What to do if…
your porch, balcony, or deck feels like it is pulling away from the building

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Get everyone off it immediately, keep people away from the area underneath, and block access so nobody steps onto it by mistake. If it is actively moving, cracking, dropping material, injuring someone, trapping someone, or threatening a public area, call 911.

Do not do these things

  • Do not bounce on it, lean on it, add weight, or ask someone to stand on it to see if it holds.
  • Do not try a quick DIY fix with extra screws, brackets, straps, or temporary posts while it may still be moving.
  • Do not stand underneath it, park under it, or walk through the likely fall zone.
  • Do not ignore new cracking, loud pops or creaks, widening gaps, sagging, tilted posts, or visible movement.
  • If you smell gas, do not use flames, smoke, or operate electrical switches near the smell.

What to do now

  1. Get to a safer pause: move everyone off the porch, balcony, or deck and away from the edge. Keep children, visitors, and pets well back.
  2. Block access from inside: close and lock the door leading to it if you can, put up a clear note saying “DO NOT USE,” and tell everyone in the home or unit that it is unsafe.
  3. Clear the fall zone: keep people away from the space underneath and around it. Move cars only if you can do so without going under or near the structure.
  4. Call 911 if there is immediate danger: call if it is actively shifting, cracking loudly, dropping pieces, leaning over a walkway or public area, or if anyone is hurt, trapped, or unable to move away safely.
  5. Report the unsafe structure locally: if it is not a 911 emergency but still unsafe, contact your city or county building department, code enforcement office, or 311 where available. Say plainly: “A porch, balcony, or deck appears to be pulling away from the building and is unsafe to use.”
  6. If you rent or live in a shared building: notify the landlord, property manager, condo association, or HOA immediately. Put it in writing: “The porch/balcony/deck appears to be pulling away from the building. It is not safe to use and needs urgent inspection.”
  7. Document only from a safe place: take photos or video from indoors, across the yard, or another safe distance. Note when it started, what you heard or felt, and recent triggers such as storms, heavy rain, snow, rot, repair work, or nearby digging.
  8. Ask for urgent professional assessment: request inspection by a licensed structural engineer or other qualified building professional. Ask them to check the attachment to the building, ledger or connection points, posts, beams, fasteners, railing, flashing, rot, corrosion, and movement.
  9. If utilities may be involved: if you smell gas, hear hissing, see damaged electrical equipment, or suspect utility lines were affected, move away and call 911 or the utility from outside the area.

What can wait

  • You do not need to decide the repair method, contractor, materials, permits, or cost right now.
  • You do not need to prove who is responsible before making the area unsafe to use.
  • Insurance usually does not need to be the first call unless your insurer has an emergency reporting line and the immediate hazard is already controlled.
  • You do not need to inspect underneath it yourself.

Important reassurance

Taking this seriously is not overreacting. A porch, balcony, or deck that is separating from the building can fail suddenly, and the safest first move is to keep weight off it and keep people out of the fall zone.

Scope note

These are first steps only: keep people away, report the hazard, document safely, and get qualified inspection. Later decisions about repairs, responsibility, permits, rent, insurance, or enforcement may need specialist help.

Important note

This is general information, not engineering, legal, insurance, medical, or other professional advice. If collapse, falling debris, fire, injury, entrapment, or a gas or electrical hazard may be happening now, move away and call emergency services.
