Safely Re-Entering a Damaged Home

The Post-Disaster Recovery chapter puts re-entry safety first, "before" the claims process, since none of that matters if entering the structure itself causes an injury. This guide is the actual walkthrough: what to check outside first, the gas and electrical checks, the structural red flags that mean turn around, and the order to move through the house once it's safe to go in. For the insurance and claims process that comes after, see Filing Claims After a Disaster.

Wait for official clearance first

Return only once local authorities have said it's safe to do so. After a significant event, especially an earthquake, trained inspectors may have posted an official placard on the building: green means inspected and safe to occupy without restriction, yellow means restricted or limited use only, red means no entry at all, full stop, regardless of how urgent it feels to get inside. If no placard is posted yet, that doesn't mean it's safe, it may just mean an inspector hasn't reached the property yet.

Before you go anywhere near the door: the exterior check

Walk around the outside of the property first. Damage visible from outside is often a sign of a bigger problem inside.

Don't enter if you see floodwaters, significant visible damage and debris, or if a structural inspector or contractor hasn't yet confirmed the building is sound.

Gas: leave immediately if you detect it

  1. If you smell gas or hear a hissing or blowing sound, don't turn on lights, don't use a phone or anything electrical inside, and don't investigate the source.
  2. Open a window if you can do so quickly and safely, then leave the property immediately.
  3. Turn off the gas at the main valve from outside if you can do so safely; the exact shutoff steps are covered in Fire-Starting & Generator Safety.
  4. Call the gas company or fire department only after you're a safe distance away.

Electrical hazards

If any wiring looks damaged, or anything electrical has been wet, turn off power at the main breaker or fuse box rather than risk it. Have a licensed electrician inspect the system before restoring power to a home that's had any water intrusion or visible wiring damage.

Structural red flags: turn around if you see these

SignWhy it matters
Any indication of collapse or foundation movement The structure may not be able to bear its own weight, let alone yours
Cracked chimney mortar A fire and carbon monoxide hazard even if the rest of the home looks fine
Cracks in the roofline, structural beams, or foundation Signs the building's load-bearing capacity has been compromised
"Stair-step" cracks in drywall, especially after an earthquake A classic sign of structural shifting, not just cosmetic damage

Once it's genuinely safe to go in

A home built before 1980 may contain asbestos, and damage can turn it into an airborne hazard

Asbestos was common in insulation, floor tile, and other building materials in homes built before 1980, and fire or earthquake damage can turn previously stable, contained material brittle and easily disturbed. If you suspect a damaged area contains it, don't touch, sweep, or vacuum it, disturbing it is what actually releases fibers into the air; leave that section alone and have it tested or removed by a certified asbestos professional before doing any further cleanup nearby.

Move through the home in this rough order:

  1. Stairs and banisters: test stability before putting your full weight on them.
  2. Windows and doors: look for jamming or cracks radiating out from the corners, a sign of structural movement.
  3. Appliances: check connections; anything that got wet needs to dry out completely before it's powered on.
  4. Attic: check for smoke or fire damage, especially after a wildfire.
  5. Basement: inspect for cracks that could indicate a structural problem, not just water damage.
  6. Stay alert for objects that could fall from cabinets or shelving that shifted during the event.

Water, sewage, and mold

Tip

Race the 24-48 hour window, not just watch for the smell afterward

Mold can start growing within 24 to 48 hours of anything getting wet, so the actual goal is getting materials fully dry inside that window, not waiting to notice a musty smell later. Run fans and a dehumidifier, open doors and windows if outdoor air is drier than inside, and keep going until indoor humidity is at or below 50%. It's only a guideline, not a guarantee either way, but it's the practical target worth aiming for while you're already in cleanup mode.

Document before you clean anything up

Take photos and video of every damaged area before repairs or cleanup begin, and separate debris into yard waste, building materials, and regular trash as you go. This is the exact evidence the claims process depends on; see Filing Claims After a Disaster for what happens next.
