Cold-storage giant Lineage has filed a more than $1 billion lawsuit against Altus Power and Pearce Services, alleging that problems with a rooftop solar system led to the devastating June 17 fire at its 500,000-square-foot warehouse in Boyle Heights, Los Angeles.
The lawsuit, filed in Los Angeles County Superior Court, accuses Altus Power, the solar-array operator, and Pearce Services, its contractor, of negligence, safety violations and breach of contract.
Lineage alleges the companies re-energized the rooftop solar system despite warnings that additional safety checks were needed.
Why Is Lineage Suing Altus Power?
According to the complaint, Lineage had raised concerns about the solar array after an earlier fire occurred on the warehouse roof in August 2024.
The company claims inspections later identified more than 200 connector failures and other electrical problems.
Lineage alleges Pearce crews were performing testing on the solar installation when the June 17 fire began.
The company says it had requested additional voltage checks and other safety procedures before the system was energized.
The lawsuit claims those warnings were disregarded.
What Happened in the Boyle Heights Fire?
The blaze proved exceptionally difficult to extinguish.
The Los Angeles Fire Department said the fire was brought under control on June 24 after days of firefighting operations involving a heavily damaged cold-storage structure.
The disaster also created a major cleanup crisis.
Millions of pounds of food spoiled after the facility lost refrigeration, producing severe odors and attracting pests in surrounding neighborhoods. Lineage has said the cleanup cost more than $100 million.

What Do Altus Power and Pearce Say?
Altus disputes Lineageβs allegations and has characterized the lawsuit as an attempt to shift responsibility. The company says it takes safety seriously and intends to contest the claims.
Pearce has also disputed premature conclusions, emphasizing that the investigation into the fireβs origin and cause remains ongoing.
That distinction is important: Lineageβs allegations have not been proven in court, and authorities have not publicly established that the solar array caused the fire.
Why the Lawsuit Could Matter
The case arrives as California continues expanding commercial rooftop solar installations, including on large industrial buildings.
It could therefore become an important legal test over responsibility for solar equipment, maintenance, electrical contractors and fire-related losses.
For now, the central question remains unresolved: Did a defective or improperly serviced solar array ignite the Boyle Heights warehouse fire, or did another factor cause the disaster?
The answer could determine whether Lineage ultimately recovers damages, and who bears responsibility for one of Los Angelesβ most consequential industrial fires of 2026.
