is it cumpulsory for IIT Madras undergraduates to stay in hostel?

The  IIT (Indian Institute of Technology) Council meeting with the Minister of Human Resource Development (MHRD) on August 23, 2016 led to many developments. One of these decisions was to allow students to stay off-campus to increase the intake of candidates across of all courses in the next four years. IITs are planning to increase their total number of students by about 30,000 till 2020, which will increase the total number of students from the current 72,000 to 1 lakh. 

You can say it is mandatory from money point of view. The Institute will not exempt you from mess and hostel fees fully
