Nogales, Arizona has adopted: Arizona has NO statewide mandatory building code floor for general construction — code adoption is a per-city/county authority under state enabling statutes (e.g., A.R.S. Title 9 for municipalities). The City of Nogales independently adopts and administers its own construction codes through its Community Development Department (Planning & Building) and does not defer building permitting to Santa Cruz County.

A narrow no-permit exemption applies where total added square footage is 120 sq ft or less AND the work involves no electric, plumbing, or gas installation/movement/extension/curtailment and does not otherwise violate the Code (Sec. 3.103.d.2).

The Development Code's own Fee Schedule section (Article 3, Sec. 3.113) separately states fees are adopted 'by reference under separate City document,' consistent with the Sec. 5-26 mechanism rather than contradicting it. Plan review fee is 25% of the Building Permit Fee where project valuation is $100,000 or less, and 65% where valuation is $100,001 or more; valuation of garages, porches, canopies, and storage rooms is calculated at $14 per square foot — both figures confirmed via the City's own 'Building Permit Application Requirements' page (Wayback-archived 2016-12-15; the live current page no longer republishes these figures, so they are flagged for reconfirmation, not treated as stale-and-wrong). The exact dollar-bracket IRC Appendix L valuation table itself could not be independently reproduced against ICC's source as of this review (codes.iccsafe.org is a JS-rendered application that blocks automated/scripted access) — a genuine access gap, not an unpublished-fee gap.
