WE have always gone by a general rule here, if it increase the value of the investment it is the landlords responsibility.. If it is general repairs of existing things than it is rentors responsibility.. For example, when we had to rebuild facilities because they were completly shot we talked to the landlord and he is the one who offered up the money for replacing them because he wanted the area looking nice and clean and whatever.. Of course, the accountant for the bossman also basically told us if it isn't moveable the land lord will pay for it (Some tax reason that is beyong me knowledge, lol).
