Overview
- The blaze was reported midmorning on Friday and escalated to a third‑alarm after firefighters saw heavy flames through the roof.
- Fire units from Riverside city and county, Ontario, San Bernardino and Cal Fire used water‑tower operations and mutual aid to contain the fire and protect nearby structures.
- Officials say roughly 50 of the building’s 112 units were affected and about 115 people were displaced, with all residents evacuated and no injuries reported.
- The cause remains undetermined because crews have not allowed investigators inside the unstable structure, and fire officials warned the garden‑style design and continuous attic voids helped the fire spread.
- Reports vary on the complex’s name and address in early coverage, and UCR is working to identify and support any students who were displaced while the Red Cross assists evacuees.
