Rents in the city are up by 8 percent on last year.
The soaring costs, which average at more than 600 euro to rent a double bedroom, comes at a time when thousands of students are looking to move to Dublin before starting college.
Daft.ie says 2 thousand 2 hundred fewer properties were available for tenants on the first of August, compared to the same time last year.
Renting a single bedroom in the city centre where large colleges such as Trinity, DIT, Griffith College and NCAD are located, averages at 507 euro each month - a 10 percent rise on 2014.
Student representatives are calling for the government to act, amid fears that college-goers will be priced out of the market.
