Eagle Mountain, UT Accessory Structures: ADU Rental Restrictions (2026)

EMMC 17.70.030(I) states plainly that short-term rental is prohibited: accessory dwelling units may not be rented for a period of less than 30 consecutive days. The rule applies to every ADU permitted under Chapter 17.70 EMMC, whether it is attached to the primary dwelling, built above a garage, or standing as a detached cottage home or casita, and it operates independent of the owner-occupancy requirement in EMMC 17.70.030(B); an owner who lives on the property still cannot rent the ADU nightly or weekly to visitors.

EMMC 17.70.040(C), which lists the ADU standards a public hearing before the planning commission can never waive, names short-term rentals specifically alongside the one-unit-per-lot cap, owner occupation, permanent utility connections, foundation requirements, building permits, exterior appearance, off-street parking, and addressing. That makes the 30-day minimum one of the few ADU standards with no exception path at all, in contrast to setback, frontage, or size deviations that the planning commission can approve case by case under EMMC 17.70.040(C)'s general exception process. An ADU advertised or booked for stays under 30 days is treated the same as an ADU built without a permit at all under EMMC 17.70.040: illegal until brought into compliance.
