Codes 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 Town of Dewey-Humboldt (incorporated 2004 from the merger of the unincorporated communities of Dewey and Humboldt) runs its own independent Community Development Department / Building Safety Division and independently adopts and administers its own construction codes under Chapter 150 (Building Codes) of the Dewey-Humboldt Code of Ordinances; it does NOT contract the building-permit function to Yavapai County.

Permit types & fees

Building Permit (New Construction, incl. Single-Family Residence, ADU, Garage/Carport, Room Addition, Manufactured Home)

Verified

Dewey-Humboldt does not split new residential construction into narrowly separate permit types the way some larger cities do — a single Building Permit Application covers new single-family residences, accessory dwelling units, garages, carports, decks, patio covers, room additions, remodels, cell towers, swimming pools, and retaining walls, reviewed against the 2018 IBC/IRC and Town amendments. A separate, similarly-formatted Manufactured Home Permit application applies specifically to manufactured/mobile home placement.

Over-the-Counter (OTC) Permit — Electrical, Plumbing, Mechanical, Demolition

Verified

Dewey-Humboldt does not issue separate electrical, plumbing, mechanical, or demolition permit applications — all four are filed under a single 'Over-the-Counter (OTC) Permit' application/checklist, distinct from the full Residential Building Permit track. The OTC application itself lists 'Demo / Plumbing / Electric / Mechanical / Other' as checkable permit-type boxes on one form.

Verified 2026-07-06 · Source

Requirements

OTC Permit covers: demolition, plumbing work, electrical work, and mechanical (HVAC) work — each selected via checkbox on the same application form
Governed by the applicable adopted code chapter (Electrical Code § 150.07 referencing the NEC as adopted by the Town; Plumbing Code § 150.04; Mechanical Code § 150.05; Fuel Gas provisions within the adopted IRC Chapter 24 as amended)
For projects not exempt under A.R.S. § 32-1121, the contractor must hold a current, valid Arizona ROC license
Septic permit prerequisite (Yavapai County) applies only where the scope of work is connected to septic-relevant plumbing; the OTC checklist does not universally require it the way the full Building/Manufactured Home Permit checklist does
Submittal checklist for OTC ('Elec, Plumb, Mech') requires: signed permit application, 1 Plot Plan (8.5"x11"), and a deposit — full construction plan sets, truss calcs, and site plans are NOT required for this track (those apply only to Residential Building, Manufactured Home, and Solar/Grading permits per the Town's own checklist matrix)

Solar Permit

Verified

Required for residential and other solar photovoltaic installations in Dewey-Humboldt, using a dedicated Solar Permit Application distinct from the general Building Permit and OTC forms.

Requirements

Solar Permit Application distinguishes Residential / Other / Labor Only project types, each with its own valuation entry
Governed by the National Electrical Code as adopted by the Town (§ 150.07) and the 2018 IBC/IRC structural provisions for roof-mounted or ground-mounted arrays
A copy of the county septic approval must be attached per the printed form instruction (NOTE: this requirement is printed on the Solar Permit Application template itself, even though septic relevance to a solar-only project may not always apply — likely a shared template carried over from the Building Permit form; confirm applicability with Building Safety for solar-only, no-septic-impact projects)
For projects not exempt under A.R.S. § 32-1121, the contractor must hold a current, valid Arizona ROC license
Submittal checklist ('Solar Permit' column) requires: signed application, 2 sets of full construction plans, 1 Plot Plan (8.5"x11"), Affidavit of Site Soil/Soils Report, Directions to Site (possibly), and a deposit — no separate site plan or truss calculations required

Grading Permit

Verified

Required for site excavation, fill, and grading work in Dewey-Humboldt under the Town's own locally authored Grading Ordinance Code (§ 150.08) rather than an ICC model code, often paired with a Residential Building Permit for new construction involving significant site work.
