Loi Le Meur Explained: What the 2024 Law Changed

Loi Le Meur, dated 19 November 2024, aimed to bring short-term letting under clearer control in France, particularly in housing-pressured cities, by generalising registration, reducing principal-residence caps in Paris, Lyon, Bordeaux and Nice from 120 to 90 nights, and setting fines of 10,000 to 50,000 EUR for breaches. Its logic was housing supply: homes let short-term for much of the year are homes unavailable for longer-term residents, so registration makes letting visible and caps limit its scale for principal residences.

The law works through existing French machinery rather than inventing a wholly new system. Commune declarations, the Declaloc number, platform checks and commune enforcement all predate or accompany the law in some form. Loi Le Meur strengthened and generalised them, so hosts who had already declared in a city with a scheme felt less change than hosts in communes where registration became newly central. That uneven experience is normal for a generalising law.

Before generalisation, registration practice varied by commune, with some cities requiring declaration and others less active. Loi Le Meur generalised registration nationwide, so hosts can no longer assume that a small commune has no declaration step. The practical change for many hosts was therefore a new administrative task: declare the property, receive the 13-digit Declaloc number, and display it. Hosts who had never declared because their commune had not pressed the point needed to catch up, and platforms began asking for numbers more consistently.

Generalisation also changed the conversation with platforms. A host without a number could previously list in some places with little friction; after generalisation and the EU display timetable, with mandatory display from 20 May 2026, a missing number became a visible gap on the listing itself. Hosts should treat the number as a listing requirement, not as a back-office reference.

Cutting principal-residence caps from 120 to 90 nights in Paris, Lyon, Bordeaux and Nice reduced by a quarter the nights a principal-residence host can let in those cities. For a host who let close to the old cap, that cut directly reduces income unless the letting pattern changes, for example by letting at higher rates for fewer nights or by shifting to longer stays outside short-let scope where lawful. For a host who let far below the cap, the cut changes little in practice but still changes the tracker target.

The cut applies to principal residences in those four cities, not to every French property and not to second homes under the same rule. Second homes follow change-of-use and commune rules instead. A host with a principal residence in Paris and a second home elsewhere must therefore track two different regimes, not one cap applied twice. Keep a separate note per property stating which regime applies and why.

Fines of 10,000 to 50,000 EUR under loi Le Meur cover breaches such as unregistered letting, missing display and cap breaches, with the scale reflecting seriousness and repetition. Hosts should not treat the range as a tariff: the actual outcome depends on the breach, the commune process and the facts. The range's real message is that these are not minor administrative penalties. A host who weighs a fine as a cost of doing business misunderstands both the scale and the reputational and platform consequences that can follow.

Platform consequences often arrive before a fine. A listing without a valid number can be suspended, and repeated suspensions can affect account standing. Commune action can also include orders affecting the letting itself, not only a payment. The cheapest compliance strategy remains the obvious one: register, display, track the cap, and keep records.

The law did not abolish condo rules, lease clauses, tax duties or energy obligations, and it did not grant second-home authorisation where change-of-use rules require it. A host who complies with loi Le Meur registration but breaches condo rules still faces private enforcement. A host who displays a number but lets a principal residence beyond 90 nights in Paris still breaches the cap. Registration is a necessary layer, not a sufficient one.

The law also did not set a single French tax rate or a single energy standard for short lets. Those topics follow their own codes and timetables, covered in general terms elsewhere in this cluster. Hosts should keep loi Le Meur compliance, tax compliance and building compliance as separate checklists, even though they share the same stay records.

Loi Le Meur implementation continues through commune procedures, platform updates and guidance, so hosts should recheck service-public.fr and the commune portal before each season. Note the date of each check, since a procedure that was optional in practice last year may be enforced strictly this year. This guide is general information only, last verified on 26 October 2026, and readers should verify the current commune steps for their property before acting.
