Two minutes versus four months. In Nice, obtaining a registration number takes two minutes online. Obtaining the right to rent takes four months of processing, when it’s still possible. Many owners don’t know these are two different things, and learn this after they’ve bought.
There’s a sentence I hear almost every week. An owner calls Mystralia Conciergerie and tells me: “I have the registration number, so I’m good.”
It’s not good, and it’s not their fault. I manage about twenty short-term rental properties in Nice and I receive four to five requests per month. A significant portion of these owners discover during the call that they don’t have the right to do what they’re already doing. The first conversation is no longer about income or cleaning, but about the right to rent.
The two procedures everyone confuses
The registration number is requested online, on the tourist tax website. The form takes two minutes. You receive your number, you paste it in your listing, everything seems settled. It’s this ease that creates the illusion: a procedure this simple can’t be a mere formality.
Yet it is. The number serves to identify the property and collect the tourist tax. It grants no rights. The right is the change of use authorization.
| Registration number | Change of use | |
| What it’s for | Identify the property, collect tourist tax | Authorize tourist furnished rental |
| What it gives you | A number to display on the listing | The right to rent |
| Where | Online, tourist tax website | Nice Côte d’Azur Metropolis |
| Timeline | 2 minutes | 4 months of processing, silence means refusal |
| In quota zone | Still issued | Filing open September 1 to December 31, 2026, within quota limit |
| Granted automatically | Yes | No |
The easy procedure isn’t the one that matters. That’s the whole problem.
What change of use is
It’s the authorization issued by Nice Côte d’Azur Metropolis to rent a secondary residence as a tourist furnished rental. Four characteristics, and each one surprises the owners I work with.
It is personal and non-transferable. Attached to the person, not to the property. It doesn’t transfer to another property and can’t be sold. Buying an apartment that was rented on Airbnb by its previous owner gives you no right to rent it in turn. It’s the most costly point, and the least known.
It’s free only once. One temporary authorization without compensation per tax household. From the second property onward, compensation applies, which breaks the equation for anyone wanting to build a small portfolio.
It’s temporary. Five years, non-renewable and non-divisible. Beyond five years, you must go through compensation, meaning putting another property back on the housing market, or through the mixed rental scheme described below.
It’s not guaranteed. In quota zones, authorizations are limited in number and applications are ranked.
What you need to do, in order
1. Verify the address before anything else. Before buying, before calculating yield, even before visiting if the project is purely rental. We’ve put online a free tool to find out if a Nice address is in a quota-restricted zone: you enter the address, you get the answer right away.
2. Determine the property’s status. A primary residence can be rented without change of use, limited to 120 days per year. A secondary residence requires authorization.
3. Request authorization if required. The processing period is four months, and administrative silence means refusal. In quota zones, applications are made only through online services, during an annual window: for 2026, September 1 to December 31. One application per owner per campaign; any additional application is rejected.
4. Only then request the registration number. Two minutes. Final step, not the first.
5. Display the number on each listing and declare the tourist tax.
The reversal of steps 3 and 4 explains nearly all irregular situations I encounter. Owners aren’t trying to circumvent the rules; they stop at the step that seemed to be the end of the process.
Where it gets stuck: quota zones
Nice has defined four zones—Old Town, Riquier-Port-Mont-Boron, downtown, and West—covering 39 IRIS areas. The 2026 quota is set at 0.9% of residential units, which gives a maximum of 691 authorizations for the year. In neighborhoods where short-term rental makes the most economic sense, the number of available slots is finite.
Applications, suspended for part of the year, reopened September 1, 2026 and remain possible until December 31. The regulations are clear on the selection method: requests are processed in order of arrival, time-stamped by the platform, provided they are complete. An incomplete application isn’t held pending documents; it’s rejected, and rejected applications don’t join any waiting list. Filing early and filing completely are therefore two equally weighted conditions. The Metropolis also announces a recalculation of quotas by end of 2026, for new regulations applicable in January 2027.
An owner contacted me this year. He had just bought in Nice and done his calculations: purchase price, monthly payment, expenses, expected income, yield. The file made sense. He was calling to organize the rental launch. I told him that day that his property was in a quota zone and that applications were then suspended. His project no longer worked.
He hadn’t miscalculated. He’d calculated on an assumption that no longer existed, and nothing in his purchase process had flagged this for him. The rule is public; it’s legal. It simply doesn’t reach the people it concerns at the moment when it would be useful to them—that is, before signing.
