On August 30, 2025, at 9:44 PM, the Saratoga County Emergency Communication Center dispatched the Clifton Park Fire Department along with the Clifton Park Emergency Medical Services to 600 London Square for a reported structure fire. The caller reported the balcony was on fire. The fire chief of the department called in route to the scene and immediately notified the dispatcher that he had a heavy column of smoke visible in the distance to transmit the second alarm. Multiple police units quickly arrived on scene and notified the dispatcher that they had a heavily involved balcony fire that was spreading, and they were beginning to evacuate the structure.

The chief arrived on scene and immediately transmitted the third alarm as he had a well involved three story numerous occupancy structure with heavy fire pushing from the roof of the structure with exposure issues on both sides of the structure. The third alarm brought mutual aid from the Jonesville Fire Department, Rexford Fire Department, Boght Fire Company, West Crescent Fire Department, Halfmoon-Waterford Fire Department, for a standby company Malta Fire Department, for a standby company Round Lake Fire Department, Visher Ferry Fire Department, Hillcrest Fire Department, for a standby company Mechanicville Fire Department and additional units from Clifton Park Emergency Medical Services to the scene. The chief met face-to-face with the officers that had been getting people out of the structure, and they notified them that everyone was out of the main fire building and the chief advised them to start to evacuate the adjacent structure as the siding was beginning to melt and smoke from the heavy fire condition in the main fire building. The first arriving engine on scene immediately deployed their large diameter hose at the hydrant and deployed multiple hand lines off of the rig.

The next arriving truck company took the front of the structure and immediately began to set up. The first engine company immediately utilized their water from their deck gun knocking down a significant portion of the heavy fire, but that drained their tank. Firefighters on scene attempted to open up the fire hydrant multiple times but could not get the cap off the front steamer or the side ears as they were painted on. Firefighters deployed additional hose to another hydrant nearby and had the same problem. Additional engines quickly began to arrive on scene and began to supply water to the nearby truck company from their tank supply to get additional water on to the fire. The next arriving engine company into the scene deployed their large diameter hose from the main roadway on route 146 into the scene. Firefighters deployed multiple 35-foot ladders to the rear of the structure to reach the third floor so firefighters can deploy a hand line to the third floor as the stairwell in the front of the structure had been blocked due to the roof giving away due to the heavy fire load.

As they were doing so a firefighter forced open the front cap on the hydrant nearest to the scene and established another crucial water supply. Firefighters in the rear of the structure after establishing an additional water supply climbed to the top floor and began to utilize a hand line from the porch and knock down the visible fire that they could see. Firefighters from the rapid intervention team tossed ladders to the front of the structure where firefighters were working on the third floor. As firefighters were working on the third-floor firefighters retreated back to the area of the balcony and one of the truck companies opened up their master streams quickly knocking down all of the remaining visible fire on the third floor. Firefighters made the white inside of the structure and conducted a secondary search of the building for any remaining occupants or pets. Command requested national grid, Fire Investigator, the American Red Cross, and Jonesville Fire Department rehab bus to the scene. Command requested after the truck companies utilize their master streams to knock down all of the remaining fire that they shut down their water pipes as firefighters on the third floor are going to begin to work up there.

Firefighters continue to work on the third floor for an extended period of time and checked additional floors for any type of extension. Firefighters were able to contain the fire to one side of the apartment complex and was able to limit the amount of damage to the adjacent structure that only had siding damage. Firefighters remained on scene until the early hours of the morning conducting extensive overhaul as fire investigators worked to determine the cause of the fire. Numerous occupants of the structure were displaced along with their pets. Only one person was evaluated on scene for injuries sustained from the fire and was released from the scene without transport to the hospital. No firefighters were injured while battling the fire. The cause of the fire was determined to be from a discarded cigarette on the porch.
