Commercial Building Permit (New Construction, Additions, Remodels & Tenant Improvements)
VerifiedCovers 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.

Requirements
- A building permit is required for new non-residential construction, commercial additions, and commercial interior or exterior remodels and tenant-improvement work, submitted through CommunityConnect — the same online platform and Building Permit product used for residential projects
- Non-residential structures are reviewed against the 2018 International Building Code (as amended by the Idaho Building Code Board, with Appendix O), rather than the 2018 IRC used for one- and two-family dwellings, per Ketchum Municipal Code Title 15, Chapter 15.04
- As of February 27, 2026, the City buckets first-review timelines by project type rather than by residential/commercial occupancy: New Construction and Additions fall in the Standard tier (25 calendar days), while Internal Remodel and External Repair & External Remodel projects fall in the Medium tier (15 calendar days) — a commercial project's timeline depends on which category the work falls into
- Design Review is required, in all zoning districts, for building, developing, or substantially altering the exterior of any nonresidential, public/semipublic, or mixed-use building, per the City's Land Development Code Section 16.04.080.B; a separate Preapplication Design Review step is additionally required ahead of that for new non-residential development meeting the size and scale thresholds in Section 16.07.030.C
- Projects within the City's Mountain Overlay District — a mapped hillside and steep-slope overlay, not itself a snow-load or wildfire designation — face additional siting standards and must complete Design Review before a Building Permit, excavation/grading permit, or construction may begin, per Land Development Code Section 16.02.070.D
- Electrical, plumbing, and mechanical/HVAC work on commercial projects is not permitted by the City; those permits are issued directly by the State of Idaho Division of Building Safety/Division of Occupational and Professional Licenses (DOPL)
- 24-hour advance notice is required for City-scheduled inspections; construction activity is limited to 7:30 AM-7:00 PM on weekdays and Saturdays and prohibited on Sundays and holidays, per Ketchum Municipal Code 8.08.050.14
- A Construction Activity Plan (CAP) is required for projects in the Community Core/downtown; a CAP Affidavit may substitute for eligible, less complex project types outside the Community Core
Required documents
- RequiredBuilding Permit Application (CommunityConnect)Submitted online through the same CommunityConnect platform and general application flow used for residential permits; no separate commercial or tenant-improvement-specific application form is published
- RequiredConstruction DrawingsComplete plan set — site plan, floor plans, elevations, sections, and structural details — demonstrating compliance with the 2018 IBC/IECC as locally amended; where the Building Official determines special inspections apply, results are uploaded to the permit record in CommunityConnect
- OptionalDesign Review ApplicationRequired ahead of, or alongside, the Building Permit for qualifying nonresidential, public/semipublic, or mixed-use exterior work, per Land Development Code Section 16.04.080; reviewed administratively by Planning staff for minor items or by the Planning and Zoning Commission for larger projects

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.
