Safe Home Generator Placement: How to Choose the Right Location Around Your House
When it comes to installing a home standby generator, location is one of the most important decisions you will make. The right placement keeps your family safe, protects your home, and ensures the generator can run reliably whenever the power goes out.
Safe distance from the house and combustibles
Home standby generators should never be placed directly against the house or underneath low decks and porches. As a general rule, generators need at least 3 feet of clearance from combustible materials such as wood and vinyl siding. If a unit must go under a deck, that deck should be at least 5 feet above the top of the generator. While generator fires are rare, these clearances help prevent a small problem from becoming a serious hazard for your home.
Protecting your home from carbon monoxide
Because automatic standby generators use internal combustion engines, they produce carbon monoxide, a colorless, odorless gas that can be deadly if it enters the living space. To reduce this risk, generators should be installed at least 5 feet away from any opening into the home. Openings include doors and windows, but also dryer vents, foundation vents, attic vents, and other penetrations in the building shell. We strongly recommend installing carbon monoxide detectors in rooms near where a generator is located, especially if the unit is within about 10 feet of the home.
Clearances from tanks, meters, and panels
In addition to the house itself, generators need safe separation from other equipment on the property. Home standby units should be installed at least 10 feet away from propane tanks, and should not be placed directly in front of the electrical meter or any electrical panels. A minimum of 3 feet of unobstructed space should be maintained on all sides of the generator. This open area allows for proper airflow so the unit can cool itself, and it gives technicians enough room to work safely during inspections, repairs, and routine maintenance.
Going beyond the basics
These guidelines cover the most common clearance and safety requirements for home standby generator installations. In many cases, your local codes and the manufacturer’s installation manual will have additional rules that must be followed. For more detailed information, installers reference standards such as NFPA 37, which outlines official requirements for stationary combustion engines and gas turbines, including home standby generators.
