About GeneratorPermitGuide
Why This Site Exists
When a homeowner decides to install a standby generator, they quickly discover a frustrating problem: the permit information they need is scattered across dozens of county building department websites, manufacturer installation manuals, and state code documents — none of which are written for a layperson trying to understand what they actually need to do.
Contractors don't always explain the permit process. Some skip permits entirely. And a generator installation done without proper permits can result in fines, insurance denial, and serious problems when the home is sold. The consequences of not understanding the rules are real and expensive.
GeneratorPermitGuide was built to solve this information gap. Our goal is simple: give homeowners a clear, accurate, jargon-free reference for generator permit requirements before they spend $8,000–$15,000 on an installation.
