Which material was used until the late 1970s and must be disclosed?

• A. Lead-Based Paint
• B. UFFI
• C. Private Restrictions
• D. Arm's Length Transaction

Answer: (B)

In real estate disclosures, you must reveal known hazards or materials that could affect health, safety, or value in a property. UFFI—urea-formaldehyde foam insulation—was widely used in homes until the late 1970s. Over time, formaldehyde released from this insulation raised health concerns, leading to regulatory action and the requirement to disclose its presence if known. Because the item in question is specifically tied to usage up to the late 1970s and to a known potential hazard, UFFI is the material that must be disclosed in transactions.

Lead-based paint is also a hazard and has its own disclosure requirements for pre-1978 homes, but the prompt’s emphasis on the late 1970s usage aligns with UFFI as the best fit. Private restrictions and arm’s length transaction are not materials or disclosure items.
