Proving a pattern of harassment
Proving harassment is usually about showing a pattern of improper conduct and connecting it to the landlord — and because harassment often leaves little physical trace, your records are the evidence.
The foundation is a detailed incident log: for each event, the date, time, what happened, exactly what was said or done, where, and any witnesses. A consistent timeline reveals the pattern that a single incident cannot. Pair it with saved communications — texts, emails, voicemails, and notices — that capture the landlord's own words.
Physical evidence helps where it exists: photos of a changed lock, a shut-off utility, or ignored repairs. Reports to police or code enforcement, with dates and report numbers, add official weight. Statements from neighbors who witnessed the conduct can corroborate your account. If the harassment followed a complaint you made, records showing that timing can support a retaliation claim.
Organize everything by date so the pattern and any connection to your complaints is clear. This kind of record is what makes harassment provable. If you want help understanding what your evidence shows, a free, confidential review can walk you through it.
