ADU rules in Sandy, UT — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Sandy permits both internal and detached ADUs in single-family zones under Utah Code §10-9a-530 (HB 462/SB 174). Internal ADUs are permitted by right with registration; detached ADUs require a conditional use permit. Owner-occupancy cannot be required by state law.
Sandy adopted ADU ordinances consistent with Utah HB 462 (2022) and SB 174 (2023) preemption. Internal/attached ADUs (within the primary home or attached) are allowed by right in R-1 zones with a registration and safety inspection. Detached ADUs (separate backyard structures) require a conditional use permit and must meet setbacks: typically 5 feet from side/rear lot lines, max 75% of primary dwelling footprint or 1,000 sqft (whichever less), and maximum 25 feet height in most zones. Sandy cannot require owner-occupancy of either unit or additional off-street parking beyond the primary home requirement under state preemption. STR use of ADUs is separately regulated — Sandy requires an STR license even if the ADU is otherwise compliant.
Unpermitted ADU construction: stop-work order, retroactive permitting, possible removal. Unregistered internal ADU: $250-$1,000 civil penalty. STR operation without license: $500-$2,500/night.
