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 (New Construction / Additions)
Required for new single-family dwellings and additions in Ketchum. Covers structural construction, framing, envelope, and associated systems reviewed against the 2018 IBC/IRC/IECC as locally amended. As of February 27, 2026, the City buckets permit review into Short/Medium/Standard timelines based on project complexity; new construction and additions fall in the Standard tier.
From$24.75valuation-basedCommercial Building Permit (New Construction, Additions, Remodels & Tenant Improvements)
Covers new non-residential construction, commercial additions, and commercial interior or exterior remodels and tenant improvements in Ketchum. There is no separate commercial or tenant-improvement permit product — these projects go through the same Building Permit categories used for residential work (New Construction, Additions, Internal Remodel, External Repair & External Remodel) via the CommunityConnect portal, with plans for non-residential structures reviewed against the 2018 IBC rather than the 2018 IRC used for one- and two-family dwellings, per Ketchum Municipal Code Title 15. The Building Permit fee table, the 65% Plan Check Fee, and the added 70% Planning & Zoning and 70% Fire Department Plan Check fees are the same for commercial and residential projects; the Development Impact Fee is the one line that differs, charged per square foot for commercial use rather than as a flat per-unit amount. Non-residential and mixed-use exterior work also triggers Design Review under the City's Land Development Code in every zoning district, not just the downtown Community Core.
From$24.75valuation-basedResidential Remodel / Repair Permit
Covers internal and external remodels, internal/external repairs, siding replacement, decks, and window/door replacement in Ketchum. As of the February 2026 process update, these project types are grouped into Short and Medium review tiers with streamlined affidavit-based review for less complex scopes.
From$24.75Re-Roof Permit
Required for roof replacement/re-roofing in Ketchum. As of February 2026, re-roofs use a Building Affidavit in place of a full Building Plan Check and are the only permit type exempted from the mandatory pre-final inspection step.
$24.75Solar Photovoltaic (PV) Permit
Required for rooftop or ground-mounted solar PV installation in Ketchum. The City issues a flat-fee Solar Permit for the structural/building portion (using a Building Affidavit and CAP Affidavit in place of full review); the electrical interconnection is separately permitted and inspected by the State of Idaho Division of Building Safety (DBS/DOPL), not the City.
From$100Electrical Permit (State of Idaho)
The City of Ketchum does not issue electrical permits. All electrical work in Ketchum — including new construction wiring, panel upgrades, circuits, and fixture installation — is permitted and inspected directly by the State of Idaho Division of Building Safety (DBS) / Division of Occupational and Professional Licenses (DOPL), confirmed on the City's own Inspections page: 'All mechanical, electrical and plumbing inspections are handled by the State of Idaho.'
From$130Electric Vehicle (EV) Charger / EVSE Permit (State of Idaho)
The City of Ketchum does not issue electrical permits. Like all other electrical work, EV charger/EVSE circuit installation is permitted and inspected by the State of Idaho Division of Building Safety (DBS)/DOPL — the City's Inspections page states, 'All mechanical, electrical and plumbing inspections are handled by the State of Idaho.' IDAPA 24.39.10 (Rules of the Idaho Electrical Board) has no dedicated EV charger/EVSE fee category: a new EV charger circuit added to an existing residence is billed under the flat $65 Existing Residential Dwelling Unit Permit fee, per DOPL's currently published electrical board rules — the same statewide schedule that governs Idaho City, Jerome, and Kellogg, ID. DOPL's older Homeowner Electrical Permit Application & Fee Worksheet does carry a grid-connected renewable-energy Plan Check Fee line, but it is scoped to solar and renewable generation interconnection, not EV charging load.
From$65Plumbing Permit (State of Idaho)
The City of Ketchum does not issue plumbing permits. All plumbing work in Ketchum — new fixtures, water heater replacement, re-piping, sewer/water service lines — is permitted and inspected directly by the State of Idaho State Plumbing Board (DOPL), per the City's own Inspections page.
From$130Demolition Permit
Required for demolition of structures in Ketchum, whether an entire structure or internal/partial demolition. Demo-Entire Structure and Demo-Internal Only or Partial Structure are both in the City's Short review tier.
