Professional and commercial leases: choose wisely
Update April 2026 - The choice between professional lease and commercial lease has direct consequences on the duration of commitment, the right to renewal, the revision of the rent and the exit conditions. In practice, properly reading the lease is often worth as much as the amount of rent displayed.
Short answer: the commercial lease provides more protection for the operation of a fund, with a more structured framework and a right to renewal, while the professional lease offers more flexibility but less protection. The right choice depends above all on your activity, your horizon and the real cost of exit.

What difference in principle?
Commercial lease
It concerns premises in which a business or an activity falling under the status of commercial leases is operated. It is the most protective framework when the premises are a strategic asset of the company.
The professional lease
It mainly concerns liberal professions and activities which are neither commercial, nor artisanal, nor industrial. It is frequently found among lawyers, doctors, experts, consultants and certain intellectual professions.
The major differences to know
1. Duration
- Commercial lease: initial term of 9 years, with the option of three-year termination for the tenant in the classic "3-6-9" scheme.
- Professional lease: minimum duration of 6 years.
2. Renewal
The commercial lease opens, under conditions, a right to renewal. The lessor who refuses may have to pay eviction compensation. The professional lease does not give this right to renewal.
3. The rent review
The mechanisms and benchmark indices are not strictly the same. Service-Public recalls the role of the ILC or the ILAT for the commercial lease, and the ILAT or the ICC for the professional lease depending on the wording of the contract.
4. Exiting the lease
The level of rigidity is not equivalent. You must therefore think not only with regard to the entry rent, but also your visibility on the activity, the planned installation duration and the cost of an early exit.
Hayot Expertise advice: before signing, model the full cost of the premises over several years: rent, security deposit, work, charges, taxes, indexation, fees and early exit. The true price of the lease is often seen after signing.
How to choose between the two
The decision depends above all on 4 criteria:
- exact nature of the activity;
- need for long-term protection;
- visibility on growth;
- desired level of flexibility.
When a commercial lease is often preferable
The commercial lease becomes logical if your premises carry a significant part of the value of the operation:
- shop;
- restaurant ;
- office with passing clients;
- activity requiring major developments;
- point of sale whose location determines turnover.
In these cases, the right to renewal and the clarity of the legal framework are often worth more than apparent flexibility at the start of the relationship.
When the professional lease may be more suitable
The professional lease is often more consistent if you are looking for a lighter framework:
- liberal activity;
- firm without stock or structured business assets;
- need for a temporary location;
- uncertain visibility in the medium term;
- desire to keep a simpler exit.
The classic mistake consists of choosing the professional lease only because it seems simpler, then discovering that it protects the place of practice less than we imagined.
Clauses to read before signing
Rent and indexation
The initial rent counts, but the indexation also counts. A "well-placed" premises can become expensive if the indexation clause is poorly calibrated or if the calculation basis is unfavorable.
Charges and taxes
The distribution of charges, work, property tax and maintenance expenses must be reread without approximation. This position often weighs more on the margin than you might think.
The works
It is necessary to check who pays:
- embellishment work;
- upgrades;
- major repairs;
- work related to exploitation;
- output restoration.
The destination of the places
The destination clause is essential. A project that evolves without authorization can create a risk of termination or refusal of renewal.
Transfer and subletting
The commercial lease is often more regulated on the transfer of the fund, but the restrictions vary from one contract to another. The professional lease may also provide for special conditions. We should never assume that freedom will be the same everywhere.
Why the subject also concerns finance
The lease directly influences:
- your break-even point;
- your cash flow;
- your ability to sell the activity;
- sometimes your valuation;
- the duration of return on work. In a file that we reviewed recently, the rent was not the main subject: the real point of tension came from the restoration clause and the early exit. It's common. The lease then becomes a subject of margin as much as of law.
Speed reading chart
| Key point | Commercial lease | Professional lease |
|---|---|---|
| Initial duration | 9 years | 6 years minimum |
| Tenant exit | In principle at the end of each three-year period | At any time with 6 months' notice |
| Renewal | Yes, under conditions | No |
| Eviction compensation | Possible in case of refusal of renewal | No |
| Common indices | ILC or ILAT | ILAT or ICC depending on the contract |
How to avoid an unpleasant surprise
1. Check the real nature of your activity
The applicable status does not depend on your preference, but on the reality of the operation. A contract name does not change the legal nature of the activity.
2. Simulate the cost over 3 to 6 years
It is necessary to include the rent, charges, deposits, work and any exit costs. A single-year simulation often gives a misleading picture.
3. Reread the exit clauses
A lease is never good just because it is "signed quickly". Leave, renewal and termination clauses must be understood before engagement.
4. Anticipate the evolution of the project
The premises must be compatible with the most likely scenario:
- growth of the firm;
- change of zone;
- increase in staff;
- revente ;
- transmission.

Concrete example
A liberal consultant sometimes chooses a professional lease for its flexibility. If, two years later, its activity switches to a more commercial structure with customer reception, storage and employees, the initial premises may become too narrow legally and economically.
Conversely, a business that signs a commercial lease has an interest in protecting its exit, its indexation and its work from the start, because these elements will weigh on profitability later than the headline rent alone.
Frequently asked questions
Does the commercial lease always provide more protection?+
Yes, in most cases. It better protects operations and goodwill, but it also imposes a more rigid framework.
Can you leave a professional lease before 6 years?+
Yes. The tenant can in principle terminate the professional lease at any time, with 6 months' notice.
Does the commercial lease give an automatic right to renewal?+
No, it creates a right to renewal under conditions. In the event of refusal, eviction compensation may come into play.
Which index to choose for indexing?+
The choice depends on the activity and the wording of the contract. In practice, ILC or ILAT are common for salespeople, ILAT or ICC for professionals.
Should you reread the lease even if the rent seems good?+
Yes. The clauses of charges, works, destination, transfer and exit often weigh more heavily than the rent displayed.
