Selling or Buying a Home With Mold History in Pennsylvania

Pennsylvania's Real Estate Seller Disclosure Law never uses the word "mold" — but the state's own Real Estate Commission has confirmed on the record that mold falls under the disclosure form's hazardous-substances question. A seller who knows about a mold problem and stays silent on the relevant questions is very likely violating the law even though the word "mold" never appears on the form.

What the law actually requires

Pennsylvania's Real Estate Seller Disclosure Law (68 Pa.C.S. §§7301–7315) requires anyone selling real property to disclose "material defects" known to them — a problem that would have "a significant adverse impact on the value of the property" or create "an unreasonable risk to people on the property." Sellers complete a standard disclosure form covering 16 categories, including basements and crawl spaces, water and sewage systems, and hazardous substances.

Where mold actually shows up on the form

The word "mold" isn't printed anywhere on the form. That's a real gap homeowners notice — and the state's own Real Estate Commission has addressed it directly. When a member of the public asked the Commission during rulemaking to add a standalone mold question, the Commission responded on the record that mold conditions are "currently included within Question (14) on the disclosure form" — the hazardous-substances question.

Beyond that catch-all, the form asks several more specific questions a mold problem would typically trigger:

• Basements and crawl spaces (Question 4): whether you're aware of "any water leakage, accumulation or dampness within the basement or crawl space," and whether you know of any repairs or attempts to control water or dampness there.
• Structural (Question 6): whether you're aware of "any past or present water leakage in the house or other structures."
• Water and sewage (Question 8): whether you're aware of any leaks, backups, or other water-system problems.
• Hazardous substances (Question 14): the catch-all question the Commission has confirmed covers mold specifically.

Why this matters if you're selling

If you know about a past or present mold problem, answering "no" or leaving these questions blank isn't a safe workaround just because "mold" isn't the literal word printed on the form — the Commission's own record says otherwise. A seller who willfully or negligently violates the disclosure law can be liable for the buyer's actual damages, with a two-year window from closing for a buyer to bring a claim.

Why this matters if you're buying

Because the law only requires a seller to disclose what they already know, a seller who genuinely doesn't know about a mold problem hasn't necessarily violated anything by not disclosing it. That puts real weight on you as the buyer: an independent inspection before you close is the only way to get your own answer, rather than relying on the seller's form. See Mold Inspection & Testing for what that involves in Adams County specifically.

Not legal advice

This page explains what the disclosure law and the state's own rulemaking record say — it's general information, not advice on your specific transaction. If you're unsure whether a past issue counts as a "material defect" you need to disclose, or how to answer a specific question on the form, talk to a Pennsylvania real estate attorney or your agent before you sign the disclosure statement.

The mold itself still needs handling

Disclosure is about what you say on paper — it doesn't fix anything. For what causes mold in Adams County homes and what remediation typically costs, see Mold Remediation in Gettysburg, PA.
