Charging utilities when I’m living in in law suite (ethical/legal)

[Josiah Horn]

My current home (SFH) I am splitting into a temporary "duplex" as the master has a private bath and separate entrance. I will be renting the remaining 3b1ba as an apartment until I save enough for my next property in approx 6months-1yr.

I would like to just rent it out as a standard apartment rent + utilities as to avoid wasteful practices with heat/electric. However as this is temporary can I just have them pay all of the utilities even though a heat vent goes to the in law suite and electric will be all on one meter.
