What Are the Most Common Causes of House Fires?
Last updated October 26, 2026
The short answer
Cooking Accidents Lead the List
Cooking is the leading cause of house fires. Unattended stovetops, grease splatters, and forgotten food in ovens can ignite quickly. A momentary distraction, like a phone call or a child needing attention, is often enough for a fire to start. Keeping your eyes on the stove and setting timers can reduce that risk.
If a grease fire starts, do not use water. Turn off the heat and cover the pan with a metal lid or use baking soda. For oven fires, keep the door closed and turn off the heat. In humid climates, open a window for ventilation but never leave cooking food unattended.
Heating Equipment Risks
Heating equipment, such as space heaters, furnaces, and fireplaces, is another common fire source. Space heaters cause many fires when placed too close to curtains, bedding, or furniture. A general rule is to keep anything that can burn at least three feet from the heater. Always turn off portable heaters before you sleep or leave the house.
Furnaces and chimneys require regular maintenance. Have a professional inspect your heating system yearly, especially before the cooler months. In a humid subtropical climate, heating use may be brief, but a faulty system can still cause a fire. Check for frayed cords or damaged plugs on any electric heater.
- Keep space heaters at least three feet from anything flammable
- Never leave a heater running while you sleep
- Have your furnace inspected yearly
- Clean chimneys and flues regularly
- Use heaters with automatic shutoff features
- Place heaters on a level, non-flammable surface
Electrical Faults and Wiring
Electrical fires often stem from outdated wiring, overloaded outlets, or faulty appliances. Frayed cords, loose connections, and frequent circuit breaker trips are warning signs. If a light switch feels warm or you hear buzzing from outlets, address it quickly. An electrician can inspect your home's wiring to spot hazards.
Overloading power strips or using extension cords as permanent wiring is risky. Plug major appliances directly into wall outlets. In older homes, the electrical system may not handle modern loads. If you experience frequent storms, consider surge protectors for sensitive electronics, but never daisy-chain them.
Smoking and Candles
Smoking materials cause fires when cigarettes or ashes come into contact with flammable items. Falling asleep while smoking is a leading factor. If you smoke, do so outside and use deep, sturdy ashtrays. Never dispose of cigarette butts in potted plants or trash bins, as they can smolder and ignite.
Candles are also a hazard, especially when left burning in empty rooms. Place candles on stable surfaces away from drafts, and always extinguish them before leaving. Consider using flameless LED candles instead. In a humid climate, damp matches or lighter fluid can behave unpredictably, so store them safely.
What to Do After a Fire
After a fire is extinguished, your home may face water damage from firefighting efforts. Even a small fire can leave soot, smoke, and moisture behind. Water damage may affect drywall, flooring, and ceilings. If your home has suffered water damage, a professional inspection can assess the extent and guide repairs.
Local water damage pros can handle cleanup and restoration. They often address issues like soaked drywall, warped flooring, and lingering moisture that can lead to mold. If you need help, consider services like water damage inspection or drywall repair. In humid climates, drying out your home quickly is important.
- Contact your insurance company to report the fire. Policies vary, and your insurer decides what is covered.
- Document damage with photos for your claim
- Do not re-enter the home until it is safe
- Seek temporary shelter if needed
- Hire professionals for water damage cleanup

How can I prevent kitchen fires?
Stay in the kitchen while cooking, especially when frying or grilling. Keep flammable items like towels and paper away from the stove. Use a timer to remind you that something is cooking. If a fire starts, turn off the heat and cover the pan with a metal lid.
What should I do if an electrical fire starts?
Do not use water on an electrical fire. Turn off the power at the breaker if you can do so safely, then call for help. If the fire is small, use a Class C fire extinguisher. Evacuate the home if the fire grows.
Does water damage from firefighting require professional help?
Yes, water damage can be extensive. Pros can remove wet drywall, dry out structures, and prevent mold growth. In humid climates like St. Petersburg, acting quickly is key. A water damage inspection can identify hidden moisture and guide repairs.
