Restaurants and bars across New York City with outdoor structures will soon have to pay to keep them.

The city had made the structures a permanent fixture after months of digging into the inspection process and how the Department of Transportation was policing outdoor dining.

The Department of Transportation announced during two public meetings that it is now working on new rules to regulate them including a charge to keep the outdoor spaces.

It's not clear how much the department will charge each restaurant or bar individually to register their outdoor space.

Businesses tell News 12 they can't handle another fee and that some have paid up to $20,000 per structure.

Other new rules include possibly making the structures semi-permanent or seasonal to make room for snow plows in winter.

The Department of Transportation has not disclosed how much it will be charging. The department has three more scheduled hearings - in the Bronx, Manhattan and Staten Island.
