re: Airbnb Host, anyone know what the city of New Orleans defines a bedroom as?

Very few condos allow you to sublease and they can absolutely enforce it. Almost all hoa's have an exclusion that will allow them to remove you if you sublease. The only situation you will find someone subleasing is if you know someone who owns property and they will allow you. As part of the permit they review the owner of the building. If you don't own they require a letter from the owner authorizing you to get a license.
