“Before my first rental, what do I have to declare, and where?” That’s the very first thing an owner asks me before listing their property online. Declaring a short-term rental in Martinique is nothing to be afraid of, but it’s changing in 2026 with the arrival of a single national online service. As a concierge company based on the island, we put these files together every day, from Fort-de-France to Sainte-Anne. Here’s how to do it, step by step, with the specific points to watch for in France’s overseas departments and regions (DROM).
Why declaring your tourist rental is mandatory
Martinique is a French overseas department (DROM): the Tourism Code applies there exactly as it does in mainland France. Anyone offering a furnished tourist rental — a furnished home rented to passing guests who do not make it their permanent residence, for a maximum of 90 consecutive days per guest — must declare it to their town hall. This isn’t optional, and it doesn’t depend on the platform you use.
Two situations to distinguish from the outset:
- Your main residence (which you occupy at least 8 months a year): you may rent it short-term for a maximum of 120 days per year.
- A second home or a rental investment: no day cap, but stricter rules, including the possible change-of-use authorization in the most strained towns such as Fort-de-France.
In both cases, the declaration is the mandatory foundation. It’s what makes your activity legal and what reassures the traveler: a declared home is a controlled, insured home held to safety standards.
The registration number: what changes in 2026
Until now, only certain tourist towns required an online declaration generating a registration number to display on listings. That landscape is being dramatically simplified.
The new national “Declaloc” online service
The law of 19 November 2024 (known as the “Le Meur law”) establishes a single national registration system for short-term rentals. In practice, an online service called Declaloc (declaloc.fr) must be fully operational by 20 May 2026 at the latest. It replaces the patchwork of local procedures with a single online portal.
What this changes for you, an owner in Martinique:
- Registration becomes mandatory in every town, not just in big cities or strained areas.
- It applies to all tourist rentals, whether a main residence or a second home, held in your own name or through a company.
- Once the declaration is complete, the online service issues a 13-character alphanumeric registration number.
- This number must appear on each of your listings (Airbnb, Booking, personal website). Without it, the platform may remove the listing.
Good news for those already compliant: registration numbers already issued by the towns remain valid during the transition. If you already rent in a town that applied online declaration, you don’t have to start from scratch overnight.
Why this reform particularly affects the overseas territories
This is where Airbnb regulation in Martinique takes on a local flavor. Housing pressure is intense in the overseas territories, where tourist demand sits alongside a limited housing stock. Making registration universal gives Martinique’s town halls a monitoring tool they didn’t always have. Anticipating means avoiding finding yourself suddenly outside the law while your villa was running beautifully.
How to declare, step by step
Here is the concrete path we follow for every property we take under management.
- Check the property’s status: main residence (120-day cap) or second home (stricter rules). This conditions everything else.
- Ask the town hall about the existence of a change-of-use procedure and any potential compensation rule, especially in Fort-de-France for a second home.
- Gather the supporting documents (see the list below).
- Submit the declaration online through the national service, or via your town hall’s portal until Declaloc takes over. For a second home in a town without online declaration, the Cerfa form no. 14004 remains the classic route.
- Retrieve the registration number issued automatically.
- Display this number on all your listings, without exception.
- Keep the acknowledgment of receipt: a municipal inspection can occur, and a complete file keeps you covered.
The documents to prepare
Before getting started, gather:
- a proof of identity (or a Kbis extract if you rent through a company);
- a proof of ownership or occupancy: title deed, recent property tax notice, or the landlord’s written authorization if you are a tenant;
- the change-of-use authorization if your town requires it;
- a valid energy performance certificate (DPE). Since 20 November 2024, new changes of use toward tourist rental require a DPE rated between A and E; energy-inefficient homes (F and G) are gradually excluded.
The declaration itself now takes a few minutes from home. It’s preparing the documents — especially the DPE and any change of use — that calls for planning ahead.
How much it costs, and what you risk by forgetting
Declaring at the town hall is free: neither the town nor the online service charges for registration. Your real incidental costs are the DPE (budget 120 to 250 € depending on the surface area, with an assessor traveling across the island) and, where applicable, tourist rating classification (in the range of 150 to 300 € for the visit of an approved body), optional but tax-advantageous.
On the penalty side, the Le Meur law sharply raised the bar:
- failure to declare: a fine of up to 10,000 €;
- false declaration: up to 20,000 €;
- exceeding the 120-day cap for a main residence: a fine of up to 15,000 €.
Suffice it to say that, in light of these amounts, free registration and a few hundred euros of DPE are a no-brainer. A single listing without a number is enough to draw attention.
Tourist tax, the inseparable complement
Declaring your rental and collecting the tourist tax in Fort-de-France as in any tourist town go hand in hand. This tax is paid by the traveler, not by you: you (or the platform via agreement) collect it and remit it to the town. In Martinique, an additional departmental tax of 10% is added to the municipal rate and appears directly on the traveler’s invoice. Once your home is registered, remember to set up the collection correctly to avoid double billing.
Book and rent compliantly with Hostel Toucan

Declaration isn’t an obstacle: done well, it turns a home into a lasting and perfectly serene source of income, even from a distance.
FAQ
Is it mandatory to declare a short-term rental in Martinique?
Yes. Any furnished tourist rental let to passing guests must be declared at the town hall, whether it’s your main residence or a second home. This obligation applies across all of French territory, including the overseas departments. From 20 May 2026, the declaration goes through the national Declaloc online service and generates a registration number to display on your listings.
How do I obtain a registration number for my rental in Martinique?
You complete the declaration online on the national service (or your town hall’s portal during the transition), providing a proof of identity, a proof of ownership or occupancy, a valid DPE and, if necessary, the change-of-use authorization. The 13-character registration number is issued to you immediately and must appear on each of your listings.
What penalties apply for an undeclared rental in Martinique?
Since the Le Meur law of 19 November 2024, failure to declare is punishable by a fine of up to 10,000 €, false declaration up to 20,000 €, and exceeding the 120-day cap for a main residence up to 15,000 €. A listing without a registration number can also be removed by the platform.
Does my old registration number remain valid with the new online service?
Yes, during the transition phase. Registration numbers already issued by Martinique’s towns remain valid until the national Declaloc online service is operational. So you don’t have to redo your application overnight, but in time you’ll need to switch to the national system. We track this transition for every property we manage.
