Our landlord is quite laid back, but there are somethings which they expect of us.
Note that the sign on the door states “KEEP DOOR CLEAR AT ALL TIMES.”
If people persist in leaving materials here there is an excellent chance that they could be thrown out.
Other members report finding scrap/salvaged wood with upholstery on it in this area. That is an excellent way to spread bedbugs in the space. It has been thrown out. DO NOT DO THIS.
