Almost two thirds of students in UCD are paying more than 750 euro a month in rent.
That's nearly twice the national student average.
The survey by UCD's Student Union asked more than 1,500 students about their living arrangements while in college.
45 per cent of those surveyed said they found it 'very difficult' to find accommodation while 26 per cent said it was 'somewhat difficult'.
The average rent a month for a UCD student stands at 750 euro - compared to 469 nationally.
The survey also found more students are now looking at 'digs' as an option.
The students union says the States failure to respond to the housing crisis is having an impact on students mental health, education and overall college experience.
