Full Breakdown
Winnebago County Code Ch. 23 § 17.20 defines a residential garage to include a carport attached to the house or freestanding, and the county's zoning use matrix requires a zoning permit before building one in any base district. Section 23.8-460 sets the construction standard: a garage or carport must be conventional wood-frame, metal-frame, or masonry construction, and soft-sided structures and pop-up canopies are specifically prohibited. Placement then follows the accessory-building setback for the applicable district under Exhibit 8-2. This chapter only governs in a town whose board has adopted county zoning under Wis. Stat. § 59.69, and it never reaches inside Oshkosh, Neenah, or Menasha, which zone themselves.
Violations & Fines
Erecting a canopy-style or soft-sided carport, or starting construction without the required zoning permit, is a violation the zoning administrator can order corrected, removed, or brought into compliance.
