A janitor, custodian, porter, cleaner or caretaker is a person who cleans and maintains buildings such as hospitals, schools, and residential accommodation. Janitors' primary responsibility is as a cleaner. Janitors typically earn an average wage of $15 per hour in the United States. That translates to an annual salary of around $35,000 for states that pay janitors the most, such as New York, Massachusetts, and Connecticut. In some cases, they will also carry out maintenance and security duties. A similar position, but usually with more managerial duties and not including cleaning, is occupied by building superintendents in the United States and site managers in schools in the United Kingdom. Cleaning is one of the most commonly outsourced services.
