Shared housing in Belgium: a rapidly evolving legal framework
Shared housing is no longer reserved for students. In Belgium, the number of shared households among young professionals, single parents and seniors has surged in recent years. Faced with rising rents, sharing a property has become an essential economic and social solution.
Yet the legal framework for shared housing remains complex. Each Belgian region has its own rules, and the consequences of choosing the wrong type of lease can be severe. This guide explains everything you need to know before taking the plunge.
Shared housing refers to the rental of the same property by several people who do not form a household. Each co-tenant has a private space (room) and shares the common areas (kitchen, bathroom, living room). Couples or families are not considered co-tenants.
Joint lease or individual leases: which to choose?
The joint lease (standard shared housing)
All co-tenants sign a single lease with the landlord. The total rent is stated, and each is responsible for the whole amount if a joint liability clause is included.
Advantages:
- A single contract for the landlord to manage
- Flexibility in the internal allocation of charges
Disadvantages:
- Possible joint liability
- Departure of a co-tenant is complicated
Individual leases
Each co-tenant signs their own lease for their room with a right to use the common areas. This system is growing, particularly in Flanders.
Advantages:
- Each person is only responsible for their own rent
- Independent departure without affecting the others
Disadvantages:
- More contracts for the landlord to manage
- Total rent is generally higher

The joint liability clause and rental guarantee
Understanding joint liability
The joint liability clause means that each co-tenant can be held liable to pay the entire rent if the others fail to pay. It is a protection for the landlord, but a major risk for co-tenants.
With a joint liability clause, if a co-tenant leaves without paying or if the room remains empty, the remaining co-tenants must cover the shortfall. Read your lease carefully before signing and, if possible, negotiate a time limit on this joint liability.
In Brussels, since the 2018 ordinance, joint liability is no longer presumed for leases registered as shared housing leases. It must be explicitly provided for in the contract.
The rental guarantee in shared housing
With a joint lease, the guarantee is generally paid collectively. The total amount cannot exceed the legal maximum (2 months in Brussels and Wallonia, 3 months in Flanders). With individual leases, each co-tenant pays their own guarantee.
Releasing the guarantee is more complex in shared housing. With a joint lease, it is only released at the end of the lease, even if a co-tenant leaves earlier. To learn more about rental management, consult our dedicated page.
Allocation of charges and co-tenancy agreement
Rental charges
Common charges (water, electricity, heating, internet, maintenance) must be allocated fairly. Two systems exist:
- Fixed charges: a set monthly amount, with no annual settlement
- Actual charges: monthly provisions with an annual settlement based on actual consumption
In shared housing, the fixed system is simpler to manage but may disadvantage some co-tenants. The actual settlement is fairer but requires rigorous monitoring.
The co-tenancy agreement
The co-tenancy agreement is a document between co-tenants (the landlord is not a party to it). It governs practical matters:
- Rent allocation: equal shares or proportional to room size
- Charge allocation: per person, per room or according to usage
- House rules: cleaning, noise, guests, pets
- Departure procedure: notice between co-tenants, search for a replacement
- Shared furniture: inventory, each person’s contribution, fate at the end of the tenancy
Draft the co-tenancy agreement before moving in, when relationships are good. A written agreement prevents many future conflicts. Also plan a joint account for charges and a kitty for minor repairs.
Practical tips for successful shared housing
Before signing
- Visit the property with all future co-tenants
- Read every clause of the lease, particularly the joint liability and departure conditions
- Insist on a property inventory detailing each room and the common areas. Our guide on efficient property inventories explains the method
- Take out fire insurance adapted to shared housing
During the tenancy
- Communicate openly about problems before they escalate
- Keep a record of rent and charge payments
- Follow the co-tenancy agreement and revise it if necessary
When a co-tenant leaves
With a joint lease, the departing co-tenant must generally find a replacement accepted by the landlord and the other co-tenants. In Brussels, the landlord cannot refuse a replacement without serious grounds.

Frequently asked questions
-
With a joint lease, all co-tenants sign the same contract and are generally jointly liable for the total rent. With individual leases, each co-tenant signs their own contract for their room and is only responsible for their share of the rent. The joint lease is more common but riskier for co-tenants.
-
No. The joint liability clause must be explicitly provided for in the lease to apply. Without this clause, each co-tenant is only liable for their share of the rent. In Brussels, since 2018, joint liability is no longer presumed for leases registered as shared housing leases.
-
It depends on the type of lease. With a joint lease in Brussels, the departing co-tenant must give 2 months' notice and propose a replacement. If the landlord refuses the replacement without legitimate grounds, the co-tenant is released at the end of the notice period. In Wallonia and Flanders, the rules vary depending on the type of lease chosen.
-
No, the co-tenancy agreement is not required by law, but it is very strongly recommended. This document between co-tenants governs the allocation of charges, communal living rules, the replacement procedure and the fate of shared furniture. It supplements the lease without binding the landlord.
