Codes adopted
Idaho adopts a statewide baseline building code set under the Idaho Building Code Act (Idaho Code Title 39, Chapter 41) and IDAPA rules administered by the Idaho Division of Occupational and Professional Licenses (DOPL). Effective January 1, 2021, the statewide baseline includes the 2018 International Building Code (IBC), 2020 Idaho Residential Code (based on the 2018 IRC Parts I–III and IX with Idaho amendments), 2020 Idaho Energy Conservation Code (based on the 2018 IECC with Idaho amendments), 2018 International Existing Building Code (IEBC), 2018 International Mechanical Code (IMC), 2018 International Fuel Gas Code (IFGC), and 2018 International Fire Code (IFC). The National Electrical Code is adopted separately by the Idaho Electrical Board (IDAPA 24.39.10), not bundled with the building code: Idaho enforces the 2023 NEC, effective July 1, 2024 (the state used the 2017 NEC with amendments before that and skipped the 2020 edition). Local jurisdictions must enforce the state baseline and may adopt amendments only where those amendments are at least as stringent as the state-adopted editions; local amendments may not be less restrictive. Enforcement is local — each city or county issues permits and performs inspections. Always confirm the current adopted edition and any local amendments with your specific jurisdiction before submitting plans.
- 2018 International Building Code (IBC) — adopted per Ord. 2017-03 (12-18-2017), amended to the 2018 edition and further amended by Ord. 2020-03 (9-14-2020); codified as Power County Code section 8-1-13, with local amendments at section 8-1-13-1
- 2018 International Residential Code (IRC) — same adoption/amendment history (Ord. 2017-03; amd. Ord. 2020-03); parts I, II, III, IV, and IX, plus appendix G (swimming pools/spas/hot tubs), appendix H (patio covers), and accessibility appendices
- 2018 International Energy Conservation Code (IECC) — same Ord. 2017-03/2020-03 adoption
- 2018 International Fire Code (IFC) — same Ord. 2017-03/2020-03 adoption
- 2018 International Existing Building Code (IEBC) — same Ord. 2017-03/2020-03 adoption

Permit types & fees
Residential Building Permit (New Construction / Addition)
Required for new single-family dwellings, additions, structural alterations, and outbuildings over 120 sq ft in unincorporated Power County. Applications are submitted on the shared Consolidated Building-Development Permit Application (used jointly by Power County, American Falls, and Rockland — applicant selects 'Power County' as the jurisdiction). Reviewed and inspected by the Power County Building Administrator.
From$24valuation-basedAgricultural Structure Permit (Zoning Permit + Ag Certification)
Agricultural buildings in unincorporated Power County require a Zoning Permit and a notarized Agricultural Building Certification Statement, recorded with the Power County Recorder's Office. Qualifies only for structures used exclusively to house farm implements, hay, grain, poultry, or livestock — not for human habitation, employment where products are processed/treated/packaged, or public use.
See fee scheduleSolar PV Permit
Power County has a detailed Solar Farms ordinance (Title 10, Chapter 23) governing utility-scale solar development (the county is home to the 300 MW Moon Crater Solar and Storage Project) — but Section 10-23-7(A) explicitly EXEMPTS 'residential use solar facilities' from the Conditional Use Permit that chapter otherwise requires for all other solar installations. A residential/personal-use system is separately defined in the ordinance (Section 10-23-3) as a 'solar energy array with a total nameplate capacity of 200 kilowatts or less, associated with single or two-family dwellings, or personal use.' A qualifying residential system is instead processed as the county's standard valuation-based Building Permit (the same mechanism as other residential construction), with electrical interconnection separately regulated by the Idaho Division of Occupational and Professional Licenses (DOPL), since Power County has deleted electrical/mechanical/plumbing permitting from its own local code.
