Ricker said the Fire Department will recommend to Palmdale’s building inspectors that the building be condemned due to severe structural damage. “It will have to be completely rebuilt,” Ricker said. Both Antelope Valley ladder trucks responded to the scene. Firefighters had most of the blaze extinguished within 45 minutes, and had all secondary fires out in about an hour. Fire Inspector Jason Hurd said firefighters engaged in potentially dangerous work, discovering and extinguishing hidden fires behind walls. El Pollo Loco spokeswoman Julie Weeks said her company was working with Fire Department investigators to determine the precise cause of the fire. She said it was too soon for the company to comment on whether the restaurant will be rebuilt.

PALMDALE – Investigators ruled out arson as the cause of a fire Friday morning that destroyed a Palmdale fast-food restaurant, a fire department official said. Los Angeles County fire Capt. Michael Ricker said the fire at the El Pollo Loco on 22nd Street East and Palmdale Boulevard started inside a wall adjacent to a grill. Nobody was injured in the blaze, reported at 5:50 a.m. Ricker said the fire was likely caused by radiant heat from the grill and other kitchen equipment. He said protective insulation decomposed over time – the restaurant is 18 years old.
