Fee schedule

Requirements

• Same Building Permit Application used for residential and commercial ('Other') construction; the applicant checks 'Other' rather than 'Residential' and enters Project Valuation (excluding land) -- confirmed directly from the Town's Building Permit Application PDF
• Governed by the 2018 International Building Code (§ 150.02) and Town amendments, not the 2018 IRC, which the Town's own administrative code limits to detached one- and two-family dwellings and townhouses
• 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)
• The Building Permit Application's printed instruction to 'ATTACH A COPY OF THE COUNTY SEPTIC APPROVAL' appears once on the shared form and is not marked as residential-only; confirm with Building Safety (928-632-7362) whether it applies to a specific commercial parcel, since many commercial sites in the Town's core may already be on public sewer rather than septic
• A final inspection and Certificate of Occupancy (or Use Permit) are required before occupancy -- printed directly on the Town's own 'Detailed Plan Requirements' packet ('FINAL INSPECTION REQUIRED FOR A CERTIFICATE OF OCCUPANCY OR USE PERMIT') and echoed in the Town's FAQ
• Tenant improvement / change-of-occupancy work on an existing commercial building is processed through this same Building Permit Application under 2018 IEBC (§ 150.09) provisions -- no distinct TI permit, application, or fee line exists on the Town's published materials
• If the project involves a new or modified fire sprinkler or fire alarm system, a separate permit from Central Arizona Fire and Medical Authority (CAFMA) is required independently of the Town's own review -- see this file's fire-sprinkler-permit and fire-alarm-permit entries
• Permit becomes invalid 2 years after issuance; work must commence within 180 days and inspections must occur at least every 180 days or the permit becomes null and void (one 180-day extension available at Building Official's discretion) -- same validity language printed on the shared Building Permit Application

Required documents

• RequiredBuilding Permit Application ('Other' checked)The identical Town of Dewey-Humboldt Building Permit Application used for residential projects, with 'Other' checked in the Permit Type field instead of 'Residential'; submitted by mail or in person at 2735 S. Highway 69, Suite 12, Humboldt, AZ 86329 or PO Box 69
• RequiredPlot Plan Sketch and Affidavit (8.5"x11")Town-provided form; must show all structures, dimensions, setbacks, easements, road cuts, and watercourses within 50/100/200 ft as applicable, drawn to scale in black ink

• OptionalApproved Yavapai County Septic PermitRequired if the site is not on public sewer, per the printed instruction on the shared Building Permit Application form; confirm applicability for sewered commercial parcels with Building Safety

• 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)

• 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

Fee schedule

• 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

Required documents

• RequiredOver-the-Counter (OTC) Permit ApplicationSame shared Town form used for Demo, Plumbing, Electric, and Mechanical work; select 'Electric' for an EV charger circuit/unit installation

• Temporary signs (per § 153.130) require a separate temporary sign permit, valid for no more than 6 months, extendable only via a use permit (§ 153.127(F))
• No dedicated downloadable 'Sign Permit Application' PDF was found on the Town's Printable Forms page (dhaz.gov/2166/Printable-Forms) as of this verification — the ordinance itself (§ 153.127(D)) states the application is made 'on forms provided by the town'; contact Community Development (928-632-7362) to obtain the current form, since it is not posted online alongside the Building/OTC/Solar/Zoning Clearance forms

Fee schedule

Requirements

• For a change of use that is allowed by right in the applicable zoning district: submit a Zoning Clearance Application to Community Development; Chapter 153 Appendix A prices this under 'Nonresidential: noncommercial; motels; camps; commercial; industrial; changes of use; includes slabs, paving, walls, fences, sign supports' at $0.125 per sq. ft. under roof, with a $125 minimum permit fee
• For a proposed use that is NOT allowed by right in the applicable zoning district: a discretionary Use Permit (§ 153.091) is required instead, granted at the discretion of the Town Council after a Planning & Zoning Commission hearing and a Council hearing; the Town publishes an A.R.S. § 9-835-style timeframe for this specific track (see reviewTimelineNote) via its 'Use Permit Process Flow Diagram'
• On the building-code side, a change of occupancy classification (as defined by the adopted 2018 International Existing Building Code, § 150.09) triggers Building Official review under IEBC provisions governing repair, alteration, change of occupancy, addition, and relocation of existing buildings -- processed through this file's residential-building-permit or otc-electrical-plumbing-mechanical-permit entry depending on scope of work, not a standalone 'change of use' building permit
• A final inspection and a Certificate of Occupancy are required by the Town before the new use may occupy the space, per the Town's own FAQ ('When can I occupy my new home? A final inspection and a Certificate of Occupancy are required prior to occupancy.'); no separate CO-specific fee line was found in Chapter 150 Appendix A -- CO issuance appears bundled into the standard Building Permit fee mechanism (Yavapai County pass-through + 42% Town administration fee) rather than charged separately
• If the change of use involves a fire-protection system change (e.g., a new commercial occupancy requiring sprinklers or an alarm system), a separate CAFMA fire-sprinkler-permit and/or fire-alarm-permit (this file's entries) is required independently of the Town's own review
