2026 Student move-in in Switzerland: The boom in intergenerational housing amid shortages

Finding a place to live as the university term approaches has always been a significant challenge, but searching for student housing Switzerland 2026 now feels like an uphill battle. Facing inflation, the continuous rise in rents, and the increasing scarcity of studios in major university cities, students and their families often find themselves at a loss. Yet, in the heart of this unprecedented housing crisis, a glimmer of hope is emerging: solidarity. At Roomlala, we are observing a real transformation in lifestyles, where intergenerational cohabitation and homestays are no longer default choices, but sustainable, affordable, and deeply human solutions. Here is a breakdown of a trend that is reshaping the student accommodation landscape in Switzerland for the 2026 fall term.

The Swiss housing shortage: an alarming situation for the fall 2026 term

The situation in the Swiss real estate market has never been more strained. According to the latest statistics confirmed by the Federal Office for Housing (FOH), the Swiss housing shortage is worsening significantly for the 2026 fall term. Experts anticipate that this structural crisis will continue, with no rapid improvement in sight, mainly due to the slowdown in the construction of new housing and continued population growth in urban centers.

The numbers speak for themselves and illustrate the gravity of the situation. In the country's main university hubs, rental vacancy rates have reached critical levels, well below the natural equilibrium threshold estimated at 1.5%. In Geneva, this rate hovers around 0.34%, making the search for a simple studio almost impossible for a young person with a limited budget. In Zurich, the situation is just as alarming with a rate of 0.48%, while Lausanne fluctuates between 0.4% and 0.6%. For a student, this often means having to compete with dozens of other candidates for even the smallest apartment viewing.

Faced with this reality, the consequences for students are heavy: intense stress as the start of the term approaches, settling for unsanitary or overpriced housing, or even being forced to move far away from campus, significantly increasing daily commute times. This housing insecurity directly impacts the academic success and mental health of young people. It is in this context of urgency that innovative and supportive alternatives, based on optimizing existing built space, take on their full meaning.

At Roomlala, we are convinced that the solution lies partly in already built housing. Thousands of rooms lie empty in apartments or houses occupied by the elderly or families whose children have left the nest. Connecting these unoccupied spaces with student demand is an absolute necessity today to ease the burden on the traditional Swiss rental market.

Intergenerational shared housing: the solidarity solution that is gaining appeal

Faced with the wall of the housing crisis, intergenerational shared housing is emerging as a major and immediate response. The concept is simple: a senior (or a family) with a spare room hosts a student. In exchange for a very moderate rent, or even for free, the student commits to offering a reassuring presence and a few small services. It is a model based on mutual aid, respect, and sharing, which is attracting more and more Swiss people.

This model brilliantly addresses a dual societal issue. On one hand, it offers affordable, comfortable, and reassuring housing to students struggling to find a place to live. On the other, it helps break the isolation of the elderly, a silent scourge affecting many seniors in Switzerland. Cohabitation brings life into the house, fosters intergenerational exchanges, and often allows seniors to continue living at home for longer and in better conditions.

The '1 hour per m² - A student under my roof' program

Among the initiatives that perfectly illustrate this craze in Switzerland, the '1 hour per m² - A student under my roof' program, particularly active in the canton of Geneva and supported by networks like Intergeneration.ch, serves as an example. The principle of this program is ingenious and fair: the student benefits from a room for free or at a very low price, and in return, they dedicate a certain number of hours per month (equivalent to the square footage of their room) to helping their host.

Let's take a concrete example. If the student occupies a 15-square-meter room, they commit to providing 15 hours of presence or help per month. These hours in no way resemble medical care, but rather moments of sharing or daily assistance: sharing a meal, doing some shopping, teaching the senior how to use a computer, taking care of the garden, or simply chatting over a cup of tea. This clear, predefined framework helps avoid misunderstandings and ensures a healthy relationship.

At Roomlala, we facilitate access to this type of arrangement. Our platform allows hosts to precisely detail their expectations in their listing, whether it's a simple rental for rent or a service-exchange arrangement. We provide secure messaging tools so that both parties can get to know each other and ensure their compatibility before committing.

