How are inspections scheduled?
Call CPZ at 715-261-6000 to schedule an appointment or coordinate zoning, shoreland, floodplain or POWTS inspection; applications may also be emailed to cpz@marathoncounty.gov. Building/UDC inspections are arranged separately with the building-code official responsible for the property's town, village or city.
Which codes and exemptions should I review?
Marathon County General Code Chapters 15 (private sewage), 17 (general zoning), 21 (nonmetallic mining), 22 (shoreland) and 27 (floodplain), plus airport and related Wisconsin regulatory standards. These programs apply countywide except that comprehensive zoning is effective only in participating towns. CPZ does not administer Uniform Dwelling Code building permits; contact the building-code official for the specific municipality. Accessory structures or additions smaller than 100 square feet are exempt from the general county zoning permit fee/permit threshold. Temporary storage or shipping containers used solely for supplies, waste or equipment during an active construction, grading or agricultural project may be placed without a zoning permit for no more than 90 days or until the related project permit expires. All town, county and state municipal projects are fee-exempt under the county schedule.
