Full Breakdown
Sioux City Municipal Code § 25.03.090.4 allows rainwater harvesting as an accessory residential use citywide. Homeowners may keep one rain barrel per single-family dwelling, capped at 55 gallons. Barrels must sit behind the principal building, or if placed in an interior side or street side yard, be screened by an opaque fence or landscaping one foot taller than the barrel. Barrels need at least a two-foot setback from interior side or rear property lines and must be screened to keep mosquitoes out unless the lid feeds directly from a gutter downspout with no other openings.
Violations & Fines
Zoning enforcement can require relocation, rescreening, or removal of an oversized, unscreened, or improperly placed rain barrel that doesn't meet the accessory-use standard.
