Housing shortage in Geneva and Zurich: The rise of room rentals for cross-border workers

The 2026 Swiss housing crisis is hitting the country's major urban centres hard. As vacancy rates reach historically low levels, finding a place to live has become an uphill battle for young professionals and expatriates. Faced with this real estate emergency, one solution is standing out and gaining unprecedented momentum: homestays. At Roomlala, we see daily how this practice turns a national constraint into a genuine opportunity. For Swiss homeowners and lead tenants, it is a chance to generate secure additional income. For commuters, it is the guarantee of an affordable base. Here is an analysis of a phenomenon that is reshaping the Swiss real estate landscape.

The 2026 Swiss housing crisis: a market under high tension

In 2026, Switzerland is experiencing one of the most severe real estate crises in its recent history. The figures published by the Swiss Federal Statistical Office (FSO) are clear: the national vacancy rate is hovering around 1%, a critical threshold that is paralysing residential mobility. This shortage is even more pronounced in economically dynamic cantons, where demand far outstrips the supply of new builds.

The situation is particularly alarming in major cities. In Zurich, the vacancy rate has fallen below the 0.5% mark, making the search for long-term accommodation in Zurich extremely complex and expensive. In French-speaking Switzerland, Geneva has a vacancy rate of around 0.3%. Queues at apartment viewings are growing longer, and the dossiers required by property management agencies have become draconian, effectively excluding many solvent applicants who do not fit the traditional mould.

The first victims of this hyper-tension are young professionals, students, and, above all, cross-border workers. The latter, who are essential to the Swiss economy, often find themselves forced to endure exhausting commute times due to an inability to find housing near their workplace. It is in this context of stagnation that civic solidarity and ingenuity are stepping in, making homestays an essential and pragmatic alternative.

Renting a room to a cross-border worker: a win-win solution

Meeting an explosive demand for flexible housing

Switzerland currently has more than 410,000 cross-border workers. The canton of Geneva alone is home to nearly 48% of French cross-border workers. These professionals, whether they are nurses, engineers, or office workers, express a massive need for flexible housing. Cross-border worker room rentals from Monday to Friday, for instance, are seeing rapid growth. It allows these workers to reduce their daily fatigue while returning to their families on the weekend.

At Roomlala, we find that flexibility is the watchword of 2026. Unlike a standard long-term lease, which imposes heavy guarantees and a strict commitment, renting a room by the month adapts to probationary periods, fixed-term contracts, or short-term assignments. Cross-border workers thus find an invaluable life balance, avoiding the endless traffic jams at the Bardonnex or Thônex-Vallard customs checkpoints.

Let’s take a concrete example: Julien, a software developer residing in Annecy, has landed a job in Geneva. Rather than spending three hours a day commuting, he rents a homestay room via Roomlala from Monday evening to Thursday morning. This arrangement allows him to be productive at work while preserving his personal quality of life, all for a budget well below that of renting a studio in Geneva.

Additional income in the face of real estate inflation

For Swiss hosts, the financial argument is a major one. With the rising cost of living and increased expenses, the profitability of a homestay in Switzerland provides a real breath of fresh air. Renting out an unoccupied room helps to significantly offset one's own housing costs, whether it is to pay off a mortgage or cover a primary rent.

On average, renting a furnished room in the cantons of Vaud, Geneva, or Zurich can generate between 600 and 1,000 CHF per month, depending on the location and the amenities offered. This additional income, which is regular and secured by platforms like ours, allows many households to maintain their purchasing power in the face of inflation. It is a smart economic approach that optimises existing built space without requiring new construction.

Moreover, the human aspect should not be overlooked. Welcoming a cross-border worker is also about opening yourself up to new encounters and creating social bonds. Many of our users testify to beautiful friendships born from a simple few months of shared living, proving that the financial aspect is often accompanied by true human enrichment.

