Separate Hot Water tanks for SFH

[Conte Cuttino]

I'm renovating a SFH with an apartment included sharing one water service. Should I install two electric hot water tanks for each unit even though it's one water service that I'll be paying for? I'm mainly doing this to separate the Electic usage for the hot water tanks but do you guys think it's necessary since it's not an Offical duplex.

 You are thinking of your choice from a financial / landlord perspective, when I would suggest you think about it from a functional / tenant perspective. 
Pretend you will be living in one side of your duplex… it’s 8am and you go to take a shower, but there’s only 1 minute of hot water left because your next door neighbors took showers at 7:30 and 7:45am.  Ponder that and you will find your answer pretty quickly.

It’s not about whether it’s an official duplex, it’s about functionality… especially if you may have 4 people living on each side.  Each side should be entitled to their own hot water supply, regardless of who is paying the water bill.  And think of this… whose electric bill would a single water heater go on?  
All the best!
