As a part of our construction, we had several inspections and they signed off that we have complied with all laws required for single family residences  - the extra kitchen does not have an additional heating source (stove), all spaces are connected on the interior, and we have a single electric & water meter. 

Duplexes in my neighborhood are selling for $415-$435,000 and rent for $1,100-$1,200, including water/sewer (Bend does not allow 2 meters on 1 tax lot) Demand has been strong. 

$30,000 for water, but apparently Soquel water are being taken to court over this and maybe, just maybe they will not be allowed to charge that anymore for a 'separate' water meter!!! 

It is pretty common to have only one water meter on apartment buildings so the owner would have to pay for that.

All electric, separate meters. 

Go look at City Meter. 3.

Water/sewer isn't metered separately for each unit and the garbage fee is lumped in on the same invoice.

Do you know how much it cost to install a separate electricity meter on a duplex?

This is essentially just paint at 1k per unit. i would want more than that but your inspection would tell you all you needed to know-in a 16 unit, they would be (should be) on separate electric meters, which would be billed to the tenants, not you.

I've been looking into sub-metering a SFH home with a mother-in-law suite and experiencing difficulties regarding zoning and the utilities companies.
