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 as of 7/1/2026 per Utah Code § 15A-2-103(1)(a); supersedes the 2021 edition previously used in Farmington City's design criteria (Residential Building Permit Application Packet, H. Gordon, rev. 4.24.2020, which had not been updated as of 2026-07-16)
• 2021 International Residential Code (IRC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(b) did not change this edition in the 7/1/2026 amendment. Farmington City design criteria (rev. 4.24.2020) and the Reroof & Roof Repair Policy (eff. July 1, 2024) are consistent with this
• Appendix AQ of the 2021 IRC — statewide per Utah Code § 15A-2-103(1)(c); not separately itemized in Farmington's own published materials, added here per statute
• 2024 International Existing Building Code (IEBC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(i); supersedes the 2021 edition cited in Farmington's Reroof & Roof Repair Policy (eff. July 1, 2024), Sections 705 and 706, which had not been updated as of 2026-07-16
• 2021 International Property Maintenance Code (IPMC) — cited in Reroof & Roof Repair Policy (eff. July 1, 2024), Sections 304.1, 304.7, 507; the IPMC is NOT among the codes adopted by Utah Code § 15A-2-103 (property-maintenance code, not a construction code), so no statewide edition change applies here — left as published by the City
• 2024 International Mechanical Code (IMC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(e); supersedes the 2021 edition previously used in Farmington's design criteria (rev. 4.24.2020, not updated as of 2026-07-16)
• 2024 International Plumbing Code (IPC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(d); supersedes the 2021 edition previously used in Farmington's design criteria (rev. 4.24.2020, not updated as of 2026-07-16)
• 2024 International Fuel Gas Code (IFGC) — statewide per Utah Code § 15A-2-103(1)(f); not separately itemized in Farmington's own published design-criteria packet (rev. 4.24.2020), added here per statute since the City's own materials omit it
• 2024 International Energy Conservation Code (IECC), single unsplit statewide edition — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(h); supersedes the 2021 edition previously used in Farmington's design criteria (rev. 4.24.2020, not updated as of 2026-07-16)
• 2023 National Electrical Code (NEC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(g) did not change this edition in the 7/1/2026 amendment. Farmington City design criteria (rev. 4.24.2020) already correctly reflects 2023
• NOTE (2026-07-16 re-verification): The Utah Code § 15A-2-103 version effective 7/1/2026 (superseded 1/1/2027) took effect 15 days before this re-verification. IBC/IPC/IMC/IFGC/IECC/IEBC are now 2024 statewide; IRC (2021) and NEC (2023) did NOT change. Farmington City's own published design-criteria packet (Residential Building Permit Application Packet, rev. 4.24.2020) and Reroof & Roof Repair Policy (eff. July 1, 2024) still reference 2021 editions for IBC/IEBC and had not been updated to reflect the 7/1/2026 transition as of this re-verification; this file now states the governing statutory code (2024 editions) as current per Utah's statewide-mandatory code regime (Utah Code § 15A-1-204), with the City's un-updated 2021 references preserved above as historical/local-document context. The Utah Code § 15A-2-103 citation in the sources array below has been updated to the current in-force version link

Permit types & fees

• Residential Building Permit

  Required for new residential construction, additions, structural alterations, conversions, and basement finishes in Farmington City, governed by the 2024 IBC / 2021 IRC design criteria (2024 IBC current per Utah Code § 15A-2-103(1)(a) effective 7/1/2026; IRC remains 2021 per § 15A-2-103(1)(b)). All permits require two engineer-stamped plan sets and three site plan copies. Farmington's Consolidated Fee Schedule (as adopted 2026-05-19) and Residential Building Permit Application Packet list electrical work as a standard component of the valuation-based building permit (the packet's submittal checklist references 'Electrical components' as part of the general plan set); no distinct EV charger/EVSE fee line item or permit category was found as of 2026-07-19.

• Roofing Permit (Reroof / Roof Recover)

  Required for residential re-roof or roof recover in Farmington City, governed by the Reroof & Roof Repair Policy (effective July 1, 2024), which cites 2021 IBC/IEBC/IRC; IBC and IEBC are now 2024 statewide per Utah Code § 15A-2-103(1)(a)/(i) effective 7/1/2026 (the City policy document itself has not been updated), while IRC remains 2021 per § 15A-2-103(1)(b). Minor repairs under specified thresholds do not require a permit.

