San Luis Obispo post office fire under investigation

Officials have not determined whether an early Saturday morning fire at a San Luis Obispo post office was intentionally or accidentally set.

A fire broke out around midnight at a post office in the 1600 block of Dalidio Drive, just off Madonna Road. The blaze was contained to a trash bin and had almost burned out when San Luis Obispo police officers responded and put out the remaining flames with a fire extinguisher, said Fire Marshal Rodger Maggio of the San Luis Obispo Fire Department.

The fire melted the bin and damaged a nearby tempered glass window, Maggio said. Dana Trevino, the San Luis Obispo County post master, said repairs will cost an estimated $10,000.

Trevino said the facility’s lobby remains open 24 hours, and transients sometimes take shelter inside. The fire was “human-caused,” but it’s difficult for officials to determine whether it was arson or an accident, Maggio said. Cigarettes and remnants were found around the bin and in the room, so Maggio said someone may have thrown away a lit butt.

While the window is being repaired, Trevino said the post office will lock its lobby overnight. San Luis Obispo fire officials are investigating the incident.
