What applies in Provo

Utah requires municipalities to allow internal (within the home) ADUs by right in most single-family zones, with limited local restrictions.

Because Utah has a statewide ADU law (Utah Code §10-9a-530), Provo must follow these minimums even where its older zoning code is stricter. Confirm fees and design standards with the Provo planning department.
