Termination for personal use is regulated differently in Switzerland than many people think. A landlord generally needs no reason for an ordinary termination, not even personal use; conversely, personal use gives the owner no right to get rid of the tenant more quickly, except in one single case after a purchase. The decisive factors are the form, the notice periods and what comes after the termination: a challenge on grounds of abuse and the extension of the tenancy by up to four years. This guide shows when a termination for personal use holds up, how it is served, what an urgent need for personal use after a purchase means, how the conciliation authority assesses extensions and what timeframe a buyer who wants to move into a let flat must expect. At the end you will find what the November 2024 vote changed, namely nothing.
In brief
- In Switzerland an ordinary termination needs no reason; personal use is one of many permissible reasons and must be justified if the tenant asks
- Form: the canton’s official form, by registered post, for married couples and registered partnerships to both persons separately; without the form the termination is void
- Notice periods for flats: at least three months to a customary local termination date; in the Baselbiet the usual dates are the end of March, June and September, but the lease is decisive
- Urgent need for personal use after a purchase: the acquirer may terminate with the statutory notice period to the next termination date, even if the lease runs longer; the need must be current and serious
- The tenant can challenge the termination within 30 days and request an extension: up to four years for flats, up to six for commercial premises; genuine personal use shortens the extension but does not rule it out
When termination for personal use is permitted
Swiss tenancy law recognises freedom of termination: landlords and tenants alike can terminate an open-ended lease without giving a reason, provided they observe the notice period and termination date. The limit is abuse.
Personal use is therefore not a special ground for termination, but a legitimate motive like any other: the owner wants to move in, or a close relative does, for example a child looking for a flat or parents who are to live closer by. The wish to renovate the flat and then use it personally also counts. If the tenant asks for the reasons, the landlord must give them in writing; anyone who refuses or gives a false reason considerably weakens their position if the termination is challenged.
Abusive terminations, which can therefore be challenged, are those that breach the principle of good faith: terminations given in retaliation because the tenant has asserted claims under the lease; during conciliation or court proceedings and for three years afterwards if the tenant won or a settlement was reached; to force the tenant to accept a rent increase; or where the stated personal use is merely a pretext. A pretext means that the landlord has no intention of moving in at all, or that the need is so vague that it cannot be foreseen. Personal use “at some point in the next few years” is not enough; a concrete plan with a date is.
Terminations are barred during ongoing conciliation and court proceedings concerning the tenancy and for three years after they end, unless the landlord urgently needs the property for themselves or close relatives. This is precisely why it pays not to take disputes with the tenant to the conciliation authority if you will need the flat yourself in the foreseeable future.
Notice periods, termination dates and the official form
Mistakes in form and notice periods are the most common reason why terminations for personal use fail. The rules are simple but unforgiving.
Notice period and termination date: for flats, the notice period is at least three months to a customary local termination date or to the date agreed in the lease; longer periods in the lease take precedence. In the Baselbiet the usual termination dates are the end of March, the end of June and the end of September; many leases also allow the end of December or monthly dates except December. The notice must reach the tenant no later than the last day before the notice period begins: for the end of September, that means by 30 June. If it arrives one day too late, it takes effect on the next termination date but is not invalid.
Official form: a termination by the landlord is only valid on the official form approved by the canton. The form states the rented property, the termination date and the procedure for challenging the termination, with the address of the conciliation authority. A letter, even a registered one, is void; the tenant does not even have to challenge it. The form is available from the conciliation office for tenancy matters and from homeowners’ associations.
Delivery: by registered post, to each tenant individually. For married couples and registered partnerships, the termination must reach both persons in separate mailings, even if only one of them signed the lease; the family home enjoys special protection. Receipt is what counts: if the tenant does not collect the item, it is deemed delivered on the seventh day of the collection period.
Reasons: they do not have to appear on the form, but the tenant can request them. If you state the personal use openly and concretely from the outset, with the person, reason and date, you avoid mistrust and are in a better position in conciliation. A termination that is linked to a rent increase or that threatens one is not permitted; see also our guide Calculating a rent increase.
