We are specializing in Accessory Dwelling Units (ADUs).

Refrigerators accessories and garbage disposals are my biggest reoccurring issues.

So an ADU (accessory dwelling unit) will allow you to make the property into two units but the owner must live in one of the units.

Is it an accessory dwelling with another property on the land?

Labor, that's about a day or two work for demo, another day to form, and another to pour. 4 days average, 5 max, 3 guys, that's 5k, 2k on dumpster, 2.5-3k on concrete & accessories.

For finishing my basement and making it a legal accessory apartment here in Lehi, it wasn't too difficult a process to go through.

If the lot is big enough with the rental you already own, you can add an "accessory dwelling unit" and a "junior accessory dwelling unit" on the property you already own, you can convert a garage, etc. 

Exemptions include "Housing accommodations in which the tenant shares bathroom or kitchen facilities with the owner who maintains their principal residence at the residential real property.(5) Single-family owner-occupied residences, including a residence in which the owner-occupant rents or leases no more than two units or bedrooms, including, but not limited to, an accessory dwelling unit or a junior accessory dwelling unit."

If you had some type of accessory building, then sure, but not in the house.

I added a clause about Vaping to the Addendum.
