Your son surely could have found out about his rights as a South Carolina tenant but as long as you made the inquiry, you could pass this link along to him:
No matter where he lives in the USA he is not forced to remain in a house that makes him ill. He could or should have informed a local code enforcement officer or health department. In South Carolina (unlike in NY) he had the right to make a proper repair himself and deduct from the rent (by following certain rules). Depending where he lives he may have access to free legal services.
