What Do Sellers Have to Disclose in Massachusetts? Seller Disclosure, Explained
Facts last verified August 4, 2026.
Massachusetts does not require home sellers to fill out a general property disclosure form. The state follows caveat emptor — Latin for “buyer beware” — which places the burden of investigation on the buyer. That said, sellers have specific, legally enforceable obligations, and they can never lie when asked a direct question.
How It Works in Massachusetts
Most states hand sellers a multi-page disclosure checklist. Massachusetts does not. Here, the burden falls on the buyer to ask the right questions and get a home inspection to determine the property’s condition.
But caveat emptor is not a blank check. Three hard rules cut through it every time: sellers cannot affirmatively misrepresent a material fact; they cannot actively conceal known defects (painting over water stains, hiding mold behind drywall); and selling “as-is” does not erase liability for fraud or misrepresentation. Massachusetts courts have consistently held that “as-is” language only means the seller won’t make repairs — it does not protect a seller who lied or concealed a problem.
Is There a Mandatory Seller Disclosure Form in Massachusetts?
No — there is no state-mandated general disclosure form. Residential sellers who are not in the business of selling homes have no affirmative disclosure requirement, with one exception: lead paint. Some brokers ask sellers to complete a voluntary Statement of Property Condition to limit their own exposure, but that form is not required by law.
What Is Caveat Emptor?
Caveat emptor is the old common law rule — still followed in Massachusetts — that places the duty of investigation on the buyer, not the seller. As a practical matter, a buyer who skips the inspection and later finds a leaky roof generally has no legal claim against the seller, unless the seller lied or actively hid the problem.
What Must Be Disclosed When Selling a House in MA?
Despite caveat emptor, Massachusetts law imposes four concrete obligations on sellers.
1. Lead Paint (Pre-1978 Homes)
Under Massachusetts and federal law, every seller and any real estate agent involved in the sale must provide the Property Transfer Lead Paint Notification to a prospective buyer before signing a purchase and sale agreement. Sellers must also disclose any known information about lead in the home and provide copies of any lead inspection reports, risk assessments, or compliance letters.
The Massachusetts Lead Law (M.G.L. c. 111, §§ 189A–199B) goes beyond federal minimums by imposing strict liability on owners when a child under six is harmed by lead hazards. Penalties run up to $1,000 per violation under state law — and far higher under federal law — and a botched notification can open the door to consumer protection claims with triple damages.
2. Septic System (Title 5)
If the property has a private septic system, the seller must disclose that in writing and arrange a Title 5 inspection within the two years before the sale. Both the buyer and the local board of health must receive copies of the report. A passing inspection is valid for two years, or three years if the system is pumped annually with documented proof (310 CMR 15.301(1)). A sale cannot close without a passing report — and if the system fails, that result must be disclosed.
3. Smoke and Carbon Monoxide Detectors
This one surprises many sellers. Massachusetts law requires that upon sale or transfer, all homes be inspected for smoke and carbon monoxide detector compliance, and that the local fire department issue a Certificate of Compliance. It is the seller’s responsibility to obtain it. The certificate is valid for 60 days (M.G.L. c. 148, §§ 26F and 26F½); if closing is delayed past that window, a new inspection is required. Schedule early — many fire departments book two to three weeks out.
4. No Active Misrepresentation (Chapter 93A)
Even without a general affirmative disclosure duty, sellers who knowingly conceal hidden material defects can face lawsuits for misrepresentation, fraud, and violations of M.G.L. c. 93A — claims that can arise months or years after closing.
The Broker’s Duty Goes Further Than the Seller’s
A seller’s agent is held to a higher standard. Under 940 CMR 3.16(2), a licensed broker must disclose all facts that might influence a buyer’s decision — whether or not the buyer asks. A broker cannot tell half-truths or actively avoid learning about a suspected problem. This means a buyer who asks the listing agent about flooding, roof age, or past permits is entitled to a complete, honest answer, even if the seller would have been free to stay silent.
A Worked Example
Imagine a 1965 colonial on the North Shore with a private septic system.
| Obligation | What the seller must do |
|---|---|
| Lead paint | Provide the Property Transfer Lead Paint Notification before the P&S is signed |
| Title 5 | Order a septic inspection; deliver the passing report to the buyer and the board of health |
| Smoke/CO detectors | Obtain a fire department Certificate of Compliance (valid 60 days) |
| Direct questions | Answer every question from the buyer or buyer’s agent honestly |
| Active concealment | Cannot paint over water damage, hide mold, or obscure known defects |
| General disclosure form | Not required — no state form exists |
A buyer purchasing this home should order a full home inspection, ask specific questions about the roof, basement, and mechanical systems, and review the Title 5 report before signing the purchase and sale agreement.

FAQ
Does a seller in Massachusetts have to disclose a leaky basement?
Not automatically. Massachusetts is a caveat emptor state, so sellers have no general duty to volunteer information about a leaky basement. If a buyer asks directly, the seller must answer honestly. A seller who actively conceals water damage — for example, by painting over stains — can face fraud and Chapter 93A claims.
What happens if a seller fails to provide the lead paint notification?
Failure to provide the Property Transfer Lead Paint Notification before the purchase and sale agreement is signed can result in civil penalties up to $1,000 per violation under state law, significantly higher penalties under federal law, and potential consumer protection claims with triple damages.
Does caveat emptor apply to the real estate agent too?
No. Licensed agents are held to a higher standard than private sellers. Under 940 CMR 3.16(2), a broker must disclose all facts that might influence a buyer’s decision — whether or not the buyer asks. This duty applies to the seller’s agent, the buyer’s agent, and a transaction facilitator.
Can a seller sell a home with a failed septic system?
Yes, but with conditions. The seller must disclose the failed Title 5 result to the buyer and the local board of health. The parties can negotiate who pays for the repair, or the buyer can walk away. A failed system typically must be repaired within two years regardless of whether the sale closes.
