California Water Damage Insurance Claims: Deadlines and Your Rights

Published November 6, 2026 · Last updated November 2026

A water damage claim moves faster when you know the rules. California sets deadlines that insurers must meet, and the state's Department of Insurance and contractor board both publish guidance for homeowners. This guide covers what policies usually pay for, the deadlines, what to document and how to choose who does the work.

Does my homeowners policy cover water damage?

Usually for sudden water damage, but not for flood. The California Department of Insurance (CDI) says homeowners policies don't cover flood damage but do cover other kinds of water damage. It adds that mold damage caused by a covered peril may be covered.

What counts as "sudden" depends on your policy. A burst supply line is the classic covered loss. A slow drip that ran for months may be treated differently. Sewer backups are often limited unless you added coverage. Read the "water damage" and "exclusions" sections of your policy, or ask your agent to walk through them.

Flood is separate

Water that rises from outside is flood, and flood needs its own policy through FEMA's National Flood Insurance Program or a private insurer (CDI flood facts). See our Stockton flood zone guide.

What should I do in the first 24 hours?

Stop the water, take photos and protect your home from more damage. The CDI says your insurer will repay reasonable costs to protect your property as long as you save receipts. It also advises against making big permanent repairs before the adjuster has seen the damage.

1. Stop the source. Close the fixture valve or main shutoff. In Stockton, the City's 24-hour line is (209) 937-8341 for broken pipes and sewer backups (City MUD).
2. Photograph everything before it is moved: the source, each wet room, damaged items and any water lines on walls.
3. Call your insurer to report the claim. Write down the claim number and the name of everyone you talk to.
4. Start drying. The EPA says to dry wet areas within 24 to 48 hours to prevent mold. Fast drying protects your claim as well as your house.
5. Keep every receipt for fans, tarps, hotel stays and emergency work.

How long does an insurer have to handle my claim?

California sets clear limits in its Fair Claims Settlement Practices Regulations. Here are the main ones:

What that looks like on a calendar

Say you report a burst pipe on March 1. By about March 16, the insurer should have acknowledged the claim and started investigating. Once you send proof of claim, the 40-day clock for a decision starts. If the insurer needs longer, you should get a written update every 30 days. After acceptance, payment is due within 30 days.

If a claim is denied, the written denial must tell you that you can have it reviewed by the Department of Insurance (2695.7(b)(3)). Keep a log of dates so you can see if a deadline slips.

What should I document?

• Photos and video of the source, every wet room and every damaged item
• A list of damaged belongings with rough age and price
• Moisture readings or drying logs from the restoration crew
• Every estimate, invoice and receipt
• Notes from every call with your insurer, with dates
• Any written finding from the City or a plumber about where the water came from

Ask the crew for a photo inventory before they pack up or throw out anything. Homeowners have reported items broken or missing after pack-outs, and a list protects you.

Choosing who does the work

Your insurer may suggest a restoration company from its own list. That can be convenient. But some homeowners later wish they had asked more questions, such as who manages the rebuild and how long it will take. Before you agree, ask your insurer whether you may choose your own contractor and how the estimate will be approved.

Whoever you choose, check these California rules:

• License. Jobs of $1,000 or more in labor and materials need a licensed contractor, a threshold that took effect January 1, 2025 (CSLB bulletin). There's no separate state license for water restoration or mold (CSLB classifications).
• Down payment. No more than 10% of the price or $1,000, whichever is less (CSLB).
• After a declared disaster. Contracting without a license in a declared disaster area is a felony (CSLB). San Joaquin County declared emergencies in January and March 2023.
• Right to cancel. Many home improvement contracts carry a 3-day right to cancel, or 5 days for people 65 and older. Some urgent service and repair jobs under $750 are an exception (CSLB).

Read work authorizations carefully

Restoration crews often ask you to sign a work authorization on day one so they can start drying. Read it. Ask what it commits you to, whether it assigns your insurance payment to the company and what happens if the claim is denied. Get the payment schedule in writing.

Common reasons claims slow down

• Missing "before" photos. Without them, it's hard to show what was damaged.
• Repairs done before the adjuster saw the damage. Emergency drying is fine; permanent rebuilds can wait.
• No clear cause. Insurers want to know where the water came from. A plumber's written note helps.
• Estimates that don't match the house. Check room sizes and line items before they go to the insurer.
• Gaps in communication. Keep a dated log, and follow up phone calls with a short email.

What if I disagree with my insurer?

Start with your adjuster and ask for the reason in writing. If that doesn't settle it, the Department of Insurance takes complaints online and through its hotline, 1-800-927-4357. CDI suggests its electronic complaint form, since paper forms may slow things down.

Renters

If you rent, your landlord is responsible for working plumbing and for repairing visible mold or dampness, according to the California Attorney General. Your belongings are covered only by your own renters policy, if you have one.

Who's who

• California Department of Insurance: regulates insurers, takes claim complaints, 1-800-927-4357.
• Contractors State License Board: licenses contractors and handles complaints about them.
• FEMA: runs the National Flood Insurance Program.
