Sandy has permitted accessory apartments for years, but through a discretionary approval tied to a business licence. S.B. 284 bars a conditional use permit for a qualifying detached unit in a residential zone, so Sandy's process is one of the ones most likely to change before October 1.
“A specified municipality shall adopt a land use regulation that permits a detached accessory dwelling unit on any lot or parcel that is 11,000 square feet or larger…” — S.B. 284, Enrolled Copy, Utah Code § 10-21-304, effective October 1, 2026.
