Generator Safety: Detached Garages Need Distance Too
Last updated: September 24, 2026
A recent report from The Cool Down shed light on a common misunderstanding regarding generator placement and safety regulations. Many homeowners are aware of the requirement to keep portable generators a safe distance from their main residence, but this crucial rule often extends to detached structures as well. This homeowner's experience serves as a valuable reminder: the 20-foot rule isn't just for the house itself. Detached garages, workshops, and even sheds can be vulnerable to carbon monoxide buildup and fire hazards if a generator is placed too close. This is particularly important for those who use detached structures for storage, hobbies, or even as auxiliary living spaces. This week, consider taking a proactive step to ensure your generator setup is safe. First, identify all structures on your property that could be affected by generator exhaust or proximity. This includes your primary dwelling, any attached garages, and importantly, all detached buildings. Next, measure the distance from where you plan to operate your generator to each of these structures. A minimum of 20 feet is the widely recommended safety buffer. This distance helps prevent dangerous levels of carbon monoxide from accumulating inside buildings and reduces the risk of fire from exhaust heat. It's also wise to familiarize yourself with your generator's specific operating manual. Manufacturers often provide detailed guidelines on safe placement and ventilation, which can complement general safety regulations. Proper ventilation is key to preventing carbon monoxide poisoning, a silent and deadly threat. Finally, consult with a qualified professional. Licensed and insured electricians or home safety experts can assess your property and provide personalized recommendations for generator placement and installation, ensuring compliance with local codes and best practices. For residents in and around Los Angeles, California, ensuring your home's electrical systems and backup power solutions are up to code is paramount. If you're considering a new generator setup or want to double-check your current one, reaching out to a local, licensed professional for a free estimate is a practical step to take this week.
