2026 Student intake in Switzerland: The boom in intergenerational housing amid shortages

Finding a roof over your head as the university semester approaches has always been a significant challenge, but searching for Swiss student housing 2026 now feels like a real obstacle course. Faced with inflation, the continuous rise in rents, and the scarcity of available studio apartments in large 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 seeing a true transformation in lifestyles, where intergenerational cohabitation and homestays are no longer emerging as default choices, but as sustainable, affordable, and deeply human solutions. Here is a breakdown of a trend that is reshaping the student housing landscape in Switzerland for the 2026 academic year.

The Swiss housing shortage: an alarming reality for the 2026 semester

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) management, the Swiss housing shortage is worsening significantly for the 2026 semester. Experts anticipate that this structural crisis will continue, with no rapid improvement on the horizon, due in particular to the slowdown in new housing construction and the 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 at around 0.34%, making the search for even a simple studio nearly 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 applicants for the slightest apartment viewing.

Faced with this reality, the consequences for students are heavy: intense stress as the start of the semester approaches, accepting substandard or overpriced housing, or even being forced to move significantly further away from campuses, thereby considerably lengthening daily travel 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 solidarity-based alternatives, based on optimising existing built space, make perfect sense.

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 flown 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 solution that is gaining appeal

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 spare 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 small services. It is a model based on mutual aid, mutual respect, and sharing, which is increasingly appealing to more and more Swiss people.

This model brilliantly addresses a double societal problem. On one hand, it offers affordable, comfortable, and reassuring housing to students who are struggling to find accommodation. On the other hand, 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 exchange, and often allows seniors to stay in their own homes for longer and in better conditions.

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

Among the initiatives that perfectly illustrate this craze in Switzerland, the '1h per m² - A student under my roof' programme, 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 pittance, 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 15-square-metre room, 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 and 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 is 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 advantages for hosts and tenants

For a student who opts for a homestay for the semester, the financial advantages are massive. In cities where a studio is rarely rented for less than 1,000 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 usually includes utilities (water, electricity, internet), thus avoiding 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 at night brings an immense sense of safety. 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 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 agreement, 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 keystone of a successful intergenerational shared housing arrangement.

Homestay for the semester: user guide and Swiss legal framework

Welcoming a student into your home cannot be improvised, especially from a legal point of view. If you are a tenant of your home (which is the case for a vast majority of the population in Switzerland), the law allows you to sublet a room, but under certain strict conditions that must be respected to avoid any dispute with your property management agency or landlord.

According to Swiss law (Code of Obligations), a tenant who wishes to sublet 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 conditions of the sublet to them, if these conditions are abusive compared 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 one can add a fair contribution to utilities (electricity, heating, internet) and a slight surcharge (usually between 10% and 20%) if the room is rented furnished.

Here is a concrete use case to fully understand. Imagine you are renting a 100 m² apartment in Lausanne for 2,000 CHF per month, utilities included. You wish to sublet a 15 m² furnished room to a student. The room represents 15% of the total surface 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 fair. 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 room in your home also involves tax and administrative obligations that should not be overlooked. In Switzerland, income derived from renting or subletting a room constitutes taxable income. As such, it must mandatorily be declared in your annual tax return, under the heading of real estate income or other income, according to the directives of your canton.

However, it is important to note that you can deduct from this income the expenses related to this rental (proportional share of your own rent if you are a tenant, maintenance costs, furniture depreciation). In most cases, if you follow the rule of no abusive profit, the taxable net profit will be nil or very low, which will not significantly impact your overall tax burden.

A major point of vigilance concerns seniors who receive Supplementary Benefits (PC) to the OASI/DI. It is crucial to know that the income received from renting a room can be taken into account in the calculation of your determining 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 office before you get 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 formalise the agreement with a written contract. This contract must specify the rent amount, included utilities, the 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 beautiful human adventure with complete peace of mind for the 2026 semester.
