A two alarm commercial structure fire broke out in Santa Ana at 1441 E. 17th St. last night at 11:30 p.m.

The structure that burned has been vacant for some time. The neighbors have often complained about homeless people hanging out at that building.

Approximately 60 firefighters fought heavy fire upon arrival and maximized the hydrants to supply the multiple ladder pipes and large hand lines.

They were engaged in a defensive attack on the blaze. Initial crews had spotted fire coming through the roof.

The OCFA was assisted by firefighters from the Orange Fire Department and the SAPD.

OCFA fire investigators continue their detailed work. They were using drones to assist in finding hot spots.

The OCFA was also assisted by the Santa Ana Building Dept. and the Water Dept. for all their much appreciated assistance.
