Black Hawk County, IA Home Business: Customer Traffic Restrictions (2026)

190(D) and (F) control the off-site footprint of a home occupation on unincorporated land outside the county's cities. Subsection D prohibits any evidence of the business being conducted within the dwelling that is perceivable at or beyond the lot lines, and it lists excessive traffic generation in the same sentence as outside storage, displays, noise, odors, smoke, vibration, heat, dust and electrical disturbances, treating traffic exactly like those other off-site nuisances. Subsection F then requires that customer parking be provided on the premises and be kept as inconspicuous as possible, rather than lining a public road or spilling onto a neighbor's land.

Together the two subsections mean a home business cannot bring in enough customer or delivery traffic to be noticeable from outside the lot, and any parking it generates has to be screened or tucked out of view rather than displayed along the frontage. 200, which carries over the identical customer-parking and off-lot-evidence language for businesses run out of a garage or pole barn rather than the house itself. 190 allows. These standards date to Ordinance 36 in 1995 and were carried forward unchanged through the county's 2014 zoning recodification.
