Janitors are cleaners. Typically the people who maintain apartments are called maintenance workers, handymen, or (old fashioned) superintendent. Sometimes property manager, if they also handle renting it out.
Janitors are only employed in large, expensive apartment buildings. Single family homes don’t use them, nor do cheaper apartments. So that’s not really descriptive of a landlords job at all.
Owning a property is not a job but maintaining one can be. If you don’t own the property then that’d just be called being a janitor.
