Short answer: A Belgian landlord must hand over a home that meets the region''s minimum housing-quality standards — safe, sanitary, with working essential facilities — and must keep it that way during the lease. If your rental is unfit, you don''t have to just accept it: document the defects, notify your landlord in writing (ideally by registered letter), and if nothing changes, report it to the regional housing authority, which can inspect the home and order works or declare it unfit. The exact standards and the procedure differ by region (Flanders, Brussels, Wallonia).

What "fit to live in" means in Belgium

Every region sets minimum quality standards a rental must meet before and during the lease. The themes are consistent across Flanders, Brussels and Wallonia:

• Safety — sound structure, safe electrical and gas installations, working heating.
• Health and sanitation — protection against damp, no serious mould or pest infestation, adequate ventilation and natural light.
• Basic facilities — drinkable cold water (and hot water), a working toilet, cooking facilities, and functioning smoke detectors.

A home that fails these — no working electricity, unsafe wiring, broken windows, serious damp, no heating or hot water — can be judged unfit or, in the worst cases, uninhabitable.

Your landlord''s obligation — at handover and after

This is not optional. Under Belgian law the landlord must deliver the property in a good state of repair and fit for its purpose, and must carry out the major repairs needed to keep it that way throughout the lease. A dwelling that didn''t meet the standards at move-in was, in short, not lawfully rentable — and the problem is the landlord''s to fix, not yours to live with.

Step 1: document everything

Before anything else, build a record:

• Take dated photos and videos of every defect.
• Compare against the inventory of fixtures (état des lieux / plaatsbeschrijving) drawn up at move-in, if you have one.
• Keep a simple written log — what''s wrong, when it started, and any health or safety impact.

This paper trail is what the housing authority and, if needed, the Justice of the Peace will rely on.

Step 2: notify your landlord in writing

Report the defects to your landlord clearly and in writing, and give a reasonable deadline to fix them. A registered letter (aangetekende brief / lettre recommandée) is strongly advised — in Wallonia in particular, proof that you formally notified the landlord is usually required before the authority will act. Keep a copy of everything you send.

Step 3: report to the regional housing authority

If the landlord doesn''t act, escalate to the region''s housing service. The route depends on where you live:

• Flanders — file a complaint with your municipal housing service (Wonen in Vlaanderen). Defects are graded in categories I to III; a category III defect makes the home ongeschikt/onbewoonbaar (unfit/uninhabitable). If the home is declared uninhabitable, you may have a right to (temporary) rehousing.
• Brussels — contact the regional housing inspection, Brussels Housing (inspectiondulogement@sprb.brussels, tel. 0800 40 400). If defects are confirmed, the landlord faces a deadline to carry out works, a home posing an imminent risk can be banned from rental, and landlords can face administrative fines.
• Wallonia — request a habitability inspection (enquête de salubrité) from your municipality if it is accredited, or otherwise directly from the SPW Logement. The inspection report can conclude the home is habitable, habitable with works, or uninhabitable, and is sent to the mayor to act.

What you can ask for

Depending on the situation and region, remedies can include obliging the landlord to carry out the works, a rent reduction, or dissolution of the lease with damages — and where a home never met the standards, the lease can in some cases be declared void. These are decided case by case, usually by the Justice of the Peace, so keep your documentation tight and get advice from a tenants'' association (Huurdersbond / Syndicat des locataires) if you''re unsure.

Keep your paper trail in one place

Everything above turns on documentation — dated defects, the inventory, and proof you told your landlord. If your landlord uses ImmoDesk, ask to be connected: every repair request, photo and message lives in one shared, timestamped record, so your evidence is ready the moment you need it. Invite your landlord to ImmoDesk.
