Codes adopted
Utah adopts construction codes statewide under Utah Code Title 15A (State Construction and Fire Codes Act), enforced by every jurisdiction. Chapter 4 of Title 15A codifies Legislature-enacted amendments for specific named jurisdictions (e.g., Park City, Salt Lake City, Sandy City) as part of the state construction code. Through June 30, 2026, the editions in force under Utah Code § 15A-2-103 are the 2021 IBC (with Appendices C and J), 2021 IRC, 2021 IPC, 2021 IMC, 2021 IFGC, 2021 IECC, 2021 IEBC, and 2021 ISPSC (residential provisions), together with the 2023 NEC. Effective July 1, 2026, § 15A-2-103 adopts the 2024 editions of the IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC; the IRC remains the 2021 edition and the NEC remains the 2023 edition. Note: residential energy requirements are modified by statewide amendments, and several Utah jurisdictions document their residential energy provisions at the 2015 IECC level rather than the adopted IECC year — confirm the applicable residential energy code with your local jurisdiction. Always confirm the edition in force with your local jurisdiction.
- 2024 International Building Code (IBC), including Appendices C and J — current statewide-adopted edition per Utah Code § 15A-2-103(1)(a), in force since July 1, 2026 (superseded the 2021 IBC).
- 2021 International Residential Code (IRC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(b), unchanged by the July 1, 2026 code cycle flip; Summit County's official 'Effective 7/1/2026 IRC Project Design Criteria' table (R301.2(1)) confirms structures governed by the IRC are designed to the 2021 IRC baseline per current adoption.
- 2024 International Plumbing Code (IPC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(d), in force since July 1, 2026 (superseded the 2021 IPC).
- 2024 International Mechanical Code (IMC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(e), in force since July 1, 2026 (superseded the 2021 IMC).
- 2024 International Fuel Gas Code (IFGC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(f), in force since July 1, 2026 (superseded the 2021 IFGC).
- 2024 International Energy Conservation Code (IECC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(h), in force since July 1, 2026 (superseded the 2021 IECC; one edition applies statewide, no separate residential/commercial split).
- Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(n), in force since July 1, 2026 (superseded the 2021 ISPSC); applicable to Summit County pool/hot tub permits (APSP-15/APSP-7 compliance documentation required).
- 2023 National Electrical Code (NEC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(g), unchanged by the July 1, 2026 code cycle flip.
- 2024 International Existing Building Code (IEBC) — current statewide-adopted edition per Utah Code § 15A-2-103(1)(i), in force since July 1, 2026; not separately itemized on Summit County's own published materials, added here as it applies statewide.
- NOTE: The July 1, 2026 statewide code cycle flip (Utah Code § 15A-2-103, amended by Ch. 47, 2026 General Session) is now in effect — the 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and (residential provisions of) ISPSC are the current statewide-adopted codes, while the IRC (2021) and NEC (2023) did not change in this cycle.
Permit types & fees
Residential Building Permit
Required for new single-family dwellings, duplexes, townhouses, manufactured homes, additions with living space, and other IRC-governed residential construction in unincorporated Summit County, including the Snyderville Basin (Silver Creek, Pinebrook, Jeremy Ranch, Summit Park) and the East Side/3-Mile/Henefer-area unincorporated communities. All applications are submitted and reviewed through the EPROCESS360 online portal — no paper or over-the-counter submissions are accepted.
Commercial Building Permit
Required for new commercial building construction in unincorporated Summit County, including the Snyderville Basin (Silver Creek, Pinebrook, Jeremy Ranch, Summit Park) and the East Side/3-Mile/Henefer-area unincorporated communities. Construction and structural plans must be drafted by an architect licensed in the state of Utah. All applications are submitted and reviewed through the EPROCESS360 online portal, per the County's 'New Commercial Checklist' (current as of 6/2026).
Commercial Tenant Improvement / Tenant Finish Permit
Required for tenant improvement (tenant finish) work in existing commercial buildings in unincorporated Summit County — interior build-outs, remodels, and finish work for a new or changing tenant space. Plans for tenant improvements of a finished shell and change-of-use remodels must be designed by an architect licensed in the state of Utah. All applications are submitted and reviewed through the EPROCESS360 online portal, per the County's 'Commercial Remodel/Tenant Improvement Checklist' (current as of 6/2026).
