Commercial lease in Monaco: Law No. 490 and points of vigilance

Published on:
Commercial leases in Monaco are governed by a specific legal framework unique to the Principality. The central reference is Law No. 490 of 24 November 1948 concerning leases for commercial, industrial, or artisanal use, amended in particular by Law No. 1.287 of 15 July 2004. This must not be confused with Law No. 1.490 of 2020, which deals with a different subject: the domiciliation of certain professional activities in State-owned housing.
For a buyer, landlord, or business owner, the challenge is therefore not to mechanically transpose French law, but to verify the exact status of the premises, the activity carried out, the seniority of the business, the clauses of the contract, and the Monégasque texts applicable at the time of the transaction.
To what does Law No. 490 apply?
The status applies to premises and buildings in which a commercial, industrial, or artisanal business is operated under the conditions provided by law. The text notably regulates lease renewal and situations where a disagreement may arise regarding price, duration, or ancillary conditions.
The classification of the premises is decisive. A commercial lease, an office lease, a temporary occupancy agreement, or the simple domiciliation of an activity do not produce the same effects. Before signing anything, it is therefore necessary to identify precisely the legal regime to which the premises are subject.
Lease renewal: a central point
Law No. 490 organises the renewal of leases for premises in which a business has been operated for at least three consecutive years, subject to the conditions provided by the text. This seniority should not be interpreted in isolation: the nature of the activity, the business operated, and the contractual situation must be examined as a whole.
When the principle of renewal is accepted but a disagreement remains over the price or other conditions, the law provides for a specific procedure. For an investor purchasing premises that are already occupied, analysing the existing lease and its expiry date is therefore just as important as analysing the location.
Commercial rent review
Rent should not be analysed solely on the basis of a price per square metre. The law allows, under certain conditions, a request for review when the price no longer corresponds to the rental value due to a change in the general economic conditions of the Principality or special conditions affecting the business. The text notably provides for a minimum period of three years from the effective date of the previously fixed price for certain review requests.
The rental value of premises in Monaco also depends on very concrete factors: visibility, pedestrian flow, permitted use, layout, potential extraction, accessibility, commercial environment, and lease characteristics.
Assignment, subletting and change of activity
The clauses relating to the assignment of the lease, the assignment of the business, subletting or change of activity must be reread carefully. An economically interesting transaction can become much less attractive if the planned activity is not compatible with the contractual destination of the premises or if prior authorisation is required.
It is also essential to distinguish between what relates to the lease, the business asset and the administrative authorisations required to carry out the activity. These subjects are linked, but they should not be confused.
Clauses to check before signing
Before any acquisition or taking of a lease, several elements must be verified: the destination of the premises, the duration, the renewal terms, the rent and its revision mechanisms, the security deposit, the allocation of charges and works, insurance, assignment conditions, subletting, authorized works and the consequences of a cessation of activity.
For premises located in a co-owned building, the co-ownership regulations and technical constraints must also be examined. An activity theoretically permitted by the lease may be limited by the characteristics of the building or by other applicable rules.
Buying occupied premises: read the lease before reading the yield
In an investment acquisition, the displayed yield only makes sense after analysis of the lease. It is necessary to understand the remaining term, the level of rent, the revision possibilities, the obligations of the landlord, the solvency of the tenant, the activity carried out and the renewal conditions.
In Monaco, where property values are high and commercial space is scarce, an error in contractual interpretation can have a significant impact on the value of an asset. The study of the lease must therefore take place before any firm commitment.
What role for the real estate agency?
The agency can document the property, centralise the available contractual elements, explain the market context and coordinate exchanges between seller, purchaser, landlord, tenant and legal professionals. However, it does not replace either the notary or the lawyer for the legal analysis of a contract.
MyCrown Estates therefore favours a combined reading of the location, the commercial potential and the rental situation, in order to avoid reducing premises to just their surface area or their facial rent.
Frequently asked questions about commercial leases in Monaco
Does Law No. 490 concern residential leases?

No. Law No. 1.490 of 23 June 2020 concerns the domiciliation of certain professional activities in residential premises belonging to the State. Law No. 490 of 24 November 1948 concerns commercial, industrial or artisanal leases.
Can a commercial rent be revised freely?
No. The revision mechanisms depend on the contract and the applicable legal provisions. Any request must be examined on the basis of the lease and the practical situation.
Should the lease be reread before buying premises?
Yes. For occupied premises, the lease is an essential part of the analysis. It is recommended to have it verified by a Monegasque legal professional before any commitment.
