I have two TV’s in my garage, I turn them on but very seldom watch them, just some back ground noise to keep me company.
When we have party’s The garage is the place where all the car people go to any very seldom go to the house unless to use the bathroom.
I have my garage wired separately from the house so we can set the alarm to the garage with out setting the house also vice versa, also it is set up so it he garage alarm goes off it will set the alarm off in the house and that alarm will call the alarm company.
Another feature is to have a heat...
I am sorry your neighbors have too much time on hand on there hand so they have to mind other peoples business. If you were only 3/8” to high could you have removed the sheathing and replaced with metal then you would still be in code?
