Cooking is the leading cause of home fires and home fire injuries in the United States, according to NFPA.
Kitchen fires remain common despite modern fire safety technology, so understanding when and why they start is the first step to preventing them.
The statistics below, from the U.S. Fire Administration and NFPA, cover how often kitchen fires happen, what causes them, and what they cost.
Key Kitchen Fire Statistics
U.S. residential buildings average 187,500 cooking fires a year, which cause about 165 deaths, 3,325 injuries and nearly $1.5 billion in property loss, according to the U.S. Fire Administration.
Cooking not only topped the list as the leading cause of residential building fires but also as the primary source of related injuries. Alongside this, these fires frequently occurred between 4 to 9 p.m., peaking during dinner time, with November registering the highest incidence of such fires.
According to USFA, a staggering 93% of these cooking fires remained confined, typically involving oil, fat, and grease, which were the leading materials ignited in nonconfined fires. While the fires were mostly contained to the object or room of origin, the leading cause of ignition was unattended equipment.
However, despite the presence of smoke alarms in 67% of nonconfined cooking fires, only 9% had Automatic Extinguishing Systems (AESs), underscoring the need for more comprehensive fire safety measures in homes.
What Causes Kitchen Fires?
Most kitchen fires start when cooking oil, fat or grease ignites on equipment left unattended, which USFA identifies as the leading cause of ignition.

Alongside this, multifamily residential buildings experienced the highest number of kitchen fires, with 27% of kitchen fires in these buildings being nonconfined.

When it comes to timing, most fires happen at dinnertime, between 4 and 9 p.m.

Another significant factor contributing to the prevalence of kitchen fires is the time of year.
Kitchen fires peak in November, with high numbers through the holiday season. This spike is likely due to the increased number of social gatherings during the holiday season, including Thanksgiving, Christmas, and New Year’s celebrations.

Kitchen Fire Deaths
Cooking fire deaths have declined since the 1980s but more slowly than overall home fire deaths, so cooking now accounts for a larger share of home fire fatalities.

How Common Are Commercial Kitchen Fires?
U.S. fire departments respond to an average of 7,410 structure fires a year in restaurants and bars, and cooking equipment causes 61% of them, according to NFPA data for 2010–2014. Commercial kitchens are protected by hood suppression systems over the cooking line; see our restaurant fire suppression systems in Houston.
How Do You Prevent Kitchen Fires?
Never leave cooking unattended and keep a lid within reach at home; in commercial kitchens, keep a Class K extinguisher at the cooking line and have the hood suppression system inspected every six months as NFPA 96 requires.
Safety measures are also crucial, especially during peak times and holidays. The data underlines the need for better fire safety education, which may be particularly true for oil-based fires.
Overall, it’s vital for residents to install and maintain their fire safety measures. These devices can help reduce kitchen fires and their devastating impact.
