Sandy, UT Accessory Structures: ADU Rental Restrictions (2026)

Sandy City Code Section 21-11-1 directly addresses short-term rental of accessory living space in single-family zones. It is prohibited to rent or offer the rental of an accessory apartment, extended living area, or guesthouse for a period of less than 30 consecutive days, closing off the nightly or weekly rental model for these units. That prohibition applies unless the property has separately obtained approval for short-term rental use under the City's Land Development Code and other Sandy City Code provisions, meaning a homeowner cannot simply advertise the accessory unit on a short-term platform without first securing that distinct approval.

The section goes further and prohibits mixing rental models on one property: in no event may any portion of the property be rented out for both short-term and long-term rentals at the same time. This sits alongside the section's broader occupancy controls, which limit an accessory apartment's occupants to a single additional family with no subleasing, and require that the extended living area be used only by the primary dwelling's family members, non-paying guests, or household staff on a non-rental basis. Because the accessory apartment permit itself expires upon sale of the property, a change of the primary occupant, or expiration of the accessory apartment business license, any short-term rental activity discovered after such a lapse would also place the unit outside its permitted use entirely, since the space reverts to extended-living-area status usable only by the primary occupants.
