New subletting rules in Switzerland: What tenants need to know in 2026

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

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

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

Fortunately for tenants, the Swiss people had the final say. During the federal vote on November 24, 2024, this restrictive amendment was rejected with 51.58% voting no. 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 those of tenants.

Today, in 2026, long-term subletting remains fully legal. There is no duration limit imposed by federal law. If you leave to work abroad for three years, or if you wish to host a student for the entire duration of their bachelor's degree, you are perfectly entitled to do so, as long as you intend to return to the home or if 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 states 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 consent of the landlord (the owner or the property management agency). This point is crucial: you cannot sublet in secret. At Roomlala, we always encourage total transparency. A relationship of trust with your landlord is the key to a successful and stress-free subletting arrangement.

It is important to note that many standard lease agreements still contain a clause that, in principle, prohibits subletting. Legally, in Switzerland, such a general prohibition clause is considered null and 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 out your room legally and obtain the landlord's agreement?

The golden rule: prior written consent

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

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

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

Once the request is sent, wait for the written response from your management agency or landlord. Never settle for a simple verbal 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 landlord's three legitimate grounds for refusal

As mentioned previously, your landlord cannot refuse your subletting request on a mere whim. Swiss housing law is very clear on this: a 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 disclose the conditions of the subletting. If you hide the name of your subtenant or the amount of rent you will be charging them, 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 at their expense (we will return 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 major inconvenience for the landlord. This criterion is evaluated on a case-by-case basis. For example, if you sublet a 20m2 studio to a family of four, the landlord will cite over-occupancy of the premises. Likewise, if the subtenant has notoriously problematic behavior or uses a living 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 Swiss subletting in 2026 is the strict prohibition on making a financial profit. The legislature believes that the principal tenant should not enrich themselves thanks to property that does not belong to them. The rent you ask your subtenant for must therefore cover only their actual costs, without any profit margin.

To calculate a fair rent, you must base it on the principal rent you pay, including charges, and divide it proportionally. The most common and accepted method by management agencies is calculating by square meter. 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 surcharge for depreciation

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 a profit, but a 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 a maximum of 20% of the unfurnished rent of the room. Going beyond this percentage would risk pushing your contract into the category of abusive conditions, justifying a refusal from 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 the event of an audit by the management agency, you will easily be able to justify this surcharge and prove your good faith.

Responsibilities and best practices for peaceful cohabitation

The principal 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 principal tenant, you remain the sole legal and financial entity responsible towards the landlord. This is what 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 principal rent to your management agency. The landlord will not turn against the subtenant; they will turn against you. Likewise, if the subtenant causes damage to the apartment (stain on the parquet, 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 insurance (RC) certificate valid in Switzerland, as well as a security deposit equivalent to one or two months of rent. Always draft a detailed written subletting contract, and carry out a thorough inventory check upon arrival and departure. On Roomlala, our platform facilitates these steps to offer you 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 remain attentive to cantonal specificities. For example, in the Canton of Vaud, new Vaudois rental rules and customs (RULV) came into force on July 1, 2026. These new guidelines further clarify and regulate the practice of subletting at the local level.

The 2026 RULV place heavy emphasis on the obligation to formalize communications. They reiterate that the written consent of the landlord is a mandatory step and that management agencies have a defined 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 re-invoicing 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 in another canton with specific parity 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 free space or find flexible housing, provided you play the game of transparency. By respecting tenancy law, obtaining the written agreement of your landlord, and applying a fair rent, you protect yourself from any legal unpleasantness.
