We keep posting about mold in your house (for example, crawlspace is a perfect “hiding” spot for it, if you have one in your house please inspect carefully) and if present, how important it is to get rid of it as soon as possible.

But if you are wondering if there are any regulations or standards re mold, the answer is NO. Standards or Threshold Limit Values (TLVs) for airborne concentrations of mold, or mold spores, have not been set. As of right now, there are no EPA regulations or standards for airborne mold contaminants.
