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.

Permit types & fees

• Residential Building Permit

  Required for new residential construction and certain improvements in Kuna, including new residences, mobile homes, accessory dwelling units, accessory structures over 200 sq ft, additions, decks over 30 inches above grade, retaining walls over 4 feet, fences, heating/cooling systems, and demolition. Submit plans by email to BuildingPermits@KunaID.gov (application and individual PDFs) plus construction plans (24x36) to Dropbox link provided by the Building Department after application is received. (Re-verified 2026-07-16: all fees, department contact info, and FAQs confirmed unchanged against live sources; Residential Permit Application PDF confirmed still dated Jan 2025.)

  →

• Commercial Building Permit

  Required for new commercial structures, tenant improvements, change of occupancy, rooftop unit additions/replacements, fencing, and accessory structures over 120 square feet. Commercial submittals must be stamped by a licensed design professional. Civil plans require Public Works approval before submitting to the Building Department. Submit application and individual PDFs to CommercialPermits@KunaID.gov; construction plans (24x36) and engineering/structural calcs via Dropbox. Kuna Fire Department review is required and is a separate process. (Verified 2026-07-16: two additional plan-review-fee tiers found on the live fee schedule PDF and added below.)

  →

• Mechanical / HVAC Permit

  Required for any mechanical equipment installation in Kuna. It is unlawful to perform any mechanical equipment installation without first obtaining a mechanical permit from the City of Kuna. Applies to residential and commercial work. (Verified 2026-07-16: re-rendered the live fee schedule PDF to image; the commercial/industrial ×0.02 formula is confirmed exact as printed, not drift — prior audit flag was a false alarm.)

  →

• Electrical Permit

  Required for all electrical installations in Kuna. The Electrical Program exists to protect life, health, and property by ensuring electrical installations comply with the current safety codes. A permit must be obtained prior to commencement of work. Electrical permits are available at the City of Kuna Building Department. (Verified 2026-07-16: commercial/industrial/solar ×0.02 formula confirmed exact on the live fee schedule PDF, not drift; two additional fee tiers above $10,000 were found on the same table and added below.)

  →

• Solar Photovoltaic (PV) Permit

  Required for rooftop or ground-mounted solar photovoltaic installations in Kuna. The City's own Electrical Program fee schedule (Resolution R74-2023A) explicitly bundles solar with commercial/industrial electrical work into a single tiered, contract-value-based fee category — 'Commercial/Industrial/Solar' — rather than pricing solar as its own separate line item or under the residential per-square-foot electrical tiers. Structural/racking attachment is reviewed under the general Building Permit.

  →

• EV Charger / EVSE Permit

  Electric vehicle charging equipment (EVSE) installation in Kuna is an electrical installation, permitted through the City of Kuna Building Department's Electrical Program under the same Electrical Permit Application and Resolution R74-2023A fee schedule used for all other electrical work. The fee schedule has no distinct EV-charger/EVSE line item — a Level 2 EVSE circuit added to an existing residence is billed under the schedule's 'Existing Residence' branch-circuit tier, one installed with new construction falls under the New Single Family Dwelling square-footage tier, and a standalone commercial charging station is billed under the same 'Commercial/Industrial/Solar' contract-value tier used for solar and other commercial electrical work.

  →

• Plumbing Permit

  Required for all plumbing installations in Kuna. The Plumbing Program ensures plumbing practices comply with the Idaho State Plumbing Code (based on the Uniform Plumbing Code). A plumbing permit must be obtained prior to any commencement of work. Plumbing permits are available at the City of Kuna Building Department. (Verified 2026-07-16: commercial/industrial ×0.02 formula confirmed exact on the live fee schedule PDF, not drift; two additional fee tiers above $10,000 were found on the same table and added below.)

  →

• Demolition Permit

  Required for demolition or relocation of structures in Kuna. A separate demolition permit must be obtained before commencing demolition work. (Re-verified 2026-07-16: $30 fee and Jan 2025 application-form date both confirmed unchanged on live sources.)