EV Charger / EVSE Permit
Summit County does not publish a distinct EV charger / EVSE permit type or fee line item. Directly read in full (2026-07-20, rendered page-by-page as images since the source PDF is scanned/non-machine-readable) the complete 'Summit County Building Department Fee Schedule' section of the County-Wide Fee Schedule (Ordinance 834-P, amended May 2026, effective 6/2026) — it lists a general Building Permit Fee (0.0075, i.e. 3/4 of 1%, of construction valuation, $100 minimum, both commercial and residential), a separate 'Alternative Energy Permits' category explicitly limited to 'solar, hot water, photovoltaic, geo-thermal, and wind generated power' ($700 photovoltaic / $500 geo-thermal / $250 solar hot water / $250 wind generator), and separate flat $100 fees for 'Electrical utility meter upgrade or replacement,' 'Mechanical utility meter upgrade or replacement,' and 'Plumbing utility meter upgrade or replacement.' No 'EV,' 'electric vehicle,' or 'charging station' line item appears anywhere in this fee schedule. Because EV/EVSE installation is not one of the enumerated Alternative Energy Permit categories and is not a utility-meter upgrade, it is billed as ordinary electrical work under the general Building Permit Fee (0.0075 x construction valuation, $100 minimum), the same mechanism used for standard building/electrical/mechanical/plumbing work in unincorporated Summit County.
Fire Sprinkler & Fire Alarm System Permit
Unincorporated Summit County's Community Development/Building Division does not itself operate a fire marshal's office or issue fire sprinkler/alarm permits. Instead, new installation, alteration, or extension of a fire sprinkler system (NFPA 13/13R/13D) or fire alarm system (NFPA 72) is permitted and plan-reviewed directly by whichever independent local fire protection district serves the property's location -- separate from, and in addition to, the County building permit issued through EPROCESS360. This jurisdiction's own commercial-building-permit entry already lists a 'Fire Approval Letter' from the applicable fire district as a required document and a 'Fire District Inspection' as a required step before Certificate of Occupancy; this entry documents that separate fire-district-run process itself. Two districts covering unincorporated Summit County were independently verified with live fee/process data: Park City Fire District (covers the Snyderville Basin west side -- Kimball Junction, Jeremy Ranch, Pinebrook, Trailside, Silver Summit, and similar subdivisions) and North Summit Fire District (covers the Coalville/eastern county area). A third district, South Summit Fire District, also reviews fire sprinkler installations in its own coverage area (the Kamas Valley/eastern county) per NFPA 13-D. Its current live site (southsummitfd.gov) is a JavaScript single-page application whose Permits section submits directly to a Stripe-backed payment API (react-with-backend.onrender.com/api/sprinkler) that calculates a fee dynamically from submitted square footage rather than publishing a static rate, so no current flat or per-square-foot sprinkler fee is publicly readable on the live site. A historical figure was recovered via Wayback Machine from the district's former official domain (ssfd.us, since retired in favor of southsummitfd.gov): a 2023-labeled fee schedule page (last archived with full content 2024-06-07) listed 'Sprinkler/Fire Suppression Fees $250.00*'. This figure is over two years old and cannot be confirmed as still current given the site's redesign to a dynamic calculator -- treat it as historical context only and confirm the actual current amount directly with South Summit Fire District at (435) 783-2375 before relying on it.
Solar Photovoltaic (PV) Installation Permit
Unincorporated Summit County requires a Building Permit for solar PV installations, per the County Building Department's official page: 'Permits are also required for solar PV installations.' Unlike the general residential/commercial Building Permit (which is priced off the ICC Building Valuation Data table and a non-public multiplier), the County's own Building Department Fee Schedule (Ordinance 834-P) prices solar PV under a distinct 'Alternative Energy Permits' category — explicitly described in the ordinance as 'separate from the permits issued for new construction' — with a flat $700 Photovoltaic System fee. Applications are still submitted through the same EPROCESS360 online portal as all other County building permits; no standalone solar-only application form, checklist, or fee schedule document is currently published (the County's historical 'Solar ABCs' expedited-permitting checklist, once posted at DocumentCenter View 272, is now a dead link with no Wayback capture, confirmed by this verification).
Sign Permit
Unincorporated Summit County requires a sign permit before any sign is erected, relocated, or enlarged, administered by the Community Development Department's Planning Division -- a separate process from the Building Division's EPROCESS360 portal used for this file's other permit types. Sign design standards are set at the Title/Chapter level and differ by planning district: the Snyderville Basin (Silver Creek, Pinebrook, Jeremy Ranch, Summit Park, and the resort-adjacent area surrounding Park City) is governed by Snyderville Basin Development Code Section 10-8-2, most recently amended by Ordinance No. 1010 (adopted by the Summit County Council on/around April 22-23, 2026); the East Side/3-Mile/Henefer-area communities are governed by the parallel Eastern Summit County Development Code Section 11-6-4, whose full standards were read directly from the County's own published code PDF on 2026-07-22. The County-Wide Fee Schedule (Ordinance 834-P, as amended, Community Development Department Fee Schedule, item 20) sets a flat fee of $100 per sign, confirmed live 2026-07-22.
