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

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.

Change of Use Permit
VerifiedRequired 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).

Requirements
- 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))