Urgent need for personal use after buying a let flat
Anyone who buys a let flat or house takes over the lease with all its rights and obligations; a sale does not break a lease. For a buyer who wants to move in, the law provides only one concession.
If the new owner claims an urgent need for personal use by themselves, close relatives or in-laws, they may terminate the tenancy with the statutory notice period to the next statutory termination date, even if the lease is for a fixed term or provides for longer notice periods. Urgent does not mean an emergency, but a current, serious and concrete need: the buyer has given notice on their previous home, the family is growing, the commute has become unreasonable. Mere convenience or the intention to re-let the flat at a higher rent is not enough, and the courts examine this closely.
Consequences for the tenant: they can challenge the termination and request an extension, as with any termination. With an urgent need for personal use the extension is shorter, because the buyer’s interest carries great weight; it is rarely ruled out altogether. In addition, the seller is liable to the tenant for the damage if the termination takes place earlier than the lease would have allowed; buyer and seller settle this in the purchase contract, usually with an indemnity clause.
Practical timeline for buyers in the Baselbiet: land register entry in February, termination immediately after the entry with three months’ notice to the end of June; the tenant challenges it and requests an extension; conciliation hearing in the autumn, settlement on a one-off extension until the end of March of the following year. This means that 13 to 14 months pass between purchase and moving in, and two years or more in disputed cases. Anyone who buys a let flat in order to live in it factors this time and the double housing costs into the price. What else matters when buying a let flat is explained in our guide Buying and letting a flat; if you are taking over the flat from an estate, see our guide Selling an inherited house.
Challenging the termination: the 30 days and the procedure
After receiving the termination, the tenant has 30 days to challenge it before the conciliation authority where the flat is located or to request an extension. Both are done with the same application.
The conciliation authority summons both parties to a hearing, in the Baselbiet usually within two to three months. It first examines whether the termination is valid, i.e. whether the form and notice period were observed, and then whether it is abusive. The landlord must substantiate the personal use: who is moving in, why, from when, and what will happen to that person’s current home. Documents help, such as the notice given on that person’s own rented flat, an employment contract in the new location or the birth certificate of the child who needs a flat.
In most cases the hearing ends with a settlement: the termination is accepted and the tenant receives an extension of a few months to two years, often with the right to move out early at short notice. If no settlement is reached, the authority submits a proposed judgment or the matter goes to court. For the landlord, a settlement is almost always the better solution: they get a fixed move-out date instead of proceedings that delay moving in by years.
Avoiding retaliatory termination: if the tenant has won before the conciliation authority or the court in the last three years, or reached a settlement, the termination can in principle be challenged, unless the landlord proves an urgent need for personal use. This also applies if the tenant has obtained a rent reduction based on the reference interest rate. Landlords who will need the property for personal use in the foreseeable future are therefore better off granting justified reduction requests voluntarily, before it comes to proceedings.
Extension: how long the tenant may stay
The extension is the real lever of tenant protection. It postpones the end of the tenancy if the termination would cause the tenant or their family hardship that is not justified by the landlord’s interests.
Duration: for flats a maximum of four years, for commercial premises a maximum of six, in one or two extensions. In personal-use cases, six months to two years are usual. The tenant must request a second extension no later than 60 days before the first one expires.
Weighing of interests: the authority weighs up the circumstances: the duration of the tenancy, the tenant’s personal and financial situation, age, health, children at school, the situation on the housing market, the tenant’s efforts to find a new home and, on the other side, the landlord’s need for personal use. An urgent, documented need for personal use shortens the extension considerably. An 80-year-old tenant after 30 years in the flat gets more time than a young couple after two years.
No extension is granted if the tenant has terminated the lease themselves, has been in payment arrears or has seriously breached their obligations, in the event of the tenant’s bankruptcy, in the case of an urgent need for personal use with a contractual agreement, or if the lease was expressly concluded for a fixed term with a view to an imminent renovation or demolition project.
