Minidoka County (Building Authority for Unincorporated County and the Cities of Acequia, Minidoka, Paul, and Rupert) building permits

Tips & gotchas

• IMPORTANT — Minidoka County's Building Department is the building authority for the ENTIRE county, including the incorporated Cities of Acequia, Minidoka, Paul, and Rupert. This is confirmed directly by the county's own Building and Zoning page (minidoka.id.us/179/Building-and-Zoning), which states: 'Minidoka County serves as the Building Department for Minidoka County and the Cities of Acequia, Minidoka, Paul, and Rupert.' None of those four towns operates its own separate building department — residents and contractors in Rupert, Paul, Minidoka, or Acequia should use THIS file (Minidoka County Building Department), not a city-specific jurisdiction file, because no such file exists or would be accurate.
• EXCEPTION: the City of Heyburn — also located in Minidoka County and in fact the county's largest city — maintains its OWN separate building department, distinct from the county's. This is stated on the county's own Other Permitting page (minidoka.id.us/373/Other-Permitting: 'Minidoka County Building Department serves the county plus Cities of Acequia, Minidoka, Paul, and Rupert, while Heyburn maintains its own building department') and corroborated by the Residential/Manufactured Home Packets, which list a separate 'MCFPD' fire district contact for Heyburn (1120 21st Street, Heyburn) distinct from the City of Rupert and 'West End' fire district contacts used for the other four towns. Heyburn should be documented under its own jurisdiction file, NOT this one.
• Electrical and plumbing permits are issued and inspected by the State of Idaho Division of Building Safety (DOPL) at (800) 955-3044 / dopl.idaho.gov — NOT by Minidoka County. This applies uniformly across the county and all four covered cities.
• Septic and drain-field permits go through the South Central Public Health District (Scott Arnell, (208) 678-8221, 485 Roger Ave, Heyburn ID 83336) — a separate agency from the Building Department.
• Zoning contact varies by city even though building permitting is unified: City of Paul and City of Rupert zoning both route through Rick Nay (208-436-7183, the same Building Official who runs the county department); City of Acequia zoning is Matt Darrington (208-260-5280); City of Minidoka zoning is Paul Ross (208-878-3368) — despite different zoning contacts, all four cities' BUILDING permits go through the single Minidoka County Building Department at 715 G Street, Rupert.
• County and city setbacks differ: county parcels require 30 feet from road right-of-way (5 feet side/rear); city parcels (Acequia, Minidoka, Paul, Rupert) require 20 feet from road right-of-way (5 feet side/rear), per both the Residential and Manufactured Home Packets.
• Currently adopted code per the county's own Residential/Manufactured Home Packets is the 2018 IRC; the county's separate Adopted Building Codes page additionally lists 2018 IBC, 2018 IECC, 2018 IEBC, and 2018 IMC, effective January 1, 2021 — no more recent (e.g., 2021 or 2024) code-edition adoption was found published on minidoka.id.us as of 2026-07-04.
• No county-published numeric fee schedule (valuation brackets, flat per-trade fees, or percentage-based plan-review fee) was found online in any form — not on the Building Permits, Residential, Manufactured Homes, or Commercial pages, and not within either downloadable application packet. The county directs fee inquiries to 208-436-7180. This is a materially different situation from Iron County, Utah (whose fee schedule is published as a standalone PDF) — all `fees` arrays in this file are therefore empty rather than populated with invented figures.
• Plan review turnaround is explicitly published as 5-10 business days for BOTH residential and manufactured-home permits, once a complete application is received — applications are processed in the order received, so incomplete submittals cause delays.
• All development on the Snake River Shoreline requires review by the Minidoka County Building and Zoning Department regardless of whether the parcel is in the unincorporated county or one of the four covered cities.
• A permit becomes null and void if construction has not commenced within 180 days of issuance, or if work is suspended/abandoned for 180 days at any point after commencement — this is printed directly on the Permit Agreement section of both application packets.
