A custodian and a janitor are necessary for cleaning and maintaining buildings, although their scope of duties varies. A custodian is in charge of the facility’s security, cleaning, and general upkeep. They are in charge of duties including sweeping floors, cleaning bathrooms, and maintaining the general operation and safety of the building. On the other hand, a janitor is primarily concerned with cleaning tasks, including sweeping, dusting, and emptying garbage cans. Janitors only focus on maintaining the property’s cleanliness and orderliness, whereas custodians supervise the facility’s overall operations. Both tasks are essential to provide residents with a clean and safe environment.
