Syracuse, Utah has adopted: 2024 International Building Code (IBC) — Utah Code § 15A-2-103(1)(a); CURRENT as of 7/1/2026 (confirmed by direct fetch of the live statute 2026-07-16). Supersedes the 2021 IBC, which governed through 6/30/2026. Matches Syracuse's own Building Department page (live-checked via browser 2026-07-16), which lists '2024 IBC' among its currently-adopted codes.; 2021 International Residential Code (IRC) — Utah Code § 15A-2-103(1)(b); UNCHANGED by the 7/1/2026 code cycle (confirmed by direct statute fetch 2026-07-16). NOTE (2026-07-16 city-page discrepancy): Syracuse's own Building Department page (syracuseut.gov/160/Building), live-checked via browser 2026-07-16, states verbatim: 'Syracuse City has adopted minimum design and construction requirements found in the 2024 IBC, IPC, IMC and IRC, as well as the 2023 NEC (Please note, starting July 1, 2026, the state of Utah will be adopting the 2024 International Building Codes, IBC, IPC, IMC, IFC, IFGC, IEBC, and IECC, while the International Residential Code (IRC) will remain 2024, and the National Electrical Code (NEC) will remain 2023).' The city's own page appears to have an error here, listing IRC as 2024 both currently and going forward. Utah is a statewide-mandatory-code state — Utah Code § 15A-1-204 requires the state and every political subdivision to follow the State Construction Code, and a municipality cannot unilaterally adopt a different IRC edition than the state. This JSON follows the statute (2021 IRC, confirmed directly against the live Utah Code) rather than propagating the city page's apparent error; the discrepancy is recorded here rather than silently corrected on the city's behalf.; 2024 International Plumbing Code (IPC) — Utah Code § 15A-2-103(1)(d); CURRENT as of 7/1/2026 (confirmed by direct statute fetch 2026-07-16). Supersedes the 2021 IPC, which governed through 6/30/2026. Matches Syracuse's own Building Department page.; 2024 International Mechanical Code (IMC) — Utah Code § 15A-2-103(1)(e); CURRENT as of 7/1/2026 (confirmed by direct statute fetch 2026-07-16). Supersedes the 2021 IMC, which governed through 6/30/2026. Matches Syracuse's own Building Department page.; 2024 International Fuel Gas Code (IFGC) — Utah Code § 15A-2-103(1)(f); CURRENT as of 7/1/2026 (confirmed by direct statute fetch 2026-07-16). Supersedes the 2021 IFGC, which governed through 6/30/2026.; 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); UNCHANGED by the 7/1/2026 code cycle. Confirmed live on Syracuse's Building Department page (re-fetched 2026-07-16: '...as well as the 2023 NEC').; 2024 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h); CURRENT as of 7/1/2026 (confirmed by direct statute fetch 2026-07-16). ONE statewide edition — no residential/commercial split. Supersedes the 2021 IECC, which governed through 6/30/2026.; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); CURRENT as of 7/1/2026 (confirmed by direct statute fetch 2026-07-16). Supersedes the 2021 IEBC, which governed through 6/30/2026.; NOTE (2026-07-16 corpus-staleness fix, including correction of a known IFC error): A prior version of this file correctly anticipated that '2024 International Building Codes' would take effect 7/1/2026, but the codesAdopted entries above had not been flipped to reflect that the date has now passed — IBC/IPC/IMC were still incorrectly stated as '2021 ... currently in effect.' That has been corrected above (IFGC and IEBC entries have also been added, since the statute adopts both). Separately, the prior version's forecast NOTE listed IFC among the codes 'taking effect' 7/1/2026 — that was WRONG and has been removed here: Utah Code § 15A-2-103 contains NO International Fire Code subsection at all and does not adopt any IFC edition, in any year. (Syracuse's own Building Department page does independently mention IFC in its own forecast language, quoted above — that is the city's own text, not something §15A-2-103 adopts, so no IFC entry appears in this codesAdopted array.); Syracuse Municipal Code Chapter 9.15 (Construction Codes, §§ 9.15.010-9.15.070) codifies adoption by reference of the building code, Uniform Plumbing Code, National Electrical Code, and Uniform Mechanical Code 'as published by' the respective national code bodies 'and currently adopted by the state of Utah,' with successive state amendments/editions incorporated automatically upon their Utah State statutory effective date — consistent with the statewide framework under Utah Code Title 15A. Confirmed by direct browser fetch of the live codepublishing.com page (2026-07-16); the site returns HTTP 403 to curl/plain fetch (Cloudflare WAF challenge) but renders normally in a browser. The live chapter also includes § 9.15.070, Adoption of the 2006 Edition of the Utah Wildland Urban Interface Code (Ord. 25-42 § 1), not previously captured in this file.; Syracuse Municipal Code § 9.15.050 adopts by reference the ICC's Building Valuation Data for determining new-construction valuation, consistent with the city's Consolidated Fee Schedule building-value permit-fee tiers.. Local amendments apply — see the Syracuse overview page for the full list.

Per Syracuse Municipal Code § 10.30.020, a recorded owner-occupancy Deed Restriction must be completed, notarized, and recorded at the Davis County Recorder's Office before the building permit for the ADU can be signed off. The property owner must reside on the premises in either the principal or accessory dwelling.
