Rent for a Paris pop-up varies by street, by duration and by season, so a single average describes nothing. The range across our own Paris retail listings, what moves a space up or down inside it, and the costs that are not rent.

Paris does not trade by arrondissement, it trades by street. What each of the main retail areas is actually good for, how the city grades its own streets, and five checks worth doing on a specific address.

Paris regulates retail at street level, not city level, so the same activation can be simple on one road and complicated two streets away. What the French and Paris authorities actually publish on short-term leases, pavement permits, retail protection, safety and access, and Sunday trading, with the six questions worth taking to a landlord.

The parts of running a pop-up that are different in Paris: employing staff without a French entity, what language the floor works in, tax-inclusive price labels, and why Sunday is settled address by address.

Which permits and licenses a New York pop-up shop actually needs, which agency issues each one, how long they take, and when they do not apply to you at all.

What a New York landlord will ask for before handing over keys, what the state requires once you put staff on a shift, and the order to sort it in.
