2013-present: ICSM elementary building fire, reconstruction, present history
In 2013, the neighboring building of the Immaculate Conception School of Malolos whom then situated the Elementary Department until 2015 when Late Bishop Jose Oliveros D.D. established the Senior High School Department, caught on fire in the middle of the night. People crowded outside the building to watch the damage in the fire. In the same year, the fire was declared to be an exposed wiring situation. It wasn't until 2017 when the elementary building got finished, 4 years after the fire occurred. The size of the building was reduced as the present building of the ICSB branch is smaller than the original that burnt. Two segments of the building were demolished due to permanent destruction. As of today, the building stands firm and both buildings of ICSB and ICSM are now built with stone.

The Immaculate Conception School for Boys is always headed by the Bishop of Malolos. The satellite branches of the school also operate under the presidency of the Bishop.
