Garage and Detached Structure Fire Prevention

Garages, sheds, and detached workshops often store gasoline, propane, paints, and power tools that increase fire intensity. Because many garages attach to the home, a fire that starts in the garage can spread to living spaces within minutes.

Flammable Storage

Store gasoline and solvents in approved containers, away from water heaters and furnaces. Never run vehicles inside with the door closed while engines are hot. Keep oily rags in metal containers with tight lids—not piled on workbenches.

Electrical and Heat Sources

Replace damaged extension cords, avoid overloading outlets, and have older garage wiring inspected by a licensed electrician. Maintain clearance around water heaters and install a heat alarm if local code recommends it for garage spaces.

Doors and Fire Separation

Attached garages should have a fire-rated door with a self-closing hinge leading to the house. Seal pet doors and gaps that let fumes or fire spread. Detached structures benefit from spacing and noncombustible siding where wildfire risk is elevated.

Detection and Response

Install smoke or heat detection in garages and workshops. Keep a fire extinguisher rated for Class B and C fires near the exit—not buried behind storage. Practice how you would exit if a fire starts while you are working with power tools.

Simple habits—proper storage, clear exits, and working detectors—reduce the likelihood of a garage fire becoming a whole-property claim.
