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 under state enabling statutes (e.g., A.R.S. Title 9 for municipalities). The City of Douglas independently adopts and administers its own construction codes through its Development Services Department (Building Safety and Planning & Zoning Divisions).

- 2005 National Electrical Code (NEC/"NEL"), used by the City of Douglas for electrical plan review and inspections — this is an older edition than most Arizona municipalities in the PermitBase dataset (compare Buckeye's 2023 NEC), and was independently verified as still current via the City's live 'Building Code Update Notice' (posted on the Building Permit & Plan Review page as of this review), which states the City is 'currently reviewing the International Building Code (IBC) and the International Residential Code (IRC) for potential adoption for updated standards' — i.e., as of this review the update has NOT yet been formally adopted, so the 2006/2005 code set remains the officially adopted baseline.

- Work requiring a licensed contractor: any work requiring a permit (except interior non-structural remodeling under $1,000 in project value) must be performed by an Arizona Registrar of Contractors (ROC) licensed contractor, unless the owner qualifies for the owner/builder/occupant exemption under A.R.S. § 32-1121.A.5 (owner-occupant, no rental/sale within one year) or the owner/developer exemption under A.R.S. § 32-1121.A.6 (contracting with ROC-licensed contractors, listed on the application).

Permit types & fees
Residential Building Permit (New Construction)
Required for new single-family, multifamily, and mobile/manufactured-home construction in the City of Douglas. Reviewed against the City's adopted 2006 IBC/IRC. The Residential Building Permit Application is a single, unified application used for ALL single-family, multifamily, and mobile-home-related projects, including their associated electrical, plumbing, and mechanical work.
Residential Addition / Remodel / Accessory Structure Permit
Required for room additions, structural remodels, garages, carports, decks, ramadas, and accessory buildings (including ADUs) on existing one- and two-family dwellings in Douglas, submitted on the same Residential Building Permit Application used for new construction.
Electrical Permit
Required for electrical installation, alteration, panel upgrades, or repair work in Douglas, including electric meter repair/replacement/inspection and photovoltaic (PV) electrical connections, submitted on the Residential Building Permit Application.
EV Charger / EVSE Permit (Electrical Permit)
Installation of an electric vehicle charging station in Douglas, Arizona is electrical work, submitted on the same Residential Building Permit Application (Mechanical-Electrical/RME permit type) used for this file's general electrical-permit entry. The City of Douglas Development Services fee schedule (FAQ Bilingual, DocumentCenter View 5479, directly fetched and reviewed page-by-page this session) lists flat trade-permit fees by category (Plumbing, Electrical, Mechanical, Solar/PV Systems & Wind Turbines, Re-Roof, Paving, Demolition, etc.) but has NO distinct 'EV charger,' 'electric vehicle,' or 'EVSE' line item — an EV charger circuit falls under the general flat 'Electrical' fee line, the same one used for any other electrical work (panel upgrades, wiring, outlets).
Plumbing Permit
Required for plumbing installation, alteration, or repair, including gas line testing/inspection, water heaters, and fixture work in Douglas.
Mechanical / HVAC Permit
Required for heating, ventilation, air conditioning, and gas appliance installations in Douglas, governed by the City's adopted 2006 International Mechanical Code (IMC).
Re-Roofing Permit
Required for residential and commercial re-roofing in Douglas. A residential building permit is explicitly required for 'doing a re-roof' per the City's Development Services FAQ.
Residential Solar Photovoltaic (PV) / Wind Turbine Permit
Required for installation of rooftop or ground-mounted residential solar photovoltaic systems and wind turbines in Douglas. A residential building permit is explicitly required for 'getting a solar panel system' per the City's Development Services FAQ, with the electrical scope captured on the standard Residential Building Permit Application's PV Array section.
Demolition Permit
Required for demolition of structures in Douglas, published as its own flat-fee line item on the City's fee schedule.
Sign Permit (Building Permit for Sign)
Required for erecting, repairing, altering, relocating, or maintaining most signs (business/commercial signage, illuminated signs, electronic message boards/digital displays, and portable commercial signs over six square feet) within the City of Douglas, per Article 7 (Supplementary District Regulations - Signs) of the Douglas Zoning Code. The 'Building Permit for Sign' is issued by the Building Inspector and applies citywide (Article 7 governs signage in every zoning district, cross-referenced from each district's own 'Sign Regulations' section in Article 5); it is not limited to commercial districts, though most permitted sign area/height allowances for business signage are set out in Sec. 709 for nonresidential zoning categories (NC, OP, GC, IP, LI, HI, and AA).
Fire Sprinkler & Fire Alarm System Permit (Arizona Office of the State Fire Marshal Plan Review)
The City of Douglas has its own municipal Fire Department (established 1902; Fire Chief and Assistant Fire Chief; 8 square miles of city service area), but that department's published services are limited to suppression, EMS, hazmat response, and business/home safety inspections - it does not list plan review or permitting for fire protection systems. Confirmed directly against the Arizona Department of Forestry and Fire Management (DFFM)/Office of the State Fire Marshal (OSFM) 'Plan Review - Permitting and Inspection' page: Arizona's state fire code review authority applies to 'areas without a locally adopted fire code,' and the DFFM page's own list of 'Cities with Enacted Ordinances' that hold local jurisdictional authority for fire-system plans, permitting, and inspections names only Chandler, Gilbert, Goodyear, Glendale, Mesa, Scottsdale, Surprise, and Yuma - Douglas is not among them. This is consistent with this file's already-verified codesAdopted note that for commercial projects, Douglas applies the Fire Code edition adopted by the Arizona State Fire Marshal rather than enforcing its own edition locally. As a result, new installation or modification of automatic fire sprinkler systems and fire alarm systems in Douglas (commercial/multi-family construction in particular) are submitted to OSFM's own Permit and Plan portal for state-level plan review and permitting, not to the Douglas Fire Department or Development Services.
Certificate of Occupancy / Change of Use (Business License Occupancy Classification Review)
The City of Douglas does not operate a standalone 'Change of Use Permit' application separate from its Business License process. Confirmed directly against the City's Business Licenses page: any business opening or changing use within city limits must obtain a Business License, during which 'the application will be reviewed and building classification determined for the occupancy certificate' - i.e., the change-of-use/change-of-occupancy determination happens as part of Business License intake, combined with Planning & Zoning clearance and a flat Certificate of Occupancy fee charged through the Development Services fee schedule (used for both new construction and any project requiring a new/updated occupancy determination).

