An administrative law judge has ruled that a New Yorker who rented his apartment on a popular traveler site broke the law. East Village condo tenant Nick Warren was ordered to pay a $2,400 penalty for subletting his two-bedroom apartment to a Russian tourist in December on Airbnb.com.

Clive Morrick of New York City’s Environmental Control Board ruled on May 10 that Warren broke the law because he rented his apartment for fewer than 30 days and wasn’t home while the tourist occupied it. Rental agreements are legal under state law only if the "host" remains home during the rental period.
