Delhii Heights is a high-rise apartment in Delhi, where Abheer (Jimmy Sheirgill) and his wife (Neha Dhupia) live, a married couple who work for rival companies. It's about how their professional lives affect their personal ones. Also, there lives Timmy Kohli (Om Puri), a fun loving Sikh, with his wife Ruby (Kamini Khanna) and two daughters, Sweety (Sakshi Gulati) and (Shaina Ahluwalia). Then there is Bobby (Rohit Roy) and his wife Saima (Simone Singh). Bobby is a compulsive flirt and his wife knows about it. How things take place and how their lives change is to be seen.
Then there is Lucky (Vivek Shauq), a cricket bookie, a hilarious character in itself. Also, there are four boys (Mohit Sehgal, Anuj Sachdeva and Kinshuk Mahajan), residents of Delhii Heights, who keep running after girls and pulling each other's legs.
