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.
