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 Energy Conservation Code (IECC) — Idaho Energy Conservation Code (2020 Edition amendments)
- 2018 International Mechanical Code (IMC)

Permit types & fees
New Residential Building Permit
Required for new one- and two-family dwelling construction in Middleton. Applied for through the CitizenServe online portal or in person at 1103 W Main St. A $250 building permit deposit is required at application (25% of building permit fee applies toward residential plan review, paid within 30 days or the deposit is forfeited).
From$250.00Electrical 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).
From$130.00Plumbing 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.
From$130.00Mechanical / 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.
From$130.00Accessory Structure Permit
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.
From$75.00Solar 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.
From$60.00valuation-basedEV Charger / EVSE Permit
Middleton has no separate permit type or fee line item for EV charging station (EVSE) installation. The City runs its own electrical permitting and inspection through the City Building Department rather than routing electrical work to Idaho DOPL, so a Level 1 or Level 2 charger circuit added to an existing home is billed under the same 'Existing Residential' branch-circuit fee category as any other electrical alteration.
From$65.00valuation-basedNew Commercial Building Permit
Required for new commercial construction, additions, and any change of occupancy in Middleton, per IBC Sections 105.1 and 111.1. Applied for through the CitizenServe online portal. A $1,000 New Commercial Building Permit Deposit is required at application (the Commercial Building Plan Review Fee, 65% of the building permit fee, applies toward the deposit and must be paid within 30 days or the deposit is forfeited).
From$1,000.00Tenant Improvement (TI) Permit
Required for interior alterations to existing commercial space in Middleton — including work to finish and convert a building shell from Certificate of Completion to Certificate of Occupancy, and any project where the occupancy of record has not been previously established. Applied for through the CitizenServe online portal. A $500 Tenant Improvement Building Permit Deposit is required at application (the 65% Commercial Building Plan Review Fee applies toward the deposit, due within 30 days or the deposit is forfeited). Distinct from the City's separate $75 Commercial Occupancy Only Permit, which covers a tenant moving into an already-permitted space of the identical occupancy classification with zero proposed alterations.

Tips & gotchas
- Middleton has its own City Building Department, distinct from the Canyon County Building Department — do not confuse Middleton's permitting jurisdiction with the county's.
- Middleton adopts building/residential/energy/existing-building codes AS ADOPTED BY THE STATE OF IDAHO (2018 IBC/IRC/IECC/IEBC base editions with Idaho amendments) rather than publishing its own distinct local code-edition amendments — verified against the DOPL 'Idaho Adopted Codes' bulletin.
- Middleton City Code 4-1-1 sets a 200-square-foot threshold for when a building permit is required for any structure or accessory structure — confirm this before assuming a small building is permit-exempt.
- Middleton self-administers electrical, plumbing, and mechanical permitting and inspections through its own Building Department with named trade inspectors (Electrical: Shane Vigil; Plumbing: C.J. Schoonover; Mechanical: Terry Medley) — it does not route these trades to Idaho DOPL.
- Fire code compliance (2018 IFC) is administered separately by the Idaho State Fire Marshal's office, not the City Building Department.
- All permits are applied for and issued through the CitizenServe online portal; trade permit forms state to allow 24 hours for permit processing.
- Permits applied for after construction has already started are charged double the permit fee per City Fee Schedule Resolution 296-10.
- No Middleton-specific plan-review turnaround timeline (in business/working days) for the New Residential Building Permit could be located after exhaustive search of the City website, Fee Schedule, and permit application forms — the Building Department's own page notes a 'high-volume period' with permits processed in the order received, with no stated day count. Contact (208) 585-3133 for current estimates.
- Fee schedule effective October 1, 2025 (Resolution 526-25, adopted August 20, 2025) — building permit deposits are $250 for new residential, $75 for small projects, $500 for tenant improvement, and $1,000 for new commercial.
- Water and sewer connection fees, City Parks impact fees, and Transportation impact fees are charged separately from the building permit fee and can substantially increase total project cost for new construction — verify current rates with Public Works and Planning before budgeting.
- The City's fee schedule was reissued as Resolution 544-26 (effective 7/15/2026) to temporarily decrease sewer connection fees; all other fee lines (including the commercial/TI deposits above) are unchanged and still cite their original resolution numbers within that same reissued document — confirmed by reading the live document at the City's fee-schedule link as of 2026-08-02.
- Middleton distinguishes three commercial permit products: a New Commercial Building Permit ($1,000 deposit, for new construction/additions/change of occupancy), a Tenant Improvement Permit ($500 deposit, for altering or first-occupying existing commercial space), and a lighter-weight Commercial Occupancy Only Permit ($75, for a tenant moving into an already-permitted space of the identical occupancy classification with zero alterations) — confirmed via the City's Commercial Certificate of Occupancy Only Permit & New Tenant Verification form.
- Commercial building permits will not be issued until the City confirms Sewer & Water Connection fees and all applicable Impact, Civil Engineering, and Fire Department fees have been paid — this is a distinct gating step from the building permit fee/deposit itself (City of Middleton Online Permitting and Registration Instructions).
