It is necessary to document loss of heat to prevent unnecessary costs, discomfort, and illness. Minimum-temperature rules vary by location, but tenants can strengthen a complaint with indoor temperature logs and prompt written notice.

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

Never use charcoal, grills or a gas oven to heat a home. If dangerously cold conditions threaten health, use emergency shelter/warming resources or call 211.

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. Place a reliable thermometer away from direct sunlight, cooking appliances and exterior drafts and photograph readings at consistent times.
  5. Record outdoor conditions along with indoor temperatures when the problem is weather-related.
  6. Video a thermostat calling for heat while vents or radiators remain cold when that can be shown safely.
  7. Save every emergency call, text, work order and promised restoration time.
  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.
