When you make an offer on a home in Reading, Wakefield, Andover, or anywhere on the Massachusetts North Shore, you are relying on more than what you can see during a one-hour showing. You are relying on what the seller tells you. And while sellers are human beings who may know things about their property that you cannot observe, Massachusetts law — and the professional norms that govern real estate transactions — establishes clear expectations for what sellers must disclose, what they may choose to disclose, and what they are not legally required to reveal at all.

This is one of the most misunderstood areas of the home-buying and home-selling process. Buyers sometimes assume that sellers are obligated to tell them everything. Sellers sometimes assume that what they do not volunteer cannot create liability. Both assumptions are incomplete. Understanding how seller disclosure works in Massachusetts — particularly in the context of the North Shore’s older housing stock and specific environmental conditions — is essential knowledge for anyone entering the market in 2026.

Massachusetts Disclosure Law: The Foundational Framework

Massachusetts operates under a legal principle called caveat emptor — Latin for “let the buyer beware” — as the baseline for real estate transactions. Unlike some states that require sellers to complete an extensive mandatory disclosure form covering dozens of property conditions, Massachusetts does not have a single comprehensive seller disclosure statute that applies to all residential transactions.

What Massachusetts does have is a combination of:

The result is a system that is less prescriptive than states like California or New York, but that still carries significant legal exposure for sellers who knowingly conceal problems. The line between “I did not know” and “I chose not to tell” matters enormously in any post-closing dispute.

What Sellers Are Required to Disclose in Massachusetts

While Massachusetts does not have an all-encompassing mandatory disclosure form, there are specific categories of information that sellers have clear legal and regulatory obligations to disclose. These are not optional, and failing to disclose them carries real consequences.

Known Material Defects

Under Massachusetts common law and Chapter 93A, sellers have an obligation to disclose known material defects — conditions that would materially affect a reasonable buyer’s decision to purchase the property or the price they would pay. “Material” is the operative word: a minor cosmetic issue is not a material defect, but a history of basement flooding, a failing foundation, active water infiltration, a compromised roof, or a non-functioning HVAC system can all qualify.

The seller must know about the defect for this obligation to apply. A seller cannot be held liable for failing to disclose something they genuinely did not know. However, courts have found that sellers cannot willfully blind themselves — deliberately avoiding knowledge of a problem so they can claim ignorance is not a defense if a reasonable person in their position should have known.

On the North Shore, where much of the housing stock dates to the early to mid-20th century, common categories of known material defects that sellers must address include: structural issues, evidence of water damage or mold, pest infestations (including termites, which are active in parts of Essex and Middlesex Counties), asbestos-containing materials in known disrepair, failing heating systems, and underground oil storage tanks — a particularly significant issue in older Massachusetts homes.

Lead Paint: The Federal Disclosure Requirement Every North Shore Seller Faces

This is the single most universally applicable disclosure requirement on the North Shore, and it applies to virtually every older home in Reading, Wakefield, Lynnfield, Andover, Melrose, Stoneham, Wilmington, Woburn, and Malden.

Federal law (the Residential Lead-Based Paint Hazard Reduction Act) requires sellers of homes built before 1978 to:

Massachusetts adds its own layer through the Childhood Lead Poisoning Prevention Act (CLPPA). Massachusetts law requires that owners of pre-1978 properties rented or sold to families with children under six years old ensure the property is lead-safe. For sellers, the practical implication is that buyers with young children have specific rights under state law, and properties with known lead hazards that have not been addressed may require deleading as a condition of sale.

For North Shore buyers: nearly every property you tour that was built before 1978 — which includes the overwhelming majority of single-family homes in Reading, Wakefield, Andover, and Melrose — will require this disclosure. It does not mean the home is uninhabitable. Many older Massachusetts homes have been properly deleaded, and a deleading certificate is a positive piece of documentation that transfers with the property. But as a buyer, you have the right to review all available lead paint information, and you should.

