Solar Panel Permit Requirements in Arizona (2025–26)

• Bottom line: Yes, you need permits. Most Arizona solar installations require a building permit and an electrical permit from the local city or county, plus separate utility interconnection approval. Plan for a 4- to 10-week timeline from application to Permission to Operate (PTO).

Quick Answer: Do You Need a Permit for Solar Panels in Arizona?

Yes. Residential and commercial solar PV installations in Arizona require a building permit and an electrical permit from the local Authority Having Jurisdiction (AHJ), which is the city or county building department. There is no statewide solar permit, so requirements vary by jurisdiction, but no Arizona city or county is exempt.

Beyond local permits, you need utility interconnection approval from your electric provider, such as APS, SRP, or TEP. This process runs parallel to the permit process and is handled by the utility. You cannot legally energize a grid-tied solar system without the utility's Permission to Operate (PTO).

• HOAs cannot ban solar. Arizona law limits HOA authority over solar installations (A.R.S. § 33-1816). They can regulate placement but cannot prohibit the project.
• Your installer must be licensed. The Arizona Registrar of Contractors (ROC) requires solar installers to hold an appropriate license, typically an A-17 or C-11 classification. Verify licenses at roc.az.gov before signing a contract.
• Typical timeline: Expect 4–10 weeks from permit application to PTO, depending on your jurisdiction's plan review backlog and your utility's interconnection queue.

Arizona State Law: What the Statutes Actually Require

HOA Solar Rights

A.R.S. § 33-1816 prohibits homeowners associations from enforcing rules that effectively ban solar energy devices. An HOA may impose reasonable restrictions on placement and appearance, but those restrictions are unenforceable if they increase the system's cost by more than 10% or decrease its efficiency by more than 10% compared to the owner's preferred placement.

Municipal and County Authority

A.R.S. § 9-500.02 prohibits Arizona municipalities from adopting ordinances that effectively prohibit solar installations on private property. The parallel provision for counties is A.R.S. § 11-269.17. Cities and counties can regulate how solar is installed for safety and code compliance but cannot use zoning or ordinances to make installation impossible.

Contractor Licensing

A.R.S. § 32-1101 et seq. establishes the Arizona Registrar of Contractors and its licensing framework. Any contractor installing a solar PV system for compensation must hold a valid ROC license. The two most common classifications for solar work are:

• A-17 (Solar Energy Equipment): Covers solar thermal and PV system installation.
• C-11 (Electrical Contractor): Required for primarily electrical work, including inverter wiring, panel upgrades, and interconnection.

Some projects require both classifications. Consult the Arizona Registrar of Contractors (roc.az.gov) to confirm which applies to your scope of work.

Electrical Code

Arizona has adopted the National Electrical Code (NEC). The statewide baseline is NEC 2017, but individual jurisdictions may have amended locally to NEC 2020. Article 690 of the NEC governs solar photovoltaic systems, covering wiring, disconnects, rapid shutdown, and overcurrent protection. Confirm which edition your AHJ has adopted before finalizing system design, as NEC 2020 rapid shutdown requirements differ from the 2017 version and can affect equipment selection and cost.

Utility Interconnection and Net Metering

For investor-owned utilities like APS and TEP, interconnection standards and net metering rules are set by the Arizona Corporation Commission (ACC). Interconnection standards for distributed generation are codified in Arizona Administrative Code R14-2-2301 through R14-2-2308. The foundational net metering rules are in ACC Docket No. E-01345A-13-0248, but compensation rates are subject to ongoing docket activity. For current rates, consult the ACC directly at azcc.gov.

Salt River Project (SRP) is a political subdivision not regulated by the ACC. SRP administers its own interconnection program with different terms and compensation structures. Check SRP's current Distributed Generation program page for its requirements.

Permit Types, Fees, and Timelines by Major Arizona Jurisdiction

Fees are estimates based on publicly available schedules and change annually. Verify current fees directly with your AHJ before budgeting. The City of Phoenix, City of Tucson, and Maricopa County each publish current fee schedules on their development services websites.

Permit fees in Arizona are commonly calculated as a percentage of project valuation or on a flat-rate schedule tied to system size. The cost for a 6–10 kW residential system can range from under $100 to several hundred dollars. Contact your AHJ's development services department for a current fee estimate.

SolarAPP+ Participation

SolarAPP+ is an automated permit review tool from the National Renewable Energy Laboratory (NREL) that can issue permits in minutes for qualifying systems. Phoenix has adopted SolarAPP+, which significantly reduces plan review time for standard residential rooftop systems. Check the current participating jurisdiction list at solarapp.nrel.gov, as adoption is expanding.

Unincorporated county land, such as areas under Maricopa or Pima County jurisdiction, may have different requirements than incorporated cities, but a permit is still required. County development services departments enforce building and electrical codes on unincorporated parcels.

Step-by-Step: The Arizona Solar Permit Process

Step 1: System Design and Document Preparation

Your installer must prepare:

• A site plan showing roof layout, panel placement, and setbacks.
• A single-line electrical diagram showing the PV array, inverters, disconnects, and utility interconnection point.
• Equipment specification sheets for panels, inverters, and racking.
• Structural calculations or a stamped engineer's letter if the roof requires load analysis.
• Load calculation documentation for the service panel.

Fire setback requirements under the locally amended International Fire Code (IFC) affect panel placement. The designer must account for ridge, hip, valley, and eave setbacks.

