Call the city and ask them to come out and check the building and get a copy of the report. Mold is very dangerous.
Please only call me if your case is in California as I am only licensed here and laws of other states may vary. I approach trials and issues from a legal and common sense approach, This is how the majority of judges I have appeared before in 40 years also make decisions. I do not intend by my advice to enter an attorney client relationship and in most cases advise to obtain legal representation. Sometimes if you can not afford it a consultation or limited scope representation is available. As an experienced attorney I can tell you, judges can be impatient, hate emotional arguments and over exagerations or lies. A brief outline of the problems and desired solutions is always best and I often in limited scope representations advise clients on how to proceed at time of hearing or trial and my fees are considerably less when I do not appear in court as it takes much less of my time.
I agree with the previous answer. In addition, you need to contact your landlord in writing about the problem, even though I assume he is already on notice. The Warranty of Habitability will, based on your circumstances, most probably allow you to reduce your rent, and possibly allow you to arrange temporary housing fully paid until the situation is remedied. Mold is very dangerous and can cause serious health issues for you and your family. I suggest contacting a local attorney to go over all of your rights with you, and it would probably be wise to have said attorney draft a letter to your landlord covering the above. Best of luck to you, and stay safe!
