mini-dorm
n.— «Lee said a mini-dorm, which she defined as a number of students renting a house, is not considered a business and cannot be lumped in with boarding and rooming houses. The city can’t prevent groups of people, including students, from renting a home where they’re sharing common areas.» —“Mini-dorm restraint lauded by Sanders” by Sherry Saavedra Union-Tribune (San Diego, California) May 6, 2007.
