Mold is a potential environmental hazard that tenants should be concerned about. Tenants across the country have won multimillion-dollar lawsuits against landlords for significant health problems - such as rashes, chronic fatigue, nausea, cognitive losses, hemorrhaging, and asthma - that were allegedly caused by exposure to toxic molds in their buildings.
When you suspect mold in your rental unit, learn to look for it and when you might be liable. Even better, take measures to prevent mold from forming before it becomes a problem - or eliminate mold without causing it to grow.
