North Carolina General Statutes Chapter 42. Landlord and Tenant § 42-67. Impermissible defense

It shall not be a defense to an action brought pursuant to this Article that the criminal activity was an isolated incident or otherwise has not recurred. Nor is it a defense that the person who actually engaged in the criminal activity no longer resides in the tenant's individual rental unit. However, evidence of such facts may be admissible if offered to support affirmative defenses or grounds for an exemption pursuant to G.S. 42-64.
