They would not be able to just go into your apartment unannounced for that. They would need to notify you in writing that they were going to do that and at least give you the opportunity to be present when it is done. At the same token, I am never surprised at what some co-ops do. Being that a co-op is not real property, they do not have to abide by the laws pertaining to actual real estate. Based on this they can get away with murder (well not actually murder but close to it).
