The legal framework for subletting in Switzerland 2026: What has (really) changed

The rejection of the two-year limit (November 2024 vote)

To fully understand the situation in 2026, we need to take a step back. At the end of 2024, a proposed revision of the Code of Obligations shook the rental world. This project aimed to restrict subletting drastically, notably by imposing an arbitrary duration limit of two years. At Roomlala, we followed these debates very closely, as they directly threatened the sharing economy and housing flexibility.

Fortunately for tenants, the Swiss people decided. During the federal vote on November 24, 2024, this restrictive amendment was rejected with 51.58% against. Tenant advocacy associations, notably ASLOCA, played a crucial role in informing the public about the dangers of this law. This historic vote helped maintain a fair balance between the rights of landlords and tenants.

Today, in 2026, long-term subletting remains fully legal. There is no duration limit imposed by federal law. If you are going abroad for work for three years or wish to host a student for the entire duration of their bachelor's degree, you are perfectly entitled to do so, provided you intend to return to the home or that the partial subletting (one room) falls within the duration of your own lease.

Article 262 of the Code of Obligations: Still your best ally

Since the revision was rejected, the illustrious Article 262 of the Code of Obligations (CO) remains the absolute standard regarding subletting tenancy law. This article clearly stipulates that the tenant has the right to sublet all or part of their home. It is a fundamental right that cannot be taken away by a simple clause in your lease agreement.

However, this right is not unconditional. Article 262 specifies that subletting is subject to the landlord's consent (the owner or the property management company). This point is crucial: you cannot sublet in secret. At Roomlala, we always encourage complete transparency. A relationship of trust with your landlord is the key to a successful and serene subletting experience.

It is important to note that many standard lease agreements still contain a clause prohibiting subletting in principle. Legally, in Switzerland, such a general prohibition clause is considered void. Your landlord cannot absolutely forbid you from subletting. They must examine each request on a case-by-case basis, according to very strict criteria defined by law.

How to rent your room legally and obtain the landlord's consent?

The golden rule: prior written consent

To rent your room legally, the first essential step is to obtain your landlord's agreement before your subtenant even arrives. Subletting without asking for this authorization exposes you to major risks. Indeed, a landlord discovering an undeclared sublet is entitled to demand the immediate termination of your own lease for breach of trust, leaving you without a home.

At Roomlala, we strongly advise you to always make your request in writing, ideally by registered mail. Your request must be transparent and contain all the information necessary for the landlord to make their decision. Here is what you must provide them:

• The full identity of the subtenant (last name, first name, copy of an ID).
• Financial conditions (the amount of the sublet rent and utility charges).
• The planned duration of the sublet (start and end dates, or mention of an indefinite period).
• The intended use of the premises (exclusively for residential purposes).

Once the request is sent, wait for the written response from your management company or landlord. Never settle for a simple oral agreement over the phone, because in the event of a dispute, you would have no proof to provide. Written consent is your best insurance to sleep soundly.

The three legitimate grounds for refusal by the landlord

As mentioned previously, your landlord cannot refuse your subletting request out of simple caprice. Swiss housing law is very clear on this: refusal is only valid for three strict and exhaustive reasons. If your situation does not fall into one of these three categories, the landlord is obliged to accept.

The first ground for refusal is the tenant's refusal to communicate the conditions of the sublet. If you hide the name of your subtenant or the amount of rent you will charge, the landlord is entitled to say no. Transparency is therefore your best ally.

The second ground concerns abusive conditions. The landlord will ensure that you are not making a profit on their back (we will come back to this in detail in the next section). If you rent your apartment for 1500 CHF and you sublet a room for 1200 CHF, the landlord will categorically refuse due to abusive overpricing.

The third ground is a major disadvantage for the landlord. This criterion is assessed on a case-by-case basis. For example, if you sublet a 20m2 studio to a family of four, the landlord will invoke overcrowding. Similarly, if the subtenant has notoriously problematic behavior or uses a residential room to set up a noisy workshop, the refusal will be justified.

