Yes, you can legally sell a house that contains lead-based paint, but doing so requires strict compliance with federal and state disclosure laws. In the United States, sellers and landlords are legally obligated under the federal Residential Lead-Based Paint Hazard Reduction Act to disclose any known presence of lead paint, provide buyers with an EPA-approved information pamphlet on lead safety, and include a specific warning attachment in the sales contract. Furthermore, buyers must be granted a federally mandated ten-day window to conduct an independent professional lead inspection or risk assessment before becoming legally bound to the purchase agreement.
