The 31-year-old says she wouldn't be too bad to live with because she doesn't make a lot of mess.
In an interview with British Stylist magazine, which can be read online at www.stylist.co.uk, the 500 Days of Summer star said: 'I think I'm a fun flatmate. I'm always cheerful. I go on tour with my band so it's 12 people on one bus and I feel like I'm the one who's happy in the morning. I'm not a chaotic person, but I might slack off on doing the dishes from time to time.'
But Deschanel admits she would rarely be in at the moment because she is so busy producing and starring in her new TV show New Girl.
She added: 'This show is my life. And most of my free time is preparing for the show and working on next week's script, thinking about what we're doing in the future, making sure that everything feels right, memorising lines and working on my character. I haven't been to the grocery store in months!
'But it's been wonderful. I love getting to help shape the show and be a part of the decisions that are made on set.'
