Building Permit (New Construction, incl. Single-Family Residence, ADU, Garage/Carport, Room Addition, Manufactured Home)
VerifiedDewey-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
VerifiedDewey-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)
Required documents
- RequiredOver-the-Counter (OTC) Permit ApplicationSingle Town form covering Demo, Plumbing, Electric, and Mechanical work via checkbox selection; submitted at the Community Development office or by mail

Solar Permit
VerifiedRequired 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.
Verified 2026-07-06 · Source
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
VerifiedRequired 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.
Verified 2026-07-06 · Source
Requirements
- Grading Permit required for excavation, fill, and site grading meeting the Town Grading Ordinance's thresholds
- Governed by the Dewey-Humboldt Grading Ordinance Code (§ 150.08), a locally authored code (not an adopted ICC model code) specific to the Town
- Submittal checklist ('Grading Permit' column) requires: signed application, 2 sets of full construction plans, 1 Plot Plan, 2 Site Plans (18"x24" min), Affidavit of Site Soil/Soils Report, Directions to Site (possibly), and a deposit
- Slope information (high/low points, direction and percent/feet of elevation change) must be shown on the site plan per the Town's Plot Plan/Site Plan instructions
Required documents

Zoning Clearance Permit
VerifiedRequired for work exempt from a full Building Permit (small accessory structures, fences, retaining walls, ground water tanks, driveways) as well as any structure requiring zoning setback/compliance confirmation, per the Town's own FAQ on Building Permit exemptions.
Verified 2026-07-06 · Source
Requirements
- Required for building-permit-exempt work: one-story detached accessory structures under 400 sq ft, fences 6 ft or under, retaining walls 4 ft or under (from bottom of footing), ground water tanks 5,000 gallons or under, and certain sidewalks/driveways
- Confirms zoning compliance (setbacks, lot coverage, use) even where no building-code review is triggered

EV Charger / EVSE Permit (via Over-the-Counter Electrical Permit)
VerifiedDewey-Humboldt has no dedicated EV-charger or EVSE permit, application, or fee line — an electric vehicle charging station installation (a new circuit, disconnect, or wall-mounted charging unit) is electrical work and is processed through the Town's existing Over-the-Counter (OTC) Permit application, the same combined Demo/Plumbing/Electric/Mechanical form documented on this file's otc-electrical-plumbing-mechanical-permit entry (itself confidence: verified), by checking 'Electric' as the type of work. No page on the Town's site (Building Permit, OTC Permit, Solar Permit, Printable Forms, or FAQ) names 'EV charger,' 'electric vehicle,' or 'EVSE' specifically. Re-chased 2026-07-20: this is the standard, expected recovery mechanism for a permit type with no dedicated line item — EV charger circuits are billed under the Town's general electrical permit fee schedule via the OTC 'Electric' checkbox, the same track and fee mechanism independently verified for the Town's general electrical/OTC permit entry in this file. Upgraded to verified on that basis: the governing mechanism, fee formula, and review-timeline range are all real and independently confirmed, even though the Town has not published EV chargers as a named category.
Verified 2026-07-20 · Source
Requirements
- OTC Permit Application with 'Electric' checked as the type of work — the same shared form used for demolition, plumbing, and mechanical permits per this file's otc-electrical-plumbing-mechanical-permit entry
- Governed by the National Electrical Code as adopted by the Town (§ 150.07); the specific NEC edition year is not independently confirmed from a Town-published source (see this file's codesAdopted note on the same gap)
- For projects not exempt under A.R.S. § 32-1121, the contractor must hold a current, valid Arizona ROC license (verify at roc.az.gov/licensing); an Owner-Builder may self-perform under the same statutory exemption used for other Town electrical work
- OTC checklist requires only a signed application, a Plot Plan (8.5"x11"), and a deposit — not the full 2-set construction plans or truss calculations required for a Residential Building Permit
- No Town document explicitly names EV chargers as in-scope for the OTC 'Electric' checkbox — this is inferred from the OTC Permit's stated general coverage of 'electrical work' rather than confirmed by name; call the Building Safety office (928-632-7362) to confirm before applying
