Vape aerosol is not just harmless water vapor. In multi-unit housing it can enter nearby units and common areas, and a lease may regulate vaping separately from cigarette smoking.

Your goal is not to create dramatic evidence. Your goal is to create believable evidence showing what happened, where it happened, when it happened, how often it happened, and when the landlord was told.

Document safely first

Do not enter another tenant’s unit, block required ventilation, or create a confrontation to prove the source.

Capture the condition clearly

  1. Start wide. Take one photo that identifies the room, wall, fixture, doorway, appliance, common area or other location.
  2. Move closer. Take medium and close images showing the specific defect. Use a ruler, thermometer, clock, work-order screen or other ordinary reference only when it helps explain the condition.
  3. Use video for movement, sound or recurrence. Leaks, flickering, pests, failed locks, alarms and repeated system failures are often easier to understand on a short video than in a still photo.
  4. Keep a time log that distinguishes suspected vaping aerosol from cigarette or marijuana smoke when you can reasonably tell the difference.
  5. Photograph posted no-vaping signs, vaping activity in prohibited common areas, and the location of nearby windows or air intakes.
  6. Video recurring visible clouds only when it can be done from your own unit or a lawful common area without escalating a confrontation.
  7. Save written complaints and note whether management treats vaping differently from the written policy.
  8. Send written notice. State the problem, exact location, when it began, whether it is getting worse, and what repair or action you are requesting. Save proof of delivery.
  9. Build one timeline. Put photos, work orders, management replies, inspection dates, receipts and third-party reports in date order. That timeline can become the backbone of a code complaint, legal-aid intake or RentalFacts listing.

Make your evidence harder to attack

Keep the affected area reasonably clean when cleanliness is relevant to the dispute. Do not stage damage, exaggerate symptoms, edit images in a misleading way, or provoke a neighbor or employee just to get a reaction on camera. Preserve original files whenever possible.

RentalFacts tip: A strong public report should separate what you personally observed from what an inspector, technician, doctor, neighbor or government agency reported.
