Most of what determines how cleanly a Luxembourg tenancy ends is decided three months before anyone cleans anything. The notice has to be served correctly, on the right kind of contract, and the exit sequence has to be scheduled rather than improvised.
Which contract you are actually on
Everything depends on whether your lease is fixed-term or open-ended, and many tenants are on a different one from the one they signed. A fixed-term lease that is not terminated before its end date does not simply lapse: since the 2024 reform it converts automatically into an open-ended contract, and the anniversary date of the original lease stops governing your exit.
That conversion is good news. On an open-ended contract the tenant may terminate at any time with three months' notice, without waiting for an anniversary. On a fixed-term contract still within its initial period, you are held to the term, and terminating early can leave you liable for rent to the end of the term if the property is not re-let, plus damages if the landlord suffers further loss.
Check the signature date and the initial duration in your contract before you do anything else. If you are past the initial period, the three-month notice applies and you have flexibility. If you are inside it, the conversation with the landlord is a negotiation rather than a right.
Serving notice so that it counts
Where the lease specifies a method, follow it. Where it does not, notice can technically be given by other means, but the strong recommendation is a registered letter with acknowledgement of receipt. The reason is evidential: the three-month clock and the date your obligations end both depend on when the landlord received the letter, and an email that the landlord later says went to spam is a weak position from which to argue about two months' rent.
Keep the letter short and factual. State the property, the contract date, the fact that you are terminating, and the date on which the notice period expires. Two additions strengthen it materially: confirm that you will pay rent and charges through to your effective departure, and propose two or three concrete dates for the exit inventory. Proposing dates puts the scheduling initiative with you, which matters, because the return of your guarantee is keyed to the exit inventory rather than to your notice letter.
What the landlord can and cannot do
The asymmetry runs in the tenant's favour. A landlord cannot terminate an open-ended residential lease without cause. Termination has to rest on one of a limited set of legitimate grounds, has to be reasoned in writing, and is void if it is not.
- Personal need — the landlord wants the property for themselves or a relative within the permitted degree of kinship. Notice is six months, and the formalities here are stricter than for other grounds.
- Serious breach by the tenant — unpaid rent, significant damage, or another substantial failure of contractual obligations. The burden of establishing the breach falls on the landlord.
- Demolition or reconstruction that makes occupation impossible.
One case newcomers meet often: the apartment is sold during the tenancy. A sale does not by itself end your lease. If the buyer wants to occupy the property personally, or house a relative within the permitted degree, they must send you a registered termination letter within three months of the acquisition, with six months' notice. If they miss that window, the lease continues on its existing terms with the new owner as landlord.
The ninety-day sequence
Day 90 — notice served. Registered letter sent, proposed exit inventory dates included. Diary the expiry date.
Day 75 — documents pulled. Retrieve the entry inventory and its photographs, and read them against the flat as it stands today. Everything you find now is something you can fix at your own pace and your own price.
Day 60 — repairs booked. Filling and touching in wall marks, re-siliconing a shower joint, replacing a cracked toilet seat or a blown oven lamp, descaling taps. Each of these appears as a contractor line item if a landlord organises it.
Day 30 — utilities and administration. Contact your electricity and gas supplier to arrange the closing meter reading; a week is the minimum they ask for and the end of the month is their busiest period. Notify the commune of your change of address. Redirect post. Confirm the exit inventory date in writing.
Day 7 — deep clean. Not before, or it will need doing twice. Oven, extractor filters, window frames and tracks, radiator backs, inside of cupboards, and the cave, which is the space most often forgotten and most visibly empty on inspection day.
The exit inventory itself
Attend it. Do not delegate it to a friend or leave the keys with the agent. The exit document is the comparator against your entry document, and the moment to contest a description is while it is being written, not afterwards.
Hand over every key, badge and remote control listed on the entry inventory, counted in front of the other party, and have the number recorded on the document. Missing access devices are one of the few deductions a landlord can justify with a real invoice, because reprogramming a building's access system is genuinely expensive.
Where you and the landlord cannot agree on the condition of something, say so and have the disagreement written into the document rather than signing a version you dispute. Either party may bring in a commissaire de justice, at shared cost, to produce a neutral record.
When the money comes back
Where the exit inventory matches the entry inventory and all rent has been paid, half the guarantee is due within one month of the handover of keys. The second half follows within one month of the annual charges being approved by the general assembly of co-owners, or of the charges statements arriving, which can be many months later.
Where damage is recorded, the landlord may retain the disputed portion, but the undisputed portion still has to be returned on time. Any deduction has to rest on objectively verifiable evidence; a figure typed by the landlord into a spreadsheet, with no invoice or third-party assessment behind it, generally carries no probative value. If a deadline passes without payment or explanation, the route is the commune's rent commission, which is free to petition.
Three questions we are asked
Can I leave earlier than the end of my notice? You can vacate whenever you like, but you remain liable for rent and charges until the notice expires unless the landlord agrees otherwise or re-lets in the meantime. Where a replacement tenant is available, most landlords will negotiate.
My flatmate is leaving and I am staying. What changes? On a single joint lease, the departing flatmate must notify the landlord and the other tenants simultaneously with three months' notice, and must find a replacement or demonstrate a genuine search. An intermediate inventory documents the condition on the day they go, and the guarantee is not paid out individually: it stays lodged until the lease ends for everyone.
Should I repaint before leaving? Only if the lease requires it or the entry inventory recorded fresh paint. Repainting an entire flat that was already worn when you arrived is money spent to fix someone else's wear.
Editorial note: Luxembourg residential tenancy law changed on 1 August 2024 through the law of 23 July 2024, which amended the law of 21 September 2006. Leases signed before that date remain governed by the rules in force when they were signed, and market conventions are not legal rules. Confirm the current position with logement.public.lu, guichet.lu, the commune’s rent commission or a lawyer before relying on any of the above.
