Firefighters were called to the 14900 block of Summit Drive in Eastvale Sunday evening after an outside fire involving stacked pallets at a commercial building spread into the structure itself, prompting crews to request a second alarm and call in help from a neighboring department.
The fire was reported at 5:49 p.m., according to CAL FIRE/Riverside County Fire Department, which posted that firefighters were on scene of an outside fire involving pallets at a commercial building that had spread into the structure. The department requested assistance from the Ontario Fire Department as crews worked to contain the blaze, and it directed anyone with an emergency to call 9-1-1 rather than the department’s social media page, noting the page is not actively monitored for emergencies.
The address sits within The Ranch at Eastvale, a 97-acre commercial logistics park that has grown since 2016 into a hub for multi-tenant warehousing and fulfillment operations, including firms like Weber Logistics, Flex Logistics, and VSR Logistics, according to listings tracked by LoopNet. The complex is part of Eastvale’s broader transformation from dairy agricultural land into one of the Inland Empire’s major freight and distribution centers.

The National Fire Protection Association warns that the internal airflow gaps created by stacked pallets accelerate combustion and can generate peak heat release rates strong enough to overwhelm standard building sprinkler systems once flames breach a structure. Those same gaps that channel oxygen upward also shield lower layers of a pallet stack from sprinkler water, making an exterior pile difficult to knock down quickly…
