Lease Law in Switzerland 2026: Your rights upheld for long-term subletting

You may have recently heard alarming rumors regarding a tightening of subletting rules in Switzerland. Many tenants and landlords are asking themselves legitimate questions: is it still possible to sublet a room for a long period in 2026? Must we face complex new legal restrictions? At Roomlala, we are committed to supporting you with reliable and reassuring information. The good news is that the alleged legal revolution did not happen. We will decipher the current situation together to allow you to continue your homestay accommodation projects with complete peace of mind.

The rejection of the 2024 revision: A victory for subletting in Switzerland

To fully understand the legal landscape of 2026, we must take a short step back. In 2024, a draft revision of the Code of Obligations (CO) made many headlines. This text aimed to drastically restrict subletting, notably by imposing a strict maximum duration of two years and the obligation to obtain mandatory written agreement from the landlord. These measures would have considerably complicated the lives of students, expatriates, and tenants wishing to share their homes in the long term.

However, the Swiss people decided decisively. During the federal vote on November 24, 2024, citizens definitively rejected this change to tenancy law with 51.58% against. This result, widely welcomed by the ASLOCA (Swiss Tenants' Association), marked a clear halt to attempts to limit tenants' rights. The flexibility of the Swiss real estate market, which is essential in a context of housing shortages, has thus been preserved.

Today, in 2026, none of these new restrictions are therefore in effect. Long-term subletting remains fully legal and accessible, without any arbitrary time limit. For the Roomlala community, this means that you can continue to offer a spare room or look for a homestay for several years if you wish, without fearing that you are acting unlawfully because of the duration of your agreement.

We want to reassure you: this legal stability is excellent news. It maintains a healthy balance between the rights of tenants to optimize their living space and the rights of landlords to keep an eye on their property. However, the absence of tightening does not mean the absence of rules. It is crucial to respect the existing legal framework so that your subletting experience is a complete success.

Article 262 of the Code of Obligations: The golden rules still in force in 2026

Since the revision was rejected, it is the historic and solid Article 262 of the Swiss Code of Obligations that continues to govern subletting in 2026. This piece of legislation is clear, balanced, and aims to protect all stakeholders. At Roomlala, we strongly encourage you to master its subtleties to avoid any disputes. Here are the two fundamental pillars of this article that you must strictly respect.

The landlord's consent: A mandatory step

Rule number one, which has not changed one iota, is the obligation to obtain prior consent from your landlord (or your property management, often called "régie" in French-speaking Switzerland) before subletting all or part of your home. This consent is the cornerstone of a legal and worry-free sublease. Ignoring this step exposes you to the risk of having your own lease terminated prematurely.

Although the 2026 law does not formally require this agreement to be in writing (contrary to what the aborted revision intended), we recommend that you require written proof. A simple confirmation email or a signed letter from your property management will protect you in the event of a change of owner or a future dispute. Transparency is always the best strategy.

If you fail to request this authorization, the consequences can be serious. Swiss jurisprudence is strict: an unauthorized sublease, especially if accompanied by a profit, justifies termination of the main lease. It is therefore imperative to begin the process as soon as you find the ideal subtenant on our platform.

Concrete example: Take the case of Marc, a tenant of a large apartment in Geneva. With his children having left the family nest, he decides to sublet two rooms on Roomlala to international students. Even before confirming the bookings, Marc sends a complete file to his property management, detailing the terms of the sublease. The management grants him its written consent in a few days, allowing Marc to generate extra income legally and without any stress.

The strict prohibition of abusive profit

The second pillar of Article 262 CO is the formal prohibition of making an excessive profit at the expense of your subtenant. Subletting is not a business model to get rich, but a solution for sharing costs. The rent you ask of your subtenant must be proportional to what you pay yourself to the main landlord.

How do you calculate a legal subrent? You must divide your main rent according to the surface area or the number of rooms sublet. If you rent the room furnished (which is the norm on Roomlala), Swiss law tolerates a surcharge for the depreciation of furniture, the use of Wi-Fi, and utilities (water, electricity). This surcharge is generally between 10% and 20% of the proportional rent, depending on the quality of the furnishings.

If you set an abusive rent, not only can the landlord refuse the sublease, but they can also demand the return of the profits made. In addition, the subtenant has the right to contest this rent with the conciliation authority (for example, with the support of the ASLOCA) if they feel aggrieved.

Concrete example: Sophie rents a 4-room apartment in Lausanne for 2000 CHF per month, including utilities. She decides to sublet a furnished room that represents about a quarter of the total surface area. The base rent for the room would be 500 CHF. By adding a 15% surcharge for recent furniture, internet access, and electricity, Sophie offers her room on Roomlala at 575 CHF per month. This calculation is fair, transparent, and perfectly in line with the 2026 Swiss law.

