Older house - include surge protection for electronics in lease??

[Anna Watkins]

So I have this older house, bought as a student rental for my own son and his buddy/roommates, all of whom have lots of electronic devices (computers, laptops, xBoxes, projectors, phone chargers, etc etc).  Hardly any of the outlets are grounded, and there's no "whole house" surge protection.  I have renter's insurance awareness in my lease, and am thinking of putting in an additional clause that each roommate should bring his own surge protection power strip as additional insurance for the electronics.  Have you included any kind of "awareness" clause in your leases for this kind of situation?
