Home battery HOA approval: what to submit and what the law says

A home battery in a community with a homeowners association can need two approvals: the building department's permit, which applies the fire and electrical codes, and the association's architectural review, which applies its own guidelines. In the published HOA guideline quoted below, the committee's requests are about location and appearance, and most of the answers can be drawn from the permit set and the manufacturer's datasheet.

The first half of this page is the application, built from one published set of HOA guidelines, one state statute that lists required contents, and one city permit guide. The second is the law. We read the HOA solar statutes of nine states on official legislature or statute sites, a set we picked rather than a survey of every state, and recorded whether each text covers energy storage or batteries, or only solar collectors. Every quote was read on October 19, 2026. This is a reading of published text, not legal advice; your governing documents and a lawyer licensed in your state are the authorities on your situation.

What a published HOA guideline asks for

The Residential Improvement Guidelines for Solterra, a community in Lakewood, Colorado, revised April 2026, mention batteries by name. Section 3.57, titled "Utility Equipment, Generators, and Powerwalls", states that "Approval is required for installation of generators, Powerwalls, or backup battery power units installed on the exterior of the home." It then lists what has to come with the request: the location "must be indicated on an official plat", and "A diagram of the layout of any components, the dimensions, and a photo of the proposed location are required." The section opens: "Approval is required for installation of utilities or utility equipment, including but not limited to all exterior pipes, conduits, generators, Powerwalls, and other equipment. Utility facilities must be kept and maintained, to the extent possible, underground or within an enclosed structure." It adds that "Adequate screening may also be required." Its solar section, 3.52, points battery owners back to 3.57 for "Powerwalls and battery storage units installed on the exterior of the home." (read October 19, 2026)

That is one community, not a national pattern, and we do not know what most HOAs require. Every item it asks for is a document that exists before installation day.

Michigan is the one state we read that writes the contents of an application into law. Under the Homeowners' Energy Policy Act, MCL 559.311, a member installing a solar energy system submits a written application with the member's name, the street address, "The name and contact information of the person that will install the solar energy system", "An image that shows the layout of the solar energy system on the member's home or unit", and a description of the system (read October 19, 2026). As covered below, Michigan's definition of a solar energy system includes batteries that store solar energy.

The documents that answer those questions

Each item below is a document you can get from your installer, the manufacturer, or the building department. The first three cover what Solterra's section 3.57 asks for; the rest come from the permit process.

• Site plan or plat with the battery location marked, plus a component layout. Solterra asks for the official plat and a diagram of the layout of any components. The City of Palo Alto's residential ESS permit guide asks for a site plan that will "Identify location of proposed ESS", so one drawing can serve both reviews (read October 19, 2026). The guide's header cites the 2019 California codes, so treat it as one city's checklist rather than a current code summary.
• A photo or elevation of the proposed wall. Palo Alto asks for elevation plans if the ESS is installed outside, "to indicate location relative to doors, windows, gas meter, etc."
• The manufacturer datasheet. Solterra asks for dimensions, and the datasheet publishes them, along with the enclosure rating and noise figure a neighbor or committee may raise. The Tesla Powerwall 3 datasheet, for example, lists dimensions of 43.5 x 24 x 7.6 in, "Indoor and outdoor rated", an enclosure rating of NEMA 3R, and operating noise at 1 m of under 50 dB(A) typical and under 62 dB(A) maximum (read October 19, 2026). Other models: dimensions, noise, outdoor ratings.
• The UL 9540 listing. The Powerwall 3 datasheet lists UL 9540 in its Certifications row. Palo Alto's guide states "ESS shall be listed and labeled in accordance with UL 9540." Ask for the listing of the exact assembled system on your quote; what that standard does and does not certify is in our UL 9540 and NFPA 855 guide.
• The installer's name and contact details. Michigan requires the installer's name and contact information on a solar application.
• The building permit or the permit set. Fire code review belongs to the permitting authority, not the HOA. Our installation guide covers that sequence.

The location rules a committee will see on the plan

The 2024 International Residential Code, Chapter 3, published by the International Code Council, permits ESS in detached garages and detached accessory structures, attached garages separated from the living space, "Enclosed utility closets, basements, storage or utility spaces within dwelling units with finished or noncombustible walls and ceilings," and "Outdoors or on the exterior side of exterior walls located not less than 3 feet (914 mm) from doors and windows directly entering the dwelling unit, except where smaller separation distances are permitted by the UL 9540 listing and manufacturer's installation instructions." It caps individual units at 20 kWh and the aggregate at 40 kWh in utility closets, basements, and storage or utility spaces, and 80 kWh in garages, on exterior walls, and outdoors on the ground. In the 2021 edition the energy storage section is R328, with listings at R328.2, locations at R328.4, and energy ratings at R328.5 (both read October 19, 2026).

NFPA's own summary of the residential chapter of NFPA 855 gives the same 3 ft distance and the same 40 kWh and 80 kWh limits (read October 19, 2026). Your jurisdiction adopts its own edition; the detail is in our location guide.

What nine state statutes say about batteries

The question for a battery is whether each statute's own definition reaches storage.

The four whose text reaches storage

Illinois. The Homeowners' Energy Policy Statement Act defines a "Solar storage mechanism" as equipment or elements, listing "batteries" among them, "that are utilized for storing solar energy, gathered by a solar collector, for subsequent use." A "Solar energy system" is a solar collector "or a solar storage mechanism". Section 15 bars an association from any bylaw or power that "prohibits or has the effect of prohibiting the installation of a solar energy system." Section 30 sets 30 days to process an application, and section 45 excludes buildings over 60 feet tall and shared roofs.

