Change of Use Permit in Millcreek, Utah

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).

When you need this permit

  • Administrative tier: required whenever an existing developed property changes from one use classification established in MKZ Title 18 to another use classification also established in that Title, where the new use is a permitted use in the applicable zone (MKZ 18.15.030(C)(2))
  • Heavier tier: a Conditional Use Permit is required instead, per MKZ 18.15.030(C)(1), when the new use classification is established in Title 18 as a conditional use rather than a permitted use — this follows the Conditional Use Permit procedure at MKZ 18.15.030(A), including a Planning Commission public hearing, and (where there is property development, redevelopment, construction, reconstruction, or alteration of a building/structure) a Site Plan Approval under MKZ 18.15.030(B)
  • The new use must be permitted (or approved as conditional) in the governing zoning district and comply with all applicable development standards — landscaping, parking and mobility standards, minimum driveway/roadway widths, and any dedication or public improvement requirements (MKZ 18.15.030(C)(4))

    Tips

    • Millcreek's zoning code (MKZ 18.15.030(C)) calls the administrative-tier application a 'Change of Use Permit,' decided by the Planning Director with no public hearing — but the Consolidated Fee Schedule still lists its $110 fee under the older label 'Tenant Change' (Item 128, pre-recodification code 19-02-130).
    • If the new use is classified as a conditional use rather than a permitted use in that zone, you need a Conditional Use Permit instead (MKZ 18.15.030(A)) — a Planning Commission public hearing process billed at $1,200 (Item 138) rather than the $110 administrative fee.
    • The 15-business-day planning staff review period (before scheduling the first public hearing) applies to the Conditional Use Permit tier; Millcreek's Planning Applications page does not publish a specific day-count for the administrative-tier Change of Use Permit.
    • Use the official Change of Use Application Checklist (millcreekut.gov/DocumentCenter/View/5475/Change-of-Use-Checklist) to confirm which property survey and site plan items apply to your project.
    • This is a Planning & Zoning Department application, separate from — and in addition to — any Building Department permit (e.g., Commercial Tenant Improvement Permit) needed for physical construction associated with the new use.

    Frequently asked questions

    Only if the new use is classified as a conditional use in that zoning district. If the new use is itself a permitted use, Millcreek's Planning Director decides the Change of Use Permit administratively under MKZ 18.15.030(C), with no public hearing required. If the new use is a conditional use, it instead goes through the Conditional Use Permit process (MKZ 18.15.030(A)), which requires a Planning Commission public hearing with mailed notice to property owners within 300 feet.

    It depends on the tier. The administrative Change of Use Permit (Planning Director decision, no public hearing) costs $110.00, listed in the Consolidated Fee Schedule as 'Tenant Change' (Item 128, pre-recodification code 19-02-130). If the new use is classified as a conditional use rather than a permitted use in that zone, a Conditional Use Permit is required instead, at $1,200.00 (Item 138, 'Conditional Use – Change of Use and No New Development,' includes Planning Commission site plan review).

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. Local amendments apply — see the Millcreek overview page for the full list.
