Separating utilities on a SFH

[Account Closed]

I have a SFH that I am planning on renting out to two separate tenants. The upstairs and downstairs of the house are completely separate with separate entrances. However, since it is a SFH all of the utilities are currently combined. I am planning on renovating the downstairs but am wondering if I can split the utilities if the neighborhood is not zoned for multi family? Or would you suggest to have the utilities be included as a part of the rent and just charge a flat monthly fee that includes rent and utilities.? TIA.