From$24valuation-basedEV Charger / EVSE Permit
Power County's adopted Building Code Ordinance (Title 8) lists only the IBC, IRC, IECC, IFC, and IEBC — no county-adopted NEC edition — and the state's own Inspector List with Schedules assigns Power County electrical inspections to a State of Idaho electrical inspector (Shane Lott), confirming that electrical work in unincorporated Power County is regulated by the Idaho Division of Occupational and Professional Licenses (DOPL, formerly Division of Building Safety), not the county. An EV charger/EVSE installation therefore requires a State of Idaho Electrical Permit through DOPL, not a county permit. DOPL publishes no distinct EV charger/EVSE fee line; a residential EVSE circuit added to an existing home is billed under the homeowner (or contractor) electrical permit fee structure — a base fee plus a per-branch-circuit charge for existing-residence work.
From$65.00Commercial Building Permit (New Construction, Additions & Tenant Improvement/Remodel)
Covers new commercial building construction, commercial additions, and commercial remodels/tenant improvements in unincorporated Power County. There is no separate 'commercial' or 'tenant improvement' permit product, application, or fee schedule — Power County processes all of this work through the same Building Permit and Consolidated Building-Development Permit Application used for residential construction, with the Building Administrator as reviewer/inspector. What actually differs from residential: the work is governed by the county's adopted 2018 International Building Code (IBC, Power County Code section 8-1-13) rather than the IRC; commercial valuation for fee purposes is established at the contract bid price rather than the sq-ft cost tables; and plan review for new commercial buildings, additions, and remodels is billed at a flat 65% of the building permit fee rather than the general hourly rate. For a tenant-space remodel/build-out that does not change the occupant load, occupancy group, or occupancy use classification, IBC section 111.1.1 (locally added by Ord. 2020-03) allows a Certificate of Completion in lieu of a full Certificate of Occupancy — this is the county's functional substitute for a distinct TI sign-off process.

Tips & gotchas
- Power County shares one Consolidated Building-Development Permit Application with the City of American Falls and the City of Rockland — always check 'Power County' as the work location on the form when the project is in the unincorporated area.
- Power County does NOT issue electrical, plumbing, or HVAC/mechanical permits. These are regulated solely by the State of Idaho (IC 54-1001, IC 54-2601) — obtain them from the Idaho Division of Occupational and Professional Licenses (DOPL) (DOPL/DBS) at dopl.idaho.gov/permits or 1-800-955-3044.
- A Power County Highway Permit (208-226-2661) and, where applicable, a septic permit from the State Health District (208-226-5094 or 208-478-6320) are prerequisites — secure these before submitting the building permit application.
- Standard review is 10-14 days; re-roofing, re-siding, and sign permits can be issued same-day with complete information.
- Permits lapse after 180 days; extensions require verified active work and meeting county criteria.
- Starting work before a permit is issued triggers an investigative fee equal to the permit fee, in addition to the permit fee itself.
- 80% of the building permit fee is refundable if no work has begun, but you must request the refund within 30 days of paying the fee.
- Design criteria apply county-wide: 32-inch frost depth, 90 mph wind speed, Seismic Zone D-1, Climate Zone 5, and an elevation-based snow load table ranging from 35 lb (below 4,600 ft) to 100 lb ground load / 125 lb roof live load (6,800+ ft).
- Six inspections are mandatory in sequence: Footing, Foundation, Concrete Slab/Under-Floor, Frame, Lath/Gypsum Board, and Final. Contact the Building Administrator to schedule each one before proceeding to the next phase.
- Agricultural buildings need a notarized Agricultural Building Certification Statement that gets recorded against the property title — it only applies to structures used exclusively for farm implements/hay/grain/poultry/livestock storage, not habitation or public/commercial use.
- Power County's building code ordinance (originally adopted 2017, recorded 2018) amended all five codes to the 2018 edition by Ord. 2020-03 (9-14-2020), per the live American Legal Publishing code library page. See codesAdopted above for the editions and citation.
- There is no separate 'commercial building permit' or 'tenant improvement permit' product in unincorporated Power County — new commercial construction, additions, and remodels/TI all route through the same Building Permit and Consolidated Building-Development Permit Application as residential work, governed by the 2018 IBC. A tenant-space remodel that doesn't change occupant load/occupancy group/occupancy classification can get a Certificate of Completion instead of a full Certificate of Occupancy (IBC section 111.1.1, locally added by Ord. 2020-03) — see the Commercial Building Permit entry above.
