Building a strong record of the hazard
Good documentation is what turns "my landlord won't fix it" into evidence. The goal is to show what was wrong, that the landlord knew, and that it went unrepaired.
Start with photos and video of the problem — sparks, scorch marks, exposed wires, or a panel that keeps tripping — captured safely and, when possible, with dates. Keep every written repair request and the landlord's replies, since texts and emails create a timeline of notice.
A licensed electrician's report or invoice can carry a lot of weight, because it describes the fault in professional terms. So can a report from a city or county code inspector who documents the violation. If the problem caused injury or property loss, save medical records, receipts, and photos of the damage.
Organize everything by date so the sequence is clear. This kind of record protects you whether you are negotiating a repair or pursuing a claim. If you want help understanding what your evidence shows, a free, confidential review can walk you through it.
