Battery storage permits in Long Beach, CA
General California guidance last updated August 2, 2026 · Long Beach data verified August 10, 2026
What electrical contractors need to know about pulling a battery storage permit in Long Beach (Los Angeles County).
Short answer
In California, installing a home or small-commercial battery energy storage system (ESS) requires an electrical permit — and residential installs are reviewed against the ESS location and clearance rules in the California Residential Code (R328) and Fire Code. The system must carry a UL 9540 listing, and the utility interconnection is a separate, parallel process. A C-10 (Electrical) or C-46 (Solar) licensed contractor generally pulls it.
Long Beach accepts submittal through the LB Services — Permitting and Licensing and has adopted the 2025 California Building Standards Code (with the Long Beach Municipal Code). Fee details and sources are below.

The general picture in California
An ESS install is permitted electrical work throughout California, and the review is layered: the California Electrical Code (Title 24, Part 3 — Article 706 for storage, 705 for the interconnection, 690 where solar is paired), the residential ESS rules in CRC R328 with their location, clearance, and energy limits, fire-code provisions for larger systems, and the UL 9540 listing requirement that ties it together. Most corrections come from placement — where the battery sits and what it is near — and from listing documentation, not from the wiring itself. State law has pushed cities toward instant online permitting for residential solar-plus-storage, so many jurisdictions route these permits through SolarAPP+. The utility side is separate: interconnection (Rule 21 at the investor-owned utilities) runs in parallel with the city permit, and the system operates in parallel with the grid only after permission-to-operate. Fees, fire-review thresholds, and submittal format are set per city — confirm with the local building department.

Typically needs a permit
Battery storage itself triggers a permit in nearly every California jurisdiction, Long Beach included. Long Beach-specific variations are confirmed with the issuing department above.
Usually doesn't (general norm)
- Portable plug-in power stations that aren't permanently wired to the building
- The utility interconnection application itself — required, but it's a utility process, not the city permit
- Monitoring or communications changes on an existing permitted system
Documents & plans generally required
- Electrical permit application — many California cities process residential solar-plus-storage through SolarAPP+
- Contractor license and city business registration
- Single-line diagram: battery, inverter, disconnects, OCPD ratings, and the interconnection point (whole-home backup vs. backup-loads panel vs. grid-tied only)
- Equipment cut sheets with the UL 9540 listing (and UL 9540A fire-test data where the AHJ requests it)
- Site/floor plan showing the ESS location, mounting, and clearances from doors, windows, and egress paths
- Busbar/backfeed check at the panel (the 120% rule) or a supply-side connection detail
- Load calculation for a backup-loads panel
- Labeling plan — disconnects, rapid shutdown where solar-paired, and emergency-responder signage
Common reasons battery storage applications get bounced
Code-rooted patterns across California — not a Long Beach-specific rejection rate.
- Location not allowed under CRC R328 — habitable rooms, or clearances to openings and egress not met
- Missing or wrong listing — the system isn't documented as UL 9540 (a UL 1973 battery module alone is not a listed ESS)
- Single-line diagram inconsistent with the cut sheets, or missing disconnect and OCPD ratings
- 120% rule violation at the panel without a main-breaker derate or supply-side connection
- A backup-loads panel proposed without a load calculation
- Per-unit or aggregate energy limits for the location exceeded without the additional protections R328 requires
- No labeling/signage plan — placards are verified at final
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Rough inspection if any wiring or conduit is concealed before cover
- 2Final inspection: mounting, clearances, disconnects, labeling, and shutdown function verified — some jurisdictions add a separate fire-department review or inspection
- 3Utility permission-to-operate (PTO) after city sign-off — the system generally can't operate in parallel with the grid until PTO
Licensing — who can pull it
Battery storage in California is generally installed by a C-10 (Electrical) licensed contractor; a C-46 (Solar) contractor may install ESS as part of a solar energy system. A B (General Building) contractor may pull within a larger project under CSLB rules. The installing contractor typically also files the utility interconnection.

Frequently asked questions
Do I need a permit to add a battery to an existing solar system?
Yes — a storage retrofit is its own electrical permit even when the PV system is already permitted. It changes the interconnection, adds NEC Article 706 scope (disconnects, listing, signage), and brings the residential ESS location and clearance rules (CRC R328) into review.
Where can a residential battery be installed?
CRC R328 restricts ESS to specific locations — typically garages, detached or accessory structures, outdoors with clearance from doors and windows, or dedicated utility spaces — with per-unit and aggregate energy limits that vary by location. Habitable rooms are off the table. Placement and clearances are the most common plan-check correction, so settle the location before finalizing the design.
What listing does the equipment need?
The ESS as a system needs a UL 9540 listing; UL 9540A is the fire-propagation test data an AHJ may request for larger installs or reduced spacing. A battery module's UL 1973 listing alone doesn't make it a listed ESS — pairing an unlisted battery with a separate inverter is a recurring rejection.
Does the city permit cover exporting to the grid?
No — parallel operation and export run through the utility's interconnection process (Rule 21 for the investor-owned utilities; municipal utilities have their own). The city permit and the utility application proceed in parallel, and the system needs the utility's permission-to-operate before it runs in parallel with the grid.