What to do when authorization isn’t accessible
Let’s start with what not to do: rent as a tourist furnished rental without authorization. It’s not a formality you regularize afterward. The exposure is real, the platform keeps a record of stays, and the owner ends up having to stop overnight an activity their financing was based on. The detour is never worth the risk.
Three arrangements remain open, and they’re not equally valid depending on the situation.
Primary residence. It can be rented short-term up to 120 days per year without change of use. This is the simplest case, and the only one that allows tourist furnished rental without any procedure.
Mixed rental, students then tourists. This is the least known and most interesting route, because it falls outside the quota. An owner who rents to a student receiving CAF benefits for five to six months, at a capped rent, obtains a derogatory authorization to rent as a tourist furnished rental for three months in summer, June to August or July to September. These requests aren’t counted in the 691, and the scheme opens from the first request, including for an owner holding multiple properties or whose five-year authorization has expired.
The conditions are precise. Monthly rents excluding charges are capped at 525 euros for a studio, 680 euros for a one-bedroom, 890 euros for a two-bedroom, and 1,260 euros for three-plus bedrooms. Minimum student occupancy is six months for a lease signed in September, five months for one signed in October. A four-party agreement between owner, student, CROUS, and local authority must be signed by December 31, the change of use request filed by January 31 following, and the authorization issued between April 1 and May 31. The authorization is annual and renews as long as the scheme exists.
The timeline is the trap: everything depends on signing the agreement before the end of the calendar year, when the student is moving in, not in spring when you start thinking about the season.
Mobility lease. One to ten months, non-renewable, reserved for a tenant in a mobility situation: studies, internship, training, professional assignment. It allows renting month by month, keeping the property furnished, and gaining flexibility without falling under the tourist rental regime.
These regimes combine. On a primary residence, many owners use the 120 days during peak season then switch to a mobility lease for the rest of the year. You manage two regimes instead of one, with two sets of constraints and two tax systems, but you remain compliant and the property works year-round. In practice, this is the most common compromise among those who don’t obtain authorization.
Some field numbers
| Studio for two people in Nice | Summer 2026 |
| Median gross income per month | 2,467 € |
| Range depending on location | 2,083 € to 3,210 € |
| Average price per night | approximately 100 € |
| Average occupancy rate | 87 % |
| Share of foreign travelers | 67 % of bookings, 70 % of nights |
Data collected from properties managed by Mystralia Conciergerie, June to August 2026.
The last figure weighs in the local debate. Two-thirds of my bookings come from abroad. Nice’s short-term rental market isn’t primarily a domestic market; it’s a tourist gateway, with spending that goes with it in shops and restaurants.
Where short-term rental doesn’t make sense
At Mystralia, we refuse certain assignments. Not on principle: short-term rental doesn’t make sense everywhere. Beyond Pasteur, too high in the hills, in the western part of the city, a property generates little per night and would work better in standard rental. We tell owners who contact us frankly, even if it means losing the deal.
The market is already doing part of the work. Pressure concentrates on the center and tourist neighborhoods, not the entire stock. This argues for geographically finer regulation rather than a single benchmark.
What this system produces, from the field
The principle of quotas isn’t really debated: a city where year-round housing is scarce has good reasons to protect its residential stock, and Nice is in that situation. Debates are more about the fine-tuning.
First friction point: the level. The City sees it as compatible with its housing objectives. Sector professionals, myself included, believe that too low a quota doesn’t redirect the market but pushes it toward the informal sector. No public figures allow us today to settle between these two readings.
Second point: stability. An authorization duration extended from three to five years, a primary residence cap modified twice in one year, a filing window moved from February to September: the framework has shifted considerably in a short time, for understandable reasons, national law having itself changed. The concrete effect is that a purchase financed over fifteen years is decided today on a rule with a horizon of just months.
Third point, less discussed: property maintenance. A property rented nightly is refurbished and maintained because guests who sleep there rate it. The question of what will finance renovation of these properties once switched to long-term rental deserves to be asked, without prejudging the answer.
What’s most lacking is upstream work: how many year-round properties does Nice need, how many new properties are released each year, how much new construction is planned? These figures would allow calibrating a quota rather than adjusting it year by year. I have an interest in this matter; my job depends on it, and that’s also why I prefer a defined framework to a power struggle.
Meanwhile, the real daily problem remains information. It circulates poorly, producing owners in violation who believe they’re compliant. They’re not trying to circumvent the law; they all ask the same question: what do I need to do to be able to rent?
