2026 rent control: Which new cities are taking the step in time for the start of the school year?

Preparing for the start of the academic year is often stressful for students looking for housing, but it also raises questions for hosts eager to rent out their property according to the rules. In this pivotal year, the French real estate landscape is undergoing major changes. With the expansion of rent control in 2026 to new urban areas, the rules of the game are changing for long-term rentals and shared housing. Far from being a hindrance, this regulation aims to balance the market and secure relationships between landlords and tenants.

At Roomlala, we know that deciphering regulatory news is essential to provide you with peace of mind, whether you are a host offering a homestay or a student looking for the ideal shared housing for the new academic year. This article explains in detail the impact of these measures on the student market and reminds you of the many advantages of the mobility lease in France.

2026 rent control: What is concretely changing this year

New cities for rent control

Since the implementation of the Elan law, several large French metropolises have been testing rent capping to combat soaring prices in tight markets. Until now, cities like Paris, Lyon, Lille, Bordeaux, or Grenoble were the leaders of this system. However, the big news this year lies in the inclusion of new municipalities. Indeed, new urban areas are implementing rent control during 2026, thus joining the list of regulated zones.

Among these newcomers, we find key cities for the student market and professional mobility:

• Marseille: the city is taking the step to regulate a market under increasing pressure.
• Annemasse: a border city with Switzerland, it is part of the group due to local real estate inflation.
• Cergy: a major university hub in the Paris region, which is adopting this measure to protect its students.
• Grand-Orly Seine Bièvre: this vast territory in the Paris region is harmonizing its rental rules.

For owners in these sectors, it is now imperative to adapt to this new situation before signing any new lease for the start of the academic year. At Roomlala, we strongly advise hosts located in these new areas to familiarize themselves with the official map of their municipality today. For example, if you own an apartment in Cergy that you wish to rent to a student, you can no longer set your rent price completely freely. Knowing your specific geographic sector becomes the essential first step to offering a compliant and attractive listing.

How does the increased reference rent work?

The central mechanism of this legislation relies on what is called the "increased reference rent." This is a price ceiling per square meter that the owner cannot legally exceed. This amount is not chosen at random: it is calculated according to several very strict criteria. The prefectural decree takes into account the specific geographic sector (often defined by neighborhood), the number of rooms in the housing, the year the building was constructed, and finally the type of rental, i.e., whether the property is rented empty or furnished.

It is crucial to note that these reference rents are re-evaluated each year by prefectural decree. Consequently, a rent deemed compliant in 2025 might require an adjustment for leases signed during the start of the 2026 academic year. At Roomlala, we recommend that you systematically use the official simulators put online by the prefectures or the government. These free tools allow you to check the exact amounts applicable to your situation and avoid any calculation errors when writing your listing.

Let's take a concrete example to illustrate this mechanism. Imagine you are renting a 15-square-meter furnished room in a three-room apartment in Marseille, built before 1946. By using the official simulator of the Bouches-du-Rhône prefecture, you will discover the increased reference rent specific to your neighborhood. If this ceiling is set at 20 euros per square meter, the rent excluding charges for this room cannot exceed 300 euros per month. Respecting this ceiling is the guarantee of a worry-free rental.

What is the impact for shared housing in the 2026 academic year?

Rules applicable to single leases and individual leases

Shared housing for the 2026 academic year promises to be dynamic, but it is not exempt from the new rent control rules. The application of the law differs subtly depending on the type of contract chosen by the flatmates and the landlord. The control fully applies to shared housing with a single lease. In this scenario, the sum of the shares paid by all flatmates must not exceed the increased reference rent applicable to the entire property.

If you opt for individual leases, i.e., a separate contract for each rented room, the rule is similar but applies at the scale of each contract. The rent of each room, relative to its surface area (sometimes including a share of common areas depending on case law), must respect the legal ceiling. This long-term rental legislation aims to prevent the division of an apartment into several rooms from becoming a way to circumvent the global rent capping.

To illustrate, if an owner in Annemasse rents an 80 m² T4 in shared housing with three individual leases, they cannot set the rent for each room at 600 euros if the global increased reference rent of the apartment is 1200 euros. They will have to adjust the rents of each room so that their total does not exceed the authorized ceiling, under penalty of exposing themselves to sanctions. At Roomlala, we take care to inform our community so that each shared housing arrangement takes place in the strictest legality.

