2026 Mobility lease: The legal framework for renting out your room with total flexibility

As the start of the academic year in September 2026 approaches, the search for accommodation becomes the top priority for thousands of people in France. Whether it is to begin a new university course, start a final internship, or complete a temporary professional assignment, the need for flexibility has never been greater. For hosts, the fear of unpaid rent and the desire to remain in control of their property sometimes hinder the desire to rent. This is where the 2026 mobility lease comes into play. This contract, specifically designed for temporary stays, offers a reassuring and extremely flexible legal framework. At Roomlala, we are convinced that this arrangement is the key to serene and advantageous shared housing. In this article, we delve deep into how this contract works, its recent legal developments, its tax benefits, and why it represents the ideal solution for renting out your homestay room with peace of mind.

What is the 2026 mobility lease and who is it for?

A contract designed for transition

The mobility lease is a short-term furnished rental contract that deviates from the classic rules of a one-year furnished lease. Created by the ELAN law, it was designed to respond to a societal reality: the increasing mobility of students and workers. Unlike a classic 9-month student lease or a 12-month furnished lease, the 2026 mobility lease allows for the duration of the rental to be freely set between 1 and 10 months. This flexibility is a major asset for hosts who wish, for example, to reclaim their guest room for the summer or to host family during the end-of-year holidays.

It is important to note that this contract applies exclusively to furnished accommodation. At Roomlala, we often remind our hosts that the room being rented must comply with a strict list of mandatory equipment (bedding with a duvet, shutters or curtains, storage, lighting, cleaning equipment, etc.). The goal is simple: the tenant must be able to drop off their bags and live comfortably from the very first day, without having to invest in furniture. It is this turnkey dimension that makes this arrangement so successful.

Concrete example: Martine has a large empty room in her Bordeaux apartment from September to March because her son is going on Erasmus. Thanks to the mobility lease, she can rent this room for exactly 7 months. At the end of this period, the contract ends automatically, without her having to justify a complex reason for termination, allowing her to get the room back just in time for her son's return.

Profiles eligible for the temporary rental contract in France

One of the fundamental specificities of the mobility lease is that it is not open to everyone. To be able to sign this temporary rental contract in France, the tenant must essentially justify a situation of mobility at the time the lease takes effect. The law is very clear about the eligible profiles: these are students (in higher education), apprentices, interns, people in professional training, young people on voluntary engagement (civic service), as well as employees on professional transfer or temporary assignment.

As a host, it is your responsibility to request and keep proof of this situation (student card, internship agreement, employer's certificate for an assignment, etc.). Without this document, the contract could be reclassified as a classic furnished lease, causing you to lose all the advantages linked to the short duration. At Roomlala, we facilitate this process by allowing tenants to upload their profile documents, thus offering you immediate visibility on their eligibility.

Concrete example: Lucas, an engineer from Paris, is sent on a temporary assignment to Lyon for 4 months. He is looking for student or young professional accommodation. He provides his future Lyon-based host with a certificate from his company confirming the dates of his mission. The host can then have him sign a 4-month mobility lease in full compliance with the law.

Mobility lease rules: Duration, notice period, and legal novelties

Flexibility of 1 to 10 months (and the 18-month exception)

The golden rule of the mobility lease is its duration: it must be between 1 and 10 months maximum. This duration is set by mutual agreement at the time of signing. An interesting feature of this contract is that it is neither renewable nor tacitly extendable beyond the 10-month limit. If you have signed a 4-month lease, you can, through an amendment, extend it by 2 or 3 additional months, but the total cumulative duration can never exceed 10 months. This strict rule protects the host against the long-term installation of a tenant when they wish to recover their property.

However, the year 2026 brings a major legislative novelty that we would like to highlight. Law no. 2025-1129 of 26 November 2025 introduced a long-awaited exception: it is now possible to extend the maximum duration of the mobility lease to 18 months, but only for accommodation located in employment-oriented residences (residences specifically managed for workers in mobility). Although this exception applies to specific structures, it testifies to the legislator's desire to adapt the law to the reality of the labour market.

