Interior doors are named more often than exterior ones — bedroom doors, closet doors, the door to a basement or a nursery. The report is rarely "a door was open that I left closed." It's more specific: the door was watched, or heard, moving. A latch clicks. A door swings a few inches and stops. A door gets pushed shut, firmly, with no wind and no one in the hallway.
A few patterns repeat across filings. It's usually the same door, not a rotating cast — whatever else happens in the house, this one door keeps doing it. It clusters around a particular time of day, often dusk or the hour before sleep, though nothing about that timing is universal. Pets are frequently mentioned as reacting a beat before a person notices anything — ears up, a stare at the door, a refusal to walk past it that outlasts the incident itself.
Before anything else, work through this in order. Each of these accounts for a large share of these reports once someone actually checked.
Air pressure is the most common cause by far. A running furnace or air handler, a bathroom or kitchen exhaust fan, a fireplace draw, or simply closing a door elsewhere in the house can change the air pressure enough to push a loosely latched door open or pull it shut — the same "stack effect" that makes old houses moan in winter. Test it: note whether the movement lines up with the HVAC cycling on or off, and try cracking a window on the opposite side of the house to equalize pressure and see if it stops.
Next, check whether the door is actually plumb. Hold a level against the leading edge, or set a coin on the floor near the latch side and see which way it rolls. A door that swings open on its own when released is very often just out of true — commonly because the top hinge screws have loosened and let the door sag toward the latch side under its own weight.
Check the strike plate. If it's a hair out of alignment, the door can look and sound closed without the latch actually catching, which means the smallest vibration — footsteps upstairs, a truck passing outside, another door closing — is enough to walk it open over the next several minutes.
Seasonal settling matters too. Wood-framed houses expand and contract with humidity; a door that stuck all summer and suddenly swings free in a dry winter is usually the frame relaxing, not the door changing. And if the house has an older pneumatic door closer, check whether it's simply worn out and drifting on its own schedule.
Rule out these five — pressure, plumb, latch, frame, closer — before you rule out anything else.
Work through that list honestly, because most filings resolve there. But not all of them do. A minority of accounts remain where the mundane checklist has been run — pressure tested, hinges checked, latch adjusted, a log kept for weeks — and the door still moves on a pattern that doesn't correlate with any of it.
The law has touched this territory exactly once, and it's worth knowing precisely what it did and didn't decide. In Stambovsky v. Ackley, 572 N.Y.S.2d 672 (N.Y. App. Div. 1991), a New York appellate court considered a Nyack house whose owner had spent years telling local newspapers, a national magazine, and a walking tour that it was haunted — including reports of objects moving without explanation. When she sold the house without mentioning any of that to the buyer, the court let the buyer out of the contract, holding that because the seller had built the house's public reputation herself, it "is haunted" as a matter of law for purposes of that claim. The court never ruled on what actually happened in that house. It ruled on what the seller had told the world and then failed to tell one buyer. (This is general information, not legal advice.)
That distinction is the honest version of the uncanny reading too. This registry doesn't resolve mechanism, and it isn't trying to. What it holds is pattern and testimony — reports that a specific door in a specific house keeps doing a specific thing, filed by people who checked the ordinary explanations first and are recording what was left over.
If it's happening in your house right now, spend a week on the boring version before you spend any time on the other one.
Check plumb and hinge screws the first night. Check the strike plate alignment. Hold a lit incense stick or a tissue near the door frame, and near other doors and windows in the house, to see where air is actually moving — you're looking for a draft path that explains it, not just ruling out an open window in the same room.
Then keep a log for at least two weeks: date, time, which door, weather, whether the HVAC was running, who else was home, and whether a pet reacted first. Note it even on nights nothing happens — a log with gaps is more useful than a log with only the interesting entries, because it shows whether the pattern is as consistent as it feels in the moment.
Most of the time, the log itself is what resolves it — it'll show the movement tracking the furnace schedule, or a weather front, or a housemate's habit of letting a screen door bang two rooms away. When it doesn't resolve that way, the log becomes the record worth keeping.
Before you decide this is unusual, search your own address in the registry. Other residents — current or past — may have filed on the same door, and a pattern that looks strange in isolation sometimes reads differently next to someone else's account of the same house.
If nothing comes up, that isn't a verdict. It usually just means no one wrote it down. Most houses have no formal channel for this kind of report — no box on a disclosure form for "the hall closet door lets itself out." California law requires sellers to disclose a death on the property within the past three years (Civil Code §1710.2), but a door with a habit isn't covered by any statute, in California or anywhere else. This registry is the informal record that fills that gap.
So if you've run the checklist, kept the log, and the door is still doing something the log can't explain — file it. Note the door, the room, the pattern, and the things you already ruled out. The next person to live behind that door will be glad someone did.
Yes. Running HVAC systems, exhaust fans, fireplaces, and even closing a door elsewhere in the house change air pressure enough to move a loosely latched door — the same effect that makes old houses creak and moan in winter. It's the single most common explanation filed against this phenomenon.
Not on its own, and courts generally don't rule on whether paranormal activity is real. The one notable exception, Stambovsky v. Ackley (1991), turned on a New York seller's own public statements about her house, not on independent proof of anything supernatural. This is general information, not legal advice.
Most states have no disclosure requirement for reported paranormal activity at all. California requires disclosure of a death on the property within three years under Civil Code §1710.2, but that's a narrow, specific statute — it doesn't reach something like a door with a habit, which is why informal records like this one exist.
Check the record for your address — or add what happened, for whoever lives there next.
