Housekeeping covers guest room cleaning, public area maintenance, and laundry/linen management, all guided by checklists that ensure consistency regardless of who is on shift. Hotels track room readiness using standard status codes such as vacant clean, vacant dirty, occupied clean, occupied dirty, and out of order, which front office staff rely on to know which rooms can be sold or assigned next. Many properties now build sustainability into housekeeping through linen and towel reuse programs that let guests opt out of daily changes, reducing water and energy use from laundering.
