Commercial Building Permit in Tombstone, Arizona
Required for commercial construction, enlargement, alteration, repair, improvement, moving, conversion, or demolition within Tombstone city limits. Tombstone has NO separate commercial permit track: commercial work uses the exact same unified Building Permit Application as residential work — the form's Permit Information section is simply 'Permit Type: ☐Residential ☐Commercial' — with the same valuation-based fee table, the same 11-stage inspection sequence, and the same Certificate of Occupancy requirement. The one commercial-specific submittal requirement printed on the form itself is: 'Commercial Projects may require a Professional Architect and/or Engineer.' Because Tombstone's downtown commercial core (the Allen Street National Historic Landmark District area) sits almost entirely within the Schieffelin Historic Preservation District, most real-world commercial projects must first obtain a Historic Preservation Commission Certificate of Appropriateness (see this file's historic-district-certificate-of-appropriateness entry) before the building permit may even be submitted/approved.

When you need this permit
- Building permit required to 'Construct, Enlarge, Alter, Repair, Improve, Move, Convert, Demolish any building, utilities, or structure,' per Tombstone City Code Section 3-1-1 as restated on the Building Permit Application (Rev. 1/2024), page 3
- Use the City's single unified Building Permit Application with the 'Commercial' Permit Type checkbox — no commercial-specific application form exists (confirmed live 2026-08-01: the Forms & Permits page lists 33 forms and only one generic 'Building Permit Application'; no commercial or tenant-improvement form)
- 'Commercial Projects may require a Professional Architect and/or Engineer' — verbatim, bolded/underlined, on page 4 of the Building Permit Application (Rev. 1/2024); whether a stamp is required for a given project is at the Building Official's determination, and the official may also require engineering data or product information when requested
- Reviewed against the City's adopted 2006 IBC (Tombstone City Code Section 3-1-1), 1988 NEC (Section 3-1-4), and 1988 UPC (Section 3-1-5) — see codesAdopted for the full vintage discussion
- Full project drawing set required per the application's Minimum Requirements: Plat Plan, Floor Plan, Exterior Elevations, Crosscut Sections, Mechanical Plan, Plumbing Plan, and Electrical Plan (minimum 1/4 inch = 1 foot scale, 8.5x11 minimum sheets, consecutively numbered with title block)
- A.R.S. Title 32 contractor licensing required: for commercial work the Owner/Builder exemption under A.R.S. 32-1121A.5 is effectively unavailable, since the form's own text limits it to property 'intended for sole occupancy by the owner, not intended for occupancy of member of the public, owner's employees or business visitors' — a commercial building fails that test; the practical alternatives are a licensed ROC contractor or the 32-1121A.6 Owner/Developer route (which itself requires contracting a licensed General Contractor and listing all contractors' ROC numbers on the application) Owner-builderContractor
- The application's Official Use Only block records Occupancy Group, Building Type, and Building Area (under roof) — IBC occupancy classification is assigned by the Building Official at issuance
- Properties within the Schieffelin Historic District require a Historic Preservation Commission Certificate of Appropriateness BEFORE building permit submission/approval, per the application's own bolded header notice — for exterior work, new construction, signs, and any material change in exterior appearance visible from a public street or alley (Tombstone City Code Section 10-19-4); see this file's historic-district-certificate-of-appropriateness entry for the full COA process, 21-day report timeline, and 90/180-day completion deadlines
- Permit expires 6 months from issuance; extension of up to 60 additional days available upon application (Tombstone City Code, Title 3)
- Certificate of Occupancy required before any new construction may be occupied or used — 'You must obtain a certificate of occupancy before you can occupy or use any new construction' (Building Permit Application, page 4)

Tips
- There is NO separate commercial permit process in Tombstone — confirmed live 2026-08-01 by fetching the Forms & Permits page (33 forms listed; the only building application is the single generic 'Building Permit Application') and reading the application PDF in full: commercial is a checkbox ('Permit Type: ☐Residential ☐Commercial') on the same unified form, with the same valuation fee table, plan-review percentages, 11-stage inspection sequence, and Certificate of Occupancy requirement as residential work. The commercial-specific deltas are exactly three: (1) 'Commercial Projects may require a Professional Architect and/or Engineer' (application, page 4); (2) commercial-specific Engineering and P&Z fee lines (Commercial Site Improvement Plan Review $500/sheet; Site Plan - Commercial $900 + $30/acre); (3) the practical unavailability of the A.R.S. 32-1121A.5 owner/builder exemption for buildings open to the public, employees, or business visitors. Owner-builder
- TENANT IMPROVEMENT IS NOT A DISTINCT PERMIT TYPE in Tombstone — this is why this file has no commercial-tenant-improvement-permit entry. Chase trail (2026-08-01): the Forms & Permits page lists no TI application; the Building Permit Application's Class of Work options are New / Repair-Replace / Sign / Utility / Row / Other with no TI category (a TI would be filed as 'Commercial' + 'Repair/Replace'); the Fee Schedule (effective 11/14/2025, re-read in full) contains no TI, remodel, or build-out line item anywhere — TI work is billed on the same 'Permits by Valuation' table as everything else. Unlike large AZ cities (Phoenix, Maricopa, Queen Creek) that publish dedicated commercial TI guides, Tombstone publishes nothing TI-specific.
- HISTORIC DISTRICT IS THE REAL COMMERCIAL GATEKEEPER: Tombstone's downtown commercial core (Allen Street and surrounds — the National Historic Landmark District that draws the city's tourism economy) sits almost entirely within the Schieffelin Historic Preservation District overlay, so in practice most commercial projects route through the Historic Preservation Commission Certificate of Appropriateness BEFORE the building permit — see this file's historic-district-certificate-of-appropriateness entry for the full process (21-day inspector-report step, Commission vote at public meeting, 10-day signature window, 90/180-day completion deadlines). Note the COA trigger standard for commercial TI work specifically: interior-only improvements not visible from a public street or alley are NOT enumerated COA triggers under Section 10-19-4, but storefront changes, signs, light fixtures, paint-scheme/material changes, and anything else 'visible from a public street or alley' ARE. Storefront signage has its own fee lines ($100 first sign including plan review and 2 inspections, $25 each additional sign) and its own form (Historic District Sign and Construction Application, current packet revision 20260303).
- CONFIRMED GAP — commercial review timeline: re-verified 2026-08-01 that the City publishes no plan-review turnaround for commercial (or any) permits, and no A.R.S. § 9-835 time-frames posting exists on cityoftombstoneaz.gov. The only published levers on speed are the 'Expedited Permits... Double the rate' fee line and the Historic District COA's own 21-day report step. Budget schedule risk accordingly and get a verbal estimate from the Building Official (520-457-3415) before committing to a tenant possession or opening date.
- The fee schedule's 'Commercial Site Improvement Plan Review' ($500/sheet, Engineering section) and 'Site Plan - Commercial' ($900 + $30/acre, P&Z section) exist as published fee lines, but the City publishes no threshold criteria for when a commercial project triggers engineering-level site review or formal P&Z site plan review versus building-permit-only review — this is disclosed as unknown rather than guessed; confirm scope and total fee stack with the Building Official before budgeting a project.
