Why Solar Makes Sense in Mesa, Arizona
Mesa is the third-largest city in Arizona and benefits from the same exceptional 299+ sunny days per year as the greater Phoenix metro, making it one of the top solar markets in the country. The City of Mesa Building Safety Division processes solar permits for Mesa. Most of Mesa is served by APS, while parts of the city fall within SRP territory. Chandler, a neighboring city, has its own permitting process.

In Mesa, AZ, solar permitting involves city building codes and utility interconnection. The City of Mesa oversees construction safety, while your utility provider, typically Salt River Project (SRP) or Mesa Electric, regulates grid connection.
1. City Permitting Requirements
Most residential solar installations in Mesa require a building permit to ensure structural and electrical safety.
- Permit Types:
- Roof-Mounted: Typically classified as a minor residential electrical permit.
- Ground-Mounted: Generally classified as a residential accessory permit.
- Exemptions: Systems under 10,000 square feet installed by a licensed contractor may not require a full construction permit, provided no major electrical panel changes are involved. A permit is always required for new meters or circuits.
- Online Portal: Applications and permit tracking are handled through the Mesa E-Permit Online Portal (DIMES).
- Fire Safety: Systems must follow roof layout requirements to maintain emergency access pathways for firefighters.
2. Utility Interconnection
Permission to Operate (PTO) from your utility provider is required before your system can go live.
- Mesa Electric Utility: Customers in the city-run utility area must submit plans, a utility bill, and a signed Customer Acknowledgement Document to the engineering group.
- SRP/APS: These providers maintain separate application portals with their own technical requirements for inverters and disconnect switches.
3. Contractor Selection
Mesa requires solar installers to hold specific license classifications such as C-11, B-05, or R-11.
- Verification: Contractor licenses can be confirmed through the Arizona Registrar of Contractors (ROC).
- Incentives: Licensed installers will automatically apply the Arizona Solar and Wind Sales Tax Exemption, saving you 5.6% on equipment costs.

Mesa solar permit fees
Solar permitting in Mesa, AZ, is relatively straightforward. The city often does not require a building permit for residential solar systems that leave the main electrical service panel unchanged. When electrical permits are needed, costs generally range from $200 to $1,500, with $300 being a common benchmark for comparable projects in the area.
Key Solar Permitting and Cost Details in Mesa:
- Permit Exemption: Mesa, along with neighboring Gilbert, waives the building permit requirement for residential rooftop systems that do not alter the main service panel. This exemption extends to certain commercial, roof-mounted, and parking canopy installations.
- Safety Requirements: Even when formal permits are not required, all solar installations must comply with firefighter safety regulations governing roof access and setbacks.
- Utility Fees: City permit costs may be minimal, but utility providers typically require a Notice to Proceed and may charge grid connection fees. A switch to time-of-use (TOU) rates is also commonly required.
- Cost Factors: When a permit is required, the total cost depends on system size, installation type (ground-mounted vs. roof-mounted), and whether a structural engineering report is necessary.
