Rules another office applies inside Gratz

Gratz does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Building permitLimited

    New single-family residences inside Gratz city limits

    • Building permits are not mandatory for single-family residences unless a local government passes an ordinance requiring inspections of single-family residences.
    • No Gratz city ordinance requiring permits for single-family dwellings was located; the city's own code was not found.
    • An Owen County Clerk page names a county building inspector for building permits; it does not state that the county issues permits inside Gratz city, so that link is unverified.
