Roommates. They're a fact of life for many young people who wantto live in the heart of major cities across the country, with whatrents are nowadays. But what many don't know is that they may bebreaking the law.As explained in a recent article in the New York Times, severalareas, including-surprisingly-New York City, have laws againstallowing more than three unrelated people sharing a residence.Though these laws aren't strictly enforced-or rather, are rarelyenforced-it may still be a concern for landlords.Saythese laws are enforced.
