Declaring a furnished tourist rental is not a secondary formality: it is the legal foundation of any holiday-letting activity. Without a valid declaration and a registration number, a listing is in breach of the law, whatever the quality of the property or the platform used.
In 2026, this obligation changes scale. The generalisation of a national online service (téléservice) to all communes unifies a procedure that has so far been uneven, with a target implementation around 20 May 2026. For owners, this is both a simplification and a tightening of control.
This guide explains what the furnished tourist rental declaration is, how the 13-digit registration number works, and what the shift to the national online service means in practice.
What the furnished tourist rental declaration is
A furnished tourist rental (meublé de tourisme) is a furnished dwelling offered for hire to transient guests, for short stays, without them taking up residence. As soon as an owner lets a property in this way, it must be declared to the commune.
This declaration serves several purposes: enabling the commune to know and frame the supply of furnished rentals in its territory, ensuring the collection of the tourist tax, and guaranteeing the traceability of listings published online. It fits within a regulatory framework strengthened by recent developments, notably the Le Meur Law.
The declaration is not a mere administrative registration: it conditions the very right to publish a listing.
The 13-digit registration number
On completing the declaration through the mairie's online service, the owner is assigned a 13-digit registration number. This number is the official identifier of the furnished tourist rental.
Its role is central: it must appear on all listings, whatever the platform. A listing lacking this number, or displaying an incorrect one, exposes the owner to penalties and to possible removal of the listing by the platform.
In practice, this number links the dwelling, the declaring owner and the commune. In the event of a check, it allows the authorities to verify that the let property is indeed declared and that local regulation, nights caps, tourist tax, any restrictions, is respected.
The national online service: what changes in 2026
Until now, the declaration was made commune by commune, with varying procedures and platforms. This inconsistency sometimes made the process complex, particularly for owners holding properties in several communes.
The generalisation of a national online service aims to unify this process. The objective is to offer a harmonised entry point for all communes, with a target implementation around 20 May 2026.
For owners, this change has several consequences:
- A clearer procedure, with a common framework regardless of where the property is located.
- Reinforced control, as centralisation makes it easier to cross-reference data between communes, platforms and administration.
- Higher compliance requirements, since the traceability of listings is improved.
In short, the declaration becomes simpler to complete but harder to circumvent. This is good news for rigorous owners, and a heightened risk for those who let their obligations drift.
The key steps of a compliant declaration
A well-conducted declaration follows a simple logic, best respected in order.
- Check the property's eligibility, notably ensuring the co-ownership regulations authorise furnished tourist rental.
- Gather the necessary information: owner's identity, precise address of the dwelling, characteristics, guest capacity.
- Complete the declaration through the commune's online service, then, as it is generalised, through the national online service.
- Retrieve the 13-digit registration number issued at the end of the process.
- Display this number on every listing, on all platforms.
- Keep the declaration up to date in the event of a change of circumstances or evolving local regulation.
This discipline, seemingly administrative, protects the owner and secures the entire operation.

Why delegate declarative compliance
The declaration is not an isolated act: it sits within a set of shifting obligations, spanning nights caps, tourist tax, co-ownership rules and energy requirements. Following these developments, keeping declarations up to date and ensuring the registration number appears on every listing demands continuous attention.
This is precisely the role of a professional operator. At Serava, declarative compliance is an integral part of management. Each property is administered under a mandate compliant with the loi Hoguet, backed by a professional card CPI 67012023000000016 and a SOCAF financial guarantee of €150,000. The owner retains full visibility through their real-time portal, where every reservation, every statement and every euro is instantly accessible.
Delegating is not disengaging: it means entrusting these obligations to an organisation whose profession this is, while keeping control of what matters.
