Massachusetts Home Seller Disclosure Requirements (2026)
Massachusetts does not have a statutory seller disclosure form — instead, sellers disclose through a combination of the Offer to Purchase/Purchase and Sale Agreement, the Lead Paint Disclosure (mandatory for pre-1978 homes), and common law obligations. This makes Massachusetts one of the more complex disclosure environments for FSBO sellers.
Massachusetts Disclosure Framework
Unlike most states, Massachusetts does not require sellers to complete a standardized property disclosure form. However:
Common law fraud and misrepresentation: Massachusetts courts hold sellers liable for concealing known material defects. The absence of a statutory form doesn't reduce your exposure — it means there's no safe harbor. Buyers and their attorneys will ask questions; answer them accurately.
What buyers will ask: In Massachusetts transactions, buyers' attorneys typically include representations in the Purchase and Sale Agreement (P&S). As a FSBO seller, you'll be asked to represent (in writing, in the P&S) the condition of various property elements. Work with a Massachusetts-licensed real estate attorney to ensure your representations in the P&S are accurate.
Home inspection contingency: Virtually all Massachusetts home sales include a home inspection contingency. The home inspector will identify conditions; buyers will raise them. Proactive disclosure of known issues gives you control over the information and prevents inspection surprises from killing deals.
Lead Paint Disclosure — Massachusetts's Strictest-in-Nation Law
Massachusetts has the most stringent lead paint law in the United States for residential properties. Massachusetts General Laws Chapter 111, §197 and Chapter 111A (the Deleading Law) require:
For pre-1978 homes: Federal Lead-Based Paint Disclosure form and EPA pamphlet required.
If children under 6 will reside in the property: Massachusetts law requires the home to be "de-leaded" or "brought into full compliance" before occupancy by a child under 6. This is unique to Massachusetts. If you're selling to a buyer with young children, they may be required to have the property de-leaded before move-in.
Lead inspector involvement: Massachusetts requires lead inspections and certificates of compliance for deleading work. A Massachusetts-licensed lead inspector issues reports and certificates.
Practical implication for FSBO sellers: If your home was built before 1978, the lead paint issue should be addressed in your listing and pre-negotiation. Buyers with children under 6 may require de-leading as a contract condition.
Title V Septic Inspection
Massachusetts's Title 5 (310 CMR 15.00) is the statewide septic system regulation. Before transferring title on a property with a septic system, a Title 5 inspection must be performed by a DEP-certified system inspector. The inspection determines if the septic system "passes" or "fails."
If the system passes: Provide the passing inspection certificate to the buyer. If the system fails: You must remediate (repair or replace the system) or negotiate with the buyer to do so. Failed septic systems are a significant transaction obstacle in Massachusetts.
Title 5 inspections cost $400–$600 and take 1–2 weeks to schedule. Get this done early in the listing process.
Seller's Attorney — Required in Massachusetts
Massachusetts residential closings are handled by attorneys. You'll need a Massachusetts-licensed real estate attorney to prepare and review the Purchase and Sale Agreement, attend the closing, and handle the deed and recording. Attorney fees for Massachusetts closings typically run $900–$1,500.
Flood Zone Properties in Massachusetts
FEMA flood zone disclosure is not formally required by Massachusetts law but is a practical necessity in many Massachusetts coastal communities (Cape Cod, South Shore, North Shore, islands). Buyers' lenders require flood insurance in designated zones; buyers will research it. Provide accurate FEMA flood zone information proactively.
