Flawlace, LLC, leased unfinished commercial real estate in Las Vegas, Nevada, from Francis Lin to operate a beauty salon. The lease required Flawlace to obtain a “certificate of occupancy” from the city to commence business. This required the installation of a fire protection system. The lease did not allocate responsibility for the installation to either party. Lin voluntarily undertook to install the system. After a month of delays, Flawlace moved out. Three months later, the installation was complete, and Lin leased the premises to a new tenant. Did Flawlace owe rent for the three months between the time that it moved out and the new tenant moved in? Explain. [Tri-Lin Holdings, LLC v. Flawlace, LLC, 2014 WL 1101577 (Nev. 2014)]
