Adding ADU to new construction home

[Connor See]

My wife and I are planning to build a new single family home in Eagle Mountain Utah and are trying to decide what to do about adding an ADU. We currently live in a townhome that's we will keep and rent out once we move, and are just trying to capitalize on appreciation in the area as much as we can with our limited funds. The thought is to add an ADU by putting a basement apartment that would be 2 bed 1 bath, with the main dwelling being 4 bed 2.5 bath. We recently found out about laws behind owner occupancy for having a legal ADU, in that once we move out, we could no longer rent out the basement as a separate unit. Just want to get some ideas as to what the best long term plan for the property would be. Total expense of the propert with the ADU would be about 2200 a month, with the ability to rent out the apartment for something like 1000 to 1100 a month, compared to about 1900 a month without the ADU. Do we plan to just sell the place in the future, is it best to rent out the home as one unit, or what other good viable options do we have/what do people recommend?
