Late on the night of February 21, 2025, the Lynn, MA Fire Alarm Office dispatched units to a reported building fire on Estes Street. Upon arrival, Engine 5 found smoke showing from the second floor of a three-story occupied multiple dwelling (OMD) located behind other structures, set well off the street. They immediately called for a working fire assignment.

As crews began their interior attack, command noted that strong winds were pushing the fire toward an exposure—a large 2.5-story church on Chestnut Street. With conditions worsening, a second alarm was struck, bringing the remaining Lynn companies to the scene and calling in mutual aid for citywide coverage.

While interior crews aggressively fought the fire in the original structure, second-alarm companies worked to protect the church. However, reports soon came in that fire had extended into the walls and was breaking through the roof of the primary building. Structural integrity became a concern, and command ordered a transition to defensive operations. A third alarm was sounded, summoning additional mutual aid, including engines from Saugus, Swampscott, and Melrose, along with a ladder from Revere.

Master streams were deployed, with ladder pipes and a deck gun put into action to battle the fire in both the original building and the now fully involved exposure on Chestnut Street. As flames spread, a fourth alarm was struck, bringing in engines from Salem, Marblehead, and Peabody, along with a Swampscott ladder. With more exposures at risk, additional evacuations were conducted, prompting a fifth alarm. Revere and Lynnfield engines, as well as a Chelsea ladder, were added to the response.

During the height of the operations, the second floor of the first exposure building failed, leading to a collapse of the alpha side. Fortunately, there were no injuries. Firefighters remained on scene well into the morning of February 22, continuing defensive operations and overhaul.

Later that day, the rubble pile from the collapsed structure reignited. A working fire assignment was dispatched to extinguish the rekindled flames, ensuring the fire was fully knocked down.
