In a residential lease, the maintenance and repairs necessary to keep the leased premises in a livable (habitable) and safe condition are generally the responsibility of the landlord—unless damages are caused by the negligence or intentional conduct of the tenant or the tenant’s guests. In that case the landlord will likely maintain the right to make the repairs and charge the tenant for the repairs, and not allow the tenant or the tenant’s contractors to make the repairs.

The written lease agreement should address the responsibility for maintenance and repairs and will often prohibit or limit the tenant’s ability to do any maintenance or make any repairs—at least without the written permission of the landlord. One exception may be the tenant’s right to make repairs in an emergency situation to prevent harm to the property or its occupants.

In some limited circumstances a landlord may allow the tenant to maintain and make repairs to the leased premises when the landlord is confident in the tenant's ability to properly maintain the property and make the necessary repairs.

In North Carolina, landlords are generally responsible for maintaining and repairing rental properties to ensure they are habitable and safe, as per the state's landlord-tenant laws. This includes fixing structural issues, plumbing, heating, and ensuring compliance with health and safety standards. If a tenant or their guests cause damage due to negligence or intentional acts, the landlord can repair the damage and bill the tenant. The specifics of maintenance and repair responsibilities are typically outlined in the lease agreement, which may restrict tenants from making repairs without the landlord's written consent. However, tenants may have the right to make emergency repairs to prevent immediate harm to the property or its occupants. In certain cases, a landlord might permit a tenant to perform maintenance and repairs if they trust the tenant's capability to do so properly. It's important for both landlords and tenants to understand their rights and obligations under the lease agreement and North Carolina law.