Tips & gotchas
- Arizona has no statewide mandatory building code — the City of Douglas independently adopts and administers its own construction codes through its Development Services Department (Building Safety and Planning & Zoning Divisions).
- Douglas is a genuinely old code-edition city, verified as still current at the time of this review: 2006 IBC/IRC/IMC and 2005 NEC, per the City's own Development Services FAQ (Bilingual). The City's live Building Permit & Plan Review page posts a 'Building Code Update Notice' stating it is reviewing IBC/IRC updates, but as of this review no new edition has been formally adopted — so this is confirmed current data, not stale/outdated research.
- Fire Code is a partial exception to the old-edition pattern: for commercial projects, Douglas applies the most recent Fire Code edition adopted by the Arizona State Fire Marshal, rather than its own older 2006 IFC.
- The Residential Building Permit Application is a single unified form covering ALL single-family, multifamily, and mobile-home-related projects, including their associated electrical, plumbing, and mechanical work — there is no separate standalone electrical/plumbing/mechanical application.
- Douglas fees are predominantly FLAT dollar amounts per permit type (e.g., $100 residential electrical, $45 residential plumbing, $50 residential mechanical, $50 re-roof, $15 demolition) rather than valuation-based, except for new construction/additions which use the City's valuation-based Plan Review and Inspection Fee table plus per-square-foot valuation rates.
- All NEW CONSTRUCTION incurs separate Water and Wastewater Impact Fees (scaled by meter size) plus a $943 Water Tap Fee — these are billed in addition to, not instead of, the building/plan-review permit fee.
- Review timelines are two-tiered: miscellaneous/trade permits (fences, gas, electrical, mechanical, plumbing, porches, ramadas, re-roof, solar, demolition) are targeted at 2-3 business days; new residential construction averages about one week; new commercial construction averages about four weeks. Source: City of Douglas Development Services FAQ (Bilingual).
- Permit validity is 6 months (180 days) for most permit types, but extends to 18 months for a new single-family dwelling or new commercial space permit; any extension requires a written request to Development Services and permits cannot be extended more than once.
- Fence height limits: 3 feet for the front yard and first 25 feet of a side yard from the front property line, 6 feet for the back yard and remaining side yard, per the current bilingual FAQ (this superseded a simpler 'flat 6 ft back/side, 3 ft front' statement in the City's older, pre-bilingual FAQ).
- Owner/builder and owner/developer licensing exemptions under A.R.S. § 32-1121.A.5 and A.R.S. § 32-1121.A.6 are both explicitly supported via a dedicated Contractor Affidavit section on the Residential Building Permit Application.
- No dedicated ADU-specific checklist, application, or fee line was found on the City of Douglas's published materials — ADU is now its own checkbox option on the standard Residential Building Permit Application, but is understood to be processed through the same general residential building permit fee/review process; no distinct ADU-specific fee or timeline was separately published by Development Services at the time of this review.
- This is the first Cochise County jurisdiction added to PermitBase's Arizona coverage.
