The Fresno Fire Department says it started just before 6 a.m. Firefighters say a manager started a deep fryer in the morning. About 30 minutes later it caught fire.
All employees were outside of the building when firefighters arrived.
The sprinkler system was activated and kept the fire from spreading, but there was lot of water in the building, according to officials.
The Department of Public Health will assess the damage and determine when the Chipotle can reopen.
