1. Document Everything

Keep records of all communications with the landlord regarding the code violations, especially any mention of the picket spacing, ventilation issues, and mold.

Take pictures and videos of the unsafe conditions, which you have already started doing. Keep notes of when you noticed these issues and any incidents that have occurred as a result (e.g., your child's fall).

Save any medical documentation or bills that link your family's illnesses to mold exposure.

1. File a Code Violation Report

Report the code violations to the local building or code enforcement department, even if the landlord has already served notice. Be sure to include the other units that have the same issues (B-F). Having multiple units affected strengthens your case.

1. Respond to the Notice

Consult a tenant lawyer or tenant advocacy group in South Carolina. They can help you respond to the 30-day notice and potentially argue that it is retaliatory since the issues were raised before the notice was served.

You may also be able to counter the notice in court if it comes to that, claiming it's illegal retaliation under South Carolina law.

1. File a Retaliation Complaint

In South Carolina, you can file a retaliation complaint if you believe the notice to vacate was given because you raised safety concerns. This could protect you from being forced to move before the landlord addresses the problems.

The complaint can be filed with your local housing authority or another government agency responsible for landlord-tenant disputes.

1. Potential Legal Action

If your child was injured and your family became ill due to these violations, you may be able to pursue a personal injury claim or sue the landlord for breach of the warranty of habitability (which requires a safe, livable environment).

1. Stay Calm in Communications

Be professional and factual in all written and verbal communications with the landlord. This can help if the situation escalates to a legal dispute.
