2026 rent control: What hosts need to know

As the new academic year approaches, many landlords are asking themselves one burning question: how can I adapt to the new 2026 rent control measures? Faced with the housing crisis hitting major French cities head-on, public authorities have decided to take a firmer stance and expand the zones subject to rent caps. For many landlords, this new regulation can seem stressful, complex, or even discouraging. The fear of making a legal mistake or seeing the profitability of their property collapse is pushing some to pull their units off the market. However, alternative, legal, and human-centred solutions exist. At Roomlala, we are convinced that short or medium-term accommodation shouldn't be a legal headache. In this article, we break down the new rules applicable in high-demand zones and the traps to avoid with standard leases, and we explain in detail why renting a homestay remains a flexible, secure, and fully regulated solution to optimize your income while providing a service.

Understanding 2026 rent control: Which cities and what rules?

Rent control is not new, but its expansion for 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 like 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 work within this restrictive legal framework.

The principle of the 2026 rent control relies on a precise mechanism: it is prohibited to rent a primary residence at a price exceeding a cap known as the "increased reference rent." This ceiling is calculated per square metre of living area and varies based on several criteria: the neighbourhood (or geographic sector), the year the building was constructed, the number of rooms, and whether the accommodation 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 goal of this regulation is clear: 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 real estate to secure supplemental income or plan for retirement, this strict capping can threaten the financial balance of their investment. It is therefore crucial to fully understand how this law applies to avoid falling into infringement, while seeking rental models that remain profitable.

Let’s look at 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 (a view of a monument, an exceptional terrace), which is very strictly monitored by judges, you are required to respect this cap under penalty of litigation.

Student rents and short-term leases: Traps to avoid

The 2026 student rent under close surveillance

With the university year approaching, the temptation is strong to turn to classic 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 reclaim the property during the summer for seasonal 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 affected municipalities, the 9-month student lease is subject to exactly the same per-square-metre caps as a standard one-year furnished lease.

Controls are increasing, and tenant 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 faces severe disappointment. The law is clear: as soon as the accommodation constitutes the tenant's primary residence during the lease (which is the case for a student over 9 months), the increased reference rent applies automatically. There are no exceptions linked to student status.

Take the case of Sophie, the owner of a small apartment 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 concerned long-term leases, she sets a rent 150 euros above the legal cap. A few months later, her tenant, informed of their rights, contacts the departmental conciliation commission. Sophie not only had to lower her rent to comply with the law, but she also had to refund the excess amounts collected since the beginning 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 circumvent the rules. Created by the ELAN law, the French mobility lease allows for the rental of furnished accommodation for a period ranging from 1 to 10 months for people in mobility (students, interns, professionals on temporary missions). 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 law. Therefore, if your accommodation is located in a zone subject to control, the rent of your mobility lease will be subject to the same strict caps as any other residential lease. Any attempt to disguise a standard rental as a mobility lease to increase the rent is illegal and easily sanctionable.

Imagine a landlord in Paris who rents their apartment to an executive on a temporary mission for a 6-month period 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 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 maximize profitability to the detriment of the legal framework.

Homestay regulations: A flexible and legal alternative

Why does a homestay escape the per-square-metre cap?

Faced with these growing constraints on entire homes, 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 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, however, one must 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, lighting). Above all, the tenant must necessarily share essential common areas, such as the kitchen and sanitary facilities (bathroom, WC), with the landlord. Finally, the accommodation where 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.

Take the example of Marc, a retiree 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 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 welcomes a master's student, secures a significant retirement supplement, and enjoys a reassuring presence, all within a perfectly serene 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 the landlord can ask for any price. At Roomlala, we always remind people that price freedom must be accompanied by common sense. The rent must remain consistent with the local market to find a taker quickly. An exorbitantly high price will drive away serious candidates and could, in the event of a dispute, 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. Generally, when renting a homestay, charges (water, electricity, heating, internet) are included as a flat rate. The tenant also benefits from the use of household appliances (washing machine, 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 professional.

Imagine that you are offering a room in your home in Grenoble. By checking 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 inquiries. On the other hand, by aligning with market prices, for example at 420 euros, you will very quickly find a trusted tenant. The flexibility of the regulation allows you to optimize your housing, 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 tight 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 a simple real estate transaction.

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 chat before validating a booking.

Whether you wish 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 so with peace of mind.

In conclusion, while rent control is shaking up the habits of traditional real estate investors, it should not be perceived as a fatality. Renting a homestay stands out more than ever as the future solution for landlords wishing to monetize their available space without suffering the pressure of per-square-metre caps.
