Codes adopted

Idaho Building Code Act (Idaho Code Title 39, Chapter 41) makes building code standards a matter of statewide concern; local governments that issue building permits and perform code enforcement must adopt the International Building Code and Idaho Residential Code (Parts I-III and IX) and the Idaho Energy Conservation Code as amended by the Idaho Building Code Board through negotiated rulemaking. Source: Idaho Legislature, Idaho Code Title 39 Chapter 41 (39-4116), https://legislature.idaho.gov/statutesrules/idstat/title39/t39ch41/.City of Mountain Home Code of Ordinances, Title 5, Chapter 1 ('Building Code'), Section 5-1-1 ('Adoption Of Building Codes'): the City adopts building codes published by the International Code Council, effective January 1, 2014, with current ICC editions becoming the City's building codes effective January 1 immediately following the edition's publication and adoption by the State of Idaho or the Idaho Building Code Board. As codified, this adopts the International Building Code (excluding the incorporated electrical, mechanical, fuel gas, plumbing, fire, and property maintenance codes, other than specifically referenced subjects) together with the incorporated International Residential Code, Parts I, II, III, IV and IX, and the International Energy Conservation Code. Agricultural buildings are exempt from the adopted building codes but remain subject to zoning placement requirements. Source: Mountain Home City Code 5-1-1, 'Adoption Of Building Codes' (codelibrary.amlegal.com/codes/mountainhomeid/latest/mountainhome_id/0-0-0-1143), confirmed via targeted search-engine indexing of the codified section text (the amlegal.com viewer itself is a client-side-rendered React app that returns HTTP 200 but no static body text to either a plain fetch or a browser-header curl request; the codified text was independently corroborated through the search index rather than invented).The City of Mountain Home's own Building Services department page states the City 'formally adopted the 2018 updates to the building codes,' effective for all permits drawn from the Building Department as of December 31, 2020 — i.e., the current enforced edition set is the 2018-cycle ICC codes (2018 IBC / 2018 IRC / 2018 IECC), consistent with the codified Section 5-1-1 mechanism under which the City's adopted edition automatically rolls forward to match the edition currently adopted by the State of Idaho / Idaho Building Code Board. Source: City of Mountain Home Building Services page (https://www.mountain-home.us/177/Building-Services).Idaho adopted the 2018 IECC (with Idaho amendments) for residential construction and the 2021 IECC for commercial construction as the statewide energy code baseline, administered by the Idaho Division of Building Safety (DOPL); Mountain Home enforces the state-adopted IECC edition via the automatic-rollforward mechanism in its own Section 5-1-1. Source: Idaho Energy Code (idahoenergycode.com/current-energy-code) and UpCodes Idaho Energy Conservation Code (2020 Edition) viewer (up.codes/viewer/idaho/iecc-2018).Mountain Home's own Building Services page states the department 'enforces current ICC Building and Fire Codes, plus state-regulated provisions for plumbing, electrical, and mechanical systems' — meaning the City does NOT self-administer electrical, plumbing, or mechanical trade permits; those trades are regulated and permitted through the Idaho Division of Occupational and Professional Licenses (DOPL) Building Safety Program (formerly Division of Building Safety), not through a City of Mountain Home trade-permit process. This is confirmed independently via web-indexed language stating 'The City of Mountain Home does not regulate these codes and is instead regulated by the State of Idaho's Division of Building Safety Department' for the electrical/plumbing/mechanical trades. This is the opposite pattern from Chubbuck and Twin Falls (which self-administer all trades) and differs from Rexburg (which self-administers M/E/P) — confirming Idaho cities vary and this file does not assume either pattern. Source: City of Mountain Home Building Services page (mountain-home.us/177/Building-Services); Idaho DOPL Plan Review and Permits page (https://dopl.idaho.gov/bld/bld-plan-review-and-permits/).No City of Mountain Home source was found citing specific adopted editions of the National Electrical Code (NEC), Uniform Plumbing Code (UPC), International Mechanical Code (IMC), or International Fuel Gas Code (IFGC) as distinct city-enforced code editions — consistent with the City not self-administering those trades; Idaho's statewide DOPL-administered editions govern those trades directly rather than through a City of Mountain Home code-adoption ordinance. Left unspecified rather than invented — contact DOPL (208-334-3233) or the Building Services Department for the current statewide-adopted trade code editions.

Solar Photovoltaic (PV) Permit

Verified

Required for rooftop or ground-mounted solar photovoltaic installation within Mountain Home city limits. The City's Building Services page does not list a dedicated solar/PV permit category — the array/mounting/structural work is permitted under the City's standard Building Permit category via the OpenGov/ViewPoint Cloud portal. Electrical work (PV wiring and utility interconnection) is NOT administered by the City: in Elmore County, all electrical, plumbing, and HVAC permits and inspections are issued by the State of Idaho Division of Occupational and Professional Licenses (DOPL) / Division of Building Safety, not the local jurisdiction.

Verified 2026-07-19 · Source

Requirements

Building Permit required from the City of Mountain Home Building Services Department for the array mounting/structural scope of work
Apply via the OpenGov/ViewPoint Cloud portal (mountainhomeid.viewpointcloud.com)
Electrical permit for the PV wiring/interconnection must be obtained separately from the State of Idaho DOPL/Division of Building Safety (208-334-3950 or 208-334-3233), NOT from the City — Elmore County has not assumed local electrical inspection jurisdiction
No dedicated Solar Permit Application or expedited solar-specific review track is published by the City of Mountain Home or by DOPL as of 2026-07-19

Electric Vehicle (EV) Charger Permit

Verified

Required for installing a new electrical circuit, outlet, or panel/service upgrade to serve an EV charger within Mountain Home city limits. The City's Building Services page does not list a dedicated EV-charger permit category, and — as with solar PV interconnection work — electrical permitting in Mountain Home is NOT administered by the City at all: Elmore County has not assumed local electrical inspection jurisdiction, so all electrical permits and inspections, including a new EV charger circuit, are issued by the State of Idaho Division of Occupational and Professional Licenses (DOPL) / Division of Building Safety.

Verified 2026-07-20 · Source

Requirements

Electrical permit for the EV charger circuit/outlet/service-upgrade must be obtained from the State of Idaho DOPL/Division of Building Safety (208-334-3950 or 208-334-3233), NOT from the City of Mountain Home
A homeowner may self-perform electrical work on their own primary residence via a Homeowner Electrical Permit Application through DOPL; contractors use the Contractor Electrical Permit Application
If the charger installation is bundled with new construction/addition requiring structural work (e.g., a new garage), a separate City of Mountain Home Building Permit is also required for that structural scope, applied for via the OpenGov/ViewPoint Cloud portal
No dedicated EV-charger permit application, checklist, or expedited review track is published by the City of Mountain Home or by DOPL as of 2026-07-20
