Seller disclosure requirements in Maine

Is a disclosure form required by law?

Yes. The law covers a sale, exchange, installment land contract, or lease with an option to buy of “residential real property,” which means real estate with one or not more than four residential dwelling units (§§ 171-172). The seller prepares the statement; the statute lists what it must contain but the sections I read do not set a single mandatory form.

What does the statement cover?

Section 173 lists the topics, as in force in October 2026:

• Water supply. The type of system. For a private supply: its location, any malfunctions, the date of the latest water test, and any unsatisfactory test or test that found PFAS (a 2025 addition).
• Heating. Type, age, servicing company, last service date, annual fuel use, malfunctions in the past 2 years, and last chimney and vent inspection.
• Waste disposal. For a private system: tank size, type, location and age, leach field location and age, malfunctions, last servicing, and the servicing contractor. Systems in shoreland zones carry extra disclosures.
• Hazardous materials. Presence or past removal of asbestos, lead-based paint (homes built before 1978), radon, underground oil storage tanks, and methamphetamine.
• Known defects. Any known defect. The law defines it as a condition the seller knows about that significantly lowers value, significantly impairs the health or safety of occupants, or, if not fixed, significantly shortens the home’s expected life (§ 171).
• Access. Whether the home is reached by a public way, or by a private road, and who maintains it, including any road association.
• Flood. Whether the home is in a mapped special flood hazard area on the current FEMA map, its flood zone, and a copy of the map panel. Also any flood events, flood damage, flood insurance claims and flood disaster aid during the seller’s ownership.
• Shoreland zoning. Violation notices, pending enforcement, litigation, judgments, and settlements.

Sellers must also hand over the state’s information on arsenic in private water and treated wood (§ 173-A).

Who is exempt?

Section 172 exempts, among others:

What are the timing and cancellation rules?

What happens if a seller does not disclose?

Section 174 states that a transfer “is not invalidated solely because” someone failed to comply, so a missing form does not undo a sale. The sections I read set no fine. Other duties stay in place: § 178 says the disclosure law does not limit any other disclosure duty or any common-law duty to avoid fraud or misrepresentation.

The law also protects honest sellers. The statement is not a warranty and is not part of the contract. A seller may answer “unknown” and does not have to investigate (§ 176). A seller is not liable for an error that was outside the seller’s actual knowledge or came from a public agency or a licensed professional’s report the seller reasonably believed, as long as the seller was not negligent (§ 177).

The statement does not replace an inspection. Section 176 says it may not substitute for inspections or warranties, and the buyer is still expected to inspect. See home inspection costs.

What is the federal lead paint rule?

For most homes built before 1978, federal law requires the seller to give the buyer the EPA lead pamphlet, disclose known lead-based paint and hazards, and provide available reports, before the buyer is bound by a contract, says the EPA. Foreclosure sales and housing built after 1977 are outside the rule.

Is anything else required at closing?

Yes. A buyer of a single-family home or multiapartment building must install smoke and carbon monoxide detectors within 30 days of acquiring or occupying it if none are present, and must sign a certification at closing that they will do so (25 M.R.S. §§ 2464 and 2468). The Real Estate Commission cannot give legal advice or settle disputes; it points consumers to a private attorney (Commission FAQ).
