Rent controls 2026: What hosts need to know

As the start of the academic year approaches, one question is on the lips of many landlords: how can we adapt to the new 2026 rent control measures? Faced with the housing crisis that is hitting major French cities head-on, public authorities have decided to get tough and expand the areas subject to rent caps. For many landlords, this new regulation may seem anxiety-inducing, 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 property 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 tense areas and the pitfalls to avoid with standard leases, and we explain in detail why renting a homestay room remains a flexible, secure, and perfectly regulated solution to optimise your income while providing a service.

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

The rent control mechanism is not new, but its extension for 2026 marks a major turning point in housing policy in France. From now on, 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 pressure 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 property as a primary residence at a price exceeding a ceiling known as the "increased reference rent". This ceiling is calculated per square metre of living area and varies according to several criteria: the neighbourhood (or geographical sector), the year the building was constructed, the number of rooms, and whether the property is rented empty 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 property speculation, and attempt to reduce the shortage of affordable housing in extremely tense areas. However, for landlords who have invested in property to ensure an additional 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 so as not to end up in violation, 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 the rent controls, you could have rented this property for 650 euros including charges due to high 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 comply with this ceiling or risk a dispute.

Student rents and short-term leases: Pitfalls to avoid

2026 student rent under close scrutiny

With the start of the university year, the temptation is great to turn to standard student rentals. The student lease, with a reduced duration of 9 months (corresponding to the academic year), is often popular with landlords because it allows them to recover the property during the summer to rent it out seasonally. However, it is essential to understand that 2026 student rent is in no way exempt from rent controls. If your property is located in one of the 69 municipalities affected, the 9-month student lease is subject to exactly the same square-metre ceilings as a standard one-year furnished lease.

Checks are increasing, and tenants' associations are becoming more vigilant. A landlord who thinks they can set an arbitrarily high rent under the pretext that the rental duration is shorter is exposing themselves to severe disappointment. The law is clear: as long as the property constitutes the tenant's primary residence for the duration of the lease (which is the case for a student for 9 months), the increased reference rent applies by right. There is no exception linked to student status.

Let's take the case of Sophie, who owns a small flat in Bordeaux. For the 2026 academic year, 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 set a rent 150 euros above the legal ceiling. A few months later, her tenant, informed of their rights, referred 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 amounts received in excess since the beginning of the lease. A mistake that cost her dearly in time and money.

The French mobility lease: Not a loophole

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 you to rent a furnished property for a period ranging from 1 to 10 months to people in a situation of mobility (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 cannot under any circumstances be used as a trick to escape rent control. This type of contract remains governed by the public policy provisions of the 1989 Act. Thus, if your property is located in an area subject to rent 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 flat to an executive on a temporary assignment for a period of 6 months via a mobility lease. The landlord sets a rent of 1,200 euros even though the increased reference rent for the surface area of their property is 900 euros. The tenant is perfectly entitled to contest this rent upon signing the contract. 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 seeking to artificially maximise profitability to the detriment of the legal framework.

Homestay rental regulation: A flexible and legal alternative

Why does homestay rental escape 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 in. Homestay rental regulation offers a real breath of fresh air. Indeed, renting a homestay room 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 an exclusively private living area, since the tenant enjoys not only their room but also the common areas shared with the landlord.

To benefit from this flexibility, you must, however, scrupulously respect the criteria defining a homestay. The room rented must be at least 9 square metres and include a window. It must be decently furnished (bed, bedding, wardrobe, table, chair, lighting). Above all, the tenant must necessarily share essential common spaces, such as the kitchen and sanitary facilities (bathroom, WC), with the landlord. Finally, the property in which the room is located must be the landlord's primary 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 flat in Montpellier, a city subject to rent control in 2026. Marc has an unoccupied 12-square-metre room. If he were renting an independent studio of this size, his rent would be strictly capped. But by renting this room within his own primary residence, with access to his equipped kitchen and bathroom, Marc can set the rent freely. He thus hosts a master's student, ensures himself a significant retirement supplement, and enjoys a reassuring presence, all within a perfectly peaceful legal framework.

Setting a fair and attractive rent

Although the rent for a homestay room 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 tenant quickly. An excessively high price will scare away serious candidates and could, in the event of a conflict, be reclassified by a judge if the quality/price ratio undermines the notion of decent housing.

It is important to take into account the services included in the rent. Generally, when renting a homestay room, charges (water, electricity, heating, internet) are included in a fixed fee. 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 areas, and the supply of utilities, while remaining more affordable than an independent studio for the student or young worker.

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, including charges. 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 yourself with market prices, at 420 euros for example, you will very quickly find a trusted tenant. The flexibility of the regulation 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 academic year

The 2026 academic year 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 shortage of housing in large cities. By opening your door, you actively participate 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 simple property transactions.

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.

Opting for a homestay rental via Roomlala means freeing yourself from the administrative complexity linked to the 2026 rent control, while remaining in strict compliance with the law. We provide you with suitable contract templates, compliant with current regulations, to formalise the rules of communal living and financial terms. Whether you want to rent for a few weeks to an intern or for the entire academic 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 property investors, it should not be perceived as an inevitability. Homestay rental stands out more than ever as the future solution for landlords wishing to monetise their available space without suffering the pressure of per-square-metre caps.
