2026 rent controls: What hosts need to know

As the student intake approaches, a question is on many landlords' lips: how to adapt to the new 2026 rent control measures? Faced with the housing crisis hitting major French cities hard, public authorities have decided to toughen their stance and extend the zones subject to rent caps. For many landlords, these new regulations may seem worrying, complex, or even discouraging. The fear of making a legal error or seeing the profitability of their property collapse is pushing some to withdraw their accommodation from the market. Yet, legal and human-centred alternative solutions exist. At Roomlala, we are convinced that short or medium-term accommodation should not be a legal headache. In this article, we break down the new rules applicable in tight markets, the traps to avoid with standard leases, and we explain in detail why renting a homestay remains a flexible, secure, and perfectly regulated solution for optimising your income while being of service.

Understanding the 2026 rent control: Which cities and which rules?

The rent control mechanism is not new, but its extension for the year 2026 marks a major turning point in housing policy in France. Now, 69 municipalities are affected by this strict measure. Among them are historic metropolises such as Paris, Lille, Lyon, Bordeaux, Montpellier, the Basque Country, and Grenoble. Added to this list are new urban areas where housing tension has become unsustainable, with applications planned and confirmed for cities like Marseille and Annemasse. This expanded map means that a large majority of urban landlords must now deal with this restrictive legal framework.

The principle of the 2026 rent control is based on a precise mechanism: it is forbidden to rent a main residence at a price exceeding a ceiling called the "increased reference rent". This ceiling is calculated per square metre of living space and varies according to several criteria: the neighbourhood (or geographical sector), the building's year of construction, the number of rooms, and whether the property is rented unfurnished or furnished. Prefectural decrees set these amounts each year, and any unjustified excess exposes the landlord to heavy financial penalties, reaching up to 5,000 euros for an individual, not to mention the obligation to refund the overpayment to the tenant.

The objective of this regulation is clear: to protect tenants against abuse, curb real estate speculation, and attempt to resolve the shortage of affordable housing in extremely tight areas. However, for landlords who have invested in property to secure supplementary income or prepare for their retirement, this strict capping can jeopardise the financial balance of their investment. It is therefore crucial to fully understand how this law applies in order to avoid being in breach, while seeking rental models that remain profitable.

Let's take a concrete example to illustrate the impact of this measure. Imagine you own a 20-square-metre furnished studio in the centre of Lyon. Before rent control, you could have rented this property for 650 euros including charges due to strong student demand. With the 2026 rent control, if the increased reference rent for your sector is set at 25 euros per square metre, your base rent cannot exceed 500 euros (excluding charges). Unless you can justify a rent supplement for exceptional characteristics (view of a monument, exceptional terrace), which is very strictly controlled by judges, you are required to respect this ceiling or face legal disputes.

Student rents and short-term leases: The traps to avoid

The 2026 student rent under close scrutiny

With the start of the university year, the temptation is strong to turn to classic student rentals. The student lease, with a reduced duration of 9 months (corresponding to the university year), is often popular with landlords because it allows them to recover the property during the summer for holiday rentals. However, it is essential to understand that the 2026 student rent absolutely does not escape rent control. If your property is located in one of the 69 communes concerned, the 9-month student lease is subject to exactly the same per-square-metre caps as a standard one-year furnished lease.

Inspections are on the rise and tenant associations are increasingly vigilant. A landlord who thinks they can set an arbitrarily high rent under the pretext that the rental period is shorter exposes themselves to severe disappointment. The law is clear: as long as the accommodation constitutes the tenant's main residence during the lease (which is the case for a student over 9 months), the increased reference rent applies automatically. There is no exception related to student status.

Take the case of Sophie, owner of a small apartment in Bordeaux. For the 2026 intake, she decides to rent her property to a business school student via a 9-month lease. Thinking that rent control only applied to long-term leases, she sets a rent 150 euros above the legal ceiling. A few months later, her tenant, informed of their rights, refers the matter to the departmental conciliation commission. Sophie not only had to lower her rent to comply with the law, but she also had to refund the overpaid amounts since the start of the lease. A mistake that cost her dearly in time and money.

The French mobility lease: Not an escape route

Another false good idea often circulates among landlords: using the mobility lease to bypass the rules. Created by the ELAN law, the French mobility lease allows for renting a furnished property for a period ranging from 1 to 10 months to people in a mobility situation (students, interns, professionals on temporary assignment). While this contract offers great flexibility, notably the absence of a security deposit, it constitutes a real trap for landlords who think they have found a legal loophole regarding rent capping.

We must be extremely clear on this point of vigilance: the mobility lease can in no way be used as a trick to escape rent control. This type of contract remains governed by the public order provisions of the 1989 law. Thus, if your property is located in a zone subject to control, the rent of your mobility lease will be subject to the same strict ceilings as any other residential lease. Any attempt to disguise a standard rental as a mobility lease to increase the rent is illegal and easily punishable.