The landlord's legal grounds for refusal: What you need to know

It is important to emphasize that if you follow the rules, your landlord cannot arbitrarily oppose your subletting project. Swiss law protects the tenant by strictly limiting the landlord's grounds for refusal to three specific situations. At Roomlala, we help you anticipate these possibilities to ensure the success of your approach.

The first ground for refusal is the tenant's refusal to disclose the conditions of the sublease. If you hide the identity of your subtenant, the planned duration, or, above all, the amount of the subrent, the landlord has the right to say no. This is why preparing a transparent file is absolutely vital.

The second ground, as we saw previously, is abusive profit. If the landlord sees that you are trying to make money in an unreasonable way through subletting, they will block the process. They have the right to check your calculations to ensure the fairness of the transaction.

The third ground concerns major disadvantages for the landlord. This includes very specific situations, for example, if the sublease leads to clear overcrowding of the apartment (too many people for the size of the unit), or if the subtenant plans to engage in a noisy or commercial activity in a strictly residential building.

Concrete example: Thomas, a tenant in Fribourg, wants to sublet a room to a music student who needs to practice for several hours a day on an acoustic drum kit. The landlord refuses the sublease, citing major inconveniences (noise pollution for the neighbors). This refusal is legal. However, if Thomas had chosen a subtenant with a standard profile via Roomlala, the landlord would have had no valid grounds to oppose it.

How to succeed with long-term subletting with Roomlala in Switzerland?

Now that you are reassured about the maintenance of your rights in 2026, it is time to take action. Hosting someone or finding a homestay is a wonderful human adventure, provided you are well organized. We have compiled the best practices for you so that your experience on Roomlala is smooth, secure, and 100% legal.

Prepare a solid file for your property management

Proactivity is your best ally. Do not wait for your property management to accidentally discover that someone else is living at your place. As soon as you have found an agreement in principle with a member of the Roomlala community, put together a file requesting authorization to sublet. This professionalism will instantly reassure your landlord.

Your file must necessarily contain the following elements:

• The full contact details of your future subtenant (surname, first name, date of birth).
• A copy of their identity document and, if they are a foreigner, their residence permit (permit B, C, or L).
• The planned duration of the sublease (start and end dates, or mention of an indefinite duration).
• The exact amount of the subrent and the details of the utilities included.

By providing all this information from the start, you cut short any requests for additional information that could slow down the process. Remember that the property management has a reasonable response time (usually two to four weeks), so you must plan ahead.

Concrete example: Julien, a tenant in the canton of Vaud, found an intern via Roomlala for a period of 6 months. He immediately sends an email to his property management with the draft sublease contract generated using information from the platform. Faced with such a complete and transparent file, the management gives him its agreement by return mail in less than a week.

Draft a clear sublease contract and manage the security deposit

Once the landlord's agreement is in hand, it is essential to formalize your relationship with your subtenant with a written contract. Although an oral contract is valid in Switzerland, it is a source of endless conflicts in the event of a problem. The sublease contract must reflect the main conditions of your own lease (quiet hours, use of common areas, laundry room rules, etc.).

A crucial point in Switzerland concerns the rent security deposit. Swiss law is very strict on this subject: you cannot simply collect the security deposit money into your personal bank account. The money must be deposited in a blocked bank account in the name of the subtenant (rent deposit account), or guaranteed by a surety company (such as SwissCaution or Firstcaution).

The amount of this security deposit cannot exceed three months of net rent. At the end of the sublease, if no damage is found during the move-out inventory check (another essential step!), you will have to sign a form to release this money to the subtenant.

Concrete example: Elena, who sublets a room in Neuchâtel, asks for a security deposit equivalent to one month's rent. She accompanies her subtenant to the bank to open a rent deposit account in their name. Thus, Elena is protected in case of damage, and the subtenant is reassured to know that their money is safe in a blocked account, in accordance with Swiss law.

Conclusion: Peace of mind at the heart of your housing project

In summary, the 2026 revision only confirmed the attachment of the Swiss to a certain freedom in the housing sector. Long-term subletting still has a bright future ahead of it, and tenants' rights are firmly maintained thanks to the rejection of the 2024 vote. At Roomlala, we are proud to offer you a secure platform to facilitate these connections. By respecting the obligation of consent, applying fair rent, and showing transparency, you have all the cards in hand to have an exceptional shared housing experience. Do not hesitate any longer, publish your listing or look for your future room today, in full legality and with complete peace of mind!
