Portland Authorities Address Centennial Mills Fire Aftermath and Demolition Plans
A significant fire broke out at the Centennial Mills building in Portland on August 2, 2026, prompting a response from nearly 100 firefighters. The fire, which escalated to a four-alarm incident, resulted in the collapse of each floor of the 116-year-old warehouse. Due to the structural damage and instability, there is a risk of the building collapsing. Portland Fire & Rescue has established a safety perimeter to protect public health and safety. The City of Portland is working with the property owner to manage the demolition of the building safely. The Portland Permitting & Development department has issued a Notification of Dangerous Structure and Order to Demolish, requiring immediate action to disconnect utilities, maintain a collapse hazard perimeter, and begin demolition by August 14. Air quality monitoring is ongoing, with preliminary results indicating low health risks from debris and air contaminants.
