Are there legal restrictions on dual-fuel generator use in certain states?

April 5, 2026

Quick Answer

Yes, some states have regulations on dual-fuel generator use, particularly concerning emissions and noise pollution. California, for instance, has specific guidelines for generator usage. Homeowners should research local laws before purchasing a dual-fuel generator.

State Regulations and Emissions

In the United States, each state has its own set of regulations regarding generator usage. Dual-fuel generators, which run on both gasoline and propane, are subject to these rules. California, for example, has a strict emissions policy, which restricts the sale and use of generators not meeting its emission standards. As of 2020, California’s South Coast Air Quality Management District (SCAQMD) Rule 1146.2 dictates that all generators with a rating of 2.0 kW or higher must meet specific emission standards. Homeowners in California should ensure their dual-fuel generator meets these requirements before purchasing.

Noise Pollution and Local Ordinances

In addition to emissions regulations, some states have noise pollution laws governing generator usage. Homeowners should check local ordinances regarding generator noise levels, as some areas may have specific restrictions. For instance, the city of New York has noise regulations for generators, requiring them to be at least 10 feet away from property lines. Homeowners should research local noise ordinances before installing a dual-fuel generator.

Choosing a Generator that Meets State Regulations

When selecting a dual-fuel generator, homeowners should research the model’s compliance with state regulations. Some generators, such as those from Generac, offer a range of models meeting California’s emission standards. Homeowners should consult with the manufacturer or a certified dealer to ensure the chosen generator meets all applicable state regulations. Additionally, homeowners should always follow local guidelines for generator installation and usage to avoid potential fines or penalties.
