Full Breakdown

Under Sioux City Municipal Code § 25.02.180(1), an adult entertainment business cannot be sited within 1,000 feet of another adult entertainment or sexually oriented business, of residential zoning districts (NC, RR, SR, GR, UR, MU, SC), or of a pre-existing school, college, public park, or child care center, and also faces separate 500-foot and 150-foot buffers from certain commercial districts and rail lines. Operating without the required city license (Chapter 4.75) is independently unlawful in Sioux City, Woodbury County, Iowa.

Violations & Fines

Operating an unlicensed adult entertainment or sexually oriented business, or siting one inside a buffer zone, is a misdemeanor; each day of continued violation is a separate offense, and the city may also seek civil injunctive relief.

Frequently Asked Questions

Can an adult entertainment business locate anywhere zoned commercial in Sioux City?
No. Even in a commercial district it must clear 1,000-foot spacing from schools, parks, homes, and other adult businesses, plus 500-foot and 150-foot buffers from certain districts and rail lines.
Does Sioux City require a separate license for these businesses?
Yes. Chapter 4.75 makes it unlawful to operate an adult oriented business in the city without a valid adult oriented business license from the city clerk.
