Los Angeles Investigates Alleged Unpermitted Construction at Warehouse Following Massive Fire

The Los Angeles Department of Building and Safety has launched an investigation into alleged unpermitted construction at a 500,000-square-foot cold storage warehouse in Boyle Heights following a massive eight-day fire. The blaze, which primarily involved a rooftop solar array, prompted a state of emergency declaration and raised significant concerns regarding building code compliance and safety oversight. This investigation highlights the critical importance of permit adherence and rigorous inspections for large-scale industrial facilities, particularly those integrating complex renewable energy systems.

The investigation focuses on whether repairs following a previous August 2024 fire at the same facility were conducted without the necessary permits or inspections. While a permit for the original rooftop solar system was issued in July 2020 to building owner Chill Build Los Angeles I, LLC, city records show no subsequent permits or inspections for repairs after the 2024 incident, which reportedly cost the logistics operator, Lineage, approximately $6 million. A source familiar with the matter noted that the lack of follow-up inspections suggests that lessons from the initial fire may not have been implemented, leading to the more recent, stubborn blaze that required over a week to extinguish.

Responsibility for the rooftop infrastructure is currently a point of contention between the involved parties. Lineage, the world’s largest owner of cold storage facilities, stated that the fire likely began while Altus Power—the owner of the solar array through its subsidiary Los Palos Street Operating, LLC—was conducting tests. Altus Power is responsible for the design, installation, and maintenance of the system, while the solar contractor is Pearce, a subsidiary of CBRE. Both Lineage and Pearce are now under inspection by the California Division of Occupational Safety and Health (Cal/OSHA) as authorities seek to determine the exact cause and whether safety protocols were breached.

The scale of the incident necessitated a state of emergency declaration by Governor Gavin Newsom and Mayor Karen Bass due to health hazards from smoke and the presence of hazardous materials. Precautionary measures included the removal of ammonia used in the warehouse's refrigeration systems to prevent further environmental risk. This event underscores the broader risks associated with industrial warehouse management, as Lineage has faced similar scrutiny over a 2024 warehouse fire in Finley, Washington, which burned for two months and led to health-related lawsuits. For the construction and building sector, the case serves as a stark reminder of the legal and safety liabilities inherent in unpermitted modifications to large-scale commercial structures.
