The Queens home where a third floor collapsed during a St. Patrick's Day party, seriously injuring one person, was issued five violations in 2004, the Department of Buildings said.
The agency said the violations ranged from not having the proper permits for construction to failure to fence off the work, according to The New York Post.
Neighbors said additions were made to the house in 2004 and 2005.
The DOB said about 100 teens were attending a party at the house Saturday night when the floor collapsed. It issued a full vacate order on Sunday.
Two people were hospitalized, one with serious injuries. Ten people refused medical attention. One person was trapped and had to be extracted.
The cause of the collapse is under investigation.