During the extension, the lease continues unchanged; the landlord may not impose a rent increase, and the tenant can terminate early at short notice, usually one month to the end of a month. At the end of the extension the tenancy ends without any further notice; if the tenant does not move out, the only option left is eviction through the court, which takes a few months in the Baselbiet.
What the vote of 24 November 2024 changed
Two tenancy law proposals were put to the vote in November 2024: tightening the rules on subletting and making termination for personal use easier. Both were rejected by the voters.
The personal-use proposal would have replaced the term “urgent need for personal use” with “significant and current need for personal use”, thereby lowering the hurdle for owners, especially after buying a let flat. Because the proposal was rejected, the previous law still applies: urgency is required, the courts do not interpret it generously, and the extension remains fully available. For buyers and landlords this means that nothing has changed in the timeframes in this guide.
At the same time, Parliament has discussed further changes to tenancy law in the years since 2024, for example on rent-setting models and the official-form requirement. We continuously check which of them come into force and update this guide accordingly; it reflects the situation as at October 2026. For assessing an individual case, especially if a sale with or without the tenant is under discussion, see our guide Sell or let.
How owners should proceed: checklist
Anyone who needs the property for personal use plans backwards from the desired move-in date and allows for an extension. These steps have proven their worth:
- Read the lease: notice period, termination dates, fixed term, special clauses. When buying, do this before signing the purchase contract.
- Document the personal use: who is moving in, why, from when; collect evidence before giving notice.
- Seek dialogue: many tenants move out voluntarily and earlier if they are informed in good time and receive help finding a new home or a contribution towards removal costs. A written termination agreement with a move-out date replaces the notice and is safer for both sides.
- Terminate correctly: official form, by registered post, to each person individually, in good time before the notice period begins, with the reasons stated openly.
- Prepare for conciliation: documents on the personal use, a proposal for a fair extension, willingness to settle.
- Budget time and money: realistically, 9 to 24 months pass between termination and moving in; during this time the rental income continues, but so do your own housing costs.
We support owners and buyers in the Baselbiet through termination, conciliation and handover, negotiate termination agreements and, on request, carry out the check-out inspection of the flat. If you sell instead, you will find the process in our guide Selling a house: the process in 8 steps.
Questions on this topic.
Can I terminate my tenant’s lease for personal use?
Yes. In Switzerland an ordinary termination needs no reason; personal use is a permissible motive. You need the official form, compliance with the notice period and termination date, and delivery to each tenant individually. The tenant can challenge the termination and request an extension.
What notice period applies to a termination for personal use?
For flats at least three months to a customary local or contractual termination date, in the Baselbiet usually the end of March, June and September. Longer periods in the lease take precedence. Only in the case of an urgent need for personal use after a purchase may the acquirer terminate with the statutory notice period to the next statutory termination date.
What is an urgent need for personal use after a purchase?
A current, serious and concrete need on the part of the buyer or close relatives to live in the flat themselves, for example because the lease on their own home has been terminated or the family is growing. It allows termination with the statutory notice period even for longer leases; an extension remains possible but is shorter.
How long an extension can the tenant obtain?
Up to four years for flats, up to six for commercial premises. Where a need for personal use has been proven, six months to two years is usual. The authority weighs up the duration of the tenancy, the tenant’s personal situation, the housing market and the urgency of the need for personal use against each other.
Is a termination by letter valid?
No. A termination by the landlord is only valid on the official form approved by the canton, delivered by registered post. For married couples and registered partnerships, each of the two persons must receive their own copy. A letter is void, even if the tenant does not react.
Did the November 2024 vote make termination for personal use easier?
No. The proposal to replace the urgent need for personal use with a significant and current need for personal use was rejected on 24 November 2024. The previous law continues to apply, with the urgency requirement and the full possibility of an extension.
Move into the flat yourself or sell it?
We review your lease, prepare the termination in the correct form, negotiate termination agreements with the tenant and support you through to the handover.
