Can I put a generator in my garage?

Can I put a generator in my garage? This is a common question that arises when individuals are considering generator placement. Generators are extremely useful during power outages and emergencies, providing backup power to keep essential appliances and systems running. However, it is crucial to prioritize safety when using a generator, including where it should be placed.

In this blog post, we will explore the safety guidelines for generator placement and provide valuable information on why running a generator in a garage or enclosed area is not recommended. We will also discuss the proper placement of generators outdoors and highlight other important considerations for generator placement.

Safety Considerations for Generator Placement

Why running a generator indoors is dangerous

Running a generator indoors poses significant risks to your safety. Generators produce exhaust fumes that contain carbon monoxide, which is a colorless and odorless gas. Carbon monoxide is extremely dangerous and can be deadly if inhaled in high concentrations. When a generator is operated indoors, such as in a garage or in an enclosed area, the exhaust fumes can quickly build up and lead to carbon monoxide poisoning.

Potential risks of running a generator in a garage or enclosed area

Running a generator in a garage or an enclosed area increases the risk of carbon monoxide poisoning even further. Garages typically have poor ventilation, which means that there is limited airflow to dissipate the exhaust fumes. This can result in a buildup of carbon monoxide inside the garage, putting anyone who is in the vicinity at risk.

In addition to carbon monoxide, generators also produce heat, and running them in an enclosed space can lead to overheating. This can cause the generator to malfunction or even start a fire, posing a significant safety hazard.

Proper Generator Placement

Outdoor placement as the recommended option

To ensure the safety of you and your family, it is highly recommended to place your generator outdoors. Outdoor placement provides several benefits and reduces the risks associated with running a generator indoors.

One of the main advantages of outdoor placement is the availability of ample ventilation. When a generator is located outside, there is plenty of fresh air to disperse the exhaust fumes, minimizing the risk of carbon monoxide buildup.

Positioning the generator away from doors and windows

When positioning your generator outdoors, it is important to place it away from doors and windows. This is to prevent the exhaust fumes from entering the house through open entrances. Even with closed doors and windows, there is still a possibility of fumes seeping in, which can be hazardous to your health.

Ensure that the generator is positioned at least 20 feet away from any doors, windows, or vents. This distance will help reduce the risk of carbon monoxide entering the living spaces.

Providing a stable and level surface for the generator

Another important consideration when placing a generator outdoors is to provide a stable and level surface for it. This ensures the safety and proper functioning of the generator. Placing the generator on an unstable or uneven surface can lead to accidents, such as tipping over, which can cause damage to the generator and pose a safety risk.

It is recommended to place the generator on a flat surface, such as a concrete pad or a stable platform. This will help maintain the stability of the generator and prevent any potential accidents.

Other Generator Placement Considerations

Protection from weather elements

While generators are designed to withstand various weather conditions, it is still important to protect them from prolonged exposure to rain, snow, or extreme temperatures. Moisture can damage the electrical components of the generator, rendering it unsafe or inoperable.

Consider using a generator cover to protect it from rain and snow when it is not in use. This will help prolong its lifespan and ensure its functionality when you need it most.

Noise considerations

Generators can be noisy when running, which can be disruptive to you and your neighbors. When placing your generator outdoors, consider its proximity to living areas or neighboring properties. Position it at an appropriate distance to minimize the noise level indoors and reduce potential disturbances to others.

If noise reduction is a significant concern, you can explore noise-reducing measures such as using insulation or sound barriers to help minimize the noise produced by the generator.

Compliance with local regulations

It is essential to check and comply with the local ordinances and regulations regarding generator placement. Different areas may have specific guidelines or restrictions on where and how generators should be placed. By adhering to these regulations, you can ensure the safety of yourself and others while using a generator.

Additionally, it is important to follow any specific guidelines provided by the generator manufacturer in terms of proper placement and operation. These guidelines are designed to maximize safety and prevent potential hazards.


Proper generator placement is crucial for ensuring the safety of your household. It is never safe to run a generator indoors, in a garage, or in an enclosed area due to the risk of carbon monoxide poisoning and other potential hazards. Outdoor placement is highly recommended, along with positioning the generator away from doors and windows.

By following the safety guidelines and considering important factors such as stable placement, protection from the elements, noise control, and compliance with local regulations, you can use your generator safely and effectively during power outages and emergencies.

Remember, prioritizing safety should always be the top priority when using a generator, and proper placement is a critical step in ensuring the well-being of yourself and your loved ones.
