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 Nevada, the landlord is generally responsible for maintaining the rental property in a habitable and safe condition, as per Nevada Revised Statutes (NRS) 118A.290, which outlines the landlord's obligation to maintain the premises. This includes making necessary repairs, except when damage is caused by the tenant's or their guests' negligence or intentional acts. In such cases, the landlord can repair the damage and bill the tenant, typically prohibiting the tenant from making repairs themselves. The lease agreement should clearly define the responsibilities for maintenance and repairs, and it often restricts the tenant's ability to perform any 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, as indicated in NRS 118A.380. In certain situations, a landlord might permit a tenant to maintain and repair the property if they trust the tenant's capability to do so properly. It's important for both landlords and tenants to review their lease agreements and understand their respective rights and obligations under Nevada law.