Title V: Septic System Disclosure and Inspection

Title V of the Massachusetts Environmental Code governs private septic systems, and its requirements apply directly to real estate transactions. This is particularly significant for North Shore communities with large lot sizes and older development patterns — including much of North Reading, portions of Andover, parts of Wilmington, and many of the larger lots in Lynnfield and Reading.

Massachusetts requires that sellers of properties served by a private septic system:

A passing Title V inspection is not a guarantee of long-term system health — it means the system was functional at the time of inspection. But a current passing report is a significant data point for buyers evaluating a property, and its absence is a red flag that warrants investigation. Sellers who have deferred Title V inspections should budget significant time and potentially significant cost if the system requires remediation before sale.

For buyers targeting rural or semi-rural North Shore properties in communities like North Reading or outer Andover: always confirm the Title V status early in your due diligence. A failed septic system or one approaching failure is not necessarily a deal-killer, but it is a major negotiating variable that must be understood before you commit.

Private Well Water Testing

Properties served by private wells rather than municipal water supply carry their own disclosure and testing obligations. Massachusetts does not have a single statewide requirement for pre-sale well testing, but many municipalities have adopted local requirements, and the Massachusetts Department of Environmental Protection recommends testing as best practice.

As a practical matter, most mortgage lenders require water quality testing for properties with private wells before they will fund a loan. This means that even where there is no strict legal disclosure obligation, the transaction process typically forces the issue. Buyers financing with a conventional or FHA loan should expect their lender to require a well water test, and sellers should be prepared to address any identified issues.

Common concerns on older North Shore wells include elevated levels of arsenic (a naturally occurring issue in certain Massachusetts bedrock formations), radon in water, bacteria, and nitrates from agricultural or septic sources. A clean well test is a meaningful assurance for buyers; a contaminated result triggers further investigation and often negotiation over remediation responsibilities.

Underground Heating Oil Tanks

This is one of the most North Shore-specific disclosure issues you will encounter. Thousands of homes across Reading, Wakefield, North Reading, Andover, Melrose, Stoneham, and Wilmington were heated by fuel oil delivered to underground storage tanks (USTs) for much of the 20th century. Many of those tanks were abandoned in place when homeowners converted to natural gas, and their condition — and any historical leakage — can constitute a significant environmental liability.

Massachusetts requires sellers to disclose known underground storage tanks on their property, including tanks that may have been removed or abandoned. Buyers and their attorneys typically inquire about USTs during the due diligence period, and lenders often require tank sweeps or environmental assessments for properties where tank history is uncertain.

If you are selling a pre-1990s North Shore home that was previously heated by oil, be prepared for this question. If you have records of tank removal or have had an environmental assessment done, make those documents available to buyers — their existence significantly reduces buyer concern. If the tank status is unknown, anticipate that buyers will want a tank sweep as part of their due diligence.

The Seller’s Property Disclosure (SPD) Form

While Massachusetts does not mandate a comprehensive disclosure form in all transactions, the Greater Boston Association of REALTORS® Seller’s Property Disclosure (SPD) form is widely used in practice, and many buyers — and their agents — expect to see one.

The SPD is a multi-page form that asks sellers to report their knowledge of conditions in major systems and areas of the property, including:

The SPD is completed to the seller’s knowledge and is not a warranty. Answering “unknown” honestly is acceptable — but answering “no” when the seller knows the answer is “yes” creates significant legal exposure. Courts have treated SPD misrepresentations as the basis for fraud and Chapter 93A claims.

For sellers: complete the SPD carefully and honestly, ideally with your attorney’s guidance. For buyers: read the SPD carefully and note any “unknown” or “yes” responses that warrant follow-up during your inspection and due diligence period.

