    Tips

    • IADUs are restricted to the Residential R-1 Zone and to long-term rental (30+ consecutive days) — short-term/nightly rental of an IADU is not permitted under Kanab's ordinance.
    • An IADU does not get its own separate utility meter/connection; the property owner is billed for two city utility connections on a shared line.
