Question 1

What exactly is a home seller in California legally required to disclose?

Accepted Answer

Sellers must disclose known material facts that affect a property's value or desirability on the Transfer Disclosure Statement required under Civil Code section 1102, along with a separate Natural Hazard Disclosure and, for most homes built before 1978, a lead-based paint disclosure. Material generally means anything a reasonable buyer would want to know before deciding to buy, which covers more than just structural problems.

Question 2

What if the seller claims they genuinely didn't know about the defect?

Accepted Answer

This is usually the whole fight, since a non-disclosure claim requires proving the seller actually had knowledge. Strong evidence includes prior repair invoices, permit records on file with the city, a past insurance claim, an old inspection report from a sale that fell through, or a neighbor who watched the original problem happen or get patched. Without at least one of these, the case gets considerably harder to win.

Question 3

Does an "as-is" clause in my purchase contract block this kind of claim?

Accepted Answer

No. An as-is clause shifts the risk of defects a buyer reasonably could have discovered themselves, but California law doesn't let it excuse a seller from disclosing something they actually knew about, and it's not a defense to active concealment either. Sellers and their agents raise it often anyway, so don't assume it ends your case before you check.

Question 4

I had my own home inspector before buying, does that hurt my case?

Accepted Answer

It can, for defects a competent inspection reasonably should have caught, since buyers do have a duty to investigate reasonably before closing. It doesn't cover a defect that was actively hidden though, like fresh paint over water damage or a patched crack. The real fight in your case will likely come down to what was genuinely discoverable versus what was deliberately concealed.

Question 5

Can I also bring a claim against the real estate agent, not just the seller?

Accepted Answer

Sometimes, yes. A seller's agent has an independent legal duty to conduct a reasonably competent visual inspection of accessible areas and disclose whatever it turns up, under Civil Code section 2079. Agents also typically carry errors and omissions insurance, which can make them a more realistic source of recovery than a seller who's already moved out of state.

Question 6

Do I have to go through mediation before I'm allowed to file a lawsuit?

Accepted Answer

Almost certainly, if you used the standard California Residential Purchase Agreement, since it contains a mandatory mediation clause. Skipping that step typically means giving up your right to recover attorney fees even if you ultimately win, which is a significant amount to forfeit, so check that clause in your contract before filing anything.

Question 7

How much time do I have to bring a non-disclosure claim?

Accepted Answer

Three years for fraud, counted from when you discovered or reasonably should have discovered the problem, and generally four years for a straightforward breach of contract claim. Since the clock runs from discovery rather than the sale date, don't wait once you've actually found the issue.

Question 8

How is the value of a claim like this typically calculated?

Accepted Answer

Usually the actual cost to repair the defect, or sometimes the difference between what you paid and what the property was genuinely worth given the hidden problem. Punitive damages exist for cases involving real fraud but are rarely awarded at this level. Get two contractor repair estimates, and a formal valuation if the number involved is large.

Question 9

Should I fix the problem right away, or wait until the case is resolved?

Accepted Answer

Fix it now if it's causing ongoing damage, but photograph everything thoroughly before, during, and after the repair, and keep every invoice. If possible, have an independent expert inspect the defect before it's covered by the repair itself, since waiting on litigation while the underlying damage spreads rarely helps your case or your home.

Question 10

Given the amounts involved, is filing this on my own really the right approach?

Accepted Answer

It's a reasonable approach for getting the complaint drafted and filed, since sellers in these cases are usually insured or represented and you should expect a genuine defense in response. If your repair estimate is substantial, it's worth interviewing a couple of real estate litigators first, since some will take a strong non-disclosure case on a hybrid fee arrangement that could end up costing less than doing it entirely alone.
