Your mold complaint letter
Tips: what to include in a mold complaint letter
Be specific, dated, and factual. The landlord's lawyer will read your letter. Stick to what you can prove: where the mold is, when you noticed it, what you already asked for, and what you want done.
Keep a parallel photo log. Photograph each location with the room and date written down. One photo with a newspaper or a phone showing the date next to the mold helps establish when it was documented.
Send it in writing, not just text. Physical certified mail or written email with a delivery receipt. A verbal complaint is close to useless for an escalation path.
Keep a copy of everything. The letter, the photos, the delivery receipt, every response (or lack of one). Save them in a folder with dates.
FAQ
Is this letter legally binding?
By itself, no. It is a written record that you notified the landlord of a problem. The legal weight depends on your lease, your state, and how the landlord responds. Talk to a tenant-rights attorney in your state for advice specific to your situation.
Should I mention my rent or threaten to withhold?
Our template stays factual and avoids any threat language. Rent withholding is legal in some states and illegal in others. Do not threaten withholding in writing without a lawyer first, because an incorrect threat can become the landlord's evidence against you.
How do I send it so it counts?
Certified mail with a return receipt is the gold standard. Email with a read receipt is a reasonable second. Text is weakest, screenshots of texts get disputed. Whichever channel, keep the delivery proof in the same folder as the letter.
What if the landlord ignores me?
Most states have a next-step escalation path: a formal written notice with a specific cure period, then a health department report, then possibly withholding rent or breaking the lease. That path is state-specific. A tenant-rights attorney or your local tenant union is the right next call if this letter is ignored.
Are my photos safe here?
Yes. Photos stay in your browser (IndexedDB). Nothing is sent to our servers unless you opt in to email us a copy. If you clear browsing data or switch devices, the photos are gone, so download the PDF before closing the page.
