Tenant Rights & the Brussels Housing Code

Renting in Brussels can feel intimidating when the lease runs to nine years and half the terms are in French or Dutch — but the Brussels Housing Code (Code bruxellois du Logement / Brusselse Huisvestingscode) is strongly on the tenant's side. This guide explains the rights that matter most: how to leave a lease, how much your rent can rise, the état des lieux, who fixes what, and where to get free help.

The two lease types you'll actually meet

Almost every private tenancy in Brussels is one of two contracts. Knowing which one you signed decides your entire exit strategy.

A nine-year term sounds alarming, but it exists to give you stability, not to trap you. You are never locked in — you can always leave on three months' notice. There is also a student lease, capped at 12 months, which the student can end at any time with two months' notice and no penalty.

Ending your lease: notice periods and compensation

This is the section most people get wrong, so here are the exact rules the Housing Code sets out.

If you have a 9-year lease

You can walk away at any point by giving three months' written notice. The only cost is a sliding compensation if you leave in the first three years:

• Leave during year 1 → three months' rent
• Leave during year 2 → two months' rent
• Leave during year 3 → one month's rent
• Leave from year 4 onwards → no compensation at all (still three months' notice)

Send notice by registered letter (lettre recommandée) or bailiff so you can prove the date — the three months runs from the first day of the month after it's received.

The landlord's power to end a nine-year lease is far more limited. They can only cut it short in specific cases: to occupy the property themselves or house close family (six months' notice, and they must name who is moving in); for major renovation or reconstruction, only at the end of the first or second three-year block; or without a stated reason, again only at the end of year 3 or year 6 and with hefty compensation (nine or six months' rent respectively).

If you have a short lease (up to 3 years)

You can end it early at any time with three months' notice and compensation of one month's rent — flat, regardless of when you leave. If you simply want to let it run to its agreed end, either side gives three months' notice before the term with no compensation. Note that new rules apply to short leases signed since recent reforms; if yours predates them, confirm the exact exit terms against your contract.

Rent indexation: how much your rent can rise

Your landlord cannot raise the rent whenever they like. Indexation is tightly controlled:

• It can happen once a year at most, and no earlier than the anniversary of the lease coming into force.

• It follows the official health index (indice santé) — never an arbitrary percentage. The formula is:

  base rent × new health index ÷ initial health index

  The "initial" index is the month before the lease was signed; the "new" index is the month before the anniversary.

• It is not automatic. The landlord must request it in writing, and can only backdate the increase by three months before the month they ask. Miss the window and they lose that time.

• The lease must be registered and a valid EPB energy certificate must exist for indexation to be allowed at all.

For poorly insulated homes (energy rating E, F or G), a correction factor reduces the increase under an adapted formula introduced in October 2023. The exact factor changes over time, so check the current figures on the official page below rather than trusting any number quoted second-hand. You can also verify any proposed increase yourself using Statbel's rent calculator (statbel.fgov.be) — plug in your figures and see if the landlord's maths holds up.

The état des lieux (inventory of fixtures)

The état des lieux is the document that decides whether you get your deposit back, so treat it as seriously as the lease itself.

• Entry inventory (état des lieux d'entrée): a detailed, room-by-room record of the flat's condition, completed before you occupy it or within the first month. It's best drawn up by an expert with the cost split equally between you and the landlord, or jointly by the two of you.
• Exit inventory (état des lieux de sortie): carried out when you move out (within a month), before you hand back the keys. It's compared against the entry version.

Only damage that goes beyond normal wear and tear — and that was recorded at entry — can be deducted from your rental guarantee. Photograph every scratch, stain and appliance yourself and make sure defects are written down. If one party refuses to cooperate, either of you can ask the Justice of the Peace (juge de paix) to appoint an expert.

Who pays for repairs

The Housing Code splits repairs by a fixed legal list that neither party can contract out of. In short: small routine upkeep is yours; anything structural or age-related is the landlord's.

Your responsibility (tenant):

• Servicing and inspecting the boiler
• Chimney sweeping
• Descaling taps, cleaning seals and filters
• Replacing light bulbs and batteries
• Waxing or oiling wooden floors
• Mowing and maintaining the garden
• Anything you damage through negligence

Landlord's responsibility:

• Replacing a defective boiler
• Worn pipework and plumbing
• Roof repairs
• Emptying septic tanks and clearing blocked main drains
• Anything caused by the ageing of the building or force majeure

If a landlord tries to make you pay for a dead boiler or a leaking roof, point to this list — the division is set by law and cannot be overridden by a clause in your contract.

Where to get help

You are not on your own if something goes wrong. Free, official channels exist:

• Joint Rental Commission (Commission Paritaire Locative / CPL) — an independent body that gives a free, non-binding opinion on whether your rent is fair, usually within two months. Email cplsecretariat@sprb.brussels (French and Dutch only).
• Justice of the Peace (juge de paix) — the small local court with exclusive jurisdiction over rental disputes; its rulings are binding. This is where a rent review or a deposit dispute is ultimately settled.
• Front-line legal aid (aide juridique de première ligne / eerstelijnsbijstand) — free legal information and an initial opinion, open to everyone via the Commissions for Legal Aid.
• Tenant unions (syndicat des locataires / huurdersbond) — membership organisations that advise on your specific contract and can write to your landlord on your behalf.
• Brussels Housing / be.brussels — the Brussels-Capital Region's official housing administration and the authoritative source for every rule above.

Common problems and fixes

• "You signed a 9-year lease, so you can't leave" → False. You can leave any time on three months' notice; from year four you owe nothing.
• Landlord raises the rent by a random percentage → Only health-index indexation is legal, once a year on the anniversary, requested in writing. Recalculate with Statbel's tool and refuse anything above it.
• Landlord backdates a big indexation → Retroactivity is capped at three months before the written request. Older increases can't be clawed back.
• No état des lieux was done → Insist on one within the first month. Without it, the law presumes you received the flat in good condition, making your deposit easier to withhold.
• Landlord bills you for a broken boiler or the roof → Those are the landlord's by law. The repair split can't be altered by your contract.
• Rent looks more than 20% above the reference rent → Ask the Joint Rental Commission for a free opinion, then the Justice of the Peace if needed.
