Tips

  • Davis County uses a single building permit application for all construction types including electrical, plumbing, mechanical, and structural — submit one application through daviscounty.portal.iworq.net covering the full scope of work.
  • Inspections are conducted by Shums Coda Associates. Schedule at least 24 hours in advance via email (ut@shumscoda.com) or phone (800-286-0374).
  • If Davis County cannot complete a requested inspection within 3 business days, you may use a third-party inspector (Farmington City 801-451-2383, Kaysville City 801-544-1363, or Syracuse City 801-825-1477) — but you must notify Davis County before doing so (Utah Code § 15A-1-105).
  • Valuation is the total combined cost of all work: foundation, structural and non-structural components, electrical, plumbing, mechanical, and interior finish materials including labor. Davis County uses the February 2021 ICC Building Valuation Data as a reference.
  • A 2.5% credit card processing fee applies. Pay by check (mailed to 61 S Main St, Farmington UT 84025) or call (801) 451-3278 to avoid the surcharge.
  • The statewide 2024 I-codes take effect July 1, 2026 — plans accepted for review before that date are reviewed under the codes in effect on submission date.
