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 (A.R.S. Title 9). The City of Casa Grande runs its own Planning & Development Department / Development Center and independently adopts and administers its own construction codes under Title 15 (Buildings and Construction) of the Casa Grande Code of Ordinances; it does not defer permitting to Pinal County.

Permit types & fees
Residential Building Permit (New Construction)
Required for new single-family and two-family dwelling construction in the City of Casa Grande. Reviewed against the 2018 IRC and City of Casa Grande amendments under Title 15, plus the City's Building and Technical Administrative Code (CG-BTAC, 2019 Edition as amended 2022). Applications are submitted at the Development Center (510 E. Florence Blvd.).
Residential Addition / Remodel / Minor Alteration Permit
Required for room additions, remodels, and other alterations to existing one- and two-family dwellings in Casa Grande. Reviewed against the 2018 IRC as adopted and amended by the City. Classified as 'Addition/Alterations' on the City's A.R.S. § 9-835 review timeframe chart.
Electrical Permit
Required for electrical installation, alteration, or repair work in Casa Grande, governed by the 2017 National Electrical Code (NEC) as adopted and amended by the City. Billed as a flat fee per the Consolidated Fee Schedule's 'Electrical, Mechanical, Plumbing Permit' category.
Plumbing Permit
Required for plumbing installation, alteration, or repair work in Casa Grande, governed by the 2018 International Plumbing Code (IPC) as adopted and amended by the City. Includes gas line repair/replacement, which requires City inspection before the gas utility restores service.
Mechanical / HVAC Permit
Required for heating, ventilation, and air conditioning installations in Casa Grande, governed by the 2018 International Mechanical Code (IMC) as adopted and amended by the City. New and replacement HVAC equipment must be sized per ACCA Manual J & S with minimum efficiency thresholds published by the Building Department.
Re-Roofing Permit
Required for residential and commercial re-roofing in Casa Grande, governed by the 2018 IBC/IRC roofing provisions. The City offers both an in-person-inspection track and a lower-cost drone-inspection track, each billed as a flat fee inclusive of plan review.
Residential Solar Photovoltaic (PV) / Battery ESS Permit
Required for installation of rooftop residential solar photovoltaic systems (or battery energy storage systems) in Casa Grande. Solar permits are billed as a flat fee under the Solar System Permits category of the Consolidated Fee Schedule, drawn from the Building Permit Fee table. Applications are processed through the Land Use Application Processing system as 'Solar (Photovoltaic or Battery/ESS)'.
Demolition Permit
Required for demolition of any residential or commercial structure in Casa Grande. Billed as a flat fee and classified under the Miscellaneous category on the City's A.R.S. § 9-835 review timeframe chart, alongside single-trade permits.
EV Charger / EVSE Permit
Casa Grande has no standalone EV-charger/EVSE permit type or fee line item. Installing electric vehicle charging equipment (e.g., a dedicated 240V Level 2 circuit or panel/service work to support a charger) is electrical work, governed by the 2017 National Electrical Code (NEC) as adopted by the City, and is billed under the same flat 'Electrical, Mechanical, Plumbing Permit' consolidated fee category documented in this file's own electrical-permit entry -- not a distinct EV-charger line item. The City's FY 2025-2026 Consolidated Fee Schedule and Building Department page were checked directly and contain no EV-charger, EVSE, or electric-vehicle-specific fee or process, and no evidence was found that Casa Grande participates in SolarAPP+ (gosolarapp.org) or another instant/automated EV-charger permitting platform as of this review.
Sign Permit (Commercial/Business Signage)
Required for new building or site signage in Casa Grande, including wall signs, monument signs, and other permanent commercial signage, reviewed against the City's Sign Code (Casa Grande Code of Ordinances Title 17, Article III. Signs) by the Planning & Development Department at the Development Center. Billed per square foot of sign area with a stated minimum, per the City's own Sign Permit Application -- the FY2025-2026 Consolidated Fee Schedule itself does not print a dollar figure for this line item and instead defers to 'See Description.'
Fire Sprinkler & Fire Alarm Permit
Required for installation of automatic fire sprinkler systems (NFPA 13/13R), fire alarm and detection systems, standpipe systems, and related fire-suppression water-supply equipment (fire pumps, suction tanks) in Casa Grande. Reviewed directly by the City of Casa Grande Fire Department's own Fire Prevention Division (headed by a Fire Marshal) against the 2018 International Fire Code (IFC) as adopted and amended by the City -- Casa Grande does not defer fire plan review to Pinal County. Applications and plans are submitted through the 'Development Center - Fire' using a single combined Fire Department Permit Application that itemizes sprinkler, standpipe, fire pump, and fire alarm fees together, so this file uses one combined permit-type entry rather than splitting sprinkler and alarm into separate products.