Concrete example: You rent a room to a student for 6 months. At the end of this period, she gets an internship in the same city and wishes to stay for 3 more months. You can certainly sign an amendment to extend the lease to a total of 9 months, thus remaining within the legal limit of 10 months.

Notice and departure conditions: who decides?

One of the great principles of the mobility lease rules is the asymmetry of departure conditions, designed to protect the tenant's stability while offering them flexibility. On the tenant's side, the freedom is total. They can decide to leave the accommodation at any time, without having to justify a particular reason. The only constraint is to respect a notice period reduced to one month. This notice period starts from the moment the host receives the registered letter with acknowledgement of receipt, the bailiff's act, or the in-person delivery against signature.

On the host's side, the rule is diametrically opposed. It is strictly forbidden for you to give notice to your tenant before the end date provided in the contract, even if you have an urgent need to recover the room. The landlord is required to respect their commitment until the fixed end date. Once the end date is reached, the contract ends automatically, without you needing to send a notice letter or respect a notice period. The tenant simply needs to return the keys.

Concrete example: A student signs an 8-month lease. After 3 months, they decide to drop out of their studies and return to their parents' home. They send you their one-month notice. You cannot force them to pay for the remaining 4 months. On the other hand, if you are the one who wishes to recover the room after 3 months, you cannot force them to leave before the end of the initial 8 months.

Hosts: Financial security and protection without a security deposit

The strict prohibition of the security deposit

This is often the point that scares novice hosts the most: within the framework of a mobility lease, the law strictly forbids requiring a security deposit from the tenant. This measure was taken to facilitate access to housing for people in mobility, who do not always have the necessary cash to pay for one or two months of rent in addition to the first month and moving-in costs. Any clause in the contract providing for a security deposit would be considered null and void by the courts.

At Roomlala, we understand that this prohibition may generate concern. How to protect oneself against furniture damage or unpaid rent if one holds no sum in reserve? This is a legitimate question. However, the legislator has provided a powerful and totally free alternative to secure hosts, making the security deposit obsolete for this type of temporary rental.

Concrete example: A host asks for a 500-euro deposit cheque from their tenant under a mobility lease to ensure their room will not be damaged. The tenant, knowing their rights, refuses. If they accepted and a dispute arose, the judge would condemn the host for illegal practice. It is therefore crucial to respect this prohibition to remain within the law.

The Visale guarantee: Your anti-unpaid-rent shield

To compensate for the absence of a security deposit, the State, via Action Logement, has put in place the Visale guarantee. This device is the host's best ally within the framework of a mobility lease. It is a rental deposit granted free of charge to the tenant, which covers the payment of rent and charges in case of unpaid rent, as well as repair costs in case of rental damage. It is an extremely robust coverage that protects the landlord much more effectively than a simple month's deposit.

To benefit from it, the process is simple but must be done before the lease is signed. The tenant must make their request on the Visale website and obtain a certified visa. The host then creates their own space on the same site, enters the tenant's visa number, and validates the surety contract. In case of a problem, Action Logement reimburses you quickly and then takes charge of recovering the debt from the tenant. At Roomlala, we strongly encourage all our hosts to require the Visale visa from their tenants.

• Coverage of unpaid rent: Up to 36 unpaid monthly payments covered for the entire duration of the lease.
• Coverage of damage: Coverage up to 2 months of rent and charges for repair costs.
• Total free of charge: Neither the tenant nor the host pays fees for this service.
• Simplicity: All procedures are carried out online in a dematerialized and fast way.

Legal points of vigilance for the 2026 start of the academic year: DPE and reclassification

The DPE 2026 constraints to be strictly respected

Since the implementation of the Climate and Resilience Law, the rental real estate market has undergone profound changes. At Roomlala, we want to alert our hosts to a crucial deadline: in 2026, the rules are tightening considerably. As the mobility lease is subject to the same energy decency criteria as a classic rental, it is now strictly forbidden to have a lease signed for accommodation classified as G in the Energy Performance Diagnosis (DPE). This measure aims to eradicate energy-inefficient properties and guarantee minimal comfort for tenants, particularly during the winter months.

