On October 23, 1977, at 3:44 p.m., a two-alarm fire was reported in a hotel room on the 22nd floor, after a bartender in the 27th floor lounge smelled smoke. The entire room had caught on fire from a cigarette. The fire was extinguished with help from 45 firefighters, who put it out within five minutes of their arrival. However, the fire led to heavy smoke infiltrating the entire hotel and ground-floor through elevator shafts. The Landmark was evacuated, and hundreds of guests and employees were allowed to return inside at approximately 5:15 p.m., after smoke had been cleared from the resort's interior. The 22nd through 27th floors had moderate smoke damage. Five hotel guests were treated for smoke inhalation, but none required hospitalization.
