The short version
To disclose water damage when selling in California, put what you know on the written transfer disclosure statement and deliver it before title passes. Gather invoices, photos and claim papers first, disclose repaired leaks with proof, and let your agent or an attorney word the form.
Do I have to disclose water damage when selling a house in California?
Yes, if the sale falls under the state's transfer disclosure article. California Civil Code 1102.3 says the seller of covered single-family property must hand the buyer a completed written statement as soon as practicable before title transfers. To disclose water damage when selling, put what you know on that form.
The standard form is set out in Civil Code 1102.6. This site is not a law firm or a brokerage, so use this page to get organized, then let your listing agent or an attorney word the answers.
Civil Code 1102.8 adds a second layer. It says the list of items in the article does not limit any other duty to avoid fraud, misrepresentation or deceit in the sale. A short form answer is not a shield if you knew something that mattered and kept quiet.
Which water problems should I write down before listing?
Write down anything you know about water getting into the house, however small and however long ago. Past leaks, flood events, roof repairs, mold and insurance payouts all belong in your notes. Sort them first, then ask your agent how each one belongs on the form.
| What you know | What to gather | Question for your agent |
|---|---|---|
| A pipe or supply line burst and was fixed | Plumber invoice, photos, drying records | How to describe a repaired event. See burst pipe water damage |
| A roof or skylight leaked after a storm | Roofer invoice, ceiling repair receipt | Whether to list the cause and the fix. See roof leak and storm water damage |
| Water came in from outside during a storm | Dates, photos, any claim paperwork | How flooding questions on the form apply |
| Mold was found and removed | Who did the work and what was removed | How to record the growth and the cleanup |
| A stain or soft spot you never traced | Photos with dates, notes on when it appears | What to say about a cause you do not know |
An unexplained stain is the hardest case, because you know it exists but not why. Say so plainly rather than guessing at a cause.
Does a repaired leak still need to be disclosed?
Often it does. A fix does not erase the fact that water got in, and the buyer may care whether the repair held. Whether a given repaired leak belongs on the form is a question for your agent or attorney, but hiding it is the riskier choice.
A repaired leak with paperwork usually reads better than a vague answer. A receipt that names the pipe, roof area or fixture, plus the date, shows a buyer that someone found the source and dealt with it.
If you cannot say who fixed it, say that too. The signs of water damage guide lists what a buyer's inspector may notice, so you know what questions to expect.
What happens if the buyer learns about damage after the disclosure?
The buyer may have a short window to back out. Civil Code 1102.3 says that if a disclosure or a material amendment is delivered after an offer is made, the buyer has three days after hand delivery, or five days after mailing or electronic delivery, to terminate in writing.
That clock is one reason to disclose early. Late news can cost a sale after you have already packed.
It also helps to correct the form if you learn something new. A material change you find mid-sale, such as a leak that returns after rain, goes to the buyer in writing and is not worked out in conversation. Your agent can show you how amendments are handled.
What records should I gather before I list?
Start with paper you already have, then fill gaps with photos and notes. A single folder with dated records lets your agent answer questions quickly and lets you answer them truthfully. Spend an evening on it before the listing goes live.
- Collect invoices and receipts from plumbers, roofers, drying providers and repair work.
- Pull insurance paperwork for any water claim, including the adjuster's report and the settlement letter.
- Gather photos taken before, during and after each repair, with dates.
- Write a short timeline of what happened, when you noticed it and who fixed it.
- List what you never traced, such as a stain with no known cause, so the form answer is accurate.
- Hand the folder to your agent before the first showing, and ask what belongs on the form.
Triple-I advises owners to photograph or video damage and save receipts. The same habit pays off at closing.
Do flood and dam zones add anything to the disclosure?
Yes. Separate from your own water history, Civil Code 1103 requires a seller or agent to say when a home lies in a FEMA special flood hazard area (any Zone A or Zone V type), provided they actually know or a local parcel list applies. A dam failure inundation area is on the same list.
San Joaquin County is a very flat basin with an exceptionally high water table, and Wikipedia says it tends to flood in spring with Sierra snowmelt. The Mokelumne River, which runs past Lodi, has Pardee Dam and Camanche Dam upstream, and Camanche was built mainly for flood control.
Look up the address on FEMA's flood map before you list. The creek and river flooding guide explains how to read flood risk near Acampo, and the flood vs homeowners insurance page covers what a buyer's insurer may ask.
Should I repair water damage before selling or sell as is?
Either can work, and the choice depends on the cause, the cost and your timeline. Fixing the source and drying the area removes the most worrying unknown. Selling as is shifts that work to the buyer, who may price in the worst case.
If you repair, dry the area fast. Mold can start fast, so the EPA says to get wet areas and belongings dry in 24 to 48 hours. The CDPH adds that California has no state license for mold assessors or remediators, so ask any provider how it works and what the paperwork shows.
Check contractors yourself. Since 2025 the CSLB license threshold is $1,000 for labor and materials combined, and its consumer guide limits any home improvement down payment to the lesser of $1,000 and 10 percent of the contract price. The guide to choosing a restoration company has a longer checklist, and water damage repair explains what rebuilding involves.
How does this look from the buyer's side?
A buyer reads the same documents in reverse. They compare your disclosure, the inspection report and their own walk-through, then ask whether the three agree. Where they do not, expect questions, repair requests or a lower offer on the table.
The buying a water damaged house guide shows that reading from the buyer's chair. Seeing it first helps you decide what to fix, what to document and what to explain before an offer arrives.
All of this site's guides are collected in the Acampo water damage guides hub. If the damage is current rather than past, get the source stopped and the area dried first.
