Black Hawk County, IA Parking Rules: Loading Zones (2026)

010, in the zoning title's off-street parking chapter, requires that any industrial, commercial, business, trade, institutional or recreational use in the 'C' commercial or 'C-M' commercial-manufacturing district provide off-street parking and vehicle storage space. Subsection (B) covers access: where a parking lot does not abut directly on a public or private street, road, alley or easement of access, the property owner must build an access drive leading to the required loading or unloading spaces and parking or storage areas. That drive must be at least 10 feet wide for a dwelling and at least 20 feet wide for every other use, sized so vehicles can maneuver without spilling into a public right-of-way.

The same access drive or easement cannot sit inside an agricultural or residence district unless it serves a permitted use located in that district. Subsection (A) sets companion standards: a parking space must hold at least 180 square feet plus maneuvering room, no parking area may total less than 1,000 square feet except for dwellings and small retail stores under 1,000 square feet, and any surface used for parking other than residential use needs County Engineer approval. Table 2 in the same chapter then sets per-use parking ratios, from one space per 200 square feet for a veterinary clinic to three spaces per lane at a bowling alley.

Enforcement runs through the County Zoning Administrator, who reviews site plans before a zoning permit issues. None of this reaches inside Waterloo, Cedar Falls, Evansdale, Hudson, La Porte City, Dunkerton, Gilbertville, Elk Run Heights or Raymond, each of which enforces its own municipal parking and loading code.
