Does Homeowners Insurance Cover Water Damage in California?

Short answer: most standard homeowners policies cover water damage that is sudden and accidental — a burst supply line, a failed water heater, an overflowing washer — and exclude damage that built up slowly over time or came from outside flooding. Your specific policy and your adjuster decide what is covered.

What is usually covered

Sudden pipe or supply-line failures
Appliance leaks such as a washer hose or dishwasher line
Water used to put out a fire
Damage caused by the leak, such as wet drywall, flooring and cabinets

What is often excluded or limited

Long-term leaks: slow drips that went on for weeks or months are often treated as wear and tear.
Flood: water from outside — rising water, storm runoff entering the home — usually needs separate flood insurance.
Mold: many policies cover mold only when it results from a covered water loss, and often with a dollar limit.
The repair of the failed part itself: the policy may pay for the damage but not for the pipe or appliance that failed.

How to protect your claim

Stop the water and take photos and video before cleanup.
Report the loss to your carrier promptly.
Start drying right away — most policies expect you to prevent further damage.
Keep receipts and the restoration company's documentation: moisture readings, drying logs and an itemized scope.
