In the latest issue of People Magazine they talked about Meth houses and the potential health problems associated with living in a house where they once made meth. According to the article, only a few states (not California!) require disclosing any previous meth labs at the home to prospective buyers. Not enough studies have been done to prove that meth chemicals get absorbed in the carpet and walls but the people’s experiences in the article sure seem to prove it. I don’t know how easy it is to check with the local police department to see if a home was ever a meth lab (assuming the lab was discovered by police).
I know if I was buying a house, I’d expect the homeowner to disclose this info if they knew about it.
