Commercial lease de-specialisation in Morocco: changing activity under Law 49-16

1. De-specialisation: what exactly are we talking about?

A commercial lease is entered into for a specific activity — the « intended use » of the premises. The tenant undertakes to operate for this activity; in return, they benefit from the protective status of Law 49-16. De-specialisation is the situation where the tenant wants to depart from this intended use: adding new activities, or changing it outright.

The structuring distinction is as follows:

• Partial de-specialisation — the tenant keeps their original activity and adds related or complementary activities to it. Typical example: a bookshop adding stationery and a coffee corner; an optician adding the sale of accessories. The activity stays within the logical continuation of the initial operation.
• Full de-specialisation — the tenant abandons their original activity for a different one, with no relationship of relatedness or complementarity to it. Example: turning a retail business into a restaurant. This transformation, with heavier consequences for the landlord and the building, is more tightly framed.

2. Partial de-specialisation: possible after notifying the landlord

This is the most flexible regime. Under Law 49-16, adding related or complementary activities to the original activity is in principle possible after notifying the landlord— without requiring their prior consent. The logic is clear: as long as the new activity remains in the wake of the initial operation, it does not denature the lease and does not significantly harm the landlord's interests.

Two reflexes are nonetheless essential:

• Notify formally. Notifying the landlord is not a courtesy formality: it opens the possibility, for the landlord, to react and where appropriate to dispute. Confirm the applicable form and time limits with your lawyer.
• Document the relatedness. The landlord may dispute whether the new activity is genuinely related or complementary. The boundary between « complementary activity » and « change of activity » is precisely the ground for litigation. It is better to be able to demonstrate the operational link between the original activity and the one added.

If, conversely, the landlord considers that the change exceeds mere relatedness, the matter shifts to the more demanding regime of full de-specialisation, and the debate may move before the commercial court.

3. Full de-specialisation: a more tightly framed change

Completely changing activity is another matter. Full de-specialisation touches the intended use itself of the premises and may affect the building, its configuration, its market rent, and even other occupants. It is therefore more tightly framed than adding related activities: it requires deeper dialogue with the landlord and, failing agreement, arbitration by the competent authorities under the terms set by the regulations in force.

Rather than citing a deadline or a procedure whose exact contours must be verified case by case, keep the practical reading grid in mind:

• The landlord has a say. A complete change of activity is not a right the tenant exercises unilaterally; it is assessed in light of the interests of the landlord and the building.
• The rent may be reassessed. A more profitable, more « value-enhancing » activity for the location may justify an upward review of the rental value (see section 4).
• The written agreement is king. In practice, securing a full de-specialisation almost always passes through a clear amendment to the lease, negotiated — and quantified — upstream.

For the precise terms (form of the request, time limits, remedies), turn to your lawyer or adviser: these are points settled in light of your contract and the texts in force, not by approximation.

4. The real stake: the impact on rent and rental value

The debate over de-specialisation is rarely purely legal. In the background, there is almost always a question of value. Changing or broadening the activity shifts the use of the premises — and therefore their rental value.

• For the landlord, a more profitable activity, or one more demanding in usable floor area, may justify a rent reassessment. De-specialisation is one of the factors taken into account when setting or reviewing the rent under Law 49-16.
• For the tenant, broadening the possible activities may strengthen the appeal and value of the leasehold right — an intangible asset they may assign. But if the operation triggers a rent increase, the gap between contractual rent and market rent narrows, and the value of the leasehold right may, on the contrary, decrease.

This trade-off is not settled by intuition. It is quantified: market rent of the original activity, market rent of the intended activity, and value of the leasehold right under each scenario. This is precisely what an independent appraisal documents.

5. De-specialisation and the leasehold right: what it changes on assignment

The leasehold right is an intangible element of the business goodwill, on the same footing as clientele, custom and equipment. Its assignment is free: the tenant may assign their leasehold right, it being specified that notifying the landlord is required where the leasehold right is assigned separately from the rest of the goodwill. The nature of the authorised activity bears directly on this value.

A lease whose intended use has been broadened by a partial de-specialisation is often more attractive on resale: the buyer of the goodwill has a wider operating margin. Conversely, a lease whose de-specialisation has caused a significant rent increase may see the value of its leasehold right compressed. For an investor acquiring a goodwill or a portfolio, this angle is central: the valuation of the leasehold right and the exact scope of the authorised use must feature in the due diligence.

6. Private appraisal: a negotiation tool, not a court decision

Let us state it clearly to avoid any misunderstanding. A private appraisal — the one you commission yourself, tenant or landlord — is a decision-support and amicable-negotiation tool. It documents a value, supports a position, secures an amendment. It is nota court decision and is not « binding » on the other party. It helps you support your position with third parties.

In the event of litigation brought before the commercial court — persistent disagreement over the rent after de-specialisation, dispute over the related character of an activity — it is the judge who assesses and, where appropriate, appoints a court-appointed expert. The two logics are complementary: a solid private appraisal report, drawn up upstream, is often what makes it possible to avoid litigation, or to approach it with a file already built.

7. Our practical reading: tenant and landlord

• You are a tenant and want to broaden your activity? First check with your adviser whether the new activity is genuinely related or complementary (partial de-specialisation) or whether it is a complete change (full). Notify the landlord in due form, and anticipate the rent impact with an appraisal.
• You are a landlord and receive a notification? Examine whether the added activity remains in the wake of the initial intended use. If it increases the rental value, this is the moment to objectify a possible rent reassessment — with a report, not an intuition.
• You are an investor or agent? The authorised use and its scope (de-specialisation already carried out or not) are among the elements that make or break the value of a goodwill. Integrate them into the due diligence and the valuation of the leasehold right.

8. FAQ

Note: De-specialisation of commercial leases falls under Law 49-16 (leases for commercial, industrial or craft use). The exact terms of notification, the time limits and the remedies must be verified in light of your contract and the regulations in force — confirm your situation with your lawyer or notary. A private appraisal is a decision-support and amicable-negotiation tool, not a court decision.
