The rules can vary widely depending on where you live, and non-compliance can result in fines or even voided warranties.
In this comprehensive guide, we’ll explain the general permit requirements for installing home generators, provide examples from several popular cities, and offer practical tips to ensure your installation meets local regulations. Whether you’re in a major metropolitan area or a suburban community, knowing when you need a permit can save you time and money.
