Home generator ownership is surging across the United States, driven by an increasing frequency of major weather-related outages and growing awareness of grid vulnerability. Both portable generators and automatic standby generators are experiencing strong demand, with the residential generator market expected to exceed $5 billion annually by 2027. This page compiles the key statistics on home generator ownership rates, market size, sales trends, hurricane-driven demand spikes, leading brands, and safety data — drawing on IBHS research, industry reports, and government tracking.
Key Stat: Approximately 1 in 5 U.S. households with a detached home owns a portable generator — with ownership rates in hurricane-prone and rural areas approaching 1 in 3.

Frequently Asked Questions
How many U.S. homes have a generator?
Approximately 20% of U.S. detached homeowners own at least one generator, according to IBHS survey data. Ownership rates are significantly higher in hurricane-prone coastal states (around 33%) and in rural areas with frequent outages (around 28%). About 6% of U.S. homeowners have a permanent automatic standby generator installed.
How much does a home standby generator cost?
Automatic standby generators for whole-home coverage typically cost $5,000–$12,000 fully installed, depending on size (11–22 kW), fuel type, and regional labor rates. A Generac 22 kW generator with installation has a median cost of approximately $7,500 in the U.S. Natural gas models are more common in urban/suburban areas; propane standby generators are standard in rural areas without utility gas service.
What is the biggest home generator brand?
Generac dominates the U.S. residential standby generator market with approximately 75% market share, with Kohler a distant second at around 12%. In the portable generator segment, Honda leads on reliability and longevity, while Champion and Westinghouse are the value leaders. Briggs & Stratton, DeWalt, and Ryobi also hold meaningful portable market share.
Why do generator sales spike before hurricanes?
Demand for portable generators spikes roughly 10x above normal at major retailers in the 72 hours before a hurricane landfall, according to IBHS research. This panic-buying pattern means generators typically sell out 72–96 hours before a storm hits. Emergency management agencies consistently advise purchasing generators before hurricane season (June 1) rather than waiting for a storm warning.
Are portable generators dangerous?
Portable generators are the #1 cause of carbon monoxide poisoning deaths in the U.S., killing over 900 people and sending 6,000+ to emergency rooms annually, according to CPSC and CDC data. The primary rule: never run a generator indoors, in a garage, or within 15 feet of any home opening. All generators manufactured after May 2024 are required by CPSC to include automatic CO shutoff sensors — a significant safety improvement.