If you own a room in accommodation classified as F, rest assured: you benefit from a reprieve. The rental of these properties remains authorized until 2028. However, we strongly advise you to anticipate insulation or heating work now. In case of non-compliance with this prohibition for accommodation classified as G, the sanctions can be heavy. The tenant is entitled to seize the judge to demand the completion of compliance work at your expense, or to obtain a significant reduction, or even a total suspension of the rent.

Concrete example: Valérie, a host in Lille, was until now renting a small room classified as G. For the start of the 2026 academic year, she can no longer offer this property under a mobility lease. She took advantage of the first semester to install double glazing and insulate the walls, moving her DPE to category E. She can now rent her room in full compliance on Roomlala, even justifying a more attractive rent thanks to the new thermal comfort.

The risk of reclassification as a classic furnished lease

One of the most frequent traps that hosts fall into is the legal reclassification of the contract. The mobility lease is a strict framework. If you do not respect its conditions, the courts will automatically consider that you have signed a classic one-year furnished lease (or 9 months for a student), with all the constraints that this implies (impossibility to recover the accommodation before 1 year, 3-month notice for the landlord, etc.). The first reason for reclassification concerns duration. If your tenant stays in the premises after the 10th month and you accept the payment of an 11th month of rent without saying anything, the lease automatically switches to a standard furnished rental.

The second reason for reclassification concerns furnishing. If the room you are renting does not include all the mandatory elements set by the 2015 decree (for example, if there are missing hobs in the shared kitchen or blackout curtains in the room), the tenant can request reclassification as a bare (unfurnished) 3-year lease! It is therefore essential to carry out a meticulous inventory and a detailed inventory check at the entrance.

Concrete example: A host agrees that their tenant, whose 10-month mobility lease ends on June 30, can stay until July 15 to take their final exams, and charges them half a month's rent. Without knowing it, they have just transformed the contract into a classic furnished lease. The tenant is now entitled to stay for a full year if they wish. To avoid this, they would have had to sign a new, distinct contract, if the law allowed it, or require departure on the agreed date.

By opting for the mobility lease, you choose the lightest contract, most adapted to renting rooms in a home. No need to manage a security deposit to collect and then return, no complicated calculations of deductions from a deposit at the end of the stay. The relationship with the tenant is based on trust and secured by the Visale guarantee.

Furthermore, thanks to our platform, you can easily find verified profiles that perfectly match the eligibility criteria for the mobility lease. International students looking for a base for a semester, interns in search of a comfortable room... You have access to qualified demand. We also provide you with contract templates updated with the latest 2026 regulations, allowing you to finalize your rental in a few clicks, without needing to call on a lawyer.

Concrete example: Jean-Marc offers a room in his house near Nantes. Before, he hesitated to rent for fear of committing long-term. Today, he uses Roomlala to find interns for periods of 3 to 6 months. He generates his mobility leases directly, verifies the internship certificates online, and enjoys the presence of dynamic young people without ever feeling blocked in his home.

Advantageous taxation for furnished rental landlords

Finally, renting a room via a mobility lease allows you to benefit from the very advantageous status of Non-Professional Furnished Rental (LMNP). The income generated by the rental of your room is not considered as classic property income, but falls under the category of Industrial and Commercial Profits (BIC). This tax regime is particularly lenient in France.

If your annual rental receipts do not exceed a certain ceiling (generally 77,700 euros for classic furnished rentals), you can opt for the micro-BIC regime. This gives you the right to a flat-rate allowance of 50% on your rental income. In other words, you will only be taxed on half of the rents collected! If your actual expenses (depreciation of the property, work, loan interest) are higher than this allowance, you can opt for the actual regime, which often allows you to reduce your tax to zero for several years. It is an excellent way to make an unoccupied room profitable while optimizing your tax situation.

Concrete example: By renting his room for 400 euros per month for 10 months under a mobility lease, a Roomlala host receives 4,000 euros over the year. Under the micro-BIC regime, he will only declare 2,000 euros to the tax authorities. It is an additional net income that is particularly interesting to face inflation or finance personal projects as the start of the school year approaches.
