Paris Is 90 Nights Now, Not 120
If you learned the French rules a couple of years ago, you learned 120 nights. For Paris that number is now wrong, and it has been wrong since January 2025.
We know because we shipped it wrong ourselves. Our Paris preset said 120 for a day, and checking it against the authority before writing this article is how we found out. A host relying on it would have been thirty nights over with everything reading green — which is a good illustration of why a number you have not re-checked is not a number you can rely on.
Checked 27 September 2026. Short-term letting rules move fast — Paris cut its cap in January 2025 and Amsterdam cut parts of the city in April 2026. Verify against the authority before you act on anything here. This is general information, not legal advice.
What changed
The loi Le Meur — Law 2024-1039 of 19 November 2024 — gave communes the power to lower the principal-residence cap from 120 nights to 90 by reasoned deliberation.
Paris used it immediately. Deliberation 2024 DLH 398, adopted in December 2024, set the ceiling at ninety days in the same calendar year, effective 1 January 2025.
So there are now two French numbers, and which applies depends on your commune:
- Paris: 90 nights per calendar year.
- France generally: 120 nights, unless the commune has cut it — many have, and the national framework describes the range as 90 to 120 depending on the municipality.
If you let outside Paris, look up your own commune. Do not assume 120 because that is what the internet said in 2023.
The conditions attached
It must genuinely be your principal residence — you live there at least eight months of the year. The cap exists to let residents monetise a home they actually live in. A second home or an investment flat is a different regime entirely, with change-of-use and compensation rules that are considerably heavier.
You need a registration number. Paris issues a 13-character municipal number that must appear on every listing. It is free and one-off, through the national téléservice. Since 20 May 2026 the declaration-with-registration requirement extends to every commune and every meublé de tourisme — the same date the EU’s reporting regime starts, which is not a coincidence.
There is a separate rule about single guests. You may not let your principal residence to the same customer for more than 90 consecutive days. That is a limit on one booking’s length, not on your annual total — a different axis entirely, and easy to miss because the number happens to match.
Going over is expensive. Exceeding the cap as a principal-residence owner carries a civil fine of up to €15,000.
Counting it
Paris counts nights let, not nights offered — so leaving the calendar open costs you nothing, and the risk is concentrated in a good year rather than a quiet one.
The settings are:
- What you count: nights let (occupancy)
- Per night
- Calendar year, resetting 1 January
- Limit 90
Choose “Paris (90 nights)” and that is done. If you are elsewhere in France and your commune has not cut the cap, choose “France — principal residence (120 nights)” instead, then check your mairie.
Why 90 is harder to manage than 120 sounds
Losing thirty nights is not a 25% cut in a smooth year. It is a 25% cut that lands entirely on your best weeks, because those are the weeks that sell.
A Paris flat that used to fill 120 nights across summer, the autumn trade-show season and Christmas now has to fit the same demand into 90. Something gets dropped, and if you let the calendar decide, what gets dropped is whatever happens to be asked for last — not whatever is worth least.
That is the decision worth making deliberately. Rank the year by what a night actually earns, then give up from the bottom: the flat February midweeks go, the June weekends stay. Airflow will do that ranking against your own rates and close the cheapest nights in a rolling way, keeping a protected horizon so it never touches bookings you are about to take.
It is the same arithmetic as choosing which nights to block for any other reason. The cap just makes it compulsory.
What to do this week
Knowing the number is not the same as being able to prove it, and the proof is the part that takes months to accumulate. It is worth starting before you need it.
- Create an account — start free; a card is needed at sign-up.
- Import your booking history. Paste your Airbnb or Booking.com iCal link, or upload a CSV. Past bookings come in too, so the counter is right from the first day rather than from today.
- Turn on the letting limit for the property and pick your city’s rule from the list. It is four settings — what you count, per night or per room-night, over which window, up to what limit — and the presets fill them in.
- Add your registration number once. It renders on your listing wherever Airflow publishes it.
Then leave it alone. It counts every night, tells you the date you are forecast to cross, and can close the least valuable nights automatically to keep you under.
