3.2 Maine Property Disclosures

Key Takeaways

  • Maine Title 33 §173 requires sellers of residential property (1–4 units) to deliver a Property Disclosure Statement covering water, heating, waste disposal, hazardous materials, and known defects.
  • The disclosure must be delivered no later than when the buyer makes an offer; if delivered late, the buyer may terminate within 72 hours of receipt.
  • Sellers disclose what they KNOW—there is no duty to inspect or investigate; licensees must pass along all disclosures but do not verify them.
  • Federal law requires lead-based paint disclosure for pre-1978 homes, the EPA pamphlet, and a 10-day inspection opportunity.
  • Maine geology makes radon (action level 4.0 pCi/L) and arsenic in well water leading testing concerns.

Maine Is a Mandatory-Disclosure State

Maine is not a pure caveat emptor ("buyer beware") state. Under Title 33, Section 173, a seller of residential real property (one to four dwelling units) must provide the buyer a Property Disclosure Statement unless the transaction is exempt under §172 (for example, certain transfers between co-owners, by court order, or to a spouse).

Statutory Content (Title 33 §173)

The statement must address, at minimum:

CategoryWhat the Seller Discloses
Water supplyType of system (public or private well), known quality/quantity issues
HeatingHeating system/source and known problems
Waste disposalPublic sewer or private septic system and known issues
Hazardous materialsKnown presence or prior removal of asbestos, lead-based paint (pre-1978), radon, underground tanks, etc.
Known defectsMaterial structural, electrical, plumbing, or environmental conditions the seller knows about

Timing and the 72-Hour Rule

EventRule
Delivery deadlineNo later than the time the buyer makes an offer
If delivered lateBuyer may terminate the contract or withdraw the offer within 72 hours of receiving the statement
FormatWritten; commonly the Maine Association of REALTORS or comparable form

Worked example: A seller forgets to hand over the disclosure until two days after the buyer's offer is accepted. The buyer reads it, sees a noted leaking roof, and cancels within 72 hours—a lawful exit created by the statute itself.

What the Seller Must Know vs. Investigate

Key Point: Sellers disclose what they actually know—the law does not require them to inspect or hire experts. The standard responses are Yes / No / Unknown / N/A.

A seller who marks "Unknown" honestly is protected; a seller who knowingly conceals a material defect (e.g., paints over a chronic basement flood) commits fraud and can be sued.

The Licensee's Role

Licensee DutyStandard
Deliver disclosuresPresent all seller disclosures to the buyer
Disclose known material factsA licensee must reveal material facts they personally know
Verify seller statementsNot required to independently verify the seller's answers
Stigmatized propertyMaine does not require disclosure of deaths, suicides, or alleged paranormal events as material defects

Lead-Based Paint (Federal Overlay)

For homes built before 1978, the federal Residential Lead-Based Paint Hazard Reduction Act requires:

RequirementDetail
DiscloseKnown lead-based paint and hazards
Provide recordsAny prior lead reports/records
EPA pamphlet"Protect Your Family From Lead in Your Home"
Inspection rightBuyer gets 10 days to test (may be waived)
FormFederal lead disclosure form, signed

Warning: Lead disclosure is mandatory federally regardless of any Maine rule, and applies to rentals of pre-1978 housing as well.

Radon in Maine

Radon is a naturally occurring radioactive gas that seeps from soil and bedrock into buildings; it is the leading cause of lung cancer among non-smokers. Maine's granite-rich geology gives it some of the highest radon levels in the United States, in both air and well water.

Radon FactDetail
EPA action level (air)4.0 pCi/L (picocuries per liter)
Sale disclosureSeller must disclose known test results and any installed mitigation system
Rental lawTitle 14 §6030-D requires landlords to test rentals and notify tenants; unmitigated 4.0 pCi/L gives a lease-termination right with 30 days' notice
Best practiceLicensees should recommend buyers test air and water for radon

Exam Tip: On the sale side, Maine law makes radon a known-condition disclosure, not a mandatory pre-sale test. Do not confuse this with the rental statute, which does impose testing duties on landlords.

Underground Storage Tanks (USTs)

Many older Maine homes heated with oil have buried tanks, a known contamination risk.

UST ItemDisclosure
Existing tankLocation, age, and status
Removed tankWhen removed and by whom
Leaking/remediated tankSpill history and remediation status

Septic Systems

Most rural Maine homes use private subsurface wastewater disposal (septic) systems.

Septic ItemDisclosure / Action
System typeTank-and-leach-field, chamber, etc.
MaintenanceLast pumping, repairs, known failures
LocationTank and leach field location
InspectionOften a lender requirement and a buyer contingency; some towns require pump/inspection at transfer

Private Wells and Arsenic

Roughly half of Maine households on private wells face elevated arsenic, plus uranium and radon in groundwater, due to bedrock chemistry.

Recommended TestWhy It Matters in Maine
ArsenicNaturally elevated statewide; linked to cancer and developmental effects
Coliform bacteriaConfirms the water is microbiologically safe
Radon in waterHigh because of granite bedrock
Uranium / nitrate / fluorideCommon secondary contaminants
Flow / yield testConfirms adequate quantity for the household

Worked example: A buyer is purchasing a 1968 farmhouse on a private well with an oil furnace. A prudent licensee recommends: a Property Disclosure review, a septic inspection, an arsenic-and-bacteria water test, a radon (air and water) test, and a check for buried oil tanks—every one of these maps to a real Maine disclosure or contingency.

Disclosure vs. Disclaimer

Selling "as-is" does not waive the statutory disclosure duty. An as-is clause limits the seller's obligation to make repairs; it does not excuse delivering the Title 33 §173 statement or concealing known defects.
