2026 rent control: Why renting out a homestay remains advantageous

With autumn 2026 approaching, the French real estate landscape is preparing for a new major turning point. The 2026 rent control measures are generating a lot of buzz, sparking both hope among tenants and a certain apprehension among landlords. Indeed, new urban areas are being added to the scheme, further restricting the pricing freedom of owners of entire homes. Faced with these increasingly strict regulations, many owners are questioning the viability of their investments and looking for legal and profitable alternatives.

At Roomlala, we support thousands of hosts every day who have chosen friendliness and security. We have noticed that faced with legislative inflation, one solution stands out clearly for its flexibility: renting a room in one's primary residence. Far from the constraints weighing on independent studios, this option offers a legal and tax haven, provided that certain rules are respected.

In this article, we will decode the implications of extending rent control, explain in detail why the rent of a homestay room escapes these strict caps, and provide you with all our advice for setting your rate legally while optimizing your tax situation.

Understanding 2026 rent control and its extension in tight housing markets

The rent control mechanism, stemming from the ELAN law, aims to curb the rise in housing costs in sectors where demand significantly exceeds supply. In 2026, this mechanism is extending to several popular urban areas. Cities such as Marseille, Annemasse, Cergy, and the Grand-Orly Seine Bièvre territory are joining the list of municipalities subject to this regulation. If you own an entire apartment in one of these cities, you are now required to respect a maximum reference rent, set by prefectural decree and calculated per square metre.

Concretely, when a property is located in a tight housing market, the landlord can no longer freely set their rent when signing a new lease or a renewal. This measure is intended to protect the purchasing power of households, but it mechanically reduces the rental profitability for traditional landlords. Investors who had bet on small spaces, such as student studios, see their returns capped, which sometimes pushes them to remove their properties from the long-term rental market.

A crucial point adds to the complexity of the situation: the experiment of rent control provided for by the ELAN law is theoretically scheduled to end on November 24, 2026. This legislative deadline creates a zone of uncertainty for many landlords. Will the system be extended, modified, or abandoned? Faced with this legal ambiguity, it is natural to look for housing solutions that are less exposed to political volatility and arbitrary caps.

This is precisely where renting a room in your own home makes perfect sense. At Roomlala, we observe that more and more owners are turning to this solution. It not only allows you to monetize an unoccupied space (such as a child's bedroom after they have left for university), but it also offers a much more flexible regulatory framework, disconnected from the constraints of classic rent caps.

Homestay room rent: An advantageous legal exception

Why homestay rooms escape the rent cap

The great strength of renting a room within your own home lies in its specific legal status. In practice, renting a homestay room escapes the classic 2026 rent control. The reason is purely technical and mathematical: to apply a reference rent per square metre, one must be able to define with millimetre precision the tenant's exclusive living area (Boutin law). However, in the context of shared housing, this is impossible.

When you host a student or a young professional in your home, they rent a private room, but they also enjoy a share of the common areas: the kitchen, the living room, the bathroom, and even the garden. It is legally and physically impossible to quantify exactly this shared surface area to apply a prefectural rate to it. Consequently, the homestay rental regulation leaves you, as the owner, the freedom to set your rent.

Let's take a concrete example. If you live in Marseille (newly subject to control in 2026) in an 80 m2 apartment and you rent out a 15 m2 room, you are not only renting 15 m2. You are offering access to an equipped kitchen, a cozy living room, and a functional bathroom. You can therefore set a flat rate that reflects the overall value of this comfort and associated services, thus offering much better profitability than an independent 15 m2 studio subject to price caps.

This pricing freedom is a major asset. It allows you to adjust your rent according to the actual features of your home (fibre connection, neat decoration, premium location) without being held back by a rigid administrative grid. However, this freedom comes with a responsibility: to offer a fair price that is consistent with the local market to attract serious tenants.

Be careful of reclassification as an independent dwelling

While the freedom to set the homestay room rent is an undeniable advantage, there is one fundamental point of vigilance that should never be neglected. To maintain this protective status, the room must imperatively remain an integral part of your primary residence. The spirit of the law is clear: it is about sharing your own living space.

The major risk for an overly zealous owner is the reclassification of the room as an independent dwelling. If you have set up a bedroom on the ground floor of your house with a totally separate entrance, private sanitary facilities, and an equipped kitchenette, the tax authorities and judges will consider that this is no longer a homestay room, but an independent studio. From that point on, the rules change drastically.

