What does getPermit actually do?

getPermit reads your job details and tells you what a California city expects before you file: which permits the work triggers, the documents and plans you'll need, the fees to budget for, and the common reasons applications in that jurisdiction get bounced back. It produces a clear checklist you can act on. It does not submit to the city for you — you (or your permit person) stay in control of what gets filed.

Is there a human involved, or is it just AI?

Both. The AI does the research and drafts the assessment and checklist; an experienced permit coordinator reviews and approves it before it's treated as authoritative. The human check is the point — it's how we keep it trustworthy in a process where a wrong filing has real consequences.

Which cities do you cover?

We're starting deep in California rather than shallow everywhere. For a city we haven't fully mapped yet, we'll give you accurate general California guidance and point you to that city's official building department — and you can join the waitlist to be notified when we cover it in depth. We will not invent city-specific fees or timelines we haven't verified.

Solo electricians, plumbers, and HVAC contractors, and small general contractors who don't have a dedicated permit department and lose billable hours to permit admin.

How much does it cost?

It's pre-launch. Join the waitlist and you'll get founder pricing, your jurisdiction prioritized, and a direct line to the team. No spam, no credit card.

Battery storage permits in Arizona

Last updated September 13, 2026

Early Arizona guides. getPermit is California-first — these pages share what we've verified in Arizona so far, and they don't mean getPermit covers Arizona yet. Join the waitlist with your city to tell us where to go deeper.

A plain-English starting point for electrical contractors. This is general Arizona guidance — fees, forms, and timelines are set by each city.

Short answer

Home battery storage needs a permit in the Phoenix-area jurisdictions that address it: Phoenix requires a Planning & Development permit plus a Phoenix Fire permit for energy storage systems, and Mesa requires a Development Services permit for any solar system that includes a battery. Batteries also take a system out of Phoenix's SolarAPP+ path. The work is done by an ROC-licensed electrical contractor.

The general picture

Battery storage is newer territory for many Arizona building departments, and guidance is uneven. Phoenix requires a Planning & Development permit plus a Phoenix Fire permit for energy storage systems, and its SolarAPP+ path excludes batteries. Mesa requires a Development Services permit whenever a solar system includes a battery. We didn't find standalone battery guidance from Scottsdale or unincorporated Maricopa County, so confirm the permit path before you quote. Utilities add their own equipment rules — SRP requires UL 1973 batteries and UL 9540 systems. See the verified notes for Phoenix and Mesa.

Typically needs a permit

In Phoenix, every energy storage system needs a Planning & Development permit and a Phoenix Fire permit; in Mesa, any solar system that includes a battery needs a Development Services permit. Panel, service, or transfer equipment changes that come with a battery typically need permits too.

Usually doesn't (general norm)

Portable power stations that plug into outlets

Documents & plans generally required

Electrical permit application, plus a fire permit application where the city requires one
ROC license number and class
Battery and system cut sheets showing their safety listings
One-line diagram with the battery, inverter, disconnects, and backup loads panel
Location plan showing where the battery is installed and its clearances
Utility interconnection application if the battery can operate in parallel with the grid

Common reasons battery storage applications get bounced

Code-rooted patterns across Arizona — not a city-specific rejection rate.

Battery and system listings not documented
Installation location doesn't meet the adopted residential code's energy storage requirements
Backup loads panel or transfer equipment missing from the one-line diagram
Submitted through a fast-track path that excludes batteries
Fire department permit not obtained where the city requires one

The inspection sequence

A typical order — the number of stops and exact sequence vary by jurisdiction and scope.

1Electrical rough inspection when conduit or wiring will be concealed
2Final building or electrical inspection, plus a fire inspection where required
3Utility approval before the system operates in parallel with the grid

Licensing — who can pull it

Battery storage in Arizona is installed by an ROC-licensed electrical contractor — R-11, CR-11, or C-11. SRP requires UL 1973 listed batteries and UL 9540 listed systems.

Frequently asked questions

Do I need a permit for a home battery in Arizona?

In Phoenix and Mesa, yes. Phoenix requires a Planning & Development permit and a Phoenix Fire permit for energy storage; Mesa requires a Development Services permit when a solar system includes a battery. We didn't find standalone battery guidance from Scottsdale or unincorporated Maricopa County, so confirm the path before quoting.

Can I add a battery through SolarAPP+ in Phoenix?

No. Phoenix's SolarAPP+ path excludes battery storage, so a system with a battery goes through the City's other permit process.

What equipment listings do utilities require?

SRP requires UL 1973 listed batteries and UL 9540 listed energy storage systems. Check your utility's interconnection requirements before ordering equipment.
