How are inspections scheduled?

Reinspection after a corrective-action order is charged at the current fee-schedule rate.
Which codes and exemptions should I review?
Trempealeau County is the state-delegated permitting and inspection authority for new and altered one- and two-family dwellings under the Wisconsin Uniform Dwelling Code, Wis. Admin. Code SPS 320-325, and for camping units under SPS 327. County Land Management also administers the Trempealeau County Comprehensive Zoning Ordinance, sanitary/POWTS, shoreland, floodplain, erosion-control and related land-use requirements. State plan approval applies to public and other state-regulated commercial buildings when required. The county fee schedule states that building permits are not required for re-siding, re-roofing, finishing interior surfaces, installing cabinetry, and other repairs or restorations that the building inspector determines are not required to meet the current code. Generators, spas, hot tubs and pools may still require land-use/zoning and mechanical permits and inspections; local municipal acknowledgement is required for county permit applications.
