Summary
Lehi requires an active ADU license for as long as an accessory dwelling unit is rented, and Section 26.030(H) forces a choice: a property may hold both an ADU permit and a Short-Term Rental permit, but only one of the two uses may be active at a time on the lot.
H. Both an Accessory Dwelling Unit and a ShortTerm Rental permit may be obtained; however, only one of these uses may be active at a time. Only one accessory dwelling unit shall be in service at any given time per single-family dwelling lot.
Full Breakdown
030 conditions ADU rental on an active license: as long as the unit is rented and in use, an active ADU license is required. That license runs with the ongoing rental use, not just the initial construction permit, so a lapsed or unrenewed license removes the unit from legal rental status even if it was built correctly. ' A homeowner can hold both permits on paper but cannot run an ADU tenancy and a licensed short-term rental in the same structure or on the same lot at once; switching from one to the other means deactivating the first.
The same subsection caps density at the lot level: only one accessory dwelling unit shall be in service at any given time per single-family dwelling lot, so a property cannot license an internal ADU and a detached ADU together even if both structures physically exist. Combined with the owner-occupancy affidavit required under subsection A, these rules confine Lehi's ADU rental market to owner-occupied lots running exactly one dwelling unit and one licensed use at a time.
Violations & Fines
Renting an ADU without a current ADU license, or running an ADU tenancy alongside an active Short-Term Rental permit on the same lot, violates Section 26.030(H) and can be enforced under Chapter 34 through citation, fines, and suspension of the rental use until the property is brought back to a single active licensed use.
