have a home warranty?
Yes, unequivocally. A home warranty does not cover these items in most standard policies, and more importantly, California's seller disclosure requirements apply regardless of what coverage is in place. Full disclosure, combined with appropriate pre-listing inspections and repairs, is always the right approach in this market.
Make an Informed Decision
A home warranty can be a sensible tool or an underperforming expense depending on the specific property and situation. I walk every buyer and seller I work with through this decision in the context of their specific transaction, because the right answer genuinely varies.
