Zoning and Unified Development Code (UDC)

Each piece of property within the City of Spokane has a specific zone assigned to it. The zoning category determines what uses are allowed on the property. To find the zoning a piece of property, click here: Spokane GIS - CityMap. The City of Spokane consolidates all of the development regulations and guidelines into a Unified Development Code (UDC) found in Spokane Municipal Code Title 17.

The UDC, or “Zoning Code”, contains the descriptions of the City's zoning categories, the uses allowed,, and the development standards for each zone. The development standards provide information such as required building setbacks, height limitations, lot coverage, landscaping requirements, and parking ratios. A quick summary of allowed uses for each zone is available here.
