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 and cooling systems, and demolition. Submit plans by email to BuildingPermits@KunaID.gov (application and individual PDFs), plus construction plans (24x36) to the Dropbox link the Building Department provides after the application is received. The Residential Permit Application PDF is dated Jan 2025.
From$70Commercial 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.
From$200Mechanical / 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.
From$93.00Electrical 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.
From$65Solar 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.
From$60EV 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.
From$65valuation-basedPlumbing 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. Commercial and industrial plumbing fees run on a ×0.02 formula, and the fee table continues into additional tiers above $10,000 — see the fees below.
From$130Demolition Permit
Required for demolition or relocation of structures in Kuna. A separate demolition permit must be obtained before demolition work begins. The fee is $30 and the current application form is dated January 2025.
