    • Minor structures may be placed without a zoning permit but require zoning review; minor structures in Shoreland Overlay, Floodplain zones, and on nonconforming lots require zoning permits.
    • Applicants must submit the application and the fee established by County Board resolution to the Zoning Administrator; the affected Town Board receives a copy for notification.
    • If development conforms to the ordinance, the Zoning Administrator issues the permit; it is valid for two years from issuance.
    • If substantial work, defined as spending at least 30% of estimated value, is not completed, a new application and fee are required; the County Board may waive those requirements and extend for good cause shown, including natural disasters, acts of war, or temporary disability of a permit holder/laborer.
