A. 
General purpose zoning districts. For the purposes of this chapter, land uses, as defined in Article 3 of this chapter, are classified as principal, accessory, or temporary. Table 7-1 lists principal land uses (Series 1 to 16), accessory uses (Series 17), and temporary uses (Series 18).[1]
(1) 
Each of the land uses is designated as one of the following:
(a) 
Permitted in the zoning district by right provided that all other provisions of this chapter are met;
(b) 
Allowed in the zoning district as a conditional use provided that all other provisions of this chapter are met; or
(c) 
Not permitted in the zoning district.
(2) 
Any commercial or industrial land use that is shown as permitted that emits air contaminants, fugitive dust, or potentially offensive odors outside of the building; incinerates any substance; or handles radioactive materials, hazardous substances, hazardous waste, or regulated substances is considered a conditional use.

Editor's Note: Table 7-1 is included as an attachment to this chapter.
B. 
Planned development districts. Land uses that are permitted in a planned development district are enumerated in the general development plan for the district, along with development standards, if any.
Because the list of land uses cannot include every conceivable type of activity, those land uses that are listed in Table 7-1 shall be interpreted to include other land uses that are of a similar nature and have similar impacts to the listed use.
A land use that is not listed in Table 7-1 and which cannot be interpreted to be similar to any listed land use as provided for above is prohibited under authority of this chapter.
If a proposed project includes both an allowable land use and a prohibited land use, the prohibited portion of the project shall not occur in the zoning district.
A. 
Generally. Unless specifically permitted in this section or in other sections of this chapter, an accessory use as allowed in the zoning district shall only be established when a principal use is present or is being established on the same lot.
B. 
Exemption for a vacant lot adjoining another lot in same ownership. The Zoning Administrator may allow the establishment of an accessory use on a vacant lot provided the accessory use is allowed in the zoning district and such lot adjoins a lot in the same ownership that supports a principal use. If allowed, the property owner shall record an agreement and deed restriction with the Register of Deeds for Winnebago County that describes the authorized use and any conditions of approval. Such conditions of approval may relate to the use of the accessory use and the need to reestablish a principal use on the subject property within a specified time period.
C. 
Exemption for a utility cabinet. For the purpose of this chapter, a utility cabinet may be established on a vacant lot prior to the establishment of a principal use.
D. 
Exemption for storage building in A-2 District. In an A-2 zoning district, a storage building may be constructed prior to the establishment of a principal use provided the parcel is 5.0 acres or more. As a condition of approval, the property owner shall record an agreement and deed restriction, as approved by the Zoning Administrator, with the Register of Deeds for Winnebago County that describes the nature of the authorized use.
The Planning Commission may allow the removal of a principal building while retaining the accessory building when the Planning Commission determines that the principal building is dilapidated and the accessory building meets current building codes and serves a useful purpose. If allowed, the property owner shall record an agreement and deed restriction with the Register of Deeds for Winnebago County that controls the use of the accessory building and incorporates any requirement imposed by the Planning Commission as a condition of approval.
In addition to the standards in this article, community living arrangements must also comply with § 62.23(7)(i), Wis. Stats.
If the Zoning Administrator determines that a parcel of land, whether vacant, partially developed, or fully developed, contains one or more development constraints that would preclude the normal use of the parcel for a use that is otherwise permitted in the zoning district in which it is located, he or she shall render a written determination that states the best available facts related to the development constraint and other reasoning as may be appropriate. Examples of development constraints include unfavorable topography, rock formations, shallow depth to bedrock, unstable or otherwise unsuitable soils, stormwater runoff, inadequate drainage, and high groundwater. Once such a determination has been made, the Zoning Administrator, Building Official, or other governmental official or body shall not issue a development order or other approval authorizing the development in the area subject to the development constraint. Because a determination rendered by the Zoning Administrator pursuant to this section is an administrative decision, the property owner shall have the right to appeal such determination consistent with the procedures and requirements in Article 6 of this chapter. The Zoning Administrator may reconsider his or her determination at any time and render a new determination if new or additional facts become known or if the facts upon which the determination was made are not accurate.
The Zoning Administrator is authorized to prepare a map showing those properties that have an active conditional use permit and to amend the same from time to time.