Legal framework and procedures: what you need to know before you start

The right to sublet guaranteed by Article 262 of the Swiss Code of Obligations

It is natural to have questions about the legality of subletting in Switzerland. Rest assured: in 2026, the practice is fully legal and regulated. In fact, Swiss citizens reaffirmed their support for this right by rejecting, during the federal vote in November 2024, a bill that aimed to drastically restrict subletting. Thus, Article 262 of the Code of Obligations (CO) continues to guarantee the tenant the right to sublet all or part of their home.

However, this right comes with strict duties. The golden rule is transparency: a primary tenant must inform their landlord or property management agency and obtain their prior consent before welcoming a subtenant. The owner can only refuse for valid reasons defined by law, particularly if the terms of the sublease are abusive or if they present major disadvantages for them.

In practice, at Roomlala, we advise you to send a registered letter to your property management agency specifying the exact terms of the rental: the identity of the cross-border worker, the planned duration of the stay, and the amount of rent requested. This proactive approach demonstrates your good faith and prevents any future disputes, ensuring a peaceful experience for all parties involved.

Avoiding abuse and setting a fair price

One of the legal grounds allowing a landlord to refuse a sublease is the realisation of an abusive profit by the primary tenant. Swiss law is very clear on this subject: the purpose of a sublease is not to get rich at the subtenant's expense, but to share housing costs fairly. The rent charged must therefore be strictly proportional to the surface area rented and the use of common areas.

However, case law allows for a legitimate surcharge if the room is rented furnished. As a general rule, a surcharge of 15% to 20% maximum is accepted by the courts to compensate for the wear and tear of furniture (bed, wardrobe, desk), the provision of bed sheets, access to Wi-Fi, or even the use of electricity and heating. It is crucial to detail these elements in the sublease contract.

Here is a clear use case: if you rent a 100 m² apartment for 2,000 CHF per month and you sublet a 20 m² room (i.e., 20% of the surface area), the base rent for the room should be 400 CHF. By adding a 15% surcharge for furniture and internet/electricity costs, a rent of 460 CHF is perfectly fair, legal, and unassailable. It is this fairness that ensures the lasting success of the model.

Taxation and best practices for successful shared living

Tax declaration and financial transparency

The financial side of room rentals does not end with collecting the rent. It is essential to remember that income generated from homestays constitutes taxable income. In Switzerland, tax legislation depends on the canton of residence, but the basic principle remains the same: these amounts must be included in your annual tax return.

We recommend that you keep a simple but rigorous record of the rents received. In most cantons, you can deduct the actual costs associated with the rental (share of expenses, direct maintenance of the room) from this income. Transparency with the tax authorities is the guarantee of a sustainable activity without any nasty surprises. Do not hesitate to consult the specific guidelines of your canton's tax administration (Geneva, Vaud, or Zurich) to optimise your legal deductions.

By using Roomlala, the traceability of your income is facilitated. The history of your bookings and payments received online provides a clear and precise record for your tax return, greatly simplifying your administrative tasks at the end of the year.

The keys to a serene and organised shared living arrangement

Whether it is shared housing in Geneva for a young professional or hosting a cross-border worker, the success of the experience relies on communication. Even before the tenant arrives, it is essential to establish clear house rules. Openly address everyday topics: use of the kitchen, bathroom schedules, household management, or rules regarding guests.

We find that drafting a small cohabitation charter, annexed to the rental agreement, helps prevent 90% of misunderstandings. For example, if you are renting to a cross-border worker who goes home on weekends, specify whether or not the room can be used to store their personal belongings during their absence. Also, clearly define the distribution of space in the fridge and cupboards.

Finally, the Roomlala platform supports you at every step to make this cohabitation secure. From verifying tenant profiles to providing contract templates that comply with Swiss law, we do everything possible to ensure that renting out your room takes place in a climate of absolute trust. Faced with the housing crisis, opening your door is a powerful, profitable, and deeply useful gesture. Ready to take the plunge?
