Airbnb fines in 2026: what hosts really risk (and the three clean ways out)

For a decade, short-term letting lived on an imbalance: strict rules on paper, rare inspections in practice. The law of 19 November 2024 (known as the “Le Meur law” or the “anti-Airbnb law”) closed that chapter: universal registration of short-term rentals (meublés de tourisme), a main-residence cap that can be lowered from 120 to 90 days by a simple council vote, extension of the change of use regime to far more municipalities, quotas on short-term rentals and zones reserved for main residences in local planning documents (PLU), energy-performance (DPE) requirements progressively aligned with long-term lettings, and a trimmed-down micro-BIC tax regime.

Above all, the law gave mayors what they had been missing: data (the platforms now report it), sworn inspectors, and deterrent fines. Paris, Lyon, Annecy, Biarritz and La Rochelle already have dedicated teams — and mid-sized towns are following.

• Converting a dwelling into a short-term rental without change-of-use authorisation (in municipalities that require it): a civil fine of up to €50,000 per dwelling, potentially combined with a daily penalty payment until the property is returned to residential use.
• Exceeding the day cap on a main residence (120 days, or 90 in municipalities that have lowered it): a civil fine of up to €10,000.
• Letting without a registration number, or with an inaccurate one: fines under the French tourism code, toughened by the 2024 law — plus delisting by the platforms, which now block non-compliant listings.
• False declarations (declaring a main residence that is not one, under-reporting nights): heavier sanctions, with town halls cross-checking platform data against their own records.

On top of these amounts comes the commercial risk: an operation shut down overnight, bookings to refund, and a property that becomes unsellable “with its business attached”, since that business is unlawful.

Three channels feed the inspections. The platforms first: they report night counts to municipalities and block listings without a valid number. Town halls next: sworn inspectors, cross-checking of records (housing tax, tourist tax, planning authorisations), targeted campaigns neighbourhood by neighbourhood. The neighbours last: a significant share of proceedings begins with a report from the building's co-ownership — and the co-ownership rules are themselves a separate litigation front, independent of the town hall.

The common thread: inspections come without warning. By the time the letter arrives, the operation is already exposed, and any negotiation starts from a position of weakness.

1. Come back within the housing rules. Main residence within the local cap, or medium-term letting (mobility lease, standard furnished tenancy). Simple, but the income drops — it is a retreat, not a solution.

2. Change the premises' planning designation to hotel-type accommodation (hébergement hôtelier). This is the lasting route for premises that are not dwellings — offices, shops, or premises with a mixed history: a planning authorisation attached to the walls, with no night cap, no quota, no compensation, which regularises the operation once and for all and transfers on resale. It is our core business, paid on success only (€100 excl. VAT per m², minimum €2,500 excl. VAT): the full guide, and the observatory of the thousands of authorisations already granted across France.

3. Sell at yield value. If neither is possible, the best exit is often a sale to a professional buyer able to operate legally — we arrange these sales, discreetly, on a success-fee basis.

With an honest diagnosis. Our city-by-city series of guides sets out the state of the local rules, and our “Can your property be regularised?” checklist runs through the 12 points. For a verdict on your specific property — feasible, under which regime, at what cost — the feasibility study is free and answered within 48 working hours.