Michigan. Act 68 of 2024, effective April 2, 2025, uses nearly the same wording: a solar storage mechanism includes "batteries" used "for storing solar energy gathered by a solar collector for subsequent use", and a provision that "prohibits or has the effect of prohibiting the installation of a solar energy system is invalid and unenforceable." A bill to repeal the act, House Bill 4363 of 2025, was re-referred to the Committee on Energy on October 21, 2025, and the bill page shows no later action.

Arizona. A.R.S. 33-1816 states that an association "shall not prohibit the installation or use of a solar energy device as defined in section 44-1761"; it sits in Chapter 16, Planned Communities, so by its placement it addresses planned community associations; Arizona's condominium law is Chapter 9. Section 33-439 voids deed covenants that do the same, except instruments "entered into before April 17, 1980". The definition in 44-1761 is the broadest we read. A solar energy device "Includes a distributed energy generation system", which "Means a device or system that is used to generate or store electricity" with a capacity "greater than one kilowatt or one kilowatt-hour" that is "primarily for on-site energy consumption." It excludes "an electric generator that is intended for occasional use." Associations may still adopt "reasonable rules regarding the placement" that do not impair the device or adversely affect its cost or efficiency.

Texas. Property Code 202.010 bars a property owners' association from prohibiting or restricting a "solar energy device", which takes its meaning from Tax Code 171.107: "The term includes a mechanical or chemical device that has the ability to store solar-generated energy for use in heating or cooling or in the production of power." The location exceptions are the part to read for a battery. An association may prohibit a device located anywhere other than "on the roof of the home or of another structure allowed under a dedicatory instrument" or "in a fenced yard or patio owned and maintained by the property owner", and one in a fenced yard that "is taller than the fence line." A side-wall battery outside a fence sits in that gap. The section also keeps the approval step, since an association may prohibit a device that "was installed without prior approval", and during the development period of a development with fewer than 51 planned residential units, the declarant "may prohibit or restrict" solar energy devices. Section 202.019, the standby generator section, is limited to devices "powered by natural gas, liquefied petroleum gas, diesel fuel, biodiesel fuel, or hydrogen", so it does not reach batteries, and Chapter 202 contains no battery section as published.

The two that say "storage" of solar energy

California. Civil Code 714 voids governing document provisions that "effectively prohibits or restricts the installation or use of a solar energy system", allows reasonable restrictions that do not add more than $1,000 to a photovoltaic system's cost or cut its efficiency by more than 10 percent, and deems an association application approved if not denied in writing within 45 days. Its definition comes from Civil Code 801.5: "Any solar collector or other solar energy device whose primary purpose is to provide for the collection, storage, and distribution of solar energy". The word "storage" is there; batteries are not named, and the text does not say whether a battery is a "solar energy device" in its own right. Civil Code 4746 applies only to solar on a multifamily common area roof, requires notice to each owner in the building and liability insurance, and does not mention storage.

Maryland. Real Property 2-119 defines a "Solar collector system" as "a solar collector or other solar energy device, the primary purpose of which is to provide for the collection, storage, and distribution of solar energy". Its protection is narrower than the definition: a restriction may not impose unreasonable limitations on installation "on the roof or exterior walls of improvements", with unreasonable meaning at least 5 percent added to cost or at least 10 percent lost from generation. Batteries are not named.

The three that are silent

Colorado. C.R.S. 38-30-168 voids covenants against a "renewable energy generation device", defined as a solar energy device, a wind-electric generator, a geothermal energy device, or a heat pump system. The solar energy device definition in 38-32.5-100.3 is a device that "provides for the collection of sunlight" as part of a system converting it to energy. Storage is not mentioned. Inside common interest communities, 38-33.3-106.5 says an association "shall not effectively prohibit renewable energy generation devices, as defined in section 38-30-168", and 38-30-168 deems an application approved after 60 days. Solterra, a Colorado community, files Powerwalls under utility equipment rather than under solar energy devices.

Florida. Section 163.04 of the 2026 Florida Statutes bars covenants that prohibit "solar collectors, clotheslines, or other energy devices based on renewable resources from being installed on buildings", and adds: "A property owner may not be denied permission to install solar collectors or other energy devices by any entity granted the power or right in any deed restriction, covenant, declaration, or similar binding agreement to approve, forbid, control, or direct alteration of property". Neither sentence mentions storage or batteries, and the text does not define "other energy devices".

Virginia. Code 55.1-1820.1 covers a "solar energy collection device", meaning "any device manufactured and sold for the sole purpose of facilitating the collection and beneficial use of solar energy, including passive heating panels or building components and solar photovoltaic apparatus." It is silent on storage, and it lets the recorded declaration establish a prohibition.

What the statutes leave open

Three questions the texts do not settle.

A battery with no solar. Illinois and Michigan tie storage to energy "gathered by a solar collector", and Texas to "solar-generated energy." A grid-charged battery on a house with no panels is not obviously inside any of those words. Arizona's distributed energy generation wording, which its solar energy device definition includes, does not mention solar on its face. For a battery without solar, whether any of these texts applies is a question for your documents and a lawyer.

Location. Every statute we read leaves the association some room for placement or design rules, and several exclude common areas outright. Texas allows a prohibition on devices outside the roof or a fenced yard. Maryland's protection runs to roofs and exterior walls. Solterra's battery rule is written for units "installed on the exterior of the home"; another association's rule may be worded differently.

Deadlines. The approval clocks in California, Colorado, Illinois and Michigan are written for solar energy systems as each law defines them. A committee that treats your battery as ordinary utility equipment may not see itself as bound by them.

Putting the application together

The documents in this guide are easiest to assemble once the installer has settled the location against the code and the datasheet: the marked plat or site plan, a photo of the wall, the datasheet, the UL 9540 listing, the installer's license, and the permit set. An application can cite the section where a statute's definition names storage; whether it applies to your battery is a question for your documents and a lawyer.
