You plan to sub-meter the water in a MIL apartment?
Water must be very expensive out there.
Split or Tee as needed to isolate the pipes service the MIL area from the rest of the house... but do that in a spot it will later be practical to get to.
If/when you ever install a meter... deal with that days plumbing project then.
