Out of Order (OOO)
Out of Order (OOO) is a room status designation in hotel operations indicating that a specific room or unit is physically unavailable for sale. A room is placed in OOO status due to maintenance work, refurbishment, structural damage, or a similar issue that makes it uninhabitable or unsafe. Unlike "Out of Service" — which typically denotes a minor issue where a room may still be assignable in an emergency — an OOO room is fully removed from sellable inventory in the PMS and cannot be booked or assigned to guests.
Why it matters
OOO rooms directly reduce a property's available inventory, which flows into every key performance metric:
- Occupancy Rate is calculated against available (non-OOO) rooms, so a high OOO count can artificially inflate reported occupancy without reflecting genuine commercial performance.
- RevPAR and NRevPAR are similarly affected, since the denominator (available rooms) shrinks.
- Revenue forecasting must account for OOO inventory when projecting capacity, particularly if rooms are offline during peak demand periods.
Inaccurate OOO tracking can lead to overbooking situations, guest walk incidents, and disputes with OTAs over inventory availability. Revenue managers typically review OOO counts in their daily operations briefing alongside pickup and pace data.
Most PMSes distinguish OOO from Out of Service (OOS) in reporting, ensuring that rooms pulled for deep renovation or major repair do not distort short-term operational metrics.
