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.

  →

• Electrical Permit

  Required for all electrical installations in Middleton, including new residential wiring, service changes, and remodel/repair circuits. Middleton self-administers electrical permitting and inspection through its own City Building Department (does not route to Idaho DOPL).

  →

• Plumbing Permit

  Required for all plumbing installations in Middleton, including new residential piping, fixture additions, and sewer/water connections. Governed by the 2017 Idaho State Plumbing Code (based on the 2015 Uniform Plumbing Code). Self-administered by the City Building Department.

• Mechanical / HVAC Permit

  Required for all mechanical equipment installations in Middleton, including furnaces, HVAC systems, gas lines, and fireplaces. Governed by the 2018 International Mechanical Code and 2018 International Fuel Gas Code. Self-administered by the City Building Department.

  Required for any structure or accessory structure exceeding 200 square feet constructed, remodeled, renovated, or added to within the City of Middleton, per City Code Title 4, Chapter 1, Section 4-1-1.

  →

• Solar PV Permit

  Required for installation of rooftop or ground-mounted solar photovoltaic systems in Middleton. The City's own Electrical Permit form (Attachment B) publishes a dedicated 'Other Installations commercial/industrial/solar' fee category (Category #6) with a cost-based formula, directly naming solar as a covered installation type; the structural/racking scope is permitted through the City's general valuation-based Building Permit. Middleton self-administers both scopes through its own Building Department — it does not route the electrical component to Idaho DOPL.

  →

• EV Charger / EVSE Permit

  The City of Middleton has no separate permit type or fee line item for EV charging station (EVSE) installation. Middleton self-administers electrical permitting and inspection through its own City Building Department (it does not route electrical work to Idaho DOPL, unlike several other small Idaho jurisdictions in this corpus). A Level 1/Level 2 EV charger circuit added to an existing home is billed under the same 'Existing Residential' branch-circuit fee category used for any other electrical alteration.
