Residential battery projects must follow the applicable local permit, inspection, electrical, fire-code and utility requirements for the address and system design. HUS coordinates contractor-side plan documents, permit submissions, inspection scheduling and utility steps where they are part of the written project scope. Program eligibility and property-disclosure consequences depend on current rules and project records.

Battery permits are issued by the local building authority for the address where the system is installed — not a statewide agency. In a region as large as LA and OC, that means many different permitting authorities.
The exact responsibility depends on the signed scope, jurisdiction and utility path. For qualifying battery projects, contractor-side coordination may include:
Permit issuance, inspection results, utility authorization and final approval remain with the responsible agencies.

Residential battery storage installations generally require permit and inspection review by the applicable local authority, with the exact permit type and plan-check path depending on the jurisdiction and project scope. In the City of Los Angeles, LADBS handles applicable building and electrical permit review. Other LA and Orange County cities use their own building departments. HUS coordinates the permit responsibilities identified in the written battery-project scope.
The required inspection sequence depends on the jurisdiction and approved permit scope. Review commonly includes electrical installation, equipment mounting, clearances, labeling and other code items, and some projects can involve additional fire-code or agency review. HUS coordinates the inspection responsibilities identified in the written scope, while final approval remains with the authority having jurisdiction.
If a battery project is pursuing an available SGIP pathway, the current program handbook and administrator process can require installation, inspection, equipment and closeout documentation. Eligibility also depends on the active budget category, funding, utility territory, equipment, project timing and other program rules. HUS can organize contractor-side closeout documentation for review where an active pathway applies, but program approval and funding remain with the administrator.
Utility requirements depend on the serving utility and system configuration. SCE currently states that storage not paired with a NEM generator must be submitted as a Rule 21 Non-Export project, while storage paired with an eligible solar generator follows the applicable customer-generation interconnection process. LADWP and municipal utilities have separate rules. We confirm the utility account and required interconnection path during project planning.
Permit and plan-check timing varies by jurisdiction, submission path, project complexity, correction cycles and agency workload. HUS accounts for the permit path in project scheduling and coordinates submission and follow-up responsibilities identified in the written scope, but city review and final approval timing are controlled by the authority having jurisdiction.
Residential energy storage systems are subject to the applicable California Fire Code, California Electrical Code, manufacturer listing and local amendments. The 2025 California Fire Code addresses residential ESS in Section 1207.11 and references NFPA 855 where applicable. Exact location, spacing, capacity, protection and labeling requirements depend on the system and installation conditions. HUS reviews those requirements for the approved project scope.
Many battery projects require electrical drawings such as a single-line diagram, equipment information and site or placement details, but the exact plan-set and signature requirements vary by jurisdiction and project scope. HUS prepares or coordinates the contractor-side documentation identified in the written scope and submits it through the applicable permit path where required.
