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 — currently in effect as of July 1, 2026, superseding the 2021 IBC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(a)); see NOTE below on Millcreek's own page lagging this update
• 2021 International Residential Code (IRC), including Appendix AQ (Tiny Houses) — currently in effect; unchanged by the July 1, 2026 statewide code-edition update (Utah Code § 15A-2-103(1)(b))
• 2024 International Plumbing Code (IPC) — currently in effect as of July 1, 2026, superseding the 2021 IPC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(d))
• 2024 International Mechanical Code (IMC) — currently in effect as of July 1, 2026, superseding the 2021 IMC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(e))
• 2024 International Fuel Gas Code (IFGC) — currently in effect as of July 1, 2026, superseding the 2021 IFGC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(f))
• 2023 National Electrical Code (NEC) — currently in effect; unchanged by the July 1, 2026 statewide code-edition update (Utah Code § 15A-2-103(1)(g)). Millcreek's Building Services page previously referenced a 2020 NEC edition (recorded as of 2026-06-30); the 2023 NEC supersedes it statewide regardless of the page's wording
• 2024 International Energy Conservation Code (IECC) — currently in effect statewide as of July 1, 2026, a single edition with no residential/commercial split under current law (Utah Code § 15A-2-103(1)(h))
• Historical (superseded): prior to July 1, 2026, Millcreek's Building Services page cited a 2015 IECC edition for residential and a separate 2021 IECC edition for commercial — both are now superseded by the single 2024 IECC per § 15A-2-103(1)(h); re-checked live 2026-07-16 and Millcreek's page (millcreekut.gov/165/Building-Services, via its Building Department overview page and 'Adopted Construction Codes' resource) still displayed this superseded 2015/2021 split — city page lags the statute
• 2024 International Existing Building Code (IEBC) — currently in effect as of July 1, 2026, superseding the 2021 IEBC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(i))
• Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — currently in effect as of July 1, 2026, superseding the 2021 ISPSC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(n))
• 2006 International Wildland-Urban Interface Code (IWUIC) — millcreekut.gov/165/Building-Services; applies to Foothills/Canyons Overlay Zone properties
• NOTE (updated 2026-07-16): the July 1, 2026 transition forecast in the prior version of this entry has now occurred — confirmed live against Utah Code § 15A-2-103, current version (effective 7/1/2026, superseded 1/1/2027), read at le.utah.gov/xcode/Title15A/Chapter2/15A-2-S103.html. Millcreek's own Building Department page (millcreekut.gov, live 2026-07-16) still displays a banner reading 'On July 1, 2026, the State of Utah will adopt all 2024 I-Codes with State Amendments. Any Commercial project submitted on or after July 1st will need to be designed to these standards' — forward-looking, present-tense-stale wording that also narrows the transition to Commercial projects only; the statute imposes no residential/commercial distinction for IBC/IPC/IMC/IFGC/IECC/IEBC/ISPSC, so this record treats the full 2024 edition set as governing for all project types as of 2026-07-16, and flags the city page as not yet updated to reflect that the date has passed

Permit types & fees

• Residential Building Permit

  Required for new residential construction, additions, structural alterations, and work requiring plan review in Millcreek. Governed by the 2021 International Residential Code (IRC) for residential construction and the 2024 International Building Code (IBC) for commercial construction, as adopted by Utah Code § 15A-2-103; the 2024 IBC superseded the 2021 IBC on July 1, 2026.

  →

• Electrical Permit

  Required for electrical work in Millcreek including new circuits, panel upgrades, service changes, and new construction wiring. Governed by the 2023 National Electrical Code (NEC) statewide per Utah Code § 15A-2-103(1)(g). EV charger/EVSE installation is electrical work and falls under this general Electrical Permit; the Millcreek FY25 Consolidated Fee Schedule does not publish an EV-specific line item, so a charger install is billed under the standard Electrical Permit Base Fee.

  →

• Plumbing Permit

  Required for plumbing installations, alterations, and repairs in Millcreek including water heaters, re-pipes, and fixture additions. Governed by the 2024 International Plumbing Code (IPC) as adopted by Utah Code § 15A-2-103, effective July 1, 2026 (superseded the 2021 edition).

  →

• Mechanical / HVAC Permit

  Required for heating, ventilation, and air conditioning installations, replacements, and ductwork modifications in Millcreek. Governed by the 2024 International Mechanical Code (IMC) as adopted by Utah Code § 15A-2-103, effective July 1, 2026 (superseded the 2021 edition).

  →

• Roofing Permit

  Required for residential roof replacement (re-roof) in Millcreek. The FY25 fee schedule lists a flat $70 residential re-roof fee, distinct from the standard ICC valuation-based building permit fee.

  →

• Solar Panel Permit

  Required for installation of rooftop or ground-mounted solar photovoltaic (PV) systems in Millcreek. The FY25 fee schedule lists a flat $70 base permit fee plus a $30 per-kW fee and a $100 plan review fee. The 2021 IRC and 2023 NEC govern the installation.

