Sioux City, IA Parking Rules: Driveway Rules (2026)

Sioux City regulates where residents can park on their own lots through the zoning code's residential on-site, off-street parking standards. Subsection 25.05.040.5 opens with a flat rule: no parking space is permitted in any front yard or street side yard. The rule names the street side yard along with the front yard, so it is not limited to the area directly in front of the house.

The exception that follows is limited by vehicle type and by location. It applies to passenger cars, vans, pick-up trucks, or similar vehicles. For a vehicle on that list, the parking space must fit one of the lettered options.

Option A covers a space outside of an enclosed garage, provided the surface is constructed of Portland cement concrete (PCC) or hot-mix asphalt. Those are the only surfaces the item names, so gravel and dirt do not qualify under option A.

Option B applies in the absence of an enclosed garage. In that case the vehicle may sit on a single driveway no greater than 16 feet in width, sited where a garage could lawfully be built. The word "single" and the 16 feet cap work together. A Sioux City lot without a garage gets a single driveway for this purpose, and that driveway cannot be widened past 16 feet to create extra front-yard parking.

The options are joined by "or," so a space needs to satisfy only one of them. What the section does not allow is a front yard or street side yard space that fits neither.

This is a city zoning standard. Woodbury County's unincorporated land is not covered.
