A high-powered group set up to ensure the city keeps moving during the sporting event has decided that the Games organising committee will have to approve new or changed outdoor areas in the city centre or near venues.
Businesses which held the licence necessary to operate an outdoor area before October 11 last year will be exempt, provided they do not make changes.
Every other operator will have to apply to Glasgow 2014 for permission.
The new rule is part of Get Ready Glasgow which pulls together the work being carried out to keep the city functioning in the run up to and during the Games.
The move is supported by the city council, Glasgow 2014, Police Scotland, Glasgow Chamber of Commerce and Transport Scotland.
They are drawing up plans for community events to keep residents and businesses informed about how the Games will impact on them.
Later this month, campaign bosses will be writing to more than 300,000 homes and businesses telling them of the meetings.
Council leader Gordon Matheson said: "We want to keep the city running as close to normal as possible and we want to make sure people can also enjoy the Games and feel proud of their city."
Get Ready Glasgow bosses say transport networks will be busy coping with the increased demand and roads and public transport will be busier than usual.
David Grevemberg, Glasgow 2014 chief executive, said: "The city will be bustling with activity and may operate differently to ensure we can deliver an outstanding event everyone can enjoy."
Individuals, businesses or organisations hoping to hold street parties, extend trading hours, run mobile vending units or hold a special event may require a licence. For details, visit www. getreadyglasgow.com
