Continuous balconies, carved carriage doors, polished staircases: the 9th arrondissement is Haussmann-building country. Between boulevard Haussmann, rue de Châteaudun, place Saint-Georges and rue des Martyrs, many owners wonder one day whether they can offer their flat to visitors. The answer depends neither on the floor area nor on the view. It depends first on one status: is this flat your main home or not?
We have read the City of Paris texts to give you the broad outline. This article is not legal advice; it helps you see which box you are in before going any further.
Two regimes, one dividing line
The City of Paris does not treat in the same way an owner who rents out their own home while away and one who devotes a flat to hosting visitors. In the first case, short-term renting remains an occasional use of a lived-in home. In the second, it amounts to taking a home off the housing market, which the City regulates strictly.
Three situations come up often in the 9th:
- you live in your flat near rue des Martyrs and travel regularly for work;
- you inherited a one-bedroom flat near place Saint-Georges that nobody lives in;
- you keep a pied-à-terre in the Opéra district that you use only a few weeks a year.
The first falls under the main-home regime. The other two fall under the second-home regime.
If the flat is your main home
This is the most open case. Two rules apply.
Declare the flat and display its number
Every furnished tourist rental in Paris must be declared to the City, which assigns a registration number. That number has to appear on each published listing, whatever the platform. We always add it when distributing your listing.
Stay within the permitted number of days
Since 1 January 2025, a main home can only be let as furnished tourist accommodation for 90 days a year in Paris. The cap used to be 120 days; the City lowered it using the law of 19 November 2024, which gives tourist municipalities that option. The City of Paris explains this in its online article devoted to the 90-day cap, on paris.fr.
For a 9th-arrondissement resident who is often away, this leaves real room, provided the calendar is organised: identify the weeks you will be absent, open bookings for those periods only and add up the nights sold across all platforms. When you entrust your flat to us, that total is part of what we follow with you.
If the flat is a second home
The framework becomes much more demanding. Welcoming visitors in a property you do not live in requires a change-of-use authorisation, granted in return for compensation. Compensating means providing other premises that become homes, to replace the one being converted.
Where to compensate: the administrative quarter
For furnished tourist accommodation, the municipal regulation requires the compensation to be located in the same administrative quarter as the flat concerned (article 3). The 9th is split into four administrative quarters, including Saint-Georges, Chaussée-d’Antin and Rochechouart. An address near Chaussée-d’Antin therefore cannot be offset by premises located in another of these quarters, even a few streets away.
How much to compensate: the triple rule
The 9th is included in Annex 6, a map that marks out the “3 for 1” compensation zone. There, the premises provided must cover three times the floor area of the converted flat. According to the consolidated regulation, the map covers the 1st to 11th arrondissements and the 18th: the whole of the 9th is inside it.
Which premises are accepted
Article 2 of the regulation sets the conditions: compensated premises must become new homes, meeting decent-housing standards, and must never have been used for another compensation. Enlarging an existing home does not count.
Reference text: City of Paris deliberation 2025 DLH 44, which carries the change-of-use regulation (consolidated on 3 March 2025; articles 2 and 3, Annex 6) (read the PDF).
In practice, for a flat in the 9th
An owner of a second home who does not already hold a change-of-use authorisation therefore faces a tough condition: gathering, within their own administrative quarter, three times the floor area of their flat in premises to be turned into homes. Few private owners can. It is better to take this into account from the start than to prepare a listing that cannot be published. Other rental formulas exist; we look at them with you case by case.
An owner who lives in their flat, on the other hand, can rent it out while away within the annual cap. In the 9th, where business travellers in the Opéra district mix with visitors who come for the department stores and theatres, choosing your weeks well makes all the difference. Our short-term rental calendar for the 9th helps you spot the strong periods.
Life in the building matters too
A Haussmann building is a community: a caretaker, next-door neighbours, shared common areas. The co-ownership rules organise that shared life, and your managing agent can send them to you; reread them before you start. Day to day, a well-run rental goes unnoticed: arrivals explained in advance, building rules passed on to guests, cleaning after every checkout and bins put out according to house rules.
What Laura and Hannah do from the first conversation
Before talking about prices, Laura and Hannah ask whether the flat is your main home and whether it already holds a change-of-use authorisation. Those two answers are enough to know what is possible. If renting is an option, these rules are part of every step of how we support owners.
Caution: consult paris.fr before you commit
The rules described here rest on municipal deliberations and on the law, which can be amended. The Annex 6 perimeter is drawn on a map, not set address by address. Before buying, signing or publishing a listing, read the applicable texts on paris.fr, then ask the City’s housing department (DLH) to confirm your case.
Frequently asked questions
Can I rent out my main home in the 9th on a short-term basis?
Yes, once it has been declared to the City of Paris to obtain a registration number, and within the 90-day annual limit in force since 1 January 2025. Check the current rules on paris.fr.
What do I need to rent out a second home in the 9th short-term?
You must obtain a change of use, granted in return for compensation. In the 9th, the compensated premises must cover three times the floor area and be located in the same administrative quarter (City of Paris deliberation 2025 DLH 44).
Can enlarging another home count as compensation?
No. Under article 2 of the municipal regulation, compensated premises must create new decent homes and cannot be an extension of an existing one.
Where can I check the rules before I start?
On paris.fr, then with the City’s housing department (DLH), which can confirm your case.
