On July 27, 2026, Paris Mayor Emmanuel Grégoire convened the main co-owners of the Montparnasse Tower to mediate a long-standing dispute over the building's renovation, which has been stalled since 2015. The project, now estimated at 800 million euros, faces tight deadlines as the building permit expires at the end of November 2026. Co-owners recently approved asbestos removal preparations but made the start of work conditional on resolving internal disagreements, primarily over floors designated for a hotel and surface exchanges. Mayor Grégoire positioned himself as a guarantor of Parisian interests while acknowledging the project is private. A second meeting is planned for after summer, with the mayor urging co-owners to work collaboratively. The renovation envisions transforming the tower into a glass structure with terraces, a hotel, shops, and a rooftop greenhouse.

The main co-owners of the Montparnasse Tower were brought together on Monday, July 27, by the Mayor of Paris, Emmanuel Grégoire, to discuss the renovation of the building, which is threatened by an internal conflict. According to his entourage, the meeting allowed participants to "lay the groundwork" before a new appointment.
Last week, the co-owners of the tallest skyscraper in Paris approved the preparation of asbestos removal work but made the start of this first phase of renovation conditional on the resolution of internal disagreements opposing certain parties.
Key Issues
The main challenge is reaching an agreement regarding the floors intended for the creation of a hotel. These floors are owned by several co-owners who disagree on:
- Joint operation
- Surface exchanges
Additional conditions include surface exchanges on other floors and the withdrawal of legal appeals.
Mayor Emmanuel Grégoire "listened" and "understood a number of problems," reported Frédéric Lemos, one of the co-owners present at the meeting.
Tight Deadlines
"The meeting allowed us to lay the groundwork," and a second meeting will be scheduled, the entourage of the socialist mayor told Agence France-Presse, noting "a shared desire to work serenely and away from media pressure."
"The Mayor of Paris expressed the wish that we meet again at the end of the summer and that, in the meantime, the co-owners should work together in good collective intelligence," continued Frédéric Lemos, former president of the tower's syndicate council.
The building permit expires at the end of November, meaning work must begin before that date. Otherwise, the entire project would have to be revised before submitting a new permit application.
Emmanuel Grégoire "is aware that this is a private project," in which he can hardly influence internal negotiations, and "has positioned himself as a guarantor of the interests of Parisians, given that this project is highly visible," added Mr. Lemos.
Project Background
Under discussion since 2015, the vast renovation plan envisions a metamorphosis into a glass tower with tree-lined terraces, housing:
- A hotel
- Shops and services
- A greenhouse on its roof
The overall cost has skyrocketed from the initially announced €300 million in 2017 to €800 million, according to the most recent estimate.
