Ordinance 2024-01, adopted February 7, 2024, allows internal and external ADUs in South Salt Lake's R1 and RM districts, under conditions that include these, in its own order.

• A single-family dwelling as the primary dwelling on the property
• No more than one internal ADU and one external ADU on a lot or parcel
• No short-term rental of the house or the ADU
• A predevelopment application, evidence of owner occupancy, a building permit application, a rental business license application, and any other land use application that applies
• No ADU within a mobile home, portable container, trailer, carport, canopy structure, or similar structure
• No sublease of any part of the ADU by its occupants
• The owner occupying the house or the ADU, except on a property whose principal use is a multifamily dwelling, or while the owner is on active military service or placed in a hospital, nursing home, assisted living facility, or similar facility that provides regular medical care, other than a retirement living facility or community
• An internal ADU on a lot of at least 6,000 square feet that is at least 50 feet wide at all points from the front property line to the rear, with the unit located within the primary dwelling
• One on-site parking stall for an internal ADU beyond the home's requirement, with no fewer than three off-street stalls in total and no added stall where the home already provides more than four
• An exterior entrance under weather protection for an internal ADU
• An external ADU on a lot of the same minimum area and width, no taller than the house or 20 feet, whichever is more restrictive, and no more than two stories
• An external ADU of no more than 50 percent of the house's total square footage, not counting the garage, or 1,000 square feet, whichever is more restrictive, covering no more than half the rear yard
• An external ADU at least 10 feet from the house and 5 feet from the side and rear lot lines, with one added on-site parking stall, no more than two bedrooms, and a location outside the front and corner side yards
• Conversion of an existing accessory structure only where it meets the ADU setbacks for the district and the building codes

The city's ADU page also states that a second utility meter cannot be added for the ADU and that the Planning and Zoning Division must receive and process the ADU Predevelopment Application before a building permit may be processed. Utah's ADU statutes apply in South Salt Lake as well, as our ADU page explains.
