Frequently Asked Questions — Renting in Belgium

Find answers to the most common questions about renting in Belgium, whether you're a Belgian tenant or an expat.

1. What documents do I need to provide to rent a property in Belgium?

The documents generally requested are:

• Identity card or passport (+ residence permit for non-Europeans)
• Proof of income: last 3 payslips, employment contract, or employment certificate
• Household composition (available from the municipality)
• References from a previous landlord (optional but appreciated)

For expats without a Belgian track record, a Belgian employment contract or employer's certificate is generally sufficient. Some landlords also accept a higher bank guarantee.

2. How does lease registration work?

Lease registration is mandatory and free for primary residence leases.

• Who registers? The landlord is legally responsible for registration.
• Where? At the Legal Security office of the FPS Finance (online via MyRent or in person).
• Deadline? Within 2 months of signing the lease.
• Consequence if not registered? The tenant can leave the property without notice or compensation.

3. What is rent indexation and how is it calculated?

Indexation is the annual adjustment of rent to the cost of living. It is allowed once a year, on the anniversary date of the lease.

Formula:

• The base rent is the one stated in the lease
• The starting health index is that of the month preceding the lease signing
• The new index is that of the month preceding the anniversary

Key points:

• Indexation is not automatic: the landlord must request it in writing
• It cannot be retroactive beyond 3 months
• In Brussels, indexation may be limited or frozen for poorly insulated properties (EPC E, F, G)

4. What is the notice period to leave my property?

The notice period depends on the lease duration and the region:

9-Year Lease (standard duration)

Short-Term Lease (≤ 3 years)

• In principle, the tenant cannot terminate early (unless a contrary clause exists in the lease)
• In Brussels: termination possible with 3 months' notice + 1 month's compensation

The notice period always starts on the 1st day of the month following notification.

5. Do I need to register at the municipality after moving in?

Yes, mandatory. You must register at the population register of your new municipality within 8 working days of moving in.

Procedure:

1. Go to the Population service of your municipality
2. Bring: identity card, lease contract, possibly household composition
3. A neighbourhood officer will come to verify your address (in the following weeks)
4. Your identity card will be updated with the new address

For expats: this registration is also necessary to obtain your national register number.

6. Can the landlord enter my property without my consent?

No. The tenant benefits from the right to privacy and the inviolability of the home.

The landlord can only enter:

• With your explicit consent (preferably in writing)
• For urgent repairs (water leak, fire risk) — and even then, they must notify you
• For viewings by candidates at the end of the lease — on agreed days and times (maximum 2 hours per day, 3 days per week)

If the landlord enters without authorisation, it constitutes a violation of domicile (criminal offence).

7. What should I do if my property has dampness or insalubrity problems?

Steps to follow:

1. Report the problem in writing (email or registered letter) to your landlord
2. Give a reasonable deadline for repairs (2 to 4 weeks depending on urgency)
3. If no response: contact the housing service of your municipality
4. Request an inspection for habitability (free) from your region:
   • Brussels: Regional Housing Inspection Directorate (DIRL)
   • Wallonia: Housing inspection service
   • Flanders: Wonen-Vlaanderen (conformiteitsonderzoek)
5. As a last resort: refer to the justice of the peace to obtain repairs or a rent reduction

Important: never stop paying your rent unilaterally, even if the property is insalubrious. Only a judge can authorise a reduction.

8. How does shared tenancy work in Belgium?

Shared tenancy is regulated differently depending on the region:

BBrussels

• A co-tenancy pact is mandatory (annex to the lease)
• Each co-tenant can give notice individually
• The departing co-tenant must find a replacement (or the other co-tenants assume their share)

WWallonia

• The co-tenancy pact is also mandatory
• Same individual notice rules as in Brussels

VFlanders

• No specific legal framework for shared tenancy
• Standard lease rules apply
• A co-tenancy pact is strongly recommended (but not mandatory)

Tip: Always insist on having a written co-tenancy pact, even in Flanders. It clarifies the distribution of charges, the guarantee, and the departure rules.

9. What are my rights as an expat tenant in Belgium?

As an expat, you have exactly the same rights as a Belgian tenant. Nationality can never be a criterion for discrimination.

Points specific to expats:

• You can sign a lease even without a national register number (it will be added after registration at the municipality)
• The lease can be drafted in the language of your choice (but the version in the language of the region prevails in case of dispute)
• Your employer can act as guarantor if you don't yet have a Belgian banking history
• Diplomatic clauses (early termination in case of transfer) are negotiable but not mandatory

Discrimination prohibited: A landlord cannot refuse your application because of your nationality, ethnic origin, or language. In case of discrimination, contact Unia (Interfederal Centre for Equal Opportunities).

10. What happens if I don't pay my rent?

Progressive consequences:

1. Friendly reminder — The landlord contacts you to understand the situation
2. Formal notice — Registered letter asking you to pay within 15 days
3. Conciliation — The landlord can request free conciliation at the justice of the peace
4. Legal proceedings — The landlord refers to the justice of the peace to obtain:
   • Payment of arrears
   • Termination of the lease
   • Your eviction (with a minimum period of 1 month)

Important:

• An eviction can never take place without a court decision
• The judge often grants payment plans if you are acting in good faith
• Contact the CPAS of your municipality if you are in financial difficulty — they can intervene
• In winter (from 1 November to 15 March), evictions are prohibited in Brussels (winter truce)

11. Can I sublet my property?

General rule: Subletting is prohibited unless the lease expressly authorises it.

Exceptions:

• Partial subletting (a room): authorised if the main tenant keeps their primary residence in the property
• Total subletting: prohibited unless the landlord gives written consent
• Subletting via Airbnb: subject to strict regional regulations (planning permit in Brussels, registration in Flanders)

12. How do I contest an abusive rent indexation?

You can contest the indexation if:

• It exceeds the amount calculated according to the legal formula
• It is requested before the anniversary date of the lease
• It is retroactive by more than 3 months
• In Brussels: the property has an EPC E, F, or G (freeze or limitation of indexation)

Procedure:

1. Verify the calculation on the official FPS Economy calculator
2. Inform your landlord in writing of the error
3. If no correction, refer to the justice of the peace