Step 2: Submit Permit Application to Your AHJ

Most Arizona cities accept online submittals. If your jurisdiction uses SolarAPP+, the automated review can issue a permit within minutes for qualifying systems. The building and electrical permit applications should be submitted simultaneously.

Step 3: Plan Review

Plan reviewers check for:

• Structural adequacy of the roof and racking attachment.
• NEC Article 690 compliance (wiring, disconnects, rapid shutdown, labeling).
• Fire setback compliance per local IFC amendments.
• Utility service panel capacity.

Reviewer comments are a common source of delay and require the installer to respond and resubmit.

Step 4: Permit Issuance and Job Site Posting

The approved permit must be posted visibly at the job site during installation. Keep a copy of the approved plans on site for inspectors.

Step 5: Installation by ROC-Licensed Contractor

All work must be performed by or under the supervision of an ROC-licensed contractor (A-17 or C-11). Homeowners who pull their own permits become the legal contractor of record, which can void warranties and complicate future home sales.

Step 6: Schedule and Pass Inspection

After installation, schedule an inspection with your AHJ. The inspector will verify that the installation matches the approved plans and meets code, including:

• Racking attachment to structural members.
• Conductor sizing and wiring methods.
• Rapid shutdown compliance.
• Disconnect labeling and location.
• Grounding and bonding.

Failed inspections require corrections and a re-inspection.

Step 7: Utility Interconnection Application

Submit the interconnection application to your utility (APS, SRP, TEP) as early as possible, ideally at the same time as the permit application. The APS Distributed Energy Resources Interconnection Handbook and SRP's Distributed Generation program documentation outline requirements. For APS and TEP, interconnection standards are governed by Arizona Administrative Code R14-2-2301 through R14-2-2308.

Step 8: Utility Inspection and Meter Work

After your local inspection passes, the utility may schedule its own inspection and install a new bidirectional meter.

Step 9: Permission to Operate (PTO)

The utility issues PTO after it completes its review and any necessary meter work. You can only energize the system and export to the grid after receiving PTO.

Common Reasons for Rejection or Inspection Failure

• Incomplete single-line diagram or missing equipment spec sheets.
• Rapid shutdown labeling errors.
• Racking attached to roof sheathing instead of structural members.
• Panel placement violating IFC fire setbacks.
• Service panel at capacity with no documented upgrade plan.
• Installer not holding a valid ROC license.

What Changed Recently: 2025–2026 Arizona Solar Regulatory Updates

HB 2339: Solar Sellers and Marketers Licensure

HB 2339 (57th Legislature, 2nd Regular Session) proposes new licensure requirements for solar device sellers and marketers. As of March 18, 2026, the bill's latest action was House Second Reading and it had not been signed into law (OpenStates). If enacted, it would require individuals who sell or market solar devices to hold a state license. Verify the current status of HB 2339 at openstates.org/az/bills/57th-2nd-regular/HB2339/.

HB 2269: TPT Exemption for Utilities (Withdrawn)

HB 2269, which proposed changes to the transaction privilege tax (TPT) exemption for utilities, was withdrawn (per OpenStates). No change to TPT treatment of solar installations resulted from this bill.

SB 1430: Tax Corrections Act of 2026

SB 1430 (Tax Corrections Act of 2026) was signed by the Governor on April 14, 2026 (OpenStates). The available source material does not detail the bill's specific provisions. To confirm whether any provisions affect solar equipment TPT exemptions or tax credits, consult the Arizona Department of Revenue or review the enrolled bill text at openstates.org/az/bills/57th-2nd-regular/SB1430/.

Arizona Corporation Commission Net Metering Proceedings

The ACC has ongoing docket activity affecting net metering compensation rates for APS, TEP, and UniSource customers. For current compensation rates, consult the ACC at azcc.gov or search its docket management system for proceedings related to Docket No. E-01345A-13-0248 and any successor dockets.

NEC Edition Updates

While Arizona's statewide baseline is NEC 2017, individual jurisdictions may have adopted NEC 2020. Confirm with your AHJ which edition governs your project, particularly for Article 690 rapid shutdown requirements.

HOA Rules, Deed Restrictions, and Solar Rights in Arizona

What HOAs Can and Cannot Do

Under A.R.S. § 33-1816, an HOA cannot enforce any rule or CC&R provision that effectively prohibits a homeowner from installing a solar energy device.

An HOA may impose restrictions on placement and aesthetics, but those restrictions are unenforceable if they:

• Increase the system's cost by more than 10% compared to the owner's preferred design, or
• Decrease the system's efficiency by more than 10% compared to the owner's preferred placement.

Deed restrictions are subject to the same limits.

The HOA Approval Process

Most HOAs require submission of installation plans to an architectural review committee (ARC) for approval before work begins. Get this approval in writing before your installer pulls permits to avoid potential disputes.

If Your HOA Denies Your Application

If an HOA denies a solar application or imposes restrictions that violate the 10% thresholds, you can:

• Request a written explanation and cite A.R.S. § 33-1816.
• Escalate to the HOA board with documentation showing the cost or efficiency impact.
• File a complaint with the Arizona Department of Fire, Building and Life Safety.
• Pursue civil action in Arizona Superior Court.

The ACC Consumer Services division (azcc.gov) can assist with complaints involving solar contractors or utilities, but the Arizona Attorney General's Office does not mediate HOA disputes.

Pre-Application Checklist

Gather these items before your installer submits the permit application:

• Property survey or plot plan.
• Roof age and condition documentation.
• Recent utility bill.
• Written HOA approval letter, if applicable.
• Installer's ROC license number and insurance certificates.
• Signed interconnection application for your utility.