In the event of reclassification, your property immediately falls under classic legislation. If it is located in a tight housing market, rent control will apply retroactively. The tenant could then demand a refund of the overpayment, and you would lose all the tax advantages linked to renting out a part of your primary residence.

At Roomlala, we advise you to maintain the sharing of living spaces. This is the very essence of our platform! Sharing the kitchen or the bathroom is not just a legal obligation to avoid reclassification; it is also an opportunity to create human connections, chat over morning coffee, and live an enriching and secure hosting experience.

Taxation and exemption: Do not confuse rent control with tax ceilings

Exemption ceilings for 2026

It is essential to distinguish between rent control (which falls under housing law and municipal authority) and tax exemption (which falls under the General Tax Code). While you are free to set the amount of your rent, the state nevertheless encourages you to offer moderate rates by offering you an extremely powerful tax incentive: a total income tax exemption on your rental income.

To benefit from this exemption until December 31, 2026, the annual rent excluding charges for the room must remain below a ceiling set by the authorities. Following the update on August 19, 2026, these ceilings are as follows: 215 euros per square metre per year in the Île-de-France region, and 159 euros per square metre per year in other regions.

Let's take a use case to clearly understand. You rent a 12 m2 room in Cergy (Île-de-France). The annual ceiling is 12 m2 x €215 = €2,580. Divided by 12 months, this gives you a maximum monthly rent of €215 excluding charges to pay absolutely no tax on this income. If you rent a 15 m2 room in Annemasse (the provinces), the calculation is 15 m2 x €159 = €2,385 per year, or approximately €198 per month excluding charges.

Please note that these ceilings only concern the rent excluding charges. You can certainly add a fixed charge (for water, electricity, internet) which will be added to this amount. This exemption is an exceptional profitability lever, as a tax-free rent is often worth much more than a high rent that is heavily taxed.

The "cliff effect" at the first euro of excess

This is where the biggest trap lies for unwary owners: the cliff effect. The homestay rental regulation on the tax level does not work in progressive brackets. It is an exemption under strict conditions. If you exceed the ceiling set by tax authorities, even by a single euro, all of your rental income becomes taxable from the very first euro.

Let's go back to our Cergy example. Your monthly ceiling excluding charges is €215. If you decide to rent your room at €220 excluding charges per month, thinking you will earn €5 more, you lose the total exemption. The €2,640 annual total (€220 x 12) will have to be declared in your property income or as industrial and commercial profits (BIC) and will be taxed according to your marginal tax bracket, plus social contributions.

In the end, by wanting to earn €60 more per year, you could end up paying several hundred euros in taxes. It is clearly not worth it. This is why we emphasize this point heavily to our community.

At Roomlala, we invite you to take out your calculators before publishing your listing. Set a rent excluding charges just below the legal ceiling to guarantee your exemption, and adjust your charges to actual costs to cover your expenses. This is the healthiest and most profitable strategy in the long run.

The golden rules of homestay rental regulation in 2026

For your room rental to go as smoothly as possible and strictly respect the legal framework, several imperative criteria must be met. First of all, the room rented must constitute the tenant's primary residence. This is generally the case when you rent to a student for the academic year or a young professional on a work assignment. If you rent by the night for tourism, you switch to the regulations for guest rooms, which involve totally different rules.

Next, the dimensions of the room are strictly regulated by law for reasons of decency. The room must measure at least 9 square metres of living area (Carrez law), with a ceiling height of at least 2.20 metres. Alternatively, the room must have a living volume of at least 20 cubic metres. A windowless room is strictly prohibited for rental.

Finally, the room must be rented furnished, which implies providing the mandatory equipment provided for by law. Your tenant must be able to live, sleep, and eat there properly. You must therefore provide at least: bedding with a duvet or blanket, shutters or blackout curtains for the windows, a table, a chair, storage shelves, and lighting fixtures. Of course, access to the sanitary facilities and the equipped kitchen of your home is an integral part of the contract.

By following these simple rules, you ensure total peace of mind. The 2026 rent control should not be perceived as a burden, but as an opportunity to rethink how you rent. By opening the doors of your home with Roomlala, you choose a friendly, legally flexible, and fiscally very advantageous solution.
