When you’re planning to install a standby generator at your home, one of the crucial factors to consider is the distance between the generator and your house. Proper placement is essential for safety, noise reduction, and compliance with local building codes.
You may be wondering, how far should a standby generator be from your house? Generally, it’s recommended that a standby generator be at least 5 feet away from the nearest part of your home, while some sources suggest 18 to 20 feet, depending on various factors such as local codes and noise requirements.
It’s also important to have the generator at least 5 feet from any windows or doors to prevent dangerous fumes from entering your home.
With these guidelines in mind, make sure to check your local building codes and requirements before you finalize the location for your standby generator. Proper placement ensures your family’s safety and the generator’s optimal performance.

Determining the Appropriate Distance
NFPA 70 Generator Clearance
When placing a standby generator near your house, it’s crucial to adhere to the National Fire Protection Association (NFPA) 70 guidelines. According to these standards, a standby generator should be placed at least 18 inches away from the home and 5 feet away from doors and windows.
Generator Clearance Requirements
Considering the clearance requirements is essential to ensure your generator operates safely and efficiently. The general rule for a portable generator placement is to keep it at least 20 feet away from your home, with the engine exhaust facing away from the house to prevent fumes from entering.
Keep in mind that the final distance of your whole house generator from your home may vary based on specific factors such as:
- Local building codes
- Noise requirements
- Safety regulations
For instance, whole house generators must be installed at least 1.5 feet (18 inches) away from the house and 5 feet (60 inches) away from any windows or doors.
When placing a standby generator, it’s crucial to balance safety, efficiency, and local regulations. Always consult with your local authorities and a licensed electrician to ensure you adhere to proper guidelines and that your generator is installed safely and effectively.
Choosing the Ideal Generator Location
How Much Ventilation Does a Generator Need
When selecting a spot for your standby generator, ensure it has adequate ventilation. Generators produce exhaust fumes that can be hazardous if not properly vented. Place your generator at least 5 feet away from any doors, windows, or vents to prevent the buildup of dangerous gases.
Pro tip: It’s essential to maintain a clearance of at least three feet around the generator to avoid the risk of fire from flammable materials.
Possible Site Options
There are a few factors to consider when choosing the best location for your standby generator. Keep in mind local code requirements and manufacturer guidelines, as they may influence your decision.
- Distance from the house – For safety reasons, plan on placing the generator at least 18 inches away from your home. Local code authorities may have specific regulations, so it’s wise to consult with them before making a final decision.
- Away from vegetation – Position your generator away from any shrubs or vegetation over 12 inches in height. This can help reduce fire risks and ensure proper air circulation.
- Accessibility – Choose a location that facilitates easy access for regular maintenance and refueling. Make sure you can easily reach your generator during adverse weather conditions when you might need it the most.
Remember, selecting the perfect spot for your standby generator is crucial to ensure its optimal performance, safety, and longevity. Following these guidelines helps you confidently choose the ideal location for your generator, keeping your home safe and powered during unexpected outages.
Other Factors to Consider
When determining the ideal generator distance from house, there are a few other factors you should take into account, such as fuel type and storage, and noise reduction.
Fuel Type and Storage
The fuel type and storage for your standby generator play a role in its ideal placement. If you’re using a natural gas or propane-fueled generator, the fuel supply must be accessible, and the generator must be placed reasonably close to your gas meter. Keep in mind that additional piping may be necessary if your generator is too far from the gas meter, resulting in increased costs for supplies and labor.
For diesel generators, it’s essential to store the fuel properly, avoiding placing the fuel storage too close to your home or living area. Be sure to follow local regulations and safety guidelines for fuel storage.
Noise Reduction
Standby generators can produce a noticeable amount of noise, so noise reduction should be considered when deciding placement. Position your generator far enough away from your home to minimize the impact of the noise on your living environment.
One way to further reduce noise is by adding sound barriers or enclosures around your generator. These can help absorb and dampen sound waves, allowing you to enjoy your home in peace while your generator runs. Always ensure proper ventilation and air circulation for your generator, especially when using noise reduction measures.
Remember also to check your local noise regulations and guidelines to make sure your generator’s noise level complies with any specific requirements.
Frequently Asked Questions
Generator placement codes
Each locality may have its own set of codes and regulations governing the placement of standby generators. It’s important to consult with your local authorities or an electrician to ensure the proper installation and compliance with local laws. It’s also advised to check the manufacturer’s recommendations as specific generators may have different requirements.
Distance from house code
The general guideline for the distance between a standby generator and your house is 5 to 10 feet. However, this may vary depending on the type of generator, local codes, and other factors like noise, exhaust fumes, and vibration. Always follow local regulations and manufacturer recommendations for safe installation.
Required clearances
Clearances around your standby generator are crucial to ensure proper ventilation, reduce fire risks, and maintain safe access for maintenance. The generator should be placed on a level surface, at least three feet away from any building openings, such as doors and windows. Moreover, make sure to keep the surrounding area free of flammable materials like gasoline or propane.
Propane generator distance
The distance required for a propane generator may vary based on the specific generator and local regulations. Similar to other standby generators, it’s essential to maintain a clearance between your house and the generator. Consult your propane generator’s manual and local authorities to identify specific clearance requirements.
Transfer switch proximity
The transfer switch, which connects your standby generator to your home’s electrical system, should be installed by a qualified electrician in a safe and accessible location. The distance between the generator and the transfer switch will depend on the specific components and wiring used in the installation. Follow local codes and electrician recommendations to ensure safety and efficiency.
Generator near window
It is crucial not to install your standby generator too close to a window, as harmful exhaust fumes may enter your home.
Install the generator 5 to 10 feet away from your home, and make sure the exhaust faces away from windows and doors to minimize the risk of carbon monoxide poisoning.
Always follow local codes and safety guidelines to protect your household.
