ADU rules in Davis County, UT — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Utah law makes an internal accessory dwelling unit a permitted use in residential zones. Layton, Bountiful, and other Davis County cities must allow one internal ADU inside an owner-occupied single-family home; detached ADUs stay under local zoning.
Under Utah Code 10-9a-530, an internal accessory dwelling unit (created within the primary home's footprint for 30-day-plus rentals) is a permitted use in residentially zoned areas, and cities may not ban them. A municipality may require one additional on-site parking space and may prohibit renting the ADU if the home is not the owner's primary residence. Detached ADUs and units on unincorporated Davis County land follow Davis County or city zoning. Confirm specifics with your city (Layton Planning 801-336-3780) or Davis County Planning.
Renting a non-permitted or non-owner-occupied ADU can trigger zoning enforcement, fines, and property liens under the statute's remedies.
