Room Status Codes

Room status codes are standardized abbreviations used by hotel housekeeping and front desk departments to communicate the current occupancy and cleanliness condition of every guest room in real time. Each code combines two pieces of information — whether a room is occupied or vacant, and whether it is clean or dirty — into a single shorthand designation that drives room assignments, cleaning priorities, and maintenance scheduling across the property.

Core Room Status Codes

The most widely used codes across US hotel operations fall into three categories: occupancy state, cleanliness state, and exception state. Understanding what each code means — and the difference between similar-sounding codes — is essential for preventing costly operational errors like double-assignment.

OCC — Occupied: A registered guest is currently staying in the room.
V — Vacant: No guest is currently assigned to the room.
VD — Vacant and Dirty: Guest has checked out; room has not yet been cleaned. The room cannot be sold.
VC — Vacant and Clean: Room attendant has completed the clean, but a supervisor has not yet inspected it. Still not ready for assignment in full-service properties.
VR / VCI — Vacant Ready / Vacant Cleaned and Inspected: Room has been cleaned and verified by a housekeeping supervisor. This is the only status from which a room should be assigned to a new arriving guest.
OC — Occupied and Clean: In-house guest’s room has been serviced.
OD — Occupied and Dirty: In-house guest’s room has not yet been serviced for the day.
OOO — Out of Order: Room has a serious problem (burst pipe, major renovation) and is fully removed from hotel inventory. Cannot be sold under any circumstances; affects occupancy percentage calculations.
OOS — Out of Service: Room is temporarily unavailable for a minor issue. Unlike OOO, an OOS room is not deducted from the hotel’s official room count and can return to sellable inventory quickly.
DND — Do Not Disturb: Guest has declined housekeeping service, typically communicated via a Do Not Disturb sign or door hanger.
On-Queue: Guest has arrived at the property, but their assigned room is not yet ready. Housekeeping is directed to prioritize that room immediately.
CO — Check-Out: Guest has vacated; room needs preparation for the next arrival.
DNCO — Did Not Check Out: Guest settled their bill but never formally checked out at the front desk. The room appears occupied in the system but may be vacant, requiring physical verification before cleaning can begin.
SO — Slept Out: Room is occupied on paper but the bed was unused, suggesting the guest slept elsewhere.
NS — No Show: A reservation was made but the guest never arrived.
HU — House Use: Room is occupied by hotel staff.

The Room Status Lifecycle

Room status follows a predictable sequence throughout the day: a room moves from OCC → OD (after the in-house guest wakes) → VD (after checkout) → VC (after the room attendant completes the clean) → VCI/VR (after supervisor inspection) → OCC (after the next guest checks in and receives a key card). Understanding this flow helps housekeeping supervisors sequence their floor assignments and helps front desk agents manage guest expectations during peak check-in hours.

The room attendant executes the physical steps that drive most of these transitions. Using a room attendant cart stocked with fresh linens and supplies, attendants move through VD rooms, collect soiled linens in a linen bag, dispatch them via a laundry chute or soil cart, and clean the room using tools like a room attendant caddy and microfiber cloths before updating the status to VC.

OOO vs. OOS: A Critical Distinction

Confusing Out of Order and Out of Service creates real financial consequences. An OOO room is fully removed from the sellable inventory count — if a 200-room hotel has 5 rooms OOO, it is operating as a 195-room hotel for purposes of occupancy and RevPAR calculations. An OOS room remains in the inventory count but is temporarily blocked; it does not affect the denominator in occupancy metrics. Engineering and maintenance teams monitor both statuses to schedule repairs, and a deep clean is a common reason a room moves to OOS temporarily.

Room Status Reconciliation

Room status reconciliation is the process of ensuring every room is correctly labeled and updated as conditions change throughout the day. It is the primary mechanism a hotel uses to prevent double-assignment — assigning two guests to the same room — and to maximize room revenue by releasing cleaned rooms to the front desk as quickly as possible. Discrepancies between what housekeeping reports and what the front desk sees in the system are a common failure point that leads to guest complaints and comp nights.

