  • Permit required to construct, enlarge, alter, move, demolish or change occupancy of a building or structure, or to erect/install/enlarge/alter/repair/remove/convert/replace any electrical, gas, mechanical or plumbing system regulated by code (Development Services Fee Schedule, Section A.1 — identical in both the Resolution 2006-10 and Resolution 2008-75 versions)

Fee schedule

Construction Fee — Based on Valuation (Table 1)Development Services Fee Schedule, Table 1 (identical in Resolution 2006-10 and Resolution 2008-75 versions, both re-verified 2026-08-01). Valuation is the greater of the customer-provided figure or area (sq ft) multiplied by the Fee Schedule's Commercial Building Valuation Data table (Section K), which lists per-square-foot factors by occupancy and construction type — e.g., Offices Type V-B $52.15/sq ft, Stores Type V-B $36.57/sq ft, Restaurants Type V-B $65.60/sq ft, Warehouses Type V-B $21.16/sq ft (deduct 11% for mini-warehouses), Industrial Plants Type V-B $28.86/sq ft, Banks Type V-B $80.03/sq ft; commercial Air Conditioning adds $3.20/sq ft and Fire Sprinklers $2.01/sq ft; add 0.5% to total for each story over three on starred occupancies.
$23.50 ($1-$500 valuation); $23.50 for the first $500 plus $3.00 per additional $100 or fraction to $2,000; $68.50 for the first $2,000 plus $14.00 per additional $1,000 or fraction to $25,000; $390.50 for the first $25,000 plus $10.00 per additional $1,000 to $50,000; $640.50 for the first $50,000 plus $7.00 per additional $1,000 to $100,000; $990.50 for the first $100,000 plus $5.50 per additional $1,000 to $500,000; $3,233.75 for the first $500,000 plus $4.75 per additional $1,000 to $1,000,000; $5,608.75 for the first $1,000,000 plus $3.75 per additional $1,000 above $1,000,000
Plan Review FeeDevelopment Services Fee Schedule, Section E.3.a
65% of the Construction Fee
Plumbing / Mechanical / Electrical Fees (as applicable to scope)Development Services Fee Schedule, Section E.3.b-d; a full-trade commercial building permit totals Construction Fee + 65% + 25% + 25% + 25%, plus sewer-tap connection and impact/development fees as applicable (Section E.4; the Resolution 2008-75 version cross-references A.R.S. § 9-463.05 for development fees)
25% of the Construction Fee each, minimum $30.00 each
Tenant Improvement Valuation Adjustment (billed under this same permit)Development Services Fee Schedule, Section K footnote (***) attached to the Offices occupancy line. Tenant improvements have no separate permit type, fee table, or timeline in Willcox — the TI percentage adjusts the per-square-foot valuation from which the standard Table 1 Construction Fee (and its 65%/25% add-ons) is then calculated. The footnote's minor/major percentages are quoted verbatim as printed; the City does not further define 'Minor' vs 'Major' tenant improvement anywhere in the published schedule — confirm classification with the Building Safety Division.
Per the Commercial Building Valuation Data footnote (verbatim): 'Use 20 percent for Minor tenant improvements use 10 percent for Major tenant improvements and deduct 20 percent for shell only'
Type 2 Grading — Commercial Site Grading (if site grading is in scope)Development Services Fee Schedule, Table 2 (Grading). Major grading, subdivision grading, and commercial site grading are all Type 2.
$100.00 base fee plus the greater of $500.00 or 1% of construction cost; AT-RISK grading $500.00
Commercial Development Plans Review (planning-level site review, if applicable)Development Services Fee Schedule, Table 3 (Planning & Zoning). Amendments/modifications/extensions and additional submittals are each 50% of the original fee. This is a separate planning-level review that applies to commercial site development, on top of the building-permit fees.
$1,000.00 for up to 5 acres of commercial or multi-family property, plus $50.00 each additional acre over 5; plus $100.00 each for Title Report, Drainage Report (up to 5 acres, +$10/additional acre), Archeology Report, Phase 1 Environmental Assessment, Traffic Impact Analysis, Geological Technical Reports, and misc. document reviews
Re-inspection FeeDevelopment Services Fee Schedule, Section F.2; inspections outside normal business hours are $40.00/hr (2-hour minimum, Section F.1), and plan review of revisions to already-approved plans is $40.00/hr (Section F.8)

