Tips

  • The Floodplain Board for enforcement purposes is either the Flood Control District of Greenlee County or the Duncan Town Council, depending on which body is engaged in enforcement at a given time — this is a joint/shared administrative structure rather than Duncan acting entirely independently of the county on floodplain matters specifically (distinct from the Town's fully independent building-code program).
  • No distinct dollar fee for the Floodplain Permit (NFIP) itself was found on the Town's published fee schedule — only a general non-refundable fee line on the combined permit form. Confirm the exact amount directly with Town Hall.
  • As with all Duncan permit types, no review-timeframe figure is published for floodplain development permit review.

Duncan, 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 (A.R.S. Title 9 for municipalities). The Town of Duncan is a small incorporated town that runs its own building-permit program directly out of Town Hall (the Town Manager's office functions as Building Official) rather than deferring to Greenlee County; this is confirmed by the Town's own Building Permits & Fees page, its Chapter 7 (Building) town code chapter, its Schedule of Fees and Charges, and its paper 'Application for Building Permit and Inspection' form, all of which are Duncan's own documents (not county documents).
