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.

| Building Permit Fee (Total Valuation $0 to $2,000) | $113 | Bonneville County Resolution No. 25-19, 'Fee Schedule for Planning & Zoning Permits' table, recorded as Instrument #1797567 (09/23/2025), effective 10/1/2025 — the current, live fee schedule (supersedes Resolution 24-12; no later resolution supersedes 25-19 as of this verification). Covers building permits, including the residential building permit. |
| Building Permit Fee (Total Valuation $2,001 to $30,000) | $120 for the first $2,000 plus $17.50 for each additional $1,000 or fraction thereof, to and including $30,000 | Resolution 25-19, Fee Schedule for Planning & Zoning Permits |
| Building Permit Fee (Total Valuation $30,001 to $60,000) | $615 for the first $30,001 plus $16.25 for each additional $1,000 or fraction thereof, to and including $60,000 | Resolution 25-19, Fee Schedule for Planning & Zoning Permits |

| Minimum Reinspection Fee | $105.00 | Resolution 25-19, 'Specific Permit Fees' table |
| Electrical or Plumbing Inspection | $105.00 | Resolution 25-19, 'Specific Permit Fees' table — this line item predates the county's January 20, 2026 takeover of electrical/plumbing permitting from the State of Idaho, so it is quoted verbatim rather than assumed to be the full current electrical/plumbing permit fee; call ahead to confirm how it applies post-takeover |

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

| Solar (permit fee) | $210.00 | Bonneville County Resolution No. 25-19, 'Specific Permit Fees' table (Instrument #1797567, recorded 09/23/2025, effective 10/1/2025) — the current, live fee schedule found on the county's Resolutions page (not the separate, unpopulated 'Building Permit & Zoning Fees' page prior chases checked). Listed as a flat category fee alongside Residential Wind Turbines and Cell Tower; the resolution does not separately itemize the structural-mount vs. electrical-interconnection scopes of a solar installation, so this figure is quoted as-is rather than assumed to be all-inclusive. |
| Electrical or Plumbing Inspection (may apply to the interconnection scope) | $105.00 | Resolution 25-19, 'Specific Permit Fees' table — quoted verbatim; this line item predates the county's January 20, 2026 takeover of electrical permitting from the State of Idaho, so it's presented as a documented figure, not confirmed as the exact charge for a solar interconnection permit. Call ahead to confirm. |
| Surcharges applied to permits above | 10% plan review fee + 5% Software fee | Quoted verbatim from Resolution 25-19: '*Each permit is subject to a ten percent (10%) plan review fee, and a five percent (5%) Software fee.' |
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. RE-CHASED 2026-07-23: 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) — a scanned PDF with no text layer, missed by prior checks of the separate '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. This 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 still call ahead to confirm.
