Does Homeowners Insurance Cover Water Damage in California?

Last reviewed: 2026-10-07 · By Flood Zone San Diego

Usually yes when the damage is sudden and accidental, like a burst pipe or failed water heater, and usually no when it comes from outside floodwater or a slow leak that went on for a long time. Flood damage needs a separate flood policy, and the National Flood Insurance Program generally has a 30-day waiting period before coverage starts.

Not legal or insurance advice. Every policy is different. Read your own policy and ask your insurer or agent about your specific situation.

What's usually covered

A pipe or supply line that suddenly bursts
A water heater that suddenly fails
Appliance overflows, such as a washing machine or dishwasher
A roof leak caused by sudden storm damage (the roof repair itself may be treated differently from the water damage inside)
Water used to put out a fire

What's usually not covered

Flooding from outside: rising water from storms, rivers or overflowing channels. This needs flood insurance (FEMA FloodSmart).
Slow, long-term leaks: damage that built up over weeks or months is often excluded as wear and tear or lack of maintenance.
Sewer or drain backup: often excluded unless you added a water backup endorsement.
Mold: often limited to a small dollar cap, or covered only when it results from a covered sudden loss.
The broken part itself: a policy may pay for the water damage but not the worn-out water heater or pipe that caused it.

Flood insurance in San Diego

San Diego is dry most of the year, but it does flood. On January 22, 2024, a storm dropped 2.73 inches of rain at San Diego's airport — the city's wettest January day on record — and hundreds of people were rescued from flooded homes, including in Southcrest and Mountain View (City of San Diego). Many people who were flooded that day had no flood insurance. Flood policies are available through the National Flood Insurance Program and private insurers. NFIP policies generally take 30 days to start, so you can't buy one when a storm is in the forecast and expect it to cover that storm (FloodSmart).

California claim deadlines insurers must follow

California's Fair Claims Settlement Practices Regulations set time limits for insurers. Generally, after you report a claim, the insurer must acknowledge it and start investigating within 15 days, and accept or deny it within 40 days of receiving proof of claim. If it needs more time, it must tell you in writing why and update you regularly (California Department of Insurance).

If you're stuck, the California Department of Insurance consumer hotline is 1-800-927-4357, and you can file a complaint at insurance.ca.gov.

How to document your claim

Stop the source and protect your home from further damage. Policies usually require you to take reasonable steps to prevent more damage.
Photograph and video everything before cleanup: the source, standing water, damaged walls, floors and belongings.
Report the claim promptly and write down the claim number, the adjuster's name and every call.
Keep damaged items until the adjuster has seen them, or photograph them closely, including brand and model labels.
Keep every receipt: emergency service, hotel stays and meals if you have to leave home (many policies cover "additional living expenses").
Get moisture readings and drying logs from your restoration company. Adjusters rely on them.

Do I have to use the insurer's preferred contractor?

In general, you can choose your own licensed contractor. Your insurer may recommend one, and using it may make things simpler, but it's your home. Whoever you choose, check their license on the CSLB website.

Frequently asked questions

Does homeowners insurance cover a burst pipe in California?

Usually, yes. A sudden pipe burst is the classic covered water loss. The insurer may not pay to replace the pipe itself, and you'll pay your deductible.

Does homeowners insurance cover flooding from rain?

Rising outside floodwater is usually excluded from standard homeowners policies and needs separate flood insurance. Rain that comes in through a roof damaged by the storm may be treated differently. Check your policy.

Does insurance cover a slab leak?

Many policies cover the water damage caused by a sudden slab leak, and some cover the cost of accessing the pipe. The pipe repair itself is often excluded. Coverage varies a lot by policy.

How long does an insurer have to respond in California?

Under California's Fair Claims Settlement Practices Regulations, insurers generally must acknowledge a claim within 15 days and accept or deny it within 40 days of receiving proof of claim.
