Two fundamentally different legal regimes
The commercial lease benefits from strong statutory protection under the Act of 30 April 1951: 9-year minimum, renewal rights (3 x 9 years) and eviction indemnity (1-3 years of rent). The office lease falls under ordinary contract law with no minimum duration, no renewal right and no eviction indemnity. The key distinction is whether the tenant has direct contact with the public.
| Criterion | Commercial lease | Office lease |
|---|---|---|
| Applicable law | Act of 30 April 1951 (mandatory) | Civil Code, Art. 1714 ff. (ordinary law) |
| Minimum duration | 9 years | None (freely agreed) |
| Renewal right | Yes (3 x 9 years) | No (unless contractual) |
| Eviction indemnity | Yes (1-3 years of rent) | No (unless contractual) |
| Target tenant | Trader with public contact | Professional without public access |
| Contractual freedom | Limited | Very broad |
How to determine which regime applies
The key criterion is direct contact with the public (clientele) at the leased premises:
Commercial lease applies when:
- The premises are used for retail, hospitality, or services with walk-in customers
- The tenant is a trader or artisan who receives clients at the location
- The business depends on the location for attracting customers
Office lease applies when:
- The premises are used for professional activities without public access
- The tenant is a liberal professional (lawyer, accountant, consultant)
- The business does not depend on the physical location for customer contact
- The premises serve as back-office, storage, or administrative space
The classification depends on the actual use of the premises, not on the label given to the lease. A lease titled “office lease” for premises where customers are received may be requalified as a commercial lease by the court.
Consequences of misclassification
Misclassifying a lease has significant legal consequences:
If an office lease should have been a commercial lease:
- The tenant can claim the protections of the 1951 Act (renewal right, eviction indemnity)
- The 9-year minimum duration applies retroactively
- Any clause derogating from the mandatory provisions is null
If a commercial lease should have been an office lease:
- The strict rules of the 1951 Act (renewal deadlines, formal requirements) apply unnecessarily
- The landlord may be bound by obligations they did not anticipate
In case of doubt, it is advisable to draft the lease under the commercial regime to benefit from the stronger protections, or to seek legal advice on the correct classification.

Regional specifics
The Act of 30 April 1951 on commercial leases is federal legislation that applies uniformly across Belgium. The office lease falls under the general provisions of the Civil Code, which are also federal.
There are no regional variations in the distinction between commercial and office leases. However, regional urban planning regulations may affect the permitted use of premises (commercial vs. office), which could indirectly impact the applicable lease regime.
