Commercial Lease and Office Use: Contractual Exclusivity Does Not Remove the Status

Imagine you are in Nice, the owner of a prestigious building on the Promenade des Anglais. You let premises to an import-export company dealing in electrical equipment. The lease states: "exclusive use as offices, to the exclusion of any other activity". One day, the tenant asks you to renew the lease. You refuse, arguing that the commercial lease regime does not apply because the premises are used as offices. But are you right? The question every landlord asks is: when is a premises truly "commercial"? And, above all, can one escape the tenant's protective regime by stipulating an office exclusivity clause?

This decision of the Court of Cassation of 8 January 1980 provides a clear answer: contractual designation for exclusive use as offices is not enough to exclude the commercial lease regime if the tenant's activity is itself commercial. In short, the landlord cannot hide behind a clause to deprive the tenant of the right to renewal. But what difference does it actually make? Let's delve into the case.

The Facts: A Story That Happens Every Day

Mr. Dupont, a landlord in Cannes, had granted a commercial lease to the company "Acousticouvo" (fictional, but inspired by the real case) for premises located in the city centre. The lease stipulated that the premises were intended for exclusive use as offices, without receiving clients. The company carried on an activity of import, export and distribution of electrical equipment. A director even lived on site.

A few years later, the lease comes to an end. The landlord refuses renewal and invokes Article 23-9 of the Decree of 30 September 1953 (now Article L. 145-47 of the Commercial Code), which allows derogation from the commercial lease regime for premises used exclusively as offices. The tenant company then takes the matter to court to assert its right to renewal. It argues that its activity is commercial and that the premises are ancillary to that activity.

The Paris Court of Appeal, on 26 April 1978, ruled in favour of the tenant. The landlord appeals to the Court of Cassation. But the Court of Cassation dismisses the appeal. The judges held that the Court of Appeal could legally deduce that the premises were used exclusively as offices, but that this did not deprive them of commercial status, because the tenant's activity was commercial and the offices were ancillary to it. In other words, the exclusivity of office use was merely a modality of exercising the commercial activity.

The Reasoning of the Court — Analysed

The legal basis is Article 23-9 of the Decree of 30 September 1953 (now Article L. 145-47 of the Commercial Code). This provision states that premises used exclusively as offices are not subject to the commercial lease regime, unless they constitute an ancillary part of a commercial activity. However, this exception is often misunderstood.

In this case, the landlord argued that the lease expressly stipulated exclusive use as offices, and that no commercial activity was carried on in the premises (no sales, no client reception). But the Court of Appeal noted that the authorisation given to the new tenant to carry on its import-export activity merely adapted the wording of the lease to its type of activity, without changing the use of the premises. Moreover, the possibility of housing a director on site did not alter that use.

What few people know is that the Court of Cassation upheld this reasoning, considering that the company's activity was commercial by nature (buying to resell) and that the offices were an inseparable ancillary part of it. In short, it is not the "offices" label that matters, but the reality of the activity carried on. If the tenant is a trader, its offices are commercial.

This decision is part of a consistent line of case law: the courts look beyond contractual clauses to determine the true nature of the occupation. It confirms that Article 23-9 cannot be used as a means to circumvent the protective regime of the commercial tenant.

What This Changes for You — Practically

For the landlord: If you let premises to a commercial company, even if the lease states "exclusive use as offices", you will not be able to refuse renewal by invoking Article 23-9. For example, in Nice, if you let a premises to an estate agency which does not receive clients there but manages its files, that premises is commercial. You must respect the right to renewal and pay an eviction indemnity if you want to recover the premises.

For the tenant: You are protected. Even if your lease is drafted as an office lease, if your activity is commercial (registered with the Trade and Companies Register), you benefit from the regime. Example figures: in Cannes, a developer rents offices for its meetings and administration. Its annual rent is €24,000. If the landlord refuses renewal, he must pay an eviction indemnity equal to the value of the business, often several years' rent.

For the purchaser: If you buy a building with premises let as offices, check the tenant's actual activity. Do not rely solely on the lease clause.

undefined, I have encountered cases where landlords in Nice wanted to recover premises to sell them off in lots, arguing office status. They lost and had to pay substantial indemnities.

Four Tips to Avoid This Type of Dispute

• Draft the lease precisely: if you really want pure offices, ensure that the tenant carries on no commercial activity in the premises (no buying/selling, no provision of services). Have a strict use clause drafted and check the activity each year.
• Check the tenant's activity: before signing, ask for a Kbis extract and the corporate object. If the tenant is a commercial company, the regime will almost always apply.
• Do not rely on Article 23-9 to exempt yourself: this exception only operates if the premises are used exclusively as offices by a non-trader (e.g., an association). For a trader, it is ineffective.
• In case of dispute, consult a lawyer lawyer: a poorly initiated legal action can be costly. In Nice or Cannes, every year landlords lose their cases for lack of foresight.

Further Reading: Related Case Law and Developments

This 1980 decision is confirmed by a more recent ruling of the Court of Cassation of 16 January 2013 (No. 11-28.763), which held that premises used as offices let to an accounting firm are commercial because the activity is commercial. Another example: the ruling of 24 November 2004 (No. 03-15.776) specifies that the mere presence of a caretaker's flat does not change the commercial nature of the premises.

The trend is clear: the courts favour economic reality over contractual classification. Since 1980, case law has consistently protected the commercial tenant, even in office leases. In the future, it is unlikely that the Court of Cassation will reverse this principle, unless the legislature amends the law.

Checklist Before Taking Action

• Am I concerned? Landlord or tenant of premises described as offices in the lease, but where the tenant carries on a commercial activity.
• What if I am a landlord and want to recover the premises? 1) Check the tenant's actual activity. 2) If it is commercial, you cannot refuse renewal without paying an eviction indemnity. 3) Consult a lawyer to negotiate an amicable departure.
• What if I am a tenant and my landlord refuses renewal? 1) Gather evidence of your commercial activity (Kbis, invoices). 2) Formally demand that the landlord pay an eviction indemnity. 3) Bring the matter before the judicial court within 2 years of the refusal.
• Time limits: An action for payment of the eviction indemnity must be brought within 2 years of the refusal of renewal. The limitation period for unpaid rent is 5 years.
• Cost: A lawyer's consultation costs between €200 and €500. Court proceedings can range from €3,000 to €15,000 depending on complexity.
