French Rental Notice Period for Expats: 1 or 3 Months? The 2026 Rules

Everything starts with what kind of lease you signed:

Unlike the landlord, you can leave at any time during the lease — no need to wait for the term, and you never have to justify leaving as such. The only question is how long the préavis runs.

If your lease is furnished, you can stop reading the next two sections: your notice is one month, full stop, whatever the commune and whatever your reason. For unfurnished leases, the default is three months — but a surprising number of tenants qualify for one month without knowing it, and a smaller (but real) number think they qualify when they don't. That second group is the expensive one.

The best-known route to a one-month notice on an unfurnished lease is the zone tendue: if the dwelling sits in a designated high-pressure housing area, art. 15, I, 1° cuts your préavis to one month automatically — no personal justification needed.

Here is the part that even many French-language sites get wrong. You'll often read that "the zone tendue covers some 3,700 communes." That larger figure mixes two different lists:

• List 1 — the one that matters for your préavis: the annex of décret n° 2013-392, covering zones d'urbanisation continue de plus de 50 000 habitants (art. 232 I 1° of the tax code) — 1,434 communes after the updates by décret n° 2023-822 and décret n° 2025-1267. Paris and its agglomeration, Lyon, Marseille, Lille, Bordeaux, Toulouse, Nice, Nantes, and the other large urban units.
• List 2 — tax only: roughly 2,263 additional "tourist-tension" communes (art. 232 I 2°), added in 2023-2024 so that resort towns and coastal communes could apply the surtax on second homes and the vacant-dwelling tax. Being on this second list does not reduce a tenant's notice period — a reading confirmed by both ANIL and UNPI, and matched by the official service-public simulator.

So a tenant in a Breton seaside commune or an Alpine ski village may correctly read that their commune is "en zone tendue" for tax purposes — and still owe three months of préavis. Quoting the wrong list in your notice letter doesn't just fail; it can leave you liable for the full three months of rent.

Before writing anything, check your exact commune and compute your exact leaving date with AdminLanding's free notice-period simulator — it applies the décret's first list, not the headline figure.

Zone tendue is only ground 1° of art. 15, I. Even outside the 1,434 communes, your unfurnished-lease notice drops to one month if you fit one of these situations:

• 2° — Work events: obtaining a first job, a professional transfer (mutation), loss of a job, or a new job following a job loss. This is the expat's workhorse ground — a relocation ordered by your employer, a redundancy, or landing a job after a period of unemployment all qualify. Note the sequencing: a new job after losing one counts; resigning to take a better job generally does not.
• 3° — Health: a state of health, confirmed by a medical certificate, that justifies a change of dwelling.
• 3° bis — Domestic violence: a tenant protected by an ordonnance de protection, or whose partner is being prosecuted or has been convicted for violence against them or a child of the household (added by loi n° 2020-936).
• 4° — Benefits: tenants receiving RSA or AAH.
• 5° — Social housing: being allocated a logement social.

One precision worth flagging because it circulates wrongly: these grounds live in art. 15, I — paragraph III of the same article is the elderly-tenant protection against a landlord's congé, and has nothing to do with your reduced préavis. If a template letter you found cites "article 15 III" for a job transfer, bin the template.

The préavis does not run from the day you post your letter. Under art. 15, I, it runs from the day the landlord receives it, and only three delivery methods are valid:

• Registered letter with acknowledgement of receipt (LRAR) — the period starts on the day the landlord signs for it;
• Hand delivery against a signed récépissé or émargement;
• Service by a commissaire de justice (the officer formerly called huissier).

An email, a WhatsApp message, or an ordinary letter starts nothing, even if the landlord clearly read it.

Now the trap. If you send an LRAR and the landlord never collects it at the post office, the Cour de cassation is blunt: a registered letter that is not actually delivered does not trigger the notice period at all (Cass. 3e civ., 24 Sept 2020, n° 19-16.838). Your préavis silently never started, and rent keeps accruing. The court applied the same logic to the electronic registered letter (LRE) in 2025 (Cass. 3e civ., 7 May 2025, n° 23-13.151).

Practical consequences for an expat on a moving deadline:

1. Send the LRAR early, and track it — 'avisé' (notice left) is not 'distribué' (delivered).
2. If the tracking shows the letter sitting unclaimed, don't wait out the storage period hoping: fall back on a commissaire de justice, whose service is valid even against a landlord dodging the postman.
3. If the landlord is local and cooperative, hand delivery against a signed and dated receipt is free and instant.

French notice periods count de quantième à quantième — day-for-day, calendar-style, with no adjustment for weekends or public holidays. The rules, as set out in service-public.fr file F32360:

• The period ends on the same day-number in the target month as the day the landlord received the notice.
• If the target month has no such day, the period ends on that month's last day.
• Saturdays, Sundays and holidays count like any other day, including as the final day.

Worked examples for a one-month préavis:

• Landlord signs the LRAR on 5 September → the lease ends 5 October.
• Landlord signs on 30 January → February has no 30th → the lease ends 28 February (29 in a leap year).

And for the three-month default: notice received 14 July → lease ends 14 October. You owe rent (and remain responsible for the dwelling) through that final day; the état des lieux de sortie and key handover typically happen on or before it. If the maths plus the commune check feel error-prone — they are; that combination is exactly what the free préavis calculator on AdminLanding resolves in one pass, in English.

The reduced préavis is not automatic paperwork-wise: art. 15, I requires the tenant to state the ground and justify it at the moment of the congé. Two Cour de cassation rulings define exactly what that means:

• Personal grounds (job, health, RSA/AAH, social housing): the justificatif — transfer letter, termination document, medical certificate, benefit attestation — must accompany the notice letter. A tenant who invoked a professional transfer but only produced the proof during litigation was held to the full three months: supplied afterwards, the document doesn't count (Cass. 3e civ., 11 Apr 2019, n° 18-14.256).
• Zone tendue: you must state the ground, but no attachment is legally required — mentioning that the dwelling is in a zone tendue, together with the address of the dwelling itself, is enough, and the landlord can't demand more (Cass. 3e civ., 11 Jan 2024, n° 22-19.891). Citing décret n° 2013-392 in the letter is good practice all the same.

And the mirror-image mistake: if you send a bare notice letter with no ground stated and nothing attached, the three-month period applies — you cannot repair it retroactively by sending the justificatif two weeks later. The safe template is therefore: identify the lease and the dwelling, give notice, state the precise legal ground (quote the article and sub-paragraph), attach the proof if the ground is personal, and ask for the état des lieux de sortie date in the same letter.

While you're preparing the exit, remember the other end of the money: the deposit. Our sister guide on getting your security deposit back covers the one/two-month restitution deadlines and the penalty interest landlords owe when they sit on it.

Serving notice doesn't stop the rent. Under the rules summarised at service-public.fr F1168, you owe rent and charges for the entire préavis, even if you move out and return the keys earlier. There are only two exits: the landlord agrees in writing to end it sooner, or a new tenant moves in before your period expires — from that day, you owe nothing more. If you leave early without either, the landlord can claim the balance.

For completeness, the landlord's notice (congé du bailleur) is a different regime altogether: 6 months before the lease term for an unfurnished dwelling, 3 months for a furnished one, and only for sale, repossession (reprise), or a legitimate and serious ground (service-public.fr F929). If it's your landlord ending the lease rather than you, that's the framework to read — not this one.
