As a landlord I care about abuse of my property and other people complaining. If that is not happening - who cares.
Examples of things your landlord may care about even without a “no lasers allowed” clause. Drilling a hole through the wall to vent it? Yeah, I care about that. Snaking a hose out through a window in a Wisconsin winter when daytime highs are below zero Fahrenheit, that can cause issues. Open window in the summer and suddenly there is a fly infestation? Or a curious squirrel (that actually happened.) Cutting leather and having burnt hide fumes permeate the building so all the other residents complain. Basically it comes down to common sense. Also, as I posted here, it’s a good idea to have renter’s insurance.
