North Carolina General Statutes Chapter 42. Landlord and Tenant § 42-42.3. Victim protection--change locks

(a) If the perpetrator of domestic violence, sexual assault, or stalking is not a tenant in the same dwelling unit as the protected tenant, a tenant of a dwelling may give oral or written notice to the landlord that a protected tenant is a victim of domestic violence, sexual assault, or stalking and may request that the locks to the dwelling unit be changed. A protected tenant is not required to provide documentation of the domestic violence, sexual assault, or stalking to initiate the changing of the locks, pursuant to this subsection. A landlord who receives a request under this subsection shall change the locks to the protected tenant's dwelling unit or give the protected tenant permission to change the locks within 48 hours.

(b) If the perpetrator of the domestic violence, sexual assault, or stalking is a tenant in the same dwelling unit as the victim, any tenant or protected tenant of a dwelling unit may give oral or written notice to the landlord that a protected tenant is a victim of domestic violence, sexual assault, or stalking and may request that the locks to the dwelling unit be changed. In these circumstances, the following shall apply:

A landlord who receives a request under this subsection shall change the locks to the protected tenant's dwelling unit or give the protected tenant permission to change the locks within 72 hours.

(c) The protected tenant shall bear the expense of changing the locks. If a landlord fails to act within the required time, the protected tenant may change the locks without the landlord's permission. If the protected tenant changes the locks, the protected tenant shall give a key to the new locks to the landlord within 48 hours of the locks being changed.
