Codes adopted
Arizona has no statewide building code for non-state buildings; codes are adopted locally. According to the International Code Council, codes are adopted locally in Arizona and are predominantly the I-codes, with different cities and counties choosing their own editions and local amendments. The Arizona State Fire Code (adopting the 2018 IFC) applies only to state and county buildings, public and private schools, and non-residential occupancies in areas without a locally adopted fire code — it does not establish a statewide residential or commercial building code floor. Each city and county adopts its own code editions independently, resulting in different I-Code years and amendment sets across jurisdictions. There is no state-mandated minimum edition; enforcement is entirely local. Always confirm the adopted edition and any local amendments with the specific jurisdiction before submitting plans.
- Arizona has NO statewide mandatory building code floor for general construction — code adoption is a per-city/county authority. Santa Cruz County independently adopts and administers its own construction codes for unincorporated areas through its Building Department (a division of Community Development).

Independently corroborated by the 2018 Arizona Building Officials (AZBO) Directory, which lists Santa Cruz County as having adopted the 2012 IBC/IRC/IMC/IPC/IFC and 2011 NEC (https://www.azbo.us/documents/documents/2018_AZBO_Directory.pdf).
- Santa Cruz County has also adopted a Zoning and Development Code (separate from the building-safety codes above) regulating zoning matters, setbacks, landscaping requirements, and swimming pools, administered by the Community Development Department's Planning & Zoning division.

- A subsequent Building Safety Code Ordinance and an Excavation and Grading Ordinance are both currently published and linked directly from the Building Department page (Building Safety Code Ordinance: https://www.santacruzcountyaz.gov/DocumentCenter/View/970/Building-Safety-Code-Ordinance; Excavation and Grading Ordinance: https://www.santacruzcountyaz.gov/DocumentCenter/View/972/Excavation-and-Grading-Ordinance), confirming the Building Department's code set is still active and in force as of this review. The Building Safety Code Ordinance PDF (970) is a large scanned image file that could not be machine-OCR'd during this review — a genuine access limitation, not an unpublished-code gap, since its existence, title, and the underlying 2012 I-Code adoption are independently confirmed by the live department page and the Guidelines for Builders document.
- Grading permits are required in unincorporated Santa Cruz County for any grading exceeding 50 cubic yards, per Santa Cruz County Ordinance Nos. 2001-06 & 2007-05. A grading permit is issued only in conjunction with a building permit (with narrow exceptions for grading under Planning & Zoning jurisdiction or special cases approved by the Building Official).

Permit types & fees
Residential Building/Grading Permit (New Construction, Additions, Accessory Structures)
Required for new single-family/two-family residential construction, additions, and accessory structures in the unincorporated areas of Santa Cruz County. Reviewed against the 2012 IBC/IRC and 2011 NEC as adopted by the County. Grading (where cut/fill exceeds 50 cubic yards) is bundled into the same permit rather than issued standalone. Applications are submitted to the Building Department (Community Development) using the County's Building/Grading Permit Application, accompanied by the Plan Submittal Check List items.
Commercial/Multi-Family Building Permit (New Construction, Tenant Improvement)
Required for all new commercial, industrial, and multi-family construction, and any structure other than a single-family residence, in the unincorporated areas of Santa Cruz County. These projects require separate plan approval from the Santa Cruz County Planning and Zoning Department in addition to Building Department review, and carry a higher (50%) plan review fee rate than residential.
Minor Electrical, Solar, and Gas Permit
Flat-fee permit track for minor electrical work, solar installations, and gas work in the unincorporated areas of Santa Cruz County. Solar permits require stamped engineering for gravity and uplift loads. Exempt from the Zoning Clearance Fee that applies to site-plan-bearing permits.
Grading Permit (Standalone / Excavation and Grading)
Required in unincorporated Santa Cruz County for any grading exceeding 50 cubic yards, per Ordinance Nos. 2001-06 & 2007-05 and the County's Excavation and Grading Ordinance. Normally bundled with a building permit, but is administered under its own fee table (Table A-33-B, doubled) and its own dedicated ordinance.
Solar PV Permit
NOTE: this jurisdiction file already documents solar coverage under the bundled 'minor-electrical-solar-gas-permit' entry (a flat-fee track combining minor electrical, solar, and gas work); this standalone entry surfaces that same real, already-verified coverage under the corpus's standard solar-pv-permit slug for consistency and discoverability. Santa Cruz County processes residential solar PV installations under its flat-fee Minor Electrical, Solar, and Gas Permit track — solar installations specifically require stamped engineering for gravity and uplift loads and are exempt from the county's $50 Zoning Clearance Fee that applies to site-plan-bearing permits.
EV Charger / EVSE Permit
Santa Cruz County does not publish a distinct EV charger/EVSE fee line. Installing electric vehicle charging equipment in unincorporated Santa Cruz County is minor electrical work and falls under the county's flat-fee "Minor Electrical, Solar, and Gas Permit" track — the same $60 flat-fee category used for other minor electrical installations, exempt from the $50 Zoning Clearance Fee that applies to site-plan-bearing permits. Installation must comply with the adopted 2011 NEC.