  →

• Demolition Permit

  Required for partial or complete demolition of a structure in Farmington City. Requires Historic Preservation Commission review, utility disconnection confirmation, and coordination with Utah Division of Air Quality (asbestos) and Davis County Environmental Health before the permit is finalized.

  →

• Commercial Building Permit

  Required for new commercial building construction in Farmington City, governed by the 2024 IBC (Utah Code § 15A-2-103(1)(a), effective 2026-07-01, superseding the 2021 edition previously used in the City's design criteria). The building permit fee is valuation-based (1997 UBC Table No. 1-A, same table used for residential), with valuation derived from the City's own per-square-foot Building Valuation Data table by occupancy group and construction type; commercial plan check is a flat 65% of the building fee, versus 40% for residential — and shell-only buildings get a 20% valuation deduction.

  →

• Commercial Tenant Improvement / Tenant Finish Permit

  Required for interior tenant-finish and remodel work within an existing commercial building in Farmington City. Farmington's Consolidated Fee Schedule does not publish a separate, discounted fee table for tenant improvement/tenant finish work — the same valuation-based Building Permit Fee formula, the 65% commercial Plan Check Fee, and the $250 commercial Plan Review Deposit apply as for new commercial construction, with valuation computed from the applicable occupancy group's per-square-foot rate in the Building Valuation Data table.

  →

• Solar Panel (PV) Permit

  Required for residential and commercial rooftop solar photovoltaic installations in Farmington City. Farmington's Building Applications and Forms page lists dedicated solar documents (Solar Building Permit Application, Solar Checklist, Commercial Solar, Residential Solar Micro Inverters, Residential Solar String or Central Inverters) separate from its general permit packets, and the Consolidated Fee Schedule carries a distinct 'Solar (Flat Rate)' line item of $378.01 — a genuinely distinct solar-specific fee and technical plan-review checklist, not folded into a generic building-permit valuation.

  →

• Sign Permit

  Required to erect, construct, reconstruct, enlarge, locate, or alter any sign within Farmington City under City Code Title 15 (Sign Regulations), Section 15-2-040. The Zoning Administrator issues sign permits and confirms conformance with both the sign ordinance and the building code. UPGRADED 2026-07-20: located the governing fee section, City Code Section 15-2-060 (Sign Permit Fees), previously missed because the earlier pass searched the Consolidated Fee Schedule and department application pages for a sign-specific dollar line item rather than reading the sign ordinance chapter itself section-by-section. Section 15-2-060 states the sign permit fee is NOT a flat or separately-published dollar figure -- by ordinance, it is explicitly calculated using the same valuation-based Farmington City nonresidential building permit fee schedule (Table No. 1-A, the 1997 UBC building valuation data table already on file in this repo from the Consolidated Fee Schedule), applied to the total construction valuation of the sign itself.

• Certificate of Occupancy (Change of Use / Occupancy)