What Massachusetts Sellers Are NOT Required to Disclose

This is where Massachusetts law differs meaningfully from the expectations many buyers bring to the process. There are several categories of information that sellers in Massachusetts have no legal obligation to disclose:

Stigmatized Property: Deaths, Crimes, and Paranormal Claims

Massachusetts General Law Chapter 93 Section 114 explicitly states that a seller or real estate broker is not required to disclose that a property was the site of a death (including homicide or suicide), a felony, or a claimed paranormal event. These are called “psychologically impacted” or “stigmatized” properties, and Massachusetts law provides that their omission from disclosure cannot form the basis for voiding a contract or for damages.

If a buyer directly asks about a death or criminal event on the property, however, the seller and agent must answer honestly — the protection is from the obligation to volunteer the information, not from the obligation to tell the truth when asked directly.

Neighborhood Conditions Beyond the Property Line

Sellers generally have no obligation to disclose conditions outside their property — a nearby commercial development, a neighbor with a difficult history, traffic patterns, or noise from a nearby venue. Buyers who have concerns about neighborhood conditions should conduct their own due diligence: visit the neighborhood at different times of day and week, research local planning board activity, and ask neighbors directly.

Conditions the Seller Genuinely Did Not Know

As noted above, disclosure obligations are tied to actual knowledge. A seller who genuinely did not know that their basement had a history of water infiltration before they owned the property cannot be held liable for that undisclosed condition — provided they did not take steps to conceal evidence of prior problems. This distinction matters: fresh paint over a water-stained wall is very different from simply not knowing a problem existed.

The “As Is” Sale: What It Means and What It Doesn’t

“As is” is one of the most misunderstood phrases in residential real estate. When a seller lists a property “as is,” buyers sometimes assume this means the seller has no disclosure obligations and that the buyer accepts all risk. That interpretation is incorrect under Massachusetts law.

Selling “as is” in Massachusetts means:

An “as is” sale does not mean:

An “as is” listing on the North Shore often signals that the seller is an estate, a lender (REO/foreclosure), or an owner who simply does not wish to engage in the repair negotiation process. Buyers who purchase “as is” should still conduct a full home inspection — the inspection exists to inform the buyer about what they are buying, even if the buyer has agreed in advance not to request repairs. It is equally important for buyers to have a clear-eyed understanding of what “as is” costs them: if the inspection reveals significant issues, their only leverage is walking away, not requesting concessions.

Radon: A North Shore-Specific Disclosure Consideration

Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. Massachusetts has areas of elevated radon risk, and the North Shore — with its granite-rich geology — is one of them. The EPA action level is 4.0 picocuries per liter (pCi/L); many environmental professionals recommend mitigation at 2.0 pCi/L or above.

Massachusetts does not require sellers to test for or disclose radon unless they have had a test done and the results are available. If a seller has a radon test on file, they should disclose it. If no test has been done, sellers are not required to commission one.

For buyers: radon testing is inexpensive and should be a standard part of your due diligence on any North Shore property with a basement or crawl space. Radon mitigation systems are effective and relatively inexpensive (typically $800–$1,500 for a standard installation), so an elevated result is not a transaction-ending discovery — but it is information you want to have before closing, not after. Most home inspectors offer radon testing as an add-on service.

Mold: Disclosure Obligations and Practical Reality

Massachusetts does not have a specific mold disclosure statute, but mold intersects with the broader material defect framework. A seller who is aware of active mold growth — particularly in areas associated with structural damage, HVAC systems, or water infiltration — has an obligation to disclose it under the general principle that concealing known material defects violates Chapter 93A.

In practice, mold issues on the North Shore most commonly arise from:

If a seller has had a mold remediation company address an issue, that documentation should be available and disclosed. If a seller is aware of conditions likely to produce mold but has not confirmed it, that awareness still matters. Buyers who see water stains, discoloration, or unusual odors during showings should raise those observations with their home inspector and consider a separate mold assessment if warranted.

