Pets are prohibited in any undergraduate or graduate residence hall. The term “pet” includes mammals, birds, reptiles, and amphibians. Residents are permitted to keep fish in tanks no larger than 20 gallons.

Students in the following residence halls may be eligible to participate in a program that allows a very limited number of cats to be kept in certain residences.

  • East Campus
  • Random Hall

In limited circumstances, the Disability and Access Services Office may approve a resident’s use of an assistance animal (often for emotional support reasons) as a reasonable accommodation for the resident’s use in the resident’s dwelling unit, or acknowledge a dog as a “service animal” which has been individually trained to do work or perform a task on behalf of an individual (not necessarily a resident) with a disability.  Any individual approved for such assistance animal is responsible for ensuring that the animal does not unreasonably interfere with routine activities or cause unreasonable difficulties for residents of the building or other MIT community members.
