The duties of a doorman will vary depending on the type of establishment, area, size of building and shift. Hotels in larger cities employ doormen around the clock. In the winter, the doorman may be responsible for keeping the entrance and sidewalk clear of ice and snow. Many doormen also tidy up around the lobby, monitor security cameras, keep logs of package deliveries and open taxi doors for residents. A doorman in a co-op or condo will get to know the residents and make note of any visitors that come by when the residents are away.
