    New construction on land inside Fairfield township, which is unincorporated Bureau County and not one of the county's municipalities with its own zoning ordinance

    • The county FAQ lists decks, sheds of 144 sq. ft. or more, garages, gazebos, dwellings, commercial and industrial buildings, and additions as projects that need a permit.
    • A structure needs a building permit whether or not it sits on a permanent foundation (county FAQ, skids question).
