Your first steps with a fire hazard
Start by protecting your safety, then build a clear record so the problem gets taken seriously.
First, address any immediate danger. If you smell smoke or gas, see flames, or believe a fire could start, leave and call 911. Do not disable smoke or carbon monoxide alarms, and do not use equipment that seems unsafe.
Second, report the hazard to your landlord in writing — text, email, or a letter — and keep a copy. Describe the problem, where it is, and when you noticed it, and say clearly that you consider it a fire-safety issue.
Third, take photos or video if you can do so safely, and save every message about the problem. Note the dates of your requests and any responses.
Fourth, if the landlord does not act, you can report the hazard to your local fire department or code-enforcement office, which can inspect and order repairs.
If a landlord ignores a real fire hazard, you have options. A free, confidential review can walk you through your rights and what usually comes next.
