Oshkosh Zoning & Land Use Guide
Key Zoning Facts
Oshkosh Zoning Overview
Oshkosh is a city in Wisconsin with approximately 66,816 residents, located in Winnebago County. The city manages land use and development through its local zoning ordinance, which divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.
Wisconsin has a statewide building code framework. Residential construction is governed by the Uniform Dwelling Code (SPS 320-325), and commercial construction follows the Commercial Building Code (SPS 361-366). Local jurisdictions enforce these codes and may adopt additional requirements.
