I would consult with a “toxic tort” attorney in your area that can advise you of your rights. Unfortunately, the rights vary from state to state so you’ll need someone who is knowledgeable and able to specific regulations in your area. Once you know your rights, you can start down the right path to make sure you have safe housing. Honestly, it is absolutely unfortunate we are in this predicament in the first place which is why creating a solid knowledge base is the best first step to take.
