hell yeah. theres nothing that anyone can say until you leave. and when you leave the rental, all you have to do is make it the same as when you moved in. if its just holes, then its easy to fix. i have holes galore in my bedrooms and storage closets alone with tapcons and steel plates on the concrete ceilings (apartment). they cant say shit as long as they dont know im growing dope. if they ever come in for an inspection they can ask why you have a hole, and you can reply with "its non of your fucking business, you nazi asshole. get the fuck out of my home". or something similar to get them off your case.