Certificate of Occupancy / Change of Use
Unincorporated Summit County does not operate a standalone "change of use" permit separate from its Certificate of Occupancy (C.O.) process. Per Snyderville Basin Development Code Section 10-3-20(J) (Certificates of Occupancy) -- this file's own localAmendments entry already documents Section 10-3-20 as this jurisdiction's countywide Building Permit and Certificate of Occupancy provision -- a Certificate of Occupancy is required "before any structure or premises, or part thereof, hereafter erected, changed, converted, moved, altered or enlarged wholly or in part, may be used or occupied," making a change of use itself one of the events that triggers a required C.O. For commercial tenant spaces specifically, a change of use is also a documented trigger in this file's commercial-tenant-improvement-permit entry (it requires a Site Plan, and a change-of-use remodel must be designed by a Utah-licensed architect), so a genuine change-of-use project in an existing commercial building generally proceeds through that Commercial Tenant Improvement / Tenant Finish permit process (or, for a change of use with no construction work, directly through a standalone C.O. application) rather than through a separately named "change of use permit." This entry documents the County's own Certificate of Occupancy requirements, directly sourced from its "Items needed to receive a Certificate of Occupancy" checklist (updated 11/25, confirmed live 2026-07-22).

County-wide figures: countySlug uses the '-ut' suffix to disambiguate from Colorado's Summit County (Breckenridge/Dillon/Frisco/Silverthorne/Blue River), which already claims the bare 'summit-county' slug in this corpus's data/counties.json — same slug already used by coalville.json and park-city.json. This file covers unincorporated Summit County only (excludes Coalville and Park City, which are separately incorporated and have their own jurisdiction files). Unincorporated Summit County includes the Snyderville Basin (Silver Creek, Pinebrook, Jeremy Ranch, Summit Park, Old Ranch Road — the resort-adjacent area surrounding Park City), plus East Side communities (Kamas Valley area, Wanship, Henefer environs) and 3-Mile Canyon/Henefer collection areas outside city limits.

Tips & gotchas
- Summit County operates its own unincorporated-area building program (Community Development Department, Building Division) for all land outside Coalville and Park City, including the Snyderville Basin resort area (Silver Creek, Pinebrook, Jeremy Ranch, Summit Park, Old Ranch Road) and East Side/3-Mile/Henefer-area communities.
- All permit submissions, reviews, payments, and issuance are handled exclusively through the EPROCESS360 online portal (summit.co.ut.eprocess360.com) — the County does not accept paper plans or perform over-the-counter reviews.
- Building permit fees follow a published flat-rate formula, confirmed 2026-07-23 by direct read of Ordinance 834-P: 0.0075 (3/4 of 1%) of construction valuation, $100 minimum, for both residential and commercial permits (including tenant improvements, based on the submitted Bid Contract cost rather than the ICC BVD table), plus a 65% Plan Review Fee, a $200 (new structures) or $65 (all other permits) Plan Review Deposit, and a 1% Utah State Surcharge. The exact dollar total is still only visible inside EPROCESS360 once plan review completes and the precise construction valuation is assessed, so contact the Building Department directly for a project-specific estimate before budgeting.
- Snyderville Basin (surrounding Park City) and the East Side/Eastern Summit County are Summit County's two separate planning districts, each with its own Planning Commission, General Plan, and (for Snyderville Basin) a dedicated Development Code (Title 10, Chapter 8) — planning/zoning prerequisites can differ by district even though the same County Building Division issues and reviews building permits county-wide.
- Starting January 1, 2025, the County restructured its residential permit 'Scope of Work' classification titles (e.g., 'New Single Family Detached (IRC)', 'Accessory Dwelling Unit (IRC)', 'Addition (Living Space)' vs. 'Addition (Non-Living)', 'Alteration (Interior)' vs. 'Alteration (Exterior)') — selecting the wrong scope or providing insufficient description results in application rejection.
- Design criteria per the County's current 'Effective 7/1/2026' table (confirmed live 2026-07-16, values unchanged from the prior period): Ground Snow Load 115 psf, Wind Design Speed 115 mph, Seismic Design Category D/D1, Frost Line Depth 36 inches, Ice Barrier Underlayment Required.
- A written water-availability confirmation (existing system hookup statement, or private-source water-rights evidence) is required before a dwelling building permit can be issued (Development Code § 10-3-20(C)).
- Inspectors are not assigned until after 4:30 PM the day before the requested inspection date; next-day inspection requests must be submitted by 3:30 PM (or when the day's slots fill, whichever comes first).
- Some remote areas along the Mirror Lake Highway (Manor Lands, Uinta Lands, Wilderness Acres, Monviso, Christmas Meadows, Pine Plateau, and similar) do not receive specific inspection time windows due to travel distance — contact your assigned local inspector directly.
- An approved final inspection does not by itself constitute a Certificate of Occupancy — a C.O. requires sign-off from all applicable departments/agencies (Building, Engineering, Fire, and Water/Sewer or Health Department for septic) and not every permit type results in a C.O.
