A one-time, large-scale event is an event (with over 500 participants) aimed at "bringing pleasure to the public", which is held in an open or closed space which is not licensed for such an event by a valid business license (for example, events held in parks, on a promenade, on city streets, in city squares or in other halls and enclosed places not intended for such activities).
A one-time event requires a business license, but the procedure for receiving the license is different from the usual process, as preparations for the event need to be carried out in a short time and with obvious limitations. The application for a large-scale event must be submitted up to 30 days before the date of the event. Licenses for "mega" events (with over 10,000 participants) must be submitted up to 45 days before the date of the event. For a one-time event where food is served, an additional item 7.7G (food fair) will be opened.