Avoiding financial pitfalls: The "zero-profit" rule

How to calculate a fair rent for your subtenant?

One of the pillars of subletting in Switzerland 2026 is the strict prohibition of making a financial profit. The legislator considers that the primary tenant should not get rich thanks to a property they do not own. The rent you ask your subtenant for must therefore cover only actual expenses, without any profit margin.

To calculate a fair rent, you must base it on the main rent you pay, including utilities, and divide it proportionally. The most common and accepted method by management agencies is the square-meter calculation. You must take into account the surface area of the room rented exclusively, as well as a share of the common areas (kitchen, bathroom, living room).

Let's take a concrete example: you rent a 100m2 apartment for a total rent of 2000 CHF per month. You decide to sublet a 20m2 room, and the subtenant has access to 40m2 of common areas that they share with you (i.e., 20m2 equivalent for them). The total surface area attributed to them is therefore 40m2. The fair rent would be (2000 / 100) x 40 = 800 CHF per month. You can add half of the electricity and internet bills to this.

The furnished exception: the depreciation surcharge

There is a legal exception to the strict proportional rent rule. If you offer a furnished room on Roomlala, you are entitled to apply a slight surcharge to the base rent. This surcharge is not considered profit, but financial compensation for the wear and tear of your own furniture (bed, wardrobe, desk, television, etc.).

In Switzerland, jurisprudence and associations such as ASLOCA agree that a surcharge for furniture depreciation is acceptable if it is between 15% and 20% maximum of the base rent of the room. Going beyond this percentage could risk putting your contract into the category of abusive conditions, justifying a refusal by the landlord.

For example, if the proportional rent for the empty room is calculated at 500 CHF, you can legally ask your subtenant for a furnished rent between 575 CHF and 600 CHF. At Roomlala, we recommend that you keep the purchase invoices for your furniture. In case of an audit by the management company, you will be able to easily justify this surcharge and prove your good faith.

Responsibilities and best practices for serene cohabitation

The primary tenant remains the sole guarantor

It is fundamental to understand that subletting does not create any direct legal link between your subtenant and your landlord. As the primary tenant, you remain the sole legal and financial entity responsible to the landlord. This is called joint and several liability.

Concretely, this means that if your subtenant does not pay you their rent at the end of the month, you are still required to pay the full main rent to your management company. The owner will not go after the subtenant; they will go after you. Similarly, if the subtenant causes damage to the apartment (stain on the floor, broken window), it is your security deposit that will be used at the end of the lease.

To protect yourself, we advise you to require your subtenant to provide a private civil liability (RC) insurance policy valid in Switzerland, as well as a security deposit equivalent to one or two months of rent. Always draft a written and detailed subletting contract, and carry out a thorough inventory check upon entry and exit. On Roomlala, our platform facilitates these steps to provide you with a secure framework.

Focus on the canton of Vaud: The new RULV of July 2026

While federal law sets the general guidelines, it is important to stay attentive to cantonal specificities. For example, in the canton of Vaud, new Vaudois rental rules and customs (RULV) came into effect on July 1, 2026. These new directives further clarify and regulate the practice of subletting at the local level.

The 2026 RULV strongly emphasize the obligation to formalize communications. They reiterate that the landlord's written consent is a mandatory step and that management agencies have a regulated response time (generally 30 days) to validate or refuse the request, provided that the file submitted by the tenant is complete.

These cantonal rules also specify the calculation methods for the rebilling of heating and hot water charges, to avoid frequent disputes at the end of the year. If you reside in the canton of Vaud or another canton with specific joint rules (like Geneva), take the time to consult official local documents or contact the cantonal section of ASLOCA to ensure total compliance.

In conclusion, subletting in Switzerland in 2026 remains a wonderful opportunity to monetize your spare space or find flexible accommodation, provided you play the game of transparency. By respecting tenancy law, obtaining your landlord's written consent, and applying a fair rent, you protect yourself from any legal unpleasantness.
