2026 academic start in Switzerland: The boom in intergenerational housing in the face of shortages

Finding a roof over one's head as the new university term approaches has always been a significant challenge, but the search for student accommodation in Switzerland 2026 now feels like a true obstacle course. Facing inflation, the continuous rise in rents, and the scarcity of studios available in major university cities, students and their families often find themselves helpless. Yet, at 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 establishing themselves not as fallback choices, but as sustainable, economical, and deeply human solutions. A look at the trend that is reshaping the student accommodation landscape in Switzerland for the start of the 2026 academic year.

The Swiss housing shortage: an alarming situation for the start of the 2026 academic year

The situation in the Swiss real estate market has never been this strained. According to the latest statistics confirmed by the management of the Federal Office for Housing (FOH), the Swiss housing shortage is worsening significantly for the start of the 2026 academic year. Experts anticipate a continuation of this structural crisis, with no rapid improvement on the horizon, largely due to the slowdown in the construction of new housing and continuous population growth in urban centres.

The figures 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 is stagnating around 0.34%, making the search for a simple studio almost impossible for a young person on 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 face dozens of other candidates for even the most basic apartment viewing.

Faced with this reality, the consequences for students are heavy: intense stress as the start of term approaches, acceptance of unsanitary or overpriced housing, or even the obligation to move drastically far from campus, thus considerably increasing daily travel times. This housing precarity 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, make perfect sense.

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

Intergenerational shared housing: the solidarity-based solution that is winning people over

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

This model brilliantly addresses a dual societal issue. On one hand, it offers economical, comfortable, and reassuring housing to students who are struggling to find a place to stay. On the other, it helps to break the isolation of the elderly, a silent scourge that affects many seniors in Switzerland. Cohabitation brings life into the house, fosters intergenerational exchanges, and often allows seniors to stay in their homes longer and in better conditions.

The '1h per m² - A student under my roof' programme

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

Let's take a concrete example. If the student occupies a room of 15 square metres, they commit to providing 15 hours of presence or help per month. These hours are by no means related to medical care, but rather to moments of sharing or daily tasks: 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 framework, defined in advance, helps to avoid misunderstandings and ensures a healthy relationship.

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

The concrete benefits for hosts and tenants

For the student opting for a homestay for the start of the term, the financial benefits are enormous. In cities where a studio is rarely rented for less than 1000 CHF per month, finding a homestay for 400 to 600 CHF (or less if services are provided) allows them to halve their housing budget. Furthermore, this generally includes utilities (water, electricity, internet), thus avoiding any nasty surprises at the end of the month.

For the host, beyond the financial aspect which helps to supplement a pension or offset the costs of their home, the human aspect is paramount. Knowing that there is someone in the house in the evening provides an immense sense 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 stories of friendship are born this way each year thanks to these cohabitation arrangements.

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, allows for setting the rules of communal living: schedules, use of shared spaces (kitchen, bathroom), noise management, and arrangements for inviting friends. 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 standpoint. If you are a tenant of your home (which is the case for a large majority of the population in Switzerland), the law authorizes you to sublet a room, but under certain strict conditions that must be respected to avoid any disputes with your property management agency or landlord.

According to 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 inform them of the subletting conditions, if these conditions are abusive in comparison to your own lease, or if the subletting presents major disadvantages for the landlord (for example, overcrowding of the dwelling).

The most crucial point concerns the setting of the rent. Swiss law is very clear: subletting must not under any circumstances generate an abusive profit for the main tenant. The rent charged to the student must be calculated pro rata to the surface area occupied compared to the total surface area of the apartment, to which one may add a fair contribution to utilities (electricity, heating, internet) and a slight increase (generally between 10% and 20%) if the room is rented furnished.

Here is a concrete use case to help understand. Imagine 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 surface area, i.e., the equivalent of 300 CHF of your base rent. By adding access to shared 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 fair. At Roomlala, we support you by providing rental contract templates adapted to the specificities of Switzerland to secure your process.

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

The financial aspect of renting out a homestay room also involves tax and administrative obligations that should not be overlooked. In Switzerland, income derived from the rental or subletting of a room constitutes taxable income. As such, it must be declared in your annual tax return, under the heading of real estate income or other income, according to the guidelines of your canton.

However, it is important to note that you can deduct from this income the costs associated with this rental (proportional share of your own rent if you are a tenant, maintenance costs, depreciation of furniture). 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 benefit from Supplementary Benefits (PC) to the AVS/AI. It is crucial to know that 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 getting started, in order to run a simulation and check the exact impact on your personal situation.

Finally, for the experience to be stress-free, 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 using 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 wonderful human adventure with complete peace of mind for the start of the 2026 academic year.
