RUBS for Water & Gas

[Christopher LHeureux]

Good eve all - I am looking for info on how to implement a RUBS at a rental I have. It is a main house with an above garage apartment. The electricity is separate but gas and water are together. I have found lots of info about what RUBS is and many web-based companies - but nothing about how to implement a RUBS billing for a duplex situation. Has anyone used RUBS for a single duplex? Or is anyone in the same situation I am in - and found a way to bill utilities fairly to the tenants?
