What observations and communications can a renter organize without disturbing suspected contamination or treating a sign as a diagnosis?
What to record and report
Write down when and where you noticed signs and what you directly observed. Keep copies of messages you send or receive. Take a photo only if you can do so without touching or disturbing suspected material; do not treat an observation as a diagnosis or proof of who is responsible.
USAGov’s tenant complaint guide recommends reading your lease. Check the property’s contact instructions and send management a neutral report through that route. State what and where you observed; ask management to confirm the next step. This is an ordinary message, not a universal legal notice form or deadline.
