Weber County, UT Accessory Structures: ADU Rental Restrictions (2026)

Section 108-19-3 of the Land Use Code addresses ADUs directly under the heading 'Short-term rentals not allowed,' pairing the owner-occupancy rule with an outright bar on nightly rentals. Neither the single-family dwelling nor the ADU built on the same lot may be used, or licensed, as a short-term rental, described elsewhere in the code as a 'nightly rental,' unless some other provision of the Land Use Code specifically authorizes it for that property. The rule closes off the common workaround of renting an ADU nightly on booking platforms while claiming the primary home is owner-occupied: both structures on the parcel are covered by the ban, not just the accessory unit.

The prohibition sits alongside the county's separate one-family cap on the non-owner-occupied unit, so even a longer-term rental of the ADU is restricted to a single family, not multiple unrelated tenants or rotating short stays. Because ADUs require a land use permit under Section 108-19-5, and a business license if the unit is rented at all, the county has two separate checkpoints, permitting and licensing, at which a short-term rental use can be caught and denied. The rule applies only to the unincorporated county; incorporated cities in the county, including Ogden and Roy, regulate nightly rentals under their own municipal codes.