How Room Status Is Managed Today

Modern hotels use Property Management System (PMS) software — such as Oracle Opera or Cloudbeds — integrated with mobile devices carried by room attendants and supervisors. Status updates happen in real time: when an attendant finishes a room, they update the PMS from their handheld, and the front desk sees the change instantly. Some PMS platforms support up to 10 customizable housekeeping status codes, allowing properties to configure codes that match their specific service model. Older or non-automated properties rely on manual telephone PBX codes or logbook entries, which introduce lag time and reconciliation errors.

Room Status and Sustainability

Room status codes directly enable opt-in green housekeeping programs. When a guest selects DND or a “Service Refused” (SR) status for a stayover night, housekeeping skips the room — reducing linen and terry laundering, water consumption, and chemical use. These practices align with green lodging certification criteria such as Green Key and LEED, and they directly affect linen par and terry PAR calculations. Accurate OOO tracking also supports energy management: rooms removed from inventory can have HVAC and lighting systems scaled back, lowering the property’s overall energy footprint.

Common Uses

Department & Usage: Room status codes are used jointly by three hotel departments. The Front Office uses codes — particularly VR/VCI — to determine which rooms can be assigned to arriving guests and to manage On-Queue situations when guests arrive before their room is ready. The Housekeeping department uses codes to sequence cleaning assignments, prioritize On-Queue and early-arrival rooms, and flag rooms for supervisor inspection before releasing them to the front desk. Engineering and Maintenance monitor OOO and OOS codes to schedule repairs and ensure rooms are returned to sellable inventory as quickly as possible. In daily operations, status codes are updated continuously — from the moment a guest checks out (VD) through cleaning (VC) and inspection (VCI) to the next check-in (OCC) — forming the operational backbone of room inventory management.

Sustainability

Room status codes directly support hotel sustainability programs by enabling opt-in housekeeping service models. When guests select Do Not Disturb (DND) or a Service Refused (SR) status during a stayover, housekeeping skips the room, reducing linen and terry laundering frequency, water use, and cleaning chemical consumption. These practices are recognized criteria under green lodging certifications including Green Key and LEED for Existing Buildings. Stayover and DND statuses also reduce daily linen par and terry PAR consumption, which lowers laundry labor and utility costs. Accurate Out of Order (OOO) tracking supports energy management: rooms removed from inventory can have HVAC, lighting, and other systems reduced or shut off, meaningfully lowering a property's overall energy footprint during low-occupancy periods or extended renovations.

Frequently Asked Questions

VC means the room has been cleaned by a room attendant but has not yet been inspected by a housekeeping supervisor. VR or VCI means the room has been both cleaned and verified by a supervisor — this is the only status from which a room should be assigned to a new arriving guest in full-service hotel operations.

OOO indicates a serious problem — such as a burst pipe or major renovation — that fully removes the room from hotel inventory. It cannot be sold and is deducted from the hotel's room count for occupancy calculations. OOS is a temporary, minor issue; the room is not currently sellable but is not removed from the official room count and can be returned to service quickly without affecting occupancy metrics.

Room status reconciliation is the process of ensuring every room in the hotel is correctly labeled with its current status and updated as conditions change throughout the day. It is the primary mechanism hotels use to prevent double-assignment, manage room availability, and maximize room revenue by releasing cleaned and inspected rooms to the front desk as efficiently as possible.

On-Queue status is assigned when a guest has physically arrived at the hotel but their designated room is not yet cleaned and ready. It signals housekeeping to prioritize cleaning that room before others so the waiting guest can be checked in as quickly as possible.

DNCO (Did Not Check Out) means a guest settled their bill but never formally checked out at the front desk. The room may appear occupied in the PMS but could actually be vacant. Housekeeping must physically verify the room's condition before cleaning can begin and the room can be returned to sellable inventory.

Modern hotels use PMS platforms such as Oracle Opera or Cloudbeds integrated with mobile devices carried by room attendants and supervisors. Status updates are made in real time on handheld devices and are instantly visible to all departments. Older or non-automated properties rely on telephone PBX codes or manual logbook entries, which introduce lag and increase the risk of reconciliation errors.

Yes. While core codes — VC, VD, VR, OCC, OOO, DND — are industry-standard conventions established through hospitality management curricula and PMS platforms, some systems allow properties to configure up to 10 custom housekeeping status codes to fit their specific operational workflows and service models.
