Over the past decade law enforcement has cracked down on the production of methamphetamine, shutting over 100,000 homemade meth labs. Many of these labs were located in private homes. During production methamphetamine residue lodges in carpets, upholstery, drapes and other surfaces. When these former meth labs are sold unwitting buyers are exposed to the residue and suffer respiratory problems, severe enough in some cases to require the residents to vacate the homes. As reported in The National Law Journal on March 17 some buyers have sued the sellers and brokers involved in the sale for their failure to disclose the property’s former use as a meth lab. The article cites two state trial court decisions–Taylor Bean & Whittaker Mortgage Corp. v Wagner in Ohio and Bloor v Fritz in Washington–involving such claims; the Washington case is on appeal following the trial’s award of $94,000 in damages from the seller and broker to purchasers who were forced to move because of methamphetamine contamination. Fourteen states have passed laws mandating that owners disclose their property’s use for production of methamphetamine, and 13 states require that sellers clean up such former labs before selling them.
