Can You Set Up a Standby Generator in Your Garage Safely?

can you set up a standby generator in your garage

The idea of having a standby generator for your home is incredibly appealing, particularly in areas prone to power outages. These generators ensure that critical appliances and systems remain operational, providing comfort and safety during electrical disruptions.

However, the placement of a standby generator is crucial to its safe operation. One common question homeowners ask is, “Can you set up a standby generator in your garage?”

The short answer is no, but understanding the reasons why and exploring alternative emergency power solutions can help you make informed decisions. Keep reading to find out more home generator setup tips. 

Understanding the Dangers of Indoor Generator Use

First and foremost, it is essential to understand why setting up a standby generator in your garage or any enclosed space is dangerous. Generators emit carbon monoxide (CO), a colorless, odorless gas that can be lethal.

Even small amounts of CO can cause serious health issues, and prolonged exposure can lead to death. The U.S. Consumer Product Safety Commission (CPSC) reports that over 400 people die annually in the United States from CO poisoning, many of which are linked to improper generator use.

Enclosed Space Hazard

You’ve probably heard of people using garages and closed cars as a way of asphyxiation themselves. This is because garages, even those that are well-ventilated, do not provide adequate airflow to disperse CO emissions.

The gas can accumulate quickly, posing a significant risk to anyone inside the garage or nearby areas of the home. That’s why safe generator practices are so important. 

Air Exchange

The limited air exchange in a garage means that CO can seep into the house, especially if the garage is attached. This infiltration can lead to elevated CO levels indoors, endangering the lives of residents.

The problem with CO again is that it’s odorless and colorless, so you won’t be able to tell there’s a problem until it’s too late. Also, if you are sleeping while this poisoning happens, you could pass away before you even have symptoms. 

Fuel Storage

Generators typically run on gasoline, diesel, or propane, all of which are highly flammable. Storing and handling these fuels in a garage introduces a risk of fire or explosion. This is particularly the case if the generator malfunctions or fuel leaks occur.

Heat and Sparks

Generators produce significant heat and can emit sparks. When operated in an enclosed space like a garage, the risk of igniting flammable materials increases. This is particularly concerning in garages where other flammable substances are often stored.

Manufacturer Recommendations and Local Codes

Generator installation guides explicitly warn against operating generators indoors, including garages. Most product manuals will have clear instructions stating that the generator should be placed outdoors, at a safe distance from windows, doors, and vents to ensure that exhaust fumes do not enter the home.

Furthermore, local building codes and regulations often have strict guidelines about the placement and operation of standby generators. This generally prohibits their use in enclosed spaces like garages.

Alternative Solutions for Safe Generator Use

While placing a generator in a garage is not safe, several alternatives can ensure safe operation and convenience during power outages. Here are some for you to consider for your home or office. 

Outdoor Placement

The safest way to operate a standby generator is to place it outdoors. Choose a location that is at least 20 feet away from any doors, windows, or vents to prevent CO from entering your home. Make sure the exhaust is pointing away from the house. 

Ensure the area is dry, well-ventilated, and protected from direct exposure to the elements.

Generator Enclosures

If you are concerned about protecting your generator from harsh weather conditions, consider using a specially designed generator enclosure or a generator shed.

These enclosures are designed to provide adequate ventilation while shielding the generator from rain, snow, and debris. Ensure the enclosure meets the manufacturer’s specifications for safe operation.

Transfer Switch

Installing a transfer switch can make operating your generator more convenient and safe. A transfer switch connects your generator directly to your home’s electrical panel. This allows you to power selected circuits without running extension cords.

This setup not only streamlines the use of your generator but also ensures compliance with safety standards.

Portable vs. Standby Generators

While this article focuses on standby generators, if you are using a portable generator, the same safety principles apply. Portable generators should always be used outdoors, far from any openings in your home.

Additionally, never refuel a generator while it is running or still hot. This can cause fires or explosions.

Installation Best Practices

For those considering a standby generator, professional installation is highly recommended. A licensed electrician or generator installer will ensure that the generator is set up correctly and in compliance with all safety codes. Key installation best practices include:

Proper Site Selection

Choose a site with good drainage to avoid water accumulation around the generator. The site should be level and clear of any obstructions that could impede ventilation.

Secure Mounting

The generator should be mounted on a stable, non-combustible surface, such as a concrete pad. This prevents movement or tipping, which could damage the generator or cause fuel spills. 

Electrical Connections

A professional installer will ensure that all electrical connections are safe and meet local codes. This includes proper grounding of the generator and safe routing of wiring to the transfer switch.

Regular Maintenance

Like any mechanical device, generators require regular maintenance to operate safely and efficiently. Follow the manufacturer’s maintenance schedule, which typically includes checking the oil, inspecting fuel lines, and testing the generator periodically.
