Schedule E property type

I own a single family home that has been split into two units - an upstairs unit and a downstairs unit. Both units are complete dwellings, and they have separate entrances. But, we share a single address (the city considers the property to be a single family home) and all utilities. I live in the upstairs unit and rent out the downstairs unit.

 

I am trying to determine how to answer the basic question of whether this is a single family or multi family home for Schedule E. I have found previous threads on this exact question but with conflicting responses. Can anyone confidently tell me which it is?
