Sorry - incomplete answer. There is not a required inspection although you can have an inspection done. A certified home inspector can answer your questions and let you know costs involved in the process.
However, it's recent in it's inception so there aren't many properties on there yet. I would have your Buyer's Agent or yourself call the Idaho Department of Health and Welfare and find out how they advise to proceed to determine if the home you are interested in purchasing or renting has ever been deemed a meth home.
