(The irate tenant does woodworking/crafting and uses strong chemicals daily).My office manager felt unsafe and suspected that the tenant was under the influence of drugs, so she called the police, closed the office for 1 hour, issued a lease violation, and immediately walked the other unit where the tub was being resurfaced.

They can, and do, control and police ridiculous things like what color you paint your front door, the condition of your window screens, the type and color of doorknob you install, where you store stuff, where you and your tenants park (I've had an HOA/COA tell my tenant she was not allowed to park her car on the property because her car was too ugly) - All of these are actual examples from my own experience - I am not making these up).5.
