Businesses serving food and drink - such as pubs, bars, restaurants, cafes, coffee shops, snack bars, and ice cream parlours - are eligible to request temporary outdoor seating in suitable locations.
This follows a recent law change which means district councils can now issue these licences and waive the usual fees.
Councillor James MacCleary, Leader of the Council and Cabinet Member for Regeneration and Prosperity, said: "I want to ensure businesses are getting as much support as possible to help them through the many difficulties posed by Covid-19.
"By making these licences available to eligible businesses free of charge, we hope to give district businesses a much-needed boost to support their recovery plans."
Councillor Johnny Denis, Cabinet member for Communities and Cabinet, said: "The summer season is well and truly here, with people wanting to make the most of the sunshine, so I hope businesses take up on this offer to extend their service outdoors. Getting a licence is a quick process and completely free of charge."
Once issued, the licences last until September 30, 2021.
