The fire, the repeat, and who's involved
A June 17, 2026 fire at the Lineage cold-storage warehouse at 1400 S. Los Palos Street sent smoke across the neighborhood for days. Here's the sourced account.
The fire
The fire involved the building's rooftop solar panels, and an ammonia refrigeration line was damaged in the blaze. Roughly 85 million pounds of frozen food were inside. It burned for days. A wind shift even caused a reignition, and shelter-in-place orders were issued and lifted more than once. No injuries were reported. The official cause is still under investigation.
Timeline
- 2018: the 479,000 sq-ft cold-storage building is built.
- 2020: a small ammonia release at the site; a Cal/OSHA process-safety inspection follows.
- Aug 14, 2024: the rooftop solar catches fire; firefighters knock it down in ~48 minutes.
- Jun 17, 2026: the major fire begins on the roof; the ammonia line is compromised.
- Jun 20, 2026: City and State emergencies declared.
- Jun 23, 2026: LA County directs an investigation and "recompense" from the operator (Item 11-B).
This wasn't the first time
The single most important fact: the same rooftop caught fire on August 14, 2024. So the fair question is simple. After that fire, did anyone inspect or fix the rooftop solar? The city's public building-permit records show no permit for repairing or replacing the rooftop solar system in the nearly two years between the fires. (A missing permit doesn't prove no work was done, but the public record shows none.) The deeper inspection records are held by the Fire Department and are currently withheld.
There's also a documented safety history at this site: in 2020, Cal/OSHA's process-safety unit inspected the facility (ammonia emphasis) and initially issued 12 citations, 4 of them serious, including failure to maintain an emergency action plan and to train emergency responders. confirmed In fairness, the company contested, a judge later deleted most of the citations, and the final outcome was 3 minor violations and a $2,200 penalty. Both the initial citations and the reduced final result are public record.
What's stored there, and why the location matters
This refrigerated warehouse uses anhydrous ammonia (a toxic, corrosive gas) to keep food frozen. Its own federal safety filing lists up to about 12,300 pounds of it. The building is about 479,000 sq ft, built in 2018.
And the location matters: California's environmental-screening tool ranks this spot in the highest tier (90th to 100th percentile) for pollution burden. A neighborhood already carrying more than its share of industrial pollution is exactly why a hazard like this deserves a higher standard of care.
Who's responsible
Several parties are involved and already pointing at each other; the official cause is still under investigation and nobody has been found at fault.
- Lineage operates the warehouse and the ammonia system; it says it's only the tenant.
- The rooftop solar is owned by Los Palos Street Operating, LLC (an Altus Power company). Lineage blamed Altus's contractor's "testing"; Altus disputes that. reported
- The solar contractor was Pearce (part of CBRE). reported
- The building is reported owned by Chill Build Los Angeles I, LLC. reported
The point isn't to pick a villain. The question that matters is who was responsible for that rooftop equipment, and whether it was ever fixed after 2024.