Condominium-Specific Disclosures on the North Shore

Condominium buyers in communities like Melrose, Malden, Wakefield, and Woburn face an additional layer of disclosure considerations that applies at the association level, not just the unit level. Massachusetts condominium law requires that buyers receive the following documentation as part of their due diligence:

The reserve fund balance is particularly important. A condominium association with a seriously underfunded reserve — unable to cover major shared expenses like roof replacement, elevator maintenance, or parking lot repaving without a special assessment — represents a financial risk for every unit owner. Massachusetts law does not require associations to maintain a specific reserve fund level, but a buyer who reviews the financials and sees a depleted reserve is informed and can make their decision accordingly.

For sellers of condominiums on the North Shore: assembling this documentation early in the listing process is strongly advisable. Delays in providing condo documents are one of the most common sources of transaction friction and closing delays in Massachusetts.

What Happens If a Seller Fails to Disclose a Known Defect?

Post-closing disputes over undisclosed defects are among the most common sources of real estate litigation in Massachusetts. When a buyer discovers a significant problem after closing that they believe the seller knew about and concealed, their options include:

The practical challenge is proof. Establishing that a seller “knew” about a defect requires evidence — prior repair records, permit history, prior listing materials, neighbor testimony, or expert analysis showing that the problem could not have been recent. This is why buyers should retain all transaction documents, disclosure forms, and inspection reports after closing: they are your contemporaneous record of what was represented and what was inspected.

For sellers: the best protection against post-closing disclosure claims is straightforward honesty on the SPD and in all conversations with buyers and their agents. The discomfort of disclosing a known problem upfront — and potentially negotiating a price reduction or repair credit — is always preferable to post-closing litigation.

Practical Guidance for North Shore Buyers: How to Use the Disclosure Process

Understanding the disclosure framework is only valuable if you use it actively during your purchase process. Here is how experienced North Shore buyers approach disclosures:

Practical Guidance for North Shore Sellers: How to Protect Yourself Through Proper Disclosure

Sellers on the North Shore who approach disclosure honestly and systematically protect themselves, their transaction, and their peace of mind. Here is the practical framework that experienced sellers follow:

The North Shore Context: Why Disclosure Matters More Here

The North Shore’s housing stock is older than the national average. In Reading, Wakefield, Andover, Melrose, and most of the communities Susan serves, the median home was built in the 1950s or earlier. That vintage brings genuine character and craftsmanship, but it also brings layers of deferred maintenance, systems updates, and environmental considerations that are simply less common in newer construction markets.

Lead paint is the rule, not the exception. Oil tanks — active or abandoned — are genuinely common. Knob-and-tube wiring and older electrical panels persist in homes that have not been fully updated. Septic systems on larger North Reading and Andover lots vary widely in age and condition. Attic insulation in 1950s ranches often contains vermiculite that may have asbestos contamination.

None of this makes the North Shore a problematic place to buy or sell. It makes it a place where disclosure — done right, by both sides — is the foundation of every successful transaction. Buyers who understand what they are evaluating can make confident decisions. Sellers who disclose honestly protect their legal interests and enable smooth closings.

The alternative — a transaction where disclosure is handled casually, where known issues are buried in fine print or omitted altogether — is the one most likely to end in post-closing conflict, legal fees, and damaged relationships. That is not how the North Shore market works at its best, and it is not how Susan Gormady approaches any transaction she is involved in.

The Bottom Line on Seller Disclosures in Massachusetts

Massachusetts’ disclosure framework is less prescriptive than some states but more consequential than buyers and sellers sometimes realize. For sellers: you are not required to disclose everything, but you are required to disclose what you know that is material — and Chapter 93A means that willful concealment carries real financial stakes. For buyers: the SPD, lead paint addendum, Title V report, and well test results are your primary documentary protections, but they do not substitute for a thorough home inspection and proactive due diligence.

On the North Shore, where the housing stock is old and the market is competitive, the buyers and sellers who navigate disclosure with care, honesty, and the support of experienced professionals consistently have the smoothest transactions and the fewest post-closing problems. It is one of the less glamorous aspects of real estate — no one gets excited about reading a disclosure form — but it may be one of the most important.
