Swiss Tenancy Law 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 hosts are asking 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 pursue your homestay housing projects with complete peace of mind.

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

To fully understand the 2026 legal landscape, we need to take a step back. In 2024, a draft revision of the Code of Obligations (CO) made many headlines. This text aimed to restrict subletting drastically, notably by imposing a strict maximum duration of two years and the requirement to obtain mandatory written consent from the landlord. These measures would have significantly complicated life for 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 modification of tenancy law with 51.58% against. This result, warmly welcomed by ASLOCA (Swiss Tenants' Association), put a sharp halt to attempts to limit tenants' rights. The flexibility of the Swiss real estate market, essential in a context of housing shortages, has thus been preserved.

Today, in 2026, none of these new restrictions are in effect. Long-term subletting remains fully legal and accessible, without any arbitrary duration limits. 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 illegally due to the length 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 a crackdown does not mean an absence of rules. It is crucial to respect the existing legal framework to ensure your subletting experience is a total 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 law 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

The number one rule, which has not changed a bit, is the obligation to obtain prior consent from your landlord (or your property management agency, often called a "régie" in French-speaking Switzerland) before subletting all or part of your accommodation. This consent is the cornerstone of a legal and peaceful subletting arrangement. 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 planned), we recommend that you request written proof. A simple confirmation email or a signed letter from your agency 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 case law is strict: unauthorized subletting, especially if accompanied by profit, justifies the 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. Since his children have 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 agency, detailing the conditions of the subletting. The agency grants its consent in writing within 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 for getting rich, but a solution for sharing costs. The rent you charge 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 based on the surface area or the number of rooms sublet. If you rent the room furnished (which is the norm on Roomlala), Swiss law allows for 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 subletting, but they can also demand the return of the profits made. Furthermore, the subtenant has the right to contest this rent before the conciliation authority (for example, with the support of ASLOCA) if they feel they have been harmed.

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 compliant 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 respect 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 very specific situations. At Roomlala, we help you anticipate these eventualities to ensure the success of your project.

The first ground for refusal is the tenant's refusal to communicate the conditions of the subletting. 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 finds that you are trying to make money unreasonably through subletting, they will block the procedure. They have the right to verify your calculations to ensure the fairness of the transaction.

The third ground concerns major inconveniences for the landlord. This includes very specific situations, for example if the subletting leads to clear overcrowding of the apartment (too many people for the size of the housing), 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 subletting by citing major inconveniences (noise pollution for the neighbors). This refusal is legal. However, if Thomas had chosen a subtenant with a traditional profile via Roomlala, the landlord would have had no valid grounds to oppose it.

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

Now that you are reassured about the preservation 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 to ensure your experience on Roomlala is smooth, secure, and 100% legal.

Prepare a solid file for your management agency

Proactivity is your best ally. Do not wait for your agency to discover by chance that someone else is living in your home. 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 contain the following elements:

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

By providing all this information up front, you head off any requests for additional information that could slow down the process. Remember that the agency 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 duration of 6 months. He immediately sends an email to his agency with the draft sublease agreement generated thanks to the platform's information. Faced with such a complete and transparent file, the agency gives him its agreement by return mail in less than a week.

Draft a clear sublease agreement and manage the deposit

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

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

The amount of this security deposit cannot exceed three months of net rent. At the end of the subletting, 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 deposit equivalent to one month's rent. She accompanies her subtenant to the bank to open a security 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: Serenity 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, 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 demonstrating transparency, you have all the cards in hand to have an exceptional shared housing experience. Don't wait any longer, publish your listing or look for your future room today, in complete legality and with complete peace of mind!
