Inspection process

  1. 1

    Building Official Inspection(s)

    Town Code Chapter 7 vests all building, plumbing, electrical, and other inspection authority in the Town Manager's office (or authorized deputies); the Town's public-facing materials do not break inspections into a named sequence (e.g., footing/framing/final) the way larger AZ cities do — inspections are scheduled directly with the Building Official as work progresses

Tips

  • Duncan's adopted building code is the 2006 IBC per its own town code text (Article 7-1, Rev. 6/06) — this is over a decade behind the current ICC cycle used by larger Arizona cities, and no later code-update ordinance was found published superseding it.
  • The Town of Duncan publishes no review-timeframe figure of any kind — no administrative completeness, substantive review, or overall figure — on its Building Permits & Fees page, in Town Code Chapter 7, on its Notices page, or in any archived capture of duncanaz.us. A.R.S. § 9-835 requires municipalities to establish and publish their own time frames per license type, but supplies no default number, so there is nothing to fall back on. Call Town Hall at 928-359-2791 (Mon-Thu, 8:00 a.m.-5:30 p.m.) for a project-specific estimate.
  • The current fee schedule PDF linked from the Town's live site is header-labeled 'PROPOSED' with no visible resolution number — there is no separately published 'final/adopted' fee schedule distinct from this proposed version currently linked on the Town's site, so it is used here as the best-available authoritative fee source.
  • There is no online permitting portal, application-tracking system, or published email intake address for building permits — applications must be submitted in person or by mail to Town Hall.
