Legal framework: federal + regional
The commercial lease is a federal matter. The law of 30 April 1951 applies uniformly across the entire Belgian territory, including the Brussels Region. There is no region-specific regime for commercial leases, unlike residential leases since 2014.
A commercial lease signed in Brussels follows the same rules as in Liège or Antwerp: 9-year term, right to renewal, indexation framework, eviction compensation.
Brussels regional rules do not directly affect the commercial lease but come into play through urban planning (COBAT), municipal taxation and the Regional Land Use Plan (PRAS).
For the full legal framework: commercial lease pillar.
Brussels commercial market
Brussels is home to approximately 220,000 businesses and enterprises. Rental prices vary significantly:
- Premium districts (Avenue Louise, Grand Sablon): €1,000 to €3,500/m²/year.
- Major shopping streets (Rue Neuve, Chaussée d’Ixelles): €600 to €1,500/m²/year.
- Developing areas (Molenbeek, Anderlecht, Laeken): €200 to €500/m²/year.
The rental amount depends primarily on pedestrian footfall, visibility and the commercial mix of the district.
Real estate agencies in Brussels
Real estate agencies play a central role in the Brussels commercial rental market. They can intervene at several levels: tenant search, premises search, contract negotiation, rent estimation and property management.
Types of agencies:
- Generalists (ERA, Century 21): all property types.
- Commercial specialists (CBRE, JLL, Cushman & Wakefield): large commercial premises.
- Local boutique agencies: strong personal network, in-depth neighbourhood knowledge.
Commissions range between 1 and 3 months’ rent, usually borne by the landlord. Agencies must be IPI-accredited to operate.

Business transfer and assignment in Brussels
A Brussels trader who sells their business also transfers their lease (unless otherwise stipulated). Transfer values in Brussels are among the highest in Belgium.
The transfer involves: sale of the business + lease assignment + registration update. For a commercial lease template: commercial lease PDF template.
Disputes and justice of the peace
Disputes regarding a Brussels commercial lease fall under the jurisdiction of the justice of the peace of the canton where the property is located. Brussels has 14 cantons of justices of the peace. The procedure is accessible, and legal representation is not mandatory.
To challenge a renewal refusal or an eviction compensation amount, sending a registered letter to the landlord is a recommended preliminary step.