  →

• Water Heater Permit

  Required for water heater installation, replacement, or conversion (tank to tankless) in Millcreek. Processed as a plumbing permit under MKC § 15-16-020. The FY25 fee schedule explicitly lists 'Water Heater' as a covered MEP item under the $70 base fee.

  →

• Demolition Permit

  Required for partial or complete demolition of structures in Millcreek. Permit fee is valuation-based using the ICC Building Valuation Data. DEQ asbestos and lead paint requirements apply per Utah DEQ and federal NESHAP regulations.

  →

• Window and Door Replacement Permit

  Required for replacement of windows and doors (residential, replacement only with no other structural work) in Millcreek. The FY25 fee schedule lists a flat $70 residential window/door replacement-only fee.

  →

• Commercial Building Permit

  Required for new commercial construction in Millcreek, regulated by the 2024 International Building Code (current statewide as of July 1, 2026, per Utah Code § 15A-2-103(1)(a)). Millcreek's own Building Department page carries a banner stating 'Any Commercial project submitted on or after July 1st will need to be designed to these standards' — the 2024 I-Codes. Fees use the same ICC-valuation-based Building Permit table as residential construction (Millcreek FY25 Consolidated Fee Schedule, Item 1, MKC § 15-08-030), with plan review billed at the Commercial rate of 65% of the building permit fee (Item 20) rather than the 40% residential rate (Item 19).

  →

• Commercial Tenant Improvement / Tenant Finish Permit

  Millcreek terms this permit type 'Commercial Alteration' in its own published requirements guide. Required for tenant finish, remodel, and alteration work in existing commercial buildings, regulated by the 2024 IBC (current statewide 2026-07-01) and reviewed under the International Existing Building Code (IEBC) 'Level of Alteration' compliance method. Fees use the same ICC-valuation-based Building Permit table as new commercial construction, billed at the Commercial plan review rate of 65% (MKC § 15-08-030, Item 20).

  →

• Sign Permit

  Required in Millcreek for new or altered signage. The Consolidated Fee Schedule separately lists a $500.00 Site Plan Review fee for Permitted Uses and Signs alongside the $110.00 sign permit fee, suggesting a site-plan-review step may apply in some cases; the flat fee is set by the city's Consolidated Fee Schedule.

  →

• EV Charger / EVSE Permit

  Millcreek does not publish a distinct EV-charger fee line item. Per the Millcreek FY25 Consolidated Fee Schedule (Millcreek Municipal Code § 15-16-020), installing an EV charger (EVSE) is electrical work billed under the city's general Electrical Permit Base Fee.

  →

• Fire Sprinkler System Permit

  Millcreek is served by the Unified Fire Authority (UFA), which acts as the fire code official under International Fire Code (IFC) Sections 104.7.2 and 105.1.1 and issues its own permit for installation or modification of automatic fire sprinkler systems — this permit is issued and administered entirely by UFA, not by the Millcreek Building Department. Plans generally require an independent third-party peer review before UFA's final review and permitting. Neither Millcreek's own FY25 Consolidated Fee Schedule nor UFA's own published Fee Schedule 2025 lists a specific dollar fee for this permit type (both checked in full); when a sprinkler system is installed as part of new construction or a tenant improvement, Millcreek's separate valuation-based Building Permit fee (see the Commercial Building Permit and Commercial Tenant Improvement / Alteration Permit entries) still applies to the overall project.

  →

• Fire Alarm System Permit

  Millcreek is served by the Unified Fire Authority (UFA), which acts as the fire code official under International Fire Code (IFC) Sections 104.7.2 and 105.1.1. Per UFA's own Fire Alarm and Detection System Submittal guide, 'All new commercial fire alarm system installations and existing system additions or modifications require a plan submittal and permit from UFA' — this permit is issued and administered entirely by UFA, not by the Millcreek Building Department. Neither Millcreek's own FY25 Consolidated Fee Schedule nor UFA's own published Fee Schedule 2025 lists a specific dollar fee for this permit type (both checked in full); when a fire alarm system is installed as part of new construction or a tenant improvement, Millcreek's separate valuation-based Building Permit fee (see the Commercial Building Permit and Commercial Tenant Improvement / Alteration Permit entries) still applies to the overall project.

  →

• Change of Use Permit

  Required when a developed property in Millcreek changes from one zoning use classification to another under Millcreek Zoning Code (MKZ) Title 18. Millcreek runs two tiers: an administrative Change of Use Permit (MKZ 18.15.030(C)), decided by the Planning Director with no public hearing, for use changes where the new use is itself a permitted use in that zone; and a Conditional Use Permit (MKZ 18.15.030(A)), decided by the Planning Commission after a public hearing, when the new use is classified in that zone as a conditional use rather than a permitted use. The Millcreek Consolidated Fee Schedule (dated 8/12/2024, predating the City's April 28, 2025 Title 18 recodification) lists these fees under their prior code citations as 'Tenant Change' (19-02-130, $110.00, staff-level) and 'Conditional Use – Change of Use and No New Development' (19-84-030, $1,200.00, Planning Commission-level, includes site plan review).
