All energy storage systems (ESS) shall comply with the applicable provisions of the California Residential code R328, California Electrical Code 706 and all other applicable codes.
Find out about options for residential energy storage system siting, size limits, fire detection options, and vehicle impact protections.
The following list is not comprehensive but highlights important NFPA 855 requirements for residential energy storage systems. In particular, ESS spacing, unit capacity limitations, and maximum
This tip sheet reflects code requirements for the installation of energy storage systems, also could be known as a power wall or battery storage systems, under the 2021 International Residential Code
NFPA 855 provides detailed, prescriptive requirements for how and where energy storage systems can be installed. Adhering to these guidelines is crucial for compliance and safety.
ESS can be installed in any of those locations, however if the room is unfinished, the walls and ceiling need to be protected by at least 5/8 in. (16 mm) gypsum board. Certain types of energy
While NFPA 855 is a standard and not a code, its provisions are enforced by NFPA 1, Fire Code, in which Chapter 52 outlines requirements, along with references to specific sections in NFPA 855.
Siting and Size LimitsFire DetectionVehicle Impact ProtectionJoin The Storage Fire Detection Working GroupYou have four options for siting ESS in a residential setting: an enclosed utility closet, basement, storage or utility space within a dwelling unit with finished or noncombustible walls or ceilings; inside a garage or accessory structure; on the exterior wall of the home; and on ground mounts.