Certificate of Occupancy / Change of Occupancy Permit
Required whenever a building in Casa Grande is occupied for the first time, or when there is a change of tenancy, ownership, or use of an existing building or tenant space. Governed by Casa Grande Code of Ordinances Title 15, Article IV (Issuance of Building Permits and Certificates of Occupancy). Any new business location, change of ownership, or change of use requires an occupancy inspection conducted jointly by the Building Department and the Fire Department before occupancy is authorized. Casa Grande runs two distinct tracks: a construction-involved 'Change of Occupancy / Major Alteration / T.I.' commercial building permit, and a no-construction 'Change of Occupancy Permit' (billed as the flat-fee Occupancy Permit) for a simple tenant, ownership, or use change to an already-code-compliant space.

Tips & gotchas
- Arizona has no statewide mandatory building code — the City of Casa Grande independently adopts and amends its own construction codes under Title 15 of its Code of Ordinances and runs its own Planning & Development Department / Development Center; it does not defer to Pinal County for permitting within city limits.
- Casa Grande's adopted code suite is one full ICC cycle behind some neighboring Arizona cities: 2018 IBC/IRC/IMC/IPC/IFGC/IFC/IECC/IPMC/ISPSC plus 2017 NEC, per the Building Department's own Quick Codes Design Criteria Handout (rev. 11/8/2024) — always confirm against the live handout in case of a subsequent code-cycle update, since AZBO directory listings (2018 IRC/2017 NEC) matched exactly at time of verification.
- The 2019 City of Casa Grande Building and Technical Administrative Code (CG-BTAC), amended in 2022, is a locally-authored administrative code layered on top of the ICC model codes (Resolution 5170 base, Resolution 5397 amendment) — it governs permit administration and technical amendments distinct from the model code text itself.
- Design criteria: 115 mph ultimate wind speed (Exposure C), Seismic Design Category B, 34°F winter design temperature, heavy termite potential (certificate of soil treatment required), 0-inch frost line depth, 0 psf ground snow load, negligible weathering — all site-specific per IBC Chapter 16/ASCE 7-16 for IBC-designed buildings.
- Only three permit categories are billed as flat fees rather than ICC-valuation-based: swimming pools, electrical/mechanical/plumbing single-trade permits, and solar/battery-ESS permits. Everything else (new construction, additions, re-roofing, demolition) uses either the ICC Building Valuation Table tiers or a separately published flat fee specific to that permit type (e.g., $100 demolition, $125/$400 roofing).
- Maximum Building Permit Fee is capped at $150,000 regardless of project valuation, per the FY 2025-2026 Consolidated Fee Schedule.
- Casa Grande publishes a formal A.R.S. § 9-835 'Over-All Review Timeframes for Building Permits' chart (via its Regulatory Bill of Rights Directory) with a uniform structure: every permit classification gets a 2-business-day Administrative Completeness Review, followed by Substantive Review split into 'Review of Initial Submittal' and 'Review of Resubmittal and Staff Decision to Approve/Deny' stages (each ranging 10-30 business days depending on classification), summing to an Over-All Timeframe of 24-64 business days depending on project type.
- Detached accessory structures 200 sq ft or less (residential) / 120 sq ft or less (commercial) with NO utility connections (electric, water, sewer) do not require a building permit — but Planning Department approval for size/height/setback compliance is still mandatory, a distinction easy to miss.
- Re-roofing offers two flat-fee tracks: standard in-person inspection ($125, plan review included) or drone inspection ($400, plan review included) — maximum two layers of roof covering, no ice barrier underlayment required given the desert climate.
- New/replacement HVAC must meet City-published minimums beyond the base IECC: 80% AFUE gas furnaces/boilers, 14 SEER air conditioners/heat pumps, sized per ACCA Manual J & S, with duct insulation per ACCA Manual D (R-8 attic/exterior, R-6 elsewhere).
- Building inspections are scheduled through the WebPermits portal (rogue.casagrandeaz.gov/WebPermits); the City does NOT offer same-day inspections unless requested by 11:59 p.m. the prior business day, and inspectors run routes between 6 a.m. and 3:30 p.m.
- Gas line repairs require a City permit and passed inspection BEFORE the gas utility will restore service — this is a hard prerequisite, not a parallel step.
- This is one of PermitBase's first two Pinal County jurisdictions (alongside Florence, built in parallel) — Pinal County itself was not yet covered by any prior PermitBase jurisdiction file as of this build.