Imagine a landlord in Paris who rents their apartment to an executive on a temporary assignment for 6 months via a mobility lease. The landlord sets a rent of 1,200 euros while the increased reference rent for their property's surface area is 900 euros. The tenant is perfectly entitled to challenge this rent as soon as the contract is signed. The mobility lease is an excellent solution for adapting to the flexibility needs of tenants, but it must be used in strict compliance with the laws in force, without trying to artificially maximise profitability to the detriment of the legal framework.

Homestay regulations: A flexible and legal alternative

Why does homestay avoid the per-m2 cap?

Faced with these growing constraints on entire properties, many landlords are turning to a solution that is both human and advantageous: cohabitation. And this is where a fundamental legal nuance comes into play. Homestay regulations offer a real breath of fresh air. Indeed, renting a homestay escapes the per-square-metre cap imposed by rent control. The legal reason is simple: in this type of configuration, it is materially and legally impossible to define a living area that is exclusively private, since the tenant enjoys not only their room but also the common areas shared with the landlord.

To benefit from this flexibility, one must, however, scrupulously respect the criteria defining a homestay. The rented room must be at least 9 square metres and include a window. It must be decently furnished (bed, bedding, wardrobe, table, chair, lights). Above all, the tenant must necessarily share essential common spaces, such as the kitchen and sanitary facilities (bathroom, toilet), with the landlord. Finally, the property in which the room is located must be the landlord's main residence. If all these conditions are met, the landlord is not subject to the increased reference rent.

Let's take the example of Marc, a pensioner living in a large apartment in Montpellier, a city subject to rent control in 2026. Marc has an unoccupied 12-square-metre room. If he rented an independent studio of this size, his rent would be strictly capped. But by renting this room within his own main residence, with access to his equipped kitchen and bathroom, Marc can set the rent freely. He thus hosts a master's student, secures a significant retirement supplement, and enjoys a reassuring presence, all within a perfectly calm legal framework.

Setting a fair and attractive rent

Although the rent for a homestay is set freely and escapes strict control, this does not mean that the landlord can ask for any price. At Roomlala, we always remind people that pricing freedom must be accompanied by common sense. The rent must remain consistent with the local market to find a taker quickly. A disproportionately high price will drive away serious candidates and could, in the event of a conflict, be reclassified by a judge if the quality/price ratio infringes on the notion of housing decency.

It is important to take into account the services included in the rent. In general, when renting a homestay, charges (water, electricity, heating, internet) are included as a flat rate. The tenant also benefits from the use of the house's equipment (washing machine, household appliances), which represents a substantial saving for them. The rent must reflect this balance: it pays for the private space, the shared use of common spaces, and the supply of utilities, while remaining more affordable than an independent studio for the student or young professional.

Imagine you are offering a room in your home in Grenoble. By consulting listings on Roomlala, you notice that the average for a room of equivalent quality is around 400 euros per month, charges included. If you decide to list your room at 650 euros, under the pretext that you are not subject to rent control, you risk receiving no enquiries. On the other hand, by aligning with market prices, at 420 euros for example, you will very quickly find a trusted tenant. The flexibility of the regulations allows you to optimise your property, but it is the accuracy of your offer that will guarantee the success of your rental.

The benefits of cohabitation with Roomlala for the 2026 intake

The 2026 student intake promises to be tense on the housing front, but it also represents a wonderful opportunity to rethink how we live together. Intergenerational or student cohabitation in a homestay directly addresses the housing shortage in large cities. By opening your door, you are actively participating in the collective effort to house young people, while benefiting from a legal framework that preserves your freedom. It is a win-win relationship where conviviality and mutual aid take precedence over a simple real estate transaction.

At Roomlala, we are committed to reassuring landlords and supporting them in this process. We know that taking the step of welcoming someone into your home can raise questions. This is why our platform is designed to offer you maximum security. You have total control over the choice of your tenant thanks to verified profiles, community reviews, and secure messaging to exchange before validating a booking. Furthermore, our online payment systems guarantee that you receive your rent on time, with no risk of non-payment.

Choosing to rent a homestay via Roomlala means freeing yourself from the administrative complexity linked to the 2026 rent control, while remaining in the strictest legality. We provide you with adapted contract templates, compliant with current regulations, to formalise the rules of communal living and financial terms. Whether you wish to rent for a few weeks to an intern or for the whole university year to a student, we provide you with the tools to do it with peace of mind.

In conclusion, if rent control is shaking up the habits of traditional real estate investors, it should not be perceived as an inevitability. Renting a homestay stands out more than ever as the future solution for landlords wishing to make their available space profitable without suffering the pressure of per-square-metre caps. Don't wait any longer to transform your spare room into a secure source of income and join the Roomlala community for a 2026 intake marked by serenity and sharing.
