Reform of residential leases in Wallonia (Autumn 2026): The new benefits for shared housing

Faced with the growing shortage of student rooms and general pressure on the property market, the Walloon Region has decided to take matters into its own hands. This autumn, the highly anticipated Wallonia 2026 tenancy reform comes into force, bringing with it a breath of clarity and modernisation for both hosts and tenants. At Roomlala, we know how daunting it can be to start renting out part of your home. Between fears related to legislation, doubts about taxation and questions about security, taking the plunge requires being well-informed.

However, renting out an unoccupied room has never been more relevant. Not only are you meeting an urgent societal need, but you are also securing a significant supplementary income. This new Walloon regulation has been designed specifically to regulate, secure and encourage shared housing. Whether you are considering a traditional shared housing arrangement or a homestay, we offer a comprehensive breakdown of these legal developments to help you get started with complete peace of mind.

Deciphering the Wallonia 2026 tenancy reform: What is changing in practice

Housing policy in Wallonia is undergoing a major transformation at the end of 2026. The objective of the regional authorities is twofold: to simplify administrative procedures for hosts and to guarantee quality housing for tenants. This institutional and legal restructuring is profoundly changing day-to-day rental management.

The creation of the Walloon Housing Agency (AWH)

One of the cornerstones of this reform is the establishment of the brand-new Walloon Housing Agency (AWH). No more administrative maze! The AWH becomes the one-stop shop for all questions relating to housing in Wallonia. It is supported by 14 local Housing Centres spread across the Walloon territory.

For you, as a host, this means much easier access to information. Do you want to check if your property meets health and safety standards? Do you need help understanding renovation grants before welcoming a tenant? These local centres are designed to support you. At Roomlala, we welcome this initiative, which reassures hosts and professionalises the peer-to-peer rental sector.

Guaranteed registration and tenant protection

A crucial point of the reform concerns registration (domiciliation). From now on, the law is clear: in Wallonia, any clause in a tenancy agreement prohibiting the tenant or housemate from registering at their address is purely and simply illegal and void, provided that the rented property constitutes their main residence.

Let's take a concrete example: you rent a room in Liège to a young worker who establishes it as their main place of residence. You cannot refuse them the right to register there with the local council. This measure aims to combat administrative precariousness. As a host, it is essential to adapt your contracts to be in compliance with this strict rule. This is why, on our platform, we make sure to inform you of these legal obligations to avoid any future disputes.

The new Belgian shared housing rules applied to Wallonia

Shared housing is no longer reserved just for students; it is attracting more and more young professionals, single-parent families and even seniors. To regulate this trend, the Belgian shared housing rules, and more specifically those in Wallonia, have been refined to protect all stakeholders.

The compulsory shared housing pact and the rental guarantee

If you opt for a single shared housing tenancy agreement (where all tenants sign the same document), Walloon law now requires the drafting and signing of a "shared housing pact". This document, annexed to the tenancy agreement, is essential. It governs community life and must include practical aspects such as the distribution of rent, payment of utilities (water, electricity, internet), household organisation and procedures in the event of a housemate's early departure.

Furthermore, the 2026 reform confirms the capping of the security deposit at two months' rent (excluding utilities). No more excessive deposits that blocked access to housing. In addition, the inventory check takes on a new dimension: it must be updated every time a housemate leaves the property and a new one replaces them. This protects you, as a host, by clearly identifying responsibilities in the event of damage at a given time.

The impact of cohabitant status on social benefits

This is a major point of vigilance that we would like to highlight at Roomlala. When several people register at the same address under a shared housing agreement, the Belgian administration may change their social status, moving them from "isolated person" to "cohabitant".

In concrete terms, if you rent your house in Namur to three job seekers, the fact of sharing the same roof and pooling certain expenses (as provided for in the shared housing pact) can lead to a significant reduction in their social benefits (unemployment, CPAS). Although this does not directly affect you as a host, it is your moral duty, and in the interest of a relationship based on trust, to inform your future tenants of this before signing the tenancy agreement.

Homestay in Wallonia: A golden opportunity for hosts

Faced with the complexity of renting out an entire property, homestay in Wallonia is an extremely attractive alternative. Whether it is to bridge the gap in student accommodation or to offer a flexible solution to workers passing through, renting out one or more rooms in your own home offers many advantages, provided you master the legal framework.

Rental permit: When is it really mandatory?

This is often the question that frightens Walloon hosts the most: do I need to obtain a rental permit? The answer depends on the legal structure of your rental. Wallonia is very strict regarding the concept of "collective housing".

• Exemption: If you rent your house to a traditional shared housing arrangement of a maximum of 4 people, and everyone signs a single tenancy agreement, you are generally exempt from the rental permit.
• Obligation: On the other hand, if you have each occupant sign an individual room rental agreement (multiple agreements), or if you host 5 people or more, your property is reclassified as "collective housing". In this case, the rental permit becomes mandatory. It also automatically applies to small dwellings of 28 m² or less.

Obtaining this permit requires compliance with very strict health and fire safety standards. If you choose to rent out several rooms with separate agreements, plan these steps with your local council in advance.

Short-term accommodation and fire safety

Do you prefer flexibility and want to rent out your room for short stays (tourists, interns, workers on the move)? The process is different. In this case, the rental does not constitute the tenant's main residence.

For this type of accommodation, the Walloon Region requires official (and free) registration with the General Commission for Tourism (CGT) of Wallonia. In addition, you must provide a Fire Safety Certificate (ASI) or a Simplified Control Certificate (ACS), proving that your property is equipped with compliant smoke detectors, fire extinguishers and evacuation plans. At Roomlala, we strongly encourage you to comply: it guarantees the safety of your guests and protects you in the event of an incident.

Taxation and security: How to get started with peace of mind with Roomlala?

Generating supplementary income by renting out a vacant room is a great idea to cope with inflation, but you should not neglect the tax aspect. In Belgium, income from property rental must be declared, but the regime varies according to the nature of the rental.

If you rent a furnished room to a student who makes it their main residence, the Belgian tax authorities consider that your rent consists of two parts: a property part (based on the indexed cadastral income) and a moveable part (for the furniture). Moveable income is taxed at a separate rate (often 30%), but you benefit from a 50% flat-rate deduction for expenses. If the rental is purely for tourism, other tax rules apply. We advise you to consult an accountant or the FPS Finance website to optimise your tax return.
