The 3-month renewable lease does not correspond to any standard contract provided for by the Construction and Housing Code for a primary residence. This formula, however, circulates in short-term furnished rental listings, often due to confusion with the mobility lease or an intention to circumvent legal minimum durations. Understanding what this practice truly entails helps avoid costly reclassifications for both landlords and tenants.
Judicial reclassification: the real risk of the renewed 3-month lease
A landlord who repeatedly signs 3-month furnished rental contracts with the same tenant risks reclassification as a classic furnished lease of one year. The judge may consider that the property constitutes the tenant’s primary residence, which triggers the automatic application of the protective regime of the ALUR law of 2014.

In practical terms, reclassification imposes on the landlord a contract of one year that is tacitly renewable, a 3-month notice period to terminate (with legal grounds), and a security deposit capped at 2 months’ rent excluding charges. The tenant, on the other hand, benefits from a reduced notice period of 1 month.
This mechanism applies as soon as the property serves as the tenant’s habitual residence, even if the contract specifies a duration of 3 months. The legal qualification of a lease does not depend on the wording chosen by the parties but on the reality of the occupation. To delve deeper into the subtleties of the 3-month renewable lease, it is better to identify in advance the applicable legal framework for each situation.

Mobility lease and 3-month contract: a frequent confusion
The mobility lease is often presented as the ideal solution for renting furnished accommodation for a short period. Its duration can indeed go down to 1 month. But one point blocks any attempt at renewal: this contract is by definition non-renewable and non-extendable.
The total duration of a mobility lease cannot exceed 10 months, even in the case of modification by amendment. Action Logement explicitly reminds us of this. An amendment can shorten or extend the initial period, but the limit remains fixed.
Chaining two mobility leases with the same tenant
This practice is illegal. If a landlord signs a second mobility lease of 3 months with the same occupant for the same property, the contract can be reclassified as a classic furnished lease of one year. The tenant then benefits from all associated protections.
The mobility lease is aimed at specific profiles: students, employees on temporary assignments, people in professional training or relocation. The tenant must justify a mobility reason at the time of signing. Without this justification, the contract is legally fragile from the outset.
Seasonal rental or short-term furnished rental: regulated alternatives
To legally rent a property for periods of 3 months without falling under the residential lease regime, two options exist, each with its own constraints.
- The seasonal rental concerns a property rented to transient clients, for a maximum duration of 90 consecutive days to the same occupant. It falls under the Tourism Code and requires, in most municipalities, a declaration at the town hall (or even a change of use authorization for secondary residences).
- Classified tourist furnished rental follows a distinct tax regime (flat-rate deduction under the micro-BIC regime) but requires official classification of the property and compliance with specific equipment criteria.
- The classic one-year renewable furnished lease remains the default framework as soon as the property constitutes the tenant’s primary residence, regardless of the duration mentioned in the contract.
The choice between these formulas depends on the actual use of the property. An apartment occupied by an employee on regular business trips does not have the same status as a studio rented to tourists for a weekend.
Clauses and security deposit: what changes depending on the type of contract
Financial rules vary greatly from one legal framework to another, and this is often where disputes arise.
In a classic furnished lease (primary residence), the security deposit is capped at 2 months’ rent excluding charges. The landlord must return this amount within a regulated timeframe after the exit inventory.
In a mobility lease, no security deposit can be required. The tenant can, however, provide a Visale guarantee (Action Logement scheme), which covers unpaid rent and damages.

Mandatory mentions of the furnished rental contract
Regardless of the arrangement chosen, certain mentions are required by law for any furnished rental contract for primary residence use:
- Identity of the parties, description of the property and its equipment, amount of rent and terms of revision
- Duration of the lease, start date, amount of the security deposit if applicable
- List of recoverable charges and their payment method (provisions or flat rate)
- Mandatory annexes: exit inventory, technical diagnostics (DPE, natural risks, noise), information notice on the rights and obligations of the parties
A 3-month contract that omits these mentions or does not specify the mobility reason (in the case of a mobility lease) weakens the landlord’s position in case of dispute. The absence of mandatory mentions may be sufficient to reclassify the lease.
3-month renewable lease: in which cases is it really possible
Outside of residential housing, certain professional or commercial leases allow for short durations with renewal. The professional lease (liberal activities) has a minimum duration of 6 years, which excludes 3 months. The classic commercial lease starts at a minimum of 9 years.
The only scenario where a 3-month renewable contract does not pose a major legal problem concerns premises that do not serve as a primary residence: shared offices in sublease with the agreement of the main landlord, or precarious occupation agreements related to a specific event. These arrangements remain marginal and require appropriate legal support.
For a primary residence, the answer is clear: a renewable 3-month lease does not exist under French law. The owner must choose between a one-year furnished lease, the mobility lease (non-renewable), or seasonal rental with its regulatory constraints. Any attempt to create a hybrid contract exposes both parties to legal insecurity that a few well-drafted lines in the correct legal framework can easily avoid.
