Luxembourg short-term rental regulation and SDEP status

What this means

Luxembourg treats transient/tourist accommodation as a regulated accommodation-establishment activity when the operator crosses the relevant operating threshold.

Guichet.lu states that accommodation-establishment operators rent accommodation units and cross the commercial threshold at 90 overnight stays or more accumulated over a year.

Since 1 September 2025, tourist accommodation operators must record a traveller accommodation form for every stay and every guest aged 15 or over in a public electronic system.

Implementation status

Operators at the threshold need a business permit, and a breakdown of overnight stays must be drawn up for each accommodation unit.

The law of 28 February 2025 on accommodation forms entered into force on 1 September 2025 and applies to any operator providing tourist accommodation in return for payment, including short-term accommodation.

Operators must declare each tourist accommodation establishment with STATEC and request access to the electronic accommodation-form system; STATEC verifies the operator and assigns a unique identification number.

Guichet.lu separately explains that short-term furnished residential letting can trigger hotel/private tourist establishment rules and guest-form communication to the police.

Technical interface

Public online services exist for business-permit and traveller-form processes.

Traveller data can be collected through the Lux Héberge app, pre-fill links, a MyGuichet.lu business eSpace, or a web-service connection for booking software, where the operator bears the cost of adapting its software.

No Luxembourg-specific SDEP OpenAPI documentation, source code, sandbox, registration-number validation API, or platform onboarding process is currently available.

A future implementation may need to connect accommodation-establishment status, guest forms, and any STR-specific registration procedure.
