Short answer: Not until the fire department says it is safe. Even after a small fire, damaged wiring, gas lines, weakened structures, soot and smoke residue can make a home unsafe to live in for a while.

The urge to go home after a fire is strong. Here is what makes a home unsafe and how to know when it is ready.

What makes a home unsafe after a fire

Never go back inside until the fire department tells you it is safe. If you smell gas at any time, leave and call 911 or your gas company.

  • Damaged electrical wiring that could spark or start another fire
  • Gas lines or appliances that may be leaking
  • Weakened floors, ceilings or roofs
  • Soot and smoke residue, which can irritate the lungs
  • Water from firefighting, which can lead to mold

Soot often gathers around outlets, vents and ceilings, far from the flames.

Before anyone moves back in

  • The fire department has cleared the home
  • The power and gas have been checked, and turned back on by the utility or a professional
  • Smoke alarms are working
  • Soot has been cleaned from living areas
  • Wet materials have been dried

Smoke and soot travel well beyond the room where a fire starts.

What to throw away

Heat, smoke and firefighting water can make everyday items unsafe.

  • Food exposed to heat, smoke or soot, even in closed containers
  • Medicines exposed to heat, smoke or water, so ask a pharmacist about replacing them
  • Baby bottles, pacifiers and cosmetics exposed to smoke
  • Anything burned, melted or soaked with dirty water

Where to get help

The American Red Cross helps families after home fires with emergency needs such as a place to stay. Your homeowners insurance may also pay for somewhere to stay while the home is repaired.

Mistakes to avoid

  • Going back in before the fire department clears the home
  • Switching on power or gas yourself
  • Wiping soot with a wet cloth
  • Eating food that was near the fire
  • Throwing things away before your insurer has seen them

When to call a professional

Call a fire damage restoration provider to board up openings, remove firefighting water, clean soot and remove smoke odor. They can also document the damage for your insurance claim.

Frequently asked questions

How long after a fire can I go home?

It depends on the damage. After a small fire it may be days. After a larger fire it can be weeks or months.


Is smoke smell dangerous?

Smoke residue contains fine particles that can irritate the lungs. Have the home cleaned before living there, especially with children or anyone with asthma.


Can I clean up myself?

Light cleaning may be possible once the home is safe, but heavy soot, smoke odor and water need professional cleanup.


Will insurance pay for a hotel?

Many policies include additional living expenses while the home cannot be lived in. Keep every receipt.
