About Battery Permit Guide

What This Site Is
Battery Permit Guide is an independent informational resource covering home battery storage permit requirements for all 50 U.S. states. We publish plain-English guides, free tools, and printable checklists to help homeowners understand what's required before installing a Powerwall, Enphase IQ Battery, or any other residential energy storage system.
Home battery installations are becoming increasingly common as electricity prices rise, grid outages increase, and solar adoption grows. But the permit process is genuinely confusing: there's no national standard, every city and county sets its own rules, and requirements change as codes are updated. Most of the information online is either too generic ("yes, you need a permit") or buried in government PDFs that are hard to find and harder to read.
We built this site to fill that gap — one clear, state-by-state guide at a time.
Our Editorial Approach
Every page on Battery Permit Guide is written to answer a specific question that a real homeowner is searching for. Our standards for each page:
- Specificity over generality. "You need a permit" is not useful. "Austin requires an electrical permit filed through Austin Build + Connect with a 3–4 week review time" is useful. We aim for the latter.
- One concrete detail per page that isn't easily found elsewhere. This might be a specific city fee, a recent code change, a brand-specific documentation requirement, or a procedural nuance that trips people up.
- Honest about uncertainty. Permit requirements change. When we're not certain a specific detail is current, we say so and direct you to verify with the relevant authority.
- No paid placements. We don't accept payment from installers, battery brands, or permit services to recommend their products or services. Our tools and guides reflect requirements as we understand them, not as advertisers want them presented.
How We Make Money
Battery Permit Guide is supported by Google AdSense display advertising. Ads appear on pages across the site. We have no affiliation with any battery manufacturer, installer, or permit service. Advertisers do not influence our editorial content.
Accuracy and Updates
Permit requirements, fee schedules, and building codes change regularly. We update our state guides and content on a rolling basis as we become aware of changes. However, we cannot guarantee that every piece of information on this site reflects the most current requirements in every jurisdiction.
Always verify permit requirements with your local building department before submitting a permit application or starting any installation. This site is a starting point, not a substitute for direct confirmation from your Authority Having Jurisdiction (AHJ).
