This is PermitBase’s published record for Unincorporated Bonneville County as of 2026-07-20. It has since been superseded — see the current record. A historical record reflects what PermitBase had verified at that time; it may not capture a real-world change the jurisdiction had made but PermitBase had not yet verified, and it includes any errors we later corrected. Snapshots are never edited retroactively.

Residential Building Permit (New Construction / Addition)
Required for new single-family dwellings, additions, and structural alterations in unincorporated Bonneville County, governed by the 2018 IRC/IBC and related codes adopted under Bonneville County Code § 150.01. The Planning, Zoning, and Building Department (Planning and Zoning Director Naysha Foster) administers plan review and inspections. As of January 20, 2026, the county also administers electrical and plumbing permits/inspections for the same project in-house rather than routing them to the state. Applications and inspection scheduling are submitted through the county's online CityWorks PublicAccess permitting portal.

Requirements
- Building permit required for new residential construction, additions, and structural alterations in unincorporated Bonneville County
- Submit application through the county's online CityWorks PublicAccess permitting portal

- Electrical and plumbing scopes of work on the same project are now permitted and inspected directly by Bonneville County (as of 1-20-2026) rather than by the State of Idaho
- Agricultural buildings are exempt from the building code itself but must still meet zoning placement/setback rules and the IBC § 202 agricultural-building definition plus County Assessor confirmation of agricultural-use land under Idaho Code § 63-604 to qualify for the exemption
- Work commenced before permit issuance is subject to double permit fees

Solar Photovoltaic (PV) Permit
Required for installation of rooftop or ground-mount solar photovoltaic systems in unincorporated Bonneville County. As of January 20, 2026, Bonneville County took over processing of electrical and plumbing permits (and inspections) within the county's jurisdiction — a function previously performed by the State of Idaho. This makes Bonneville County one of the few counties in this database that now self-administers BOTH the building/structural AND electrical portions of a solar installation, rather than routing electrical work to DOPL. No published fee schedule (for either the building or the new electrical permit function) or solar-specific fee line item could be located as of this review — a genuine, recently-created gap rather than an omission.

Requirements
- Building permit required for the structural/mounting portion of a solar PV installation, issued by Bonneville County Planning, Zoning, and Building
- Electrical interconnection permit is now issued DIRECTLY by Bonneville County itself (as of January 20, 2026) rather than the State of Idaho DOPL — this is a recent jurisdictional change specific to this county and does not apply to neighboring Idaho counties in this database that still route electrical work to DOPL
- Does not apply within the city limits of Idaho Falls, Ammon, Iona, Ucon, Ririe, Swan Valley, or Irwin, which operate their own separate permit systems
- Apply via the CityWorks PublicAccess online portal or contact Planning & Zoning directly at 208-524-7920

EV Charger / EVSE Electrical Permit
Installation of an electric vehicle charging station (EVSE) in unincorporated Bonneville County requires an electrical permit. As of January 20, 2026, Bonneville County processes electrical permits and performs electrical inspections directly, in-house — the State of Idaho (previously via DOPL/Division of Building Safety) no longer provides this service here, making Bonneville the only Idaho county in this database to self-administer electrical permitting rather than routing it to DOPL. No fee schedule for the county's newly self-administered electrical permit function (EVSE or otherwise) has been published on the county website as of this verification — the Building & Zoning Applications, Building Permit & Zoning Fees, and Resolutions pages return no fee content, consistent with this database's residential-building-permit.json and solar-pv-permit.json findings for the same county. Applicants should call ahead to confirm current fees. Re-chased 2026-07-20: checked the Public Works Forms and Fees page (bonnevillecountyidaho.gov/page/public-works-forms-and-fees) and the LocalNews8/KIFI coverage of the county's Jan 20, 2026 takeover of electrical/plumbing permitting — neither publishes a dollar figure for the new electrical permit function; the news coverage confirms only that unpermitted work is subject to a double-fee penalty, not the base fee itself. No fee resolution, ordinance, or fee schedule PDF for Bonneville County's newly self-administered electrical permitting has been published online as of this additional check.

Requirements
- Electrical permit required for EVSE circuit/charger installation — as of January 20, 2026, issued directly by Bonneville County (not DOPL) via the county's CityWorks PublicAccess online portal
- Projects with electrical permits issued before January 20, 2026 continue to be inspected by the State of Idaho until finalized; new applications after that date go through the county
- No published fee schedule exists for the county's new electrical permit function — call Bonneville County Planning, Zoning, and Building at 208-524-7920 or email bonnevillebuilding@gmail.com to confirm current EVSE permit fees before applying
- If the EVSE is paired with new structural work (e.g., a carport/canopy), that structural scope requires a separate Bonneville County building permit