Tips & gotchas
- Santa Cruz County's unincorporated-area building program is administered by the Building Department, a division of the Community Development Department (Planning & Building). It is entirely distinct from the incorporated City of Nogales' own Community Development Department — do not confuse the two; Nogales issues its own building permits and does not defer to the County. This is separately confirmed for Patagonia (also within Santa Cruz County): Patagonia is a confirmed-excluded non-independent town in this KB that defers building-permit administration to Santa Cruz County's Building Department — i.e., Patagonia parcels are permitted through exactly this county program.
- The Building Department observes business hours from 7:00 AM to 6:00 PM, Monday through Thursday only (no Friday hours). No applications are accepted and no permits are issued after 5:00 PM on those days.
- Two separate payments are required for every permit: one at plan submittal (Plan Review Fee + Zoning Clearance Fee), and a second when the permit is issued (the Building Permit Fee itself, calculated from Table 1-A valuation). The County will not accept multiple fee types combined onto a single check.
- A.R.S. §11-1605's statutory review-timeframe framework is not boilerplate here — Santa Cruz County has built its own Applicant's Certification and Acknowledgement page directly into the permit application, spelling out the 15-business-day administrative-completeness window, the 45-business-day total completeness-phase timeframe, the 105-business-day substantive review window, and the 150-business-day combined maximum County processing time, plus your own applicant response-time obligations (up to 270 business days combined if you use every extension).
- All structures other than single-family residences (commercial, industrial, multi-family) require a SEPARATE plan approval from the Planning and Zoning Department in addition to the Building Department's own review — budget extra lead time and a separate point of contact (520-375-7683) for these project types.
- Grading is not a standalone permit track in the ordinary case: any project disturbing more than 50 cubic yards of cut/fill has its grading review and fee (Table A-33-B, doubled) bundled into the same building permit application, not filed or paid separately.
- No permit will be issued without an approved street name/address giving access to the property. If your parcel needs an address assignment or is on an unnamed road, route through Planning & Zoning for an address verification letter (and, if needed, road-naming forms for 911 addressing) before applying for your building permit.
- This review could not locate a Building-Department-specific fee schedule newer than the 2014-dated 'Guidelines for Builders' Exhibit A/B tables on the County's current live site — the only 2025/2026-dated fee schedule currently linked from the County's Forms & Resources page is for Health Services (food service, septic, vital records), not Building Department permits. Confirm current-year building/grading fee amounts directly with the Building Department (520-375-7880) before relying on the 2014 figures for an active project.
- The Building Safety Code Ordinance (linked directly from the live Building Department page) is a large scanned-image PDF that could not be machine-read for this review — a genuine technical access limitation, not an unpublished-code gap; the underlying 2012 IBC/IRC/IMC/IPC/IFC + 2011 NEC adoption is independently confirmed by the live department page text and the Guidelines for Builders document, and further corroborated by the 2018 Arizona Building Officials (AZBO) Directory.
- Homes 3,600 sq ft or larger (living space + garage) require Fire Department sign-off — but only within the Rio Rico and Tubac Fire Districts, not county-wide.
- Commercial/multi-family projects (and any grading reviewed as part of a larger Development Plan under Planning and Zoning Department jurisdiction) go through the Technical Advisory Committee (TAC) — an interdepartmental review (Fire District, Community Development, Public Works, Flood Control, Environmental Health, and Building Dept.) with its own $300.00 fee (3 reviews included, $100.00 each additional review), separate from the Building Permit Fee, Plan Review Fee, and Zoning Clearance Fee.
