2026 student start of the school year in Brussels: Everything you need to know about the student lease and shared housing

At the dawn of the September 2026 academic year, the European capital is facing a significant challenge: housing its students. With over 127,000 young people enrolled in higher education institutions in the region and a student housing coverage rate of approximately 30%, the shortage of student accommodation, or "kots," is becoming dramatically acute. In response, shared housing and homestays are experiencing a real boom. However, be careful: renting to a student is not something to be improvised. The Brussels-Capital Region has a very specific legal framework designed to protect both young people and hosts. At Roomlala, we are committed to supporting you in this adventure. Whether you are a host looking to earn money from an unoccupied room or a student in the midst of a search, this article explains the rules of the 2026 Brussels student lease so you can approach this new academic year with complete peace of mind.

2026 Brussels student lease: How exactly does it work?

The student lease in the Brussels-Capital Region is a derogatory rental contract, designed specifically to adapt to the rhythm of academic life. Unlike a classic 3 or 9-year primary residence lease, it offers essential flexibility for both parties. However, for this particular regime to apply, several strict conditions must be met. At Roomlala, we ensure that our users understand these nuances to avoid any reclassification of the contract.

Proof of enrollment: a sine qua non condition

For a rental contract to be legally classified as a student lease, the tenant must imperatively prove their status. They are required to provide the host with proof of regular enrollment in a higher education institution. If the student is still waiting for their results or acceptance, simple proof of an application for enrollment is tolerated at the time of signing.

However, this tolerance has its limits. The tenant has a strict deadline (generally two months after the start of the lease) to provide the final certificate of enrollment. Use case: Imagine you rent your room to Lucas starting August 1st, but his university does not validate his enrollment until mid-September. Lucas must provide you with his provisional enrollment certificate in August, then the final document in September. If the student fails to provide this document, the contract could be reclassified as a classic primary residence lease, thereby subjecting you to much more rigid termination rules.

Contract duration and renewal rules

The Brussels legal framework is very clear regarding the timeframe: a student lease is concluded for a maximum duration of 12 months. This duration is ideal because it covers the entire academic year, including the August examination session. This contract is then renewable for successive one-year periods, under the same rent conditions (excluding annual legal indexation).

There is a crucial point of vigilance that we often remind our Roomlala hosts: what happens if you sign a 10-month lease (for example, from September to June) and neither you nor the student terminates the contract on time? The law stipulates that if a student lease of less than 12 months is not terminated in time, it automatically converts into a one-year lease, thus extending the contract for two additional months that were not initially planned. It is therefore vital to be rigorous about dates and notice periods.

Termination and notice: What are your rights?

The great strength of the legislation surrounding the 2026 Brussels student lease lies in its flexibility regarding termination. Student life is full of unforeseen events: reorientation, internships abroad, or dropping out of studies. The legislator has therefore provided mechanisms for early exit, while protecting the lessor against prolonged vacancy.

From the student tenant's perspective

The student enjoys almost total freedom. They can terminate their lease agreement at any time, without needing to justify a particular reason. To do so, they simply need to respect a 2-month notice period. Unlike short-term classic leases, the student will not have to pay any termination indemnity (the famous penalty months do not exist here).

Concrete example: Marie, a French student, decides in November to stop her studies in Brussels to return to Paris. She sends her notice by registered mail on November 15th. Her 2-month notice will begin on December 1st and end on January 31st. She will only have to pay her rent until that date, without any additional penalty. At Roomlala, we always encourage transparent communication so that the host can anticipate and find a new tenant quickly.

From the host's perspective

The host, on the other hand, is subject to much stricter rules in order to guarantee the student's stability during their school year. The lessor cannot terminate the lease during the year. They can only end the contract at its expiry (generally after 10 or 12 months), subject to a 3-month notice period notified before the end date.

If the host wishes to recover their room to house a member of their own family (a child starting their studies, for example), they must scrupulously respect this 3-month deadline before the expiry of the current lease. This asymmetry of rights is intended by law to prevent a young person from finding themselves homeless in the middle of an exam period. This is why we advise our hosts to set up reminders in their calendar so they do not miss any legal deadlines.

Brussels shared housing rules: When sharing takes precedence over the student lease

With rising rents and an insufficient supply of studios, Brussels shared housing rules is becoming an essential search term. Many students group together to rent large apartments or entire houses. However, it is essential to understand that from a legal standpoint, the shared housing regime often takes precedence over the student lease regime when several tenants sign one and the same contract.

The mandatory shared housing pact

Since the reform of the lease in the Brussels Region, shared housing is strictly regulated. The flagship measure is the absolute obligation to sign a "shared housing pact" as an annex to the main lease. This document, internal to the flatmates, is essential for governing community life and preventing conflicts that could overflow into the relationship with the host.

What must this pact contain? It must detail the distribution of rent between the flatmates, the key for distributing utilities (who pays for water, electricity, internet), the rules of community life, and above all, the management of the security deposit and potential damages. Use case: If three students rent your property and one of them breaks the ceramic hob, the shared housing pact defines how repair costs are assumed internally, thus avoiding the host having to play arbitrator.

The solidarity clause: what you need to know

The other fundamental aspect of shared housing is the solidarity clause. By signing a single lease for a shared housing arrangement, students are generally bound by indivisible solidarity toward the host. This means that if one flatmate does not pay their share of the rent, the lessor has the right to claim the full amount from the other flatmates.

This rule offers maximum security to the host, but it implies a great responsibility for the students. Furthermore, if one of the students wishes to leave the shared housing during the year, they must not only give their notice but also remain liable for the payment of the rent (for a duration limited to 6 months) unless a replacement is found and accepted by the other flatmates and the host. At Roomlala, we offer clear contract templates so that everyone understands their commitments before the keys are handed over.

Renting a student room in Belgium: New 2026 health and safety standards

If you are planning to rent a student room in Belgium, and more specifically in Brussels, you must prepare for a major regulatory change. As of January 1, 2026, new regional minimum quality and health standards for housing come into effect. These standards aim to eradicate "slumlords" and guarantee decent living conditions for all tenants.

These new guidelines impose strict criteria concerning fire safety (mandatory detectors, fire doors in certain buildings), room ventilation to prevent humidity, access to natural light, and minimum surface areas per occupant. For example, a room rented to a student will have to respect a strict volume and minimum surface area, or risk the accommodation being declared unfit for habitation.

There is also a strong emphasis on energy performance (EPC certificate). Hosts will have to ensure that rooms are properly heated and insulated. Example: A host converting their attic to house a student will have to prove that the roof insulation meets 2026 standards and that the access staircase is secure.

We know that these requirements can seem intimidating for individuals who simply wish to rent out a spare room. This is why Roomlala provides its community with detailed guides and compliance checklists. Our goal is to help you add value to your property while strictly respecting Brussels kot legislation, thereby ensuring a rental experience without administrative hassles or legal risks.

Hosting a student with Roomlala: The solution to the shortage