Concrete benefits for hosts and tenants

For the student who opts for a homestay for the new term, the financial benefits are colossal. In cities where a studio rarely rents for less than 1000 CHF per month, finding a homestay for 400 to 600 CHF (or less in exchange for services) allows them to cut their housing budget in half. In addition, this generally includes utilities (water, electricity, internet), thus avoiding bad surprises at the end of the month.

For the host, beyond the financial aspect that allows them to supplement a pension or offset housing costs, the human aspect is paramount. Knowing that there is someone in the house in the evening brings an immense feeling of security. It is also an opportunity to pass on one's experience, discover the culture of the younger generation, and feel useful. Many beautiful friendship stories are born every year thanks to these cohabitations.

To ensure the success of this human adventure, we always recommend establishing a 'cohabitation charter' from the very first days. This informal document, in addition to the rental contract, helps set the rules for shared living: schedules, use of shared spaces (kitchen, bathroom), noise management, and policies for inviting friends over. Transparent communication is the cornerstone of successful intergenerational shared housing.

Homestay for the new term: instructions and the Swiss legal framework

Hosting a student in your home is not something to improvise, especially from a legal point of view. If you are a tenant of your housing (which is the case for a large majority of the population in Switzerland), the law allows you to sublet a room, but under strict conditions that must be respected to avoid any disputes with your property management or landlord.

Under Swiss law (Code of Obligations), a tenant who wishes to sublet a part of their home must obtain the prior consent of their landlord. Rest assured, the landlord can only refuse this subletting in very specific cases: if you refuse to communicate the terms of the subletting to them, if these terms are abusive in relation to your own lease, or if the subletting presents major disadvantages for the landlord (for example, overcrowding of the unit).

The most crucial point concerns setting the rent. Swiss law is very clear: subletting must under no circumstances generate an abusive profit for the main tenant. The rent requested from the student must be calculated pro-rata based on the surface area occupied relative to the total surface area of the apartment, to which you can add an equitable contribution to utilities (electricity, heating, internet) and a slight surcharge (generally between 10% and 20%) if the room is rented furnished.

Here is a concrete use case to understand it well. Imagine that you rent a 100 m² apartment in Lausanne for 2000 CHF per month, including utilities. You wish to sublet a 15 m² furnished room to a student. The room represents 15% of the total area, which is the equivalent of 300 CHF of your base rent. By adding access to common areas (kitchen, living room, bathroom) and the depreciation of the furniture, a rent of 450 to 500 CHF per month will be considered perfectly legal and equitable. At Roomlala, we support you by providing rental contract templates adapted to Swiss specifics to secure your process.

Taxation and social benefits: what you need to know before hosting

The financial aspect of renting a homestay room also implies tax and administrative obligations that should not be neglected. In Switzerland, income derived from renting or subletting a room constitutes taxable income. As such, it must be declared in your annual tax return, under the section for real estate income or other income, depending on the directives of your canton.

However, it is important to note that you can deduct from this income the expenses related to this rental (proportionate share of your own rent if you are a tenant, maintenance costs, furniture depreciation). In most cases, if you respect the rule of non-abusive profit, the net taxable profit will be zero or very low, which will not significantly impact your overall tax burden.

A major point of vigilance concerns seniors who receive Supplementary Benefits (PC) for OASI/DI. It is crucial to know that the income received from renting out a room can be taken into account in the calculation of your qualifying income. Paid cohabitation could therefore, in some cases, lead to a reduction in your supplementary benefits. We strongly advise you to contact your cantonal compensation fund before starting, in order to run a simulation and check the exact impact on your personal situation.

Finally, for the experience to be serene, it is essential to formalize the agreement with a written contract. This contract must specify the rent amount, included utilities, duration of the rental, termination conditions, and the amount of the security deposit. By going through a trusted platform like Roomlala, you benefit from a secure framework: payments are managed online, student profiles are verified, and we provide you with all the necessary documents to start this beautiful human adventure with complete peace of mind for the 2026 fall term.
