The rental industry is booming and many people are looking for a way to make ends meet.
“I think it is a booming sector and there is a huge amount of demand for cars,” said Paul Mackey, director of the Dublin City Council’s transport department.
“I have had people come up to me in the street saying they are renting out their car and it is not too expensive.”
He said the number of people using car hire websites and mobile apps is up, but it is still low.
In the past year, car hire companies have increased their advertising budgets and the company offering the service, car rental firm RentACar, has been awarded €25 million ($30 million) in a development agreement with Dublin City.
The deal also sees the company set up a number of new offices in Dublin, which are expected to be up and running in 2021.
RentACar has about 1,500 cars in its fleet.
But Mr Mackey said a growing number of young people are moving to Dublin to work and the number is growing rapidly.
He expects the number to reach 20,000 vehicles a year by 2020.
