Idaho
Summary
Idaho delegates zoning authority to both cities and counties through the Local Land Use Planning Act (LLUPA), codified at Idaho Code Title 67, Chapter 65 (§§ 67-6501 et seq.), enacted in 1975. Section 67-6503 makes the delegation mandatory, directing that "every city and county shall exercise the powers conferred by this chapter," and § 67-6511 is the operative grant authorizing each governing board to enact a zoning ordinance establishing zoning districts and regulating building height, size, lot occupancy, population density, and the location and use of buildings, structures, and land. Zoning must conform to a locally adopted comprehensive plan (§ 67-6508) and follow the notice-and-hearing procedures of § 67-6509. There is no statewide zoning authority; planning and zoning power rests with municipalities (over incorporated areas) and counties (over unincorporated areas), grounded in the police power that Article XII, Section 2 of the Idaho Constitution affords cities and counties.

Read the verification audit
Verified against the Idaho State Legislature official statutes (legislature.idaho.gov). (a) Real, current statute: Title 67, Chapter 65 "Local Land Use Planning" is the live codification. Confirmed current sections including 2025 versions on Justia. (b) Genuinely the zoning enabling authority: This is LLUPA, Idaho's land use enabling act. - 67-6501 = short title "Local Land Use Planning Act," purpose to promote health/safety/general welfare. - 67-6503 ("Participation of local governments") states verbatim: "Every city and county shall exercise the powers conferred by this chapter" — confirming mandatory delegation as claimed. - 67-6511 ("Zoning ordinance") is the operative grant: each governing board shall establish one or more zones/zoning districts, regulating height/number of stories/size/lot occupancy/yards/density of population/location and use of buildings and structures, in accordance with the comprehensive plan and the notice/hearing procedures of 67-6509. Matches the claimed summary closely (including the standards language). - Comprehensive plan requirement (67-6508) and notice/hearing (67-6509) cross-references are accurate. (c) Authority model: county_and_municipal is accurate — 67-6503 binds both cities and counties; cities zone incorporated areas, counties zone unincorporated areas. No statewide zoning authority. Correct. MINOR CORRECTION (does not affect verification): The claimed range "§§ 67-6501 to 67-6538" understates the chapter, which currently runs through at least 67-6540 (e.g., 67-6540 siting of telecommunications/broadband). The "et seq." phrasing and the specific operative grants cited (67-6503, 67-6511) are correct, so this is a non-material endpoint imprecision rather than a citation error. 1975 enactment date confirmed.