Tips

  • Tenant improvements are NOT a distinct permit type in Willcox. The only TI-specific provision anywhere in the City's published materials is a valuation footnote in the Fee Schedule's Commercial Building Valuation Data table (Section K, attached to the Offices line): 'Use 20 percent for Minor tenant improvements use 10 percent for Major tenant improvements and deduct 20 percent for shell only.' A TI is applied for, reviewed, fee-calculated (Table 1 + percentage add-ons), and inspected as a standard commercial building permit — this dataset therefore carries no separate commercial-tenant-improvement-permit entry for Willcox.
  • The 30-business-day commercial review figure (about 6 calendar weeks) comes from the City's own Building Plan Guidelines, re-verified live 2026-08-01 — the same document also commits to 10-business-day resubmittal checks and notes 'smaller projects may be reviewed initially within 4 business days,' which the Building Official may apply to small commercial scopes at their discretion.
  • The City publishes a required-inspections handout for RESIDENTIAL projects only (REQUIRED-INSPECTIONS.pdf is titled 'Residential Required Inspections'); no commercial-specific inspection-sequence handout is published. The commercial inspection list above is drawn from 2018 IBC § 110.3 as adopted by Ordinance NS374 plus the special-inspection language in the Building Plan Guidelines — confirm the exact card of required inspections with the Building Safety Division at permit issuance.
  • Despite Willcox's wine-country and agricultural economy, the City publishes NO agricultural-building or winery-specific permit category, fee line, exemption, or valuation entry anywhere in its Development Services Fee Schedule, its Ordinance NS374 code amendments (the amended IBC § 105.2 exemption list contains no agricultural-building exemption), or its Building Permits page (all re-checked 2026-08-01). A winery tasting room, production building, or barrel warehouse inside city limits is permitted as a standard commercial occupancy — e.g., the Section K 'Restaurants'/'Stores' lines for tasting rooms or 'Industrial Plants'/'Warehouses' lines for production and storage. (Most Willcox-area wineries and vineyards sit outside city limits in unincorporated Cochise County, where county — not city — permitting applies.)
  • Commercial projects face two fee layers the residential entries in this file don't: Type 2 commercial site grading ($100 base + greater of $500 or 1% of construction cost) and the planning-level Commercial Development Plans review ($1,000 up to 5 acres plus per-report adders) under Table 3.
  • The Water Conservation Code fixture standards inserted into the adopted 2018 IPC are MANDATORY for new commercial/industrial/public construction (auto-closing lavatory faucets, ≤3 gpm showerheads, ≤1.6 gal/flush water closets, waterless urinals, evaporative-cooler water recycling) — unlike the residential provisions, which are 'requested but not required.'

Frequently asked questions

It depends on A.R.S. § 32-144, not city ordinance. Per the City's own guidance document, a registered design professional is generally required when the building exceeds 3,000 sq ft, the occupant load is 21 or more, or structural spans exceed 20 feet — many small commercial projects below all three thresholds can proceed without an architect's or engineer's seal, at the Building Official's discretion to require more.

In Willcox, the published Construction Fee — Based on Valuation (Table 1) is: $23.50 ($1-$500 valuation); $23.50 for the first $500 plus $3.00 per additional $100 or fraction to $2,000; $68.50 for the first $2,000 plus $14.00 per additional $1,000 or fraction to $25,000; $390.50 for the first $25,000 plus $10.00 per additional $1,000 to $50,000; $640.50 for the first $50,000 plus $7.00 per additional $1,000 to $100,000; $990.50 for the first $100,000 plus $5.50 per additional $1,000 to $500,000; $3,233.75 for the first $500,000 plus $4.75 per additional $1,000 to $1,000,000; $5,608.75 for the first $1,000,000 plus $3.75 per additional $1,000 above $1,000,000.

These are the jurisdiction's own published figures — see the fee schedule table and source citations on this page.

30 business days (about 6 calendar weeks) per the City of Willcox Building Plan Guidelines, with resubmittals checked within 10 business days. This published figure serves as the City's A.R.S. § 9-835 licensing-timeframe disclosure for commercial plan review.

No. Tenant improvements are processed as standard commercial building permits. The Fee Schedule's Commercial Building Valuation Data table adjusts the per-square-foot valuation for TIs (verbatim footnote: 'Use 20 percent for Minor tenant improvements use 10 percent for Major tenant improvements and deduct 20 percent for shell only'), and the standard Table 1 Construction Fee plus the 65% plan review and 25% trade fees are then calculated from that adjusted valuation.

No. The City publishes no winery- or agricultural-building-specific permit category, fee line, or exemption. A winery facility inside Willcox city limits is permitted as a standard commercial occupancy under the 2018 IBC as adopted (e.g., valued on the Fee Schedule's Restaurants/Stores lines for a tasting room or Industrial Plants/Warehouses lines for production and storage). Wineries outside city limits fall under Cochise County permitting instead.
