What to do if…
someone is loitering in a stairwell or corridor and watching you approach

Short answer

Don’t enter an enclosed stairwell/corridor with them. Create distance, move to a safer/public spot, and call building security/management or 911 if you feel threatened.

Do not do these things

  • Don’t walk past them to “get it over with.”
  • Don’t go straight to your apartment/room door if they might follow and learn where you live.
  • Don’t confront them or try to physically move them along.
  • Don’t let yourself be boxed into a dead end (stairwell, basement level, long hallway, laundry room, parking garage).
  • Don’t get distracted searching for keys or texting while you’re still exposed.
  • Don’t stay to “collect evidence” if you feel unsafe—distance first.

What to do now

  1. Stop your approach and change direction. Turn around calmly and go back to a safer point: outside, a staffed lobby/front desk, a well-lit public area, or anywhere with other people and more than one exit.
  2. Put a barrier between you and them if possible. Step through a locked door, into an access-controlled vestibule, or back outside. If you’re in a secure building, don’t hold doors open behind you.
  3. Get another person involved immediately. Call a friend/housemate on speaker, or contact onsite security/front desk/property management if available. If there are nearby residents, knock only where you can hear activity and you feel safe doing so.
  4. If you feel in danger or think it could turn violent soon: call 911. Tell the dispatcher your exact location (address, floor, nearest entrance), what the person is doing, and that you’re keeping distance in a safer spot.
    • If speaking could put you at risk: you can try texting 911 if it’s available where you are; if you’re not sure it’s available, place a voice call and leave the line open if you can’t talk. (When you can safely speak, a voice call is usually fastest.)
  5. Don’t let yourself be trapped. If they move to block your path, back away toward an exit and a more public area. Choose routes with visibility and multiple ways out (lobby, main entrance), not stairwells or long corridors.
  6. Ask staff to respond using building controls if they can. Security/management may be able to check cameras, send someone to the area, restrict access to floors, or address a malfunctioning entry point—without you approaching the person.
  7. Capture key details quickly (without staring). Approximate age/height, clothing, distinguishing features, exact location, direction of travel, and any vehicle details. This helps if you report it.
  8. Once you’re safe, request a record. If you called 911 or security/management, ask for the incident/call number or the best way to follow up, and ask management to preserve camera footage for the relevant time window.

What can wait

  • You do not need to decide right now whether it’s “suspicious enough.”
  • You do not need to confront them, identify them, or prove intent.
  • You do not need to make long-term decisions about moving, leases, or security upgrades in the moment.

Important reassurance

Your body may freeze, second-guess, or minimize what you’re seeing—that’s a common stress response. Taking simple protective steps (distance, exits, other people, calling for help) is reasonable and can prevent the situation from getting worse.

Scope note

These are first steps for the next minutes to hours. If this happens repeatedly or feels targeted, you may need follow-up with building management and law enforcement.

Important note

This is general safety information, not legal advice. If you believe you’re in immediate danger, prioritize getting to a safer place and calling 911.
