How to rent single family home with efficiency?

I purchased my first investment a couple months ago. I found a single family home with a closed in car port that I have turned into an efficiency. Iv'e been thinking how I should rent out the property. Since there is only one water and one electric meter, should I include water and electric and set rent accordingly? I see in single family homes, people charge rent and the tenant pays for electric and maybe water. Just thinking about including electric, I feel like the tenant can just run up the bill like crazy. Looking for some ideas...Thanks for your help!
