Molds are microscopic organisms found virtually everywhere, indoors, and outdoors. Mold spores are tiny, lightweight, and easily detached by airflow, vacuuming, walking on a carpet or sitting on a couch. In indoor environments, they grow in air-conditioning ducts, carpets, pots of household plants, etc. They produce and release millions of spores, which are small enough to stay airborne threatening to invade the human respiratory system. Due to the health risks associated with mold exposure, certain laws may apply, dealing with such issues as warranties, insurance rights, torts, and others.
Due to the health and safety concerns involved with toxic mold, there is a growing pressure to enact laws which deal with the presence of mold on property. One state's mold legislation includes such provisions as requiring disclosure by sellers of property of known mold on the premises to propective buyers and guidelines for indentification and removal of mold.
