Bars that have the opportunity to do so will be able to set up temporary terraces until October 31 in Paris.

They will have to make a request on the internet from June 21.

But the number of devices measuring potential noise pollution will be doubled, warned the mayor of Paris.

The ephemeral Parisian terraces will become summer, perpetuated each year from April 1 to October 31 and will always close at 10 p.m., announced Monday the mayor of Paris which exempts establishments from royalty until September 30.

At the end of dozens of hours of consultation, the town hall, representatives of the hotel and catering industry and residents' associations have agreed on the new rules for displays and terraces (RET) which will be presented at the beginning of July to the Council of Paris by Olivia Polski, trade assistant to the mayor PS Anne Hidalgo, and the first deputy Emmanuel Grégoire.

A competition for the most beautiful terrace

To perpetuate their summer terrace, establishments will have to apply for authorization online from June 21, while a simple declaration was sufficient since the end of the first confinement. They may continue to operate it pending final authorization, subject in particular to the approval of the mayors of the boroughs and whose renewal from year to year will be tacit. The ephemeral structures, which will therefore have to be dismantled on November 1, must remain open spaces, explains Olivia Polski to AFP: "roofs, tarpaulins, barnums, pallet wood, advertising will be prohibited", parasols and double-sloped canopies authorized and revegetation encouraged.

A competition for the most beautiful terrace will reward the best facilities.

These extensions can be installed on the parking spaces located in front of the facade of the establishment, plus a space on each side, the plots, median and, in the evening, on the space located in front of a closed neighboring business, if the latter agrees.

Electrical installations (heating, amplified music) remain prohibited and traders are held responsible for cleanliness, including under their decking and around within a radius of 5 m.

A "progressive sanctions scale" for noise pollution

On noise pollution, maintaining the closure at 10 p.m. - against 2 a.m. for classic terraces - is a "good compromise" with local residents' associations, Emmanuel Grégoire told AFP. The number of jellyfish, these sensors used to measure noise pollution, will be doubled, assures Olivia Polski. In the event of non-compliance with the new regulations, the town hall provides for a "progressive sanction scale" which will include fines of up to 500 euros, leading to a withdrawal of the authorization in the event of a repeat offense. "There will already be fines in the summer," warns Olivia Polski, even if the agents will be flexible during the transition period.

Exempt from terrace fees - classic or ephemeral - from the first confinement until September 30, establishments will then pay for terrace extensions a fee per m2 depending on the attractiveness of the street, a system already applied for terraces classics, according to Olivia Polski. Faced with a beginning of controversy over the end of these exemptions on June 30 for a sector hard hit by the crisis, Anne Hidalgo announced the extension of exemptions until the end of September.
