The University of Peradeniya was originally planned as an entirely residential facility. Due to the increased intake of students in recent years, residential facilities could not be provided to all the students. However, a majority of students and a limited number of staff are provided residential facilities.
The University has 16 halls of residence for students and 4 Bhikku hostels. In addition, accommodation is available at the Agriculture sub-campus at Mahailluppallama (130 km north of Peradeniya) for first year agriculture students following the practical classes. Part time wardens from among the academic staff are appointed in charge of the organization and maintenance of discipline in the halls of residence. They are assisted by permanent wardens and part time academic sub-wardens. The halls of residence consist of study bedrooms which are shared by 2 or 3 students. An attempt is made to accommodate students of different faculties in the same halls of residence. A nominal fee is charged for the room and an additional fee per month is levied on students who use personal electrical appliances such as irons, radios etc. Meals are available in hall canteens where food is provided at prices fixed by the university.
