Commercial Building Permit in Dewey-Humboldt, Arizona
Dewey-Humboldt has no separate commercial building permit application. Confirmed directly from the Town's own Building Permit Application PDF (page 1 of 13, dhaz.gov/DocumentCenter/View/101/Building-Permit): the form's 'Permit Type' field offers only two checkboxes, 'Residential' and 'Other' -- commercial, industrial, assembly, and multi-family (3+ unit) projects are submitted on the identical form used for new home construction, simply by checking 'Other' instead of 'Residential' and entering the Project Valuation. Commercial construction is governed by the 2018 IBC (Dewey-Humboldt Code of Ordinances § 150.02) rather than the 2018 IRC, which by the Town's own administrative-code structure applies only to detached one- and two-family dwellings and townhouses (a distinction independently confirmed in a 2019 draft ordinance packet, dhaz.gov/DocumentCenter/View/2765, § 101.4.1 Building Code vs. § 101.4.10 Residential Code, consistent with the currently codified § 150.02/§ 150.03 split cited elsewhere in this file). Tenant improvement or remodel work on an EXISTING commercial building is likewise folded into this same general Building Permit process rather than issued as a separate product: no standalone 'tenant improvement permit,' TI-specific form, or TI-specific fee line was found anywhere on the Town's site, Printable Forms page, or Appendix A fee schedule; a commercial TI/remodel is processed under the 2018 International Existing Building Code (§ 150.09, already documented in this file's change-of-use-permit entry) governing repair, alteration, and change of occupancy of existing buildings. Because no genuinely distinct TI process or fee was found, a separate commercial-tenant-improvement-permit entry is NOT added to this file.

When you need this permit
- 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) Contractor
- 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

Tips
- There is no dedicated 'Commercial Building Permit' form -- use the same Building Permit Application as a new home, checking 'Other' instead of 'Residential.'
- Because Appendix A bills non-single-family plan review at 'actual cost of professional services and materials' (rather than a flat pass-through fee), commercial plan-review cost and timeline both scale with project complexity in a way the residential track does not -- budget accordingly and get a scope-specific estimate from Building Safety before assuming residential-track pricing or speed.
- A commercial tenant improvement or remodel is not a separate permit product in Dewey-Humboldt -- it goes through this same Building Permit Application under the adopted 2018 International Existing Building Code's change-of-occupancy/alteration provisions (§ 150.09).
- New or modified fire sprinkler/alarm systems are never reviewed or fee'd by the Town itself -- submit those directly to CAFMA (928-772-7711, www.cazfire.gov), independent of and in addition to the Town's commercial building permit.
