Ogden runs a deliberately owner-occupied model: one ADU per single-family lot, the owner in one unit, and a cap of two adults in the other. Its 300–800 sq ft detached range is tighter than most Wasatch Front cities and rules out the larger Arena plans.
“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.
