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.

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 the last verification — 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

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, an arrangement unique among the Idaho counties covered here, which otherwise route electrical permitting to DOPL. The county's current fee schedule, Resolution No. 25-19 (Instrument #1797567, recorded 09/23/2025, effective 10/1/2025), is published on the county's official Resolutions page (bonnevillecountyidaho.gov/page/resolutions) as a scanned PDF, separate from the 'Building Permit & Zoning Fees' content page. It lists an 'Electrical or Plumbing Inspection' fee of $105.00 and a 'Minimum Inspection Fee For All Codes' of $105.00, each subject to a 10% plan-review and 5% software surcharge. That resolution predates the January 20, 2026 electrical-permitting takeover, so the figures are quoted as the documented, currently-in-force fee schedule rather than confirmed as unchanged for the new electrical-permit function specifically — applicants should call ahead to confirm.

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
- Per Resolution 25-19 (the county's current live fee schedule), an Electrical or Plumbing Inspection is $105.00 and the Minimum Inspection Fee For All Codes is $105.00, each subject to a 10% plan-review and 5% software surcharge — confirm with Bonneville County Planning, Zoning, and Building at 208-524-7920 or bonnevillebuilding@gmail.com how these apply to a specific EVSE permit
- If the EVSE is paired with new structural work (e.g., a carport/canopy), that structural scope requires a separate Bonneville County building permit

Commercial Building Permit (New Construction / Tenant Improvement)
Required for new commercial construction and for alteration/tenant-improvement (TI) work in existing commercial buildings in unincorporated Bonneville County. Bonneville County Code § 150.01 does not create a legally distinct 'commercial' permit type or a separate TI permit — commercial and TI projects go through the same Building Permit process as residential projects (same Chapter 150, same CityWorks PublicAccess portal, same Planning, Zoning, and Building Department), governed by the 2018 IBC for new construction and the 2018 IEBC for alterations/additions to existing buildings. What IS confirmed as distinct from residential, from Bonneville County Resolution No. 25-19 (the county's live fee schedule, read directly as a PDF on 2026-08-02): (1) commercial projects are valued for fee purposes at the project's actual Contract Price, not via the county's per-square-foot residential valuation schedule, and (2) there is a separate, higher 'Commercial Fire Sprinkler Permits' fee ($420.00) distinct from the residential fire-sprinkler fee ($210.00). As of January 20, 2026, Bonneville County also processes electrical and plumbing permits and inspections in-house for commercial projects, the same as for residential.

Requirements
- Building permit required for new commercial construction and for tenant-improvement/remodel/alteration work in existing commercial buildings, issued by Bonneville County Planning, Zoning, and Building under Bonneville County Code § 150.01
- Bonneville County has no separately named 'tenant improvement' or 'TI' permit product: (a) Bonneville County Code Chapter 150 (§ 150.01) creates only one Building Permit category, with no TI-specific subsection; (b) Resolution No. 25-19's fee schedule (page 3) contains one 'Commercial Permits' valuation line and no separate TI/remodel/alteration fee item; (c) the county's 'Building & Zoning Applications' and 'Building Inspection' content pages both display 'No items found', so no TI-specific application or checklist is published there either. TI/remodel work in existing commercial space is submitted as a standard Building Permit application and reviewed under the 2018 IEBC (adopted at § 150.01(A)(7)) rather than the new-construction provisions of the 2018 IBC.
- New commercial construction is reviewed under the 2018 IBC, plus the 2018 IECC, 2018 IFGC, 2018 IMC, 2018 IFC (with State Fire Marshal amendments), 2023 NEC, and 2017 Idaho State Plumbing Code, all adopted under § 150.01(A)
- Commercial permit valuation for the fee table is based on the project's actual Contract Price — confirmed from Resolution No. 25-19's 'Square Footage Values' table, which lists 'Commercial Permits: Contract Price' as its own row, distinct from the per-square-foot values used for a 'Residence.' Applicants should be prepared to document the contract/construction cost to establish this valuation.
- The 2018 IBC as adopted includes State Building Code Board rules providing ADA and Federal Fair Housing Act accessibility-guideline equivalency (§ 150.01(A)(1)), applicable to commercial occupancies
- Electrical and plumbing scopes of work on a commercial project are permitted and inspected directly by Bonneville County (as of January 20, 2026) rather than by the State of Idaho, the same change that applies to residential permits
- If the adopted 2018 IFC requires a fire-sprinkler system for the occupancy, it is permitted separately as a 'Commercial Fire Sprinkler Permit' at a higher fee than the residential fire-sprinkler permit
- Submit applications and schedule inspections through the county's online CityWorks PublicAccess permitting portal
- Does not apply within the city limits of Idaho Falls, Ammon, Iona, Ucon, Ririe, Swan Valley, or Irwin, which operate their own separate commercial permit systems
- Work commenced before permit issuance is subject to double permit fees per county policy