  Farmington City Code requires a Certificate of Occupancy signed by BOTH the Zoning Administrator and the Building Official before any land or building may be changed in use or occupancy -- this applies even when no structural alteration is involved, not only at the end of new construction. Per City Code section 11-4-050.C (Duties of the Zoning Administrator): 'No land shall be changed in use or occupancy and no building shall be changed in use or structurally altered until a certificate of occupancy shall have been issued by both the zoning administrator and the building official,' and 'a certificate of occupancy shall be required for the purpose of maintaining, renewing, changing or extending a nonconforming use.' Separately, City Code section 11-8-090 requires that a building permit for any building/structure needing a Conditional Use Permit cannot be issued until the Planning Commission approves the conditional use permit -- a related, but distinct, requirement about building permits rather than certificates of occupancy specifically (11-8-090's text does not itself use the word 'certificate'). No fee line item labeled specifically 'Certificate of Occupancy' or 'Change of Use' was found in the city's Consolidated Fee Schedule (adopted 2026-05-19); the closest related published fees are the Land Use Related Fees for Administrative Determination and Conditional Use Application described below, which apply only when the new use requires a zoning classification determination or falls under the nonconforming-use/conditional-use provisions. Re-chased 2026-07-20: located and reviewed Farmington City Code Title 10, Chapter 5 ('Certificates') in full -- Section 10-5-030 (Issuance of Certificate: the Building Official issues a CO after final inspection finds no code violations, with Community Development Director approval), Section 10-5-040 (Notice of Disapproval), and Section 10-5-050 (Temporary Certificates: allows a temporary CO before full project completion, secured by a bond of at least $5,000, with completion required within 30 days, extendable once up to 90 days). Also reviewed Section 12-2-047 (Certificates of Occupancy, Title 12 Subdivision Regulations), which is a DIFFERENT, narrower CO trigger -- it blocks occupancy of any structure within a subdivision until required subdivision infrastructure (street surfacing, street signs, house numbers, utilities) is complete; it does not govern a standalone change-of-use CO for an existing building. None of these newly-reviewed sections states a dollar fee or a numeric review-timeline for a standard or change-of-use Certificate of Occupancy -- this is now confirmed as a genuine, thorough gap in Farmington's own published code and fee schedule, not a retrieval failure. UPGRADED 2026-07-20: read the Consolidated Fee Schedule's full Section C (Building Permit Application and Related Fees) directly via page-image rendering (pages 8 and 11 of the 28-page PDF), which the earlier pass had only sampled for A/B-series Land Use fees rather than reading Section C's complete line-item list end to end. This surfaced two governing fee mechanisms previously missed: (1) Section C5, a genuine, itemized 'Temporary Occupancy Application Fee' of $50.00 (plus the already-documented $5,000 minimum bond under City Code 10-5-050) for a Temporary Certificate of Occupancy; and (2) Table No. 1-A (the same 1997 UBC valuation table used for the base Building Permit Fee), whose item 3 is an explicit catch-all: 'Inspections for which no fee is specifically indicated ... Minimum Charge - one-half hour, $55.55/hr' -- the governing mechanism for a pure change-of-use Certificate of Occupancy inspection that is not otherwise tied to a building permit (since no CO-specific line item exists, this catch-all is what the fee schedule's own structure directs such a case to).

• EV Charger / EVSE Permit

  Farmington City does not publish a separate EV-charger/EVSE permit or fee. The city's Consolidated Fee Schedule (adopted 2026-05-19), Section C ('Building Permit Application & Related Fees'), prices building-permit work via Table No. 1-A, a valuation-based schedule derived from the 1997 Uniform Building Code, with no distinct Electrical, Mechanical, or Plumbing sub-fee and no EV-specific line item found. EV charger installation is therefore handled as standard electrical work under this same valuation-based Building Permit; no EV-specific dollar figure is asserted here.

• Fire Sprinkler System Permit

  Required for new or modified automatic fire sprinkler system installation in Farmington City, administered directly by the Farmington City Fire Department (Fire Marshal James Weston) rather than the Building Department. Farmington's Consolidated Fee Schedule (adopted 2026-05-19) publishes a genuinely distinct fire sprinkler permit fee under Section G4 'Fire Permit Fees,' tiered by protected floor area and bundling three inspections (flow, hydro, final) into the base fee -- verified directly by rendering the fee-schedule PDF to page images (Section G4, page 26 of 28), since pdftotext extraction misorders this table's columns. The Fire Department's own Commercial Plan Review Guide lists NFPA 13 (Standard for the Installation of Sprinkler Systems) and NFPA 13R (low-rise residential occupancies) as the governing installation standards, applied together with the 2021 International Fire Code and the Utah State 2021 Amended Fire Code.

  →

• Fire Alarm System Permit

  Required for new or modified fire alarm system installation in Farmington City, administered directly by the Farmington City Fire Department (Fire Marshal James Weston). Farmington's Consolidated Fee Schedule (adopted 2026-05-19) publishes a genuinely distinct fire alarm plan review fee under Section G3 'Fire Inspection Fees' -- 'Fire Alarm System Installation Plan Review - Alarm Design Approval' and a separate 'Fire Alarm System Plan Re-Review - Alarm Plan Recheck' -- verified directly by rendering the fee-schedule PDF to page images (page 25 of 28). NOTE: the schedule's separate Section G2 'Fire Alarm Fees' ($500 for a 3rd false fire alarm within 365 days, +$100 per additional false alarm in the same rolling period) is a false-alarm penalty schedule, NOT a permit or installation fee, and is not conflated with this entry. Design and installation is governed by NFPA 72 (National Fire Alarm Code) per the Fire Department's own Commercial Plan Review Guide, applied together with the 2021 International Fire Code and the Utah State 2021 Amended Fire Code.
