Why exposed wiring is urgent
Exposed or bare wiring is a serious safety hazard, and your landlord is generally required to fix it under California's habitability standard, Civil Code Section 1941.1.
Bare wires can cause electric shock if touched and can spark and start a fire, especially if they get wet or come into contact with metal. Wiring that is hanging loose, missing its cover, or poking out of a wall, ceiling, or outlet should be treated as urgent — not decorative wear.
Do not touch exposed wires, and keep children and water away from them. If a wire is live and you cannot safely avoid it, switching off the breaker for that area can reduce the danger.
Report the problem to your landlord in writing, describe exactly where the exposed wiring is, and include photos if you can take them safely. Because this is a shock and fire risk, a landlord who ignores it may be failing their legal duty. If that happens, a free, confidential review can explain your rights.