Rent supplement: beware of abuses

There is an exception allowing one to exceed the increased reference rent: the "rent supplement." However, the application of such a supplement is strictly regulated. It is exclusively reserved for housing presenting comfort or location characteristics that are objectively exceptional compared to similar properties in the same sector. The law is very clear on this point and case law tends to be increasingly severe towards owners who abuse it.

What is an exceptional characteristic? It could be a huge private terrace with no overlooking neighbors in the heart of the city, an unobstructed view of a historical monument (like Notre-Dame de la Garde in Marseille), or rare luxury equipment. On the other hand, a recently renovated kitchen, the presence of double glazing, or simple proximity to public transport in no way justify a rent supplement, because these elements are already taken into account in the basic calculation or considered as standards of decency.

Tenants, especially students, are increasingly informed of their rights. In the event of a dispute over an abusive rent supplement, the tenant has a deadline to seize the departmental conciliation commission. If the excess is deemed unjustified, the owner is exposed not only to the cancellation of the supplement, but also to administrative sanctions, and the obligation to reimburse the entirety of the overpayment to the tenant. Transparency is therefore your best ally.

The France mobility lease: The ideal solution for students and hosts

Why choose this contract for the start of the academic year?

In this changing regulatory context, the France mobility lease stands out as an extremely flexible and secure option, both for hosts and for tenants. Created by the Elan law, this short-term furnished rental contract (ranging from 1 to 10 months non-renewable) is specially designed for people in a situation of mobility. It is therefore perfectly suited to students, interns, or young professionals in training who are looking for housing for the academic year.

One of the major assets of the mobility lease is its administrative flexibility. Unlike a classic one-year furnished lease, the mobility lease prohibits the owner from requiring a security deposit. To secure the host against the risks of unpaid rent or damage, this contract relies entirely on the Visale guarantee, a free system funded by Action Logement. At Roomlala, we strongly encourage the use of this guarantee which considerably simplifies access to housing for young people.

Concretely, if you are hosting an Erasmus exchange student in Cergy for a semester, the 6-month mobility lease is the tailor-made solution. The tenant does not have to block a large sum for their security deposit, and the host benefits from solid and free coverage. It is a win-win contract that makes the student rental market more fluid, especially during the peak of the September academic year start.

Mobility lease and rent capping: what you need to know

Although the mobility lease is perceived as a short-term contract, it is important to dispel a common misconception: it does not escape long-term rental legislation in terms of price. Indeed, rent control applies in the same way to mobility leases located in tight zones subject to regulation. The fact of renting for only a few months does not authorize you to set a rent higher than the increased reference rent of your municipality.

This measure offers direct protection to students for the start of the academic year, who are often the most vulnerable to high prices in the real estate market. When a student signs a mobility lease in Marseille or in the Grand-Orly Seine Bièvre in 2026, they have the guarantee that their rent respects the legal ceilings. For hosts, this implies showing the same rigor in setting the price as for a classic one-year furnished lease.

Let's take the case of an owner in Lyon (a city already subject to control) who decides to switch from a tourist-style Airbnb rental to a 9-month mobility lease for a student. They will be required to adjust their monthly rate to comply with the increased reference rent of their Lyon neighborhood. At Roomlala, we provide our hosts with resources to help them make this transition serenely while maximizing their occupancy rate over the academic year.

Long-term rental legislation: Towards the end of the experiment?

Rent control as we know it today is the result of a legal experiment resulting from the 2018 Elan law. Legally, this test phase is theoretically scheduled to end in November 2026. This deadline raises many questions among real estate players. Will we see the simple end of the system, or on the contrary, its final permanence in French law?

Currently, government consultations are underway to decide on the extension or the permanence of this measure. The first feedback from local rent observatories shows that the system has helped curb the rise in prices in several large cities, although efforts remain to be made on control and the application of sanctions. The integration of new cities in 2026 is a strong signal that suggests that rent control could be lastingly part of the legislative landscape.

For owners, this transition period may seem uncertain. However, anticipation is the key. By scrupulously respecting the current ceilings, you secure your rental income and protect yourself against potential disputes. In case of non-compliance with the ceiling, the owner is exposed to heavy administrative sanctions:

• Fine of up to 5,000 euros for an individual.
• Fine of up to 15,000 euros for a legal entity.
• Strict obligation to reimburse the entirety of the overpayment to the tenant.

At Roomlala, we follow the evolution of these parliamentary discussions very closely. Our goal is to provide you with reliable and up-to-date information, so that you can rent your property with complete peace of mind. Whether the experiment ends, is extended, or transformed into a definitive law, we will adapt our advice and tools to support you in managing your student rentals and shared housing.
