Ada County, ID Business Licensing & Operations: Adult Entertainment (2026)

Section 8-4-3(A) grounds the county's adult entertainment separation standards in Idaho Code Section 67-6533's local land use authority and sets three concrete buffers: no adult entertainment establishment may locate within 1,000 feet of another existing adult entertainment establishment, within 2,500 feet of any religious land use, or within 2,500 feet of any school. Measurement follows the standard method set out in Section 8-4-1(E) for measuring separations between uses across the zoning code, so the distance runs by that section's methodology rather than an arbitrary lot-line measurement.

To document compliance, the application must include evidence certified by a professional land surveyor licensed in Idaho showing the proposed site meets every one of those separations; without that certification the Development Services Director cannot issue the zoning certificate. Subsection B layers on signage duties beyond the general Title 8 sign code: every adult entertainment establishment must comply with Section 8-3-12 like any other business, and must additionally post a legible door sign at each entrance stating that persons under 18 are not permitted, sized between one half square foot and one square foot.

That entrance sign does not need administrative sign approval under Section 8-3-12, unlike other exterior signage on the property. Because the county's zoning code treats adult entertainment as a distinct principal use category subject to Chapter 4's use-specific standards, an establishment that cannot meet the spacing math, or that skips the surveyor certification, is not eligible for a zoning certificate regardless of the underlying commercial or industrial district's other permitted uses.
