What Distance Should Generators Be From a Home?

April 5, 2026

Quick Answer

Generators should be at least 20 feet away from a home to minimize the risk of carbon monoxide poisoning from fumes leaking into living spaces.

Proper Generator Placement

When placing a generator outside, choose a well-ventilated area away from any windows, doors, or vents. This distance will help prevent carbon monoxide from entering your home, reducing the risk of poisoning. A 20-foot radius is a general guideline, but this can vary depending on the size and type of generator.

Factors Affecting Generator Placement

The size and type of generator will influence the required distance from your home. For example, a portable generator producing 2-5 kilowatts may require a 15-foot clearance, while a larger, stationary generator can safely operate at a 20-foot distance with proper installation and maintenance. Additionally, wind direction and speed can impact the spread of carbon monoxide, so it’s essential to consider these factors when selecting a location.

Safety Precautions and Maintenance

To further minimize the risk of carbon monoxide poisoning, ensure your generator is properly maintained, including regular cleaning and servicing. Also, install carbon monoxide detectors in your home, ideally near sleeping areas, to provide an early warning system in case of a leak. By following these guidelines and taking necessary precautions, you can create a safer environment for your family and reduce the risk of carbon monoxide poisoning.