$1,100

Tips & gotchas
- Ketchum does NOT issue electrical, plumbing, or mechanical/HVAC permits. All trade permits and inspections for those disciplines are handled directly by the State of Idaho Division of Building Safety (DBS/DOPL) at dbs.idaho.gov or (208) 332-4700 — this is stated on the City's own Inspections page.
- The City's building permit application and tracking platform is CommunityConnect, used for building, demolition, dig, ROW encroachment, TURP, and solar (structural) permits only.
- As of February 27, 2026, Ketchum re-bucketed all building permit types into Short (7 calendar days), Medium (15 calendar days), and Standard (25 calendar days) first-review timelines, with all additional review rounds fixed at 7 calendar days.
- New permit categories added February 2026: Deck ONLY, Window/Door Replacement LIKE-FOR-LIKE, and Window/Door Replacement WITH CHANGES (replacing the prior single Window/Door Replacement permit).
- A Construction Activity Plan (CAP) is required for all Community Core/downtown projects; a CAP Affidavit substitutes for eligible less-complex project types outside the Community Core.
- All permits except re-roofs now require a mandatory Pre-Final inspection before departmental finals (Fire, Planning, Engineering) and the ultimate Final Building Inspection can proceed.
- Construction activity is limited to 7:30 AM–7:00 PM on weekdays and Saturdays; work is prohibited on Sundays and holidays per Ketchum Municipal Code 8.08.050.14.
- Ketchum ADUs (300–1,200 net livable sq ft) generally only require the standard building permit — no separate ADU permit type or fee schedule exists. ADUs are exempt from parking requirements and design review, and Fire/Parks/Police/Streets impact fees are waived.
- 24-hour advance notice is required for all City-scheduled building inspections; the City-issued permit must be visibly posted on site with approved plans available.
- Plan Check Fee is 65% of the Building Permit Fee; Planning & Zoning and Fire Department each add a further 70% of the Plan Check Fee where applicable.
- Ketchum has no distinct 'commercial building permit' or 'commercial tenant improvement/TI permit' product. The City's own 'When is a Building Permit Required?' guide (ketchumidaho.gov/DocumentCenter/View/345) and its 'Building Permit Changes — February 2026' document (ketchumidaho.gov/DocumentCenter/View/354) name no 'commercial,' 'non-residential,' or 'tenant improvement' permit category anywhere in their exhaustive permit-type/tier lists. New commercial (non-residential) construction and additions route through the exact same generic 'New Construction' / 'Additions' Building Permit type that residential projects use (Standard review tier, 25 calendar days first review) — the only differentiator is which adopted code governs plan review: 2018 IBC for non-residential/commercial structures vs. 2018 IRC for one- and two-family dwellings, per Ketchum Municipal Code Chapter 15.04. Commercial interior remodels/tenant improvements to existing space use the same generic 'Internal Remodel' or 'External Repair & External Remodel' categories (Medium tier, 15 calendar days) that cover residential remodels — no faster/slower track, and no separate TI-specific document or inspection checklist exists.
- Commercial projects DO pay one genuinely distinct fee: the City's Development Impact Fees (Fire/Parks/Police/Streets) are calculated per-square-foot for Commercial use ($0.454/sq ft Fire + $0.022/sq ft Police + $0.968/sq ft Streets; $0.00/sq ft Parks), versus flat per-unit fees for Single Family ($2,092/$1,047/$104/$4,492) and Multi-Family ($1,616/$809/$80/$3,471) — per the City's Permit, Impact & Water Fees schedule (ketchumidaho.gov/DocumentCenter/View/355, table 'DEVELOPMENT IMPACT FEES'). The Building Permit fee valuation table and the 65%/70%/70% Plan Check Fee stack, however, are identical across residential and commercial — there is no separate commercial permit-fee or plan-check-fee schedule.
- The City's website moved from ketchumidaho.org to ketchumidaho.gov (CivicPlus platform). Old ketchumidaho.org links now 301-redirect to the new domain's homepage rather than to the page you asked for, so go to the.gov equivalents directly: Building Services at ketchumidaho.gov/223/Building-Services, Permits at ketchumidaho.gov/229/Permits, the fee schedule PDF at ketchumidaho.gov/DocumentCenter/View/355, and the February 2026 permit-changes PDF at ketchumidaho.gov/DocumentCenter/View/354. The content on all four matches the earlier.org versions — only the hosting domain changed.
