How to Document Mold in Your Rental

Proper documentation is essential for protecting your rights and building a case if issues escalate.

What to Document

The Mold Itself

  • Location (room, wall, ceiling, etc.)
  • Size (measure or compare to common objects)
  • Color and appearance
  • Any musty or moldy odors
  • Moisture sources nearby
  • Any visible water damage

Related Conditions

  • Leaks or water intrusion
  • Humidity levels (if you have a meter)
  • Ventilation issues
  • Previous water damage
  • Condensation on windows/walls
  • Any related health symptoms

Photo Documentation Best Practices

  1. 1

    Use Good Lighting

    Mold can be hard to see in photos. Use natural light or a flashlight to ensure the mold is clearly visible.

  2. 2

    Take Multiple Angles

    Wide shots showing context, medium shots showing the affected area, and close-ups showing detail.

  3. 3

    Include a Reference Object

    Place a ruler, coin, or your hand in frame to show scale.

Written Communication Records

Always Communicate in Writing

Email is ideal because it:

  • Creates automatic timestamps
  • Shows delivery/read receipts
  • Is easy to organize and search
  • Can be easily shared with attorneys

What to Include in Reports

  • Date you discovered the problem
  • Specific location of the mold
  • Description of what you observed
  • Any health symptoms
  • Request for inspection and remediation
  • Request for response timeline

Creating a Documentation Timeline

Keep a Mold Issue Log

Create a simple log or spreadsheet tracking:

Dates

When you discovered mold, reported it, and any follow-ups.

Communications

Every email, call, or in-person conversation with your landlord.

Responses

What your landlord said or did (or didn't do) in response.

Health Symptom Documentation

Track Your Symptoms

  • Keep a symptom diary with dates
  • Note when symptoms worsen (at home vs. away)
  • Document doctor visits related to symptoms
  • Get medical records if seeking treatment
  • Note if symptoms improve when away from home

Important Disclaimer

We cannot provide medical advice. If you're experiencing health symptoms, consult a healthcare provider.

Documentation of symptoms and medical visits can be relevant in legal proceedings, but establishing health causation is complex and typically requires medical expert testimony.

Professional Documentation

Consider professional documentation when escalating:

Mold Inspector

A professional inspection report carries more weight than tenant photos alone.

Medical Records

If claiming health impacts, documentation from healthcare providers is important.

Certified Mail
