The ceiling is leaking. The heater died in January. The roaches have started paying rent themselves. At some point, a strongly worded text to your landlord stops being a strategy and starts being a habit. That's when it's time to make it official.
Los Angeles gives renters two straightforward ways to file a habitability complaint: call 311 or use the LAHD online portal (the Los Angeles Housing Department). Both routes are free, both create a paper trail, and both can trigger an official inspection of your unit. That paper trail matters more than you might think.
Know which agency handles your problem
Not every complaint goes to the same desk. LAHD handles most residential habitability issues — broken heat, persistent leaks, mold, pest infestations, and conditions that make a unit substandard. If your building has enough unresolved violations, it can land in REAP (the Rent Escrow Account Program), which allows tenants to pay reduced rent into an escrow account instead of handing it to a landlord who hasn't fixed anything.
LADBS — the Department of Building and Safety — covers structural and code issues: illegal additions, unpermitted work, unsafe electrical or plumbing. If your stairwell is caving in, that's their lane.
LAPD is the right call if a habitability issue crosses into harassment or illegal lockout territory. And if you're in a rent-stabilized unit, the Rent Registry is worth knowing — it's where RSO properties are tracked, and discrepancies there can matter if you ever dispute your legal rent.
What actually happens after you file
Once a complaint is logged, an inspector is typically assigned to visit the property. If violations are confirmed, the landlord receives a notice with a timeline to correct them. Ignore enough notices and the building risks REAP status — a significant financial consequence for owners, and a meaningful lever for tenants.
Document everything before you file: photos with timestamps, written requests you've sent, any responses (or non-responses) from your landlord. The more specific your complaint, the harder it is to dismiss.
Filing a complaint is also legally protected activity in Los Angeles. Retaliation — a rent hike, a sudden eviction notice — shortly after a complaint is a red flag the city takes seriously. Keep the timeline written down.
Your apartment should be livable. That's not a favor your landlord is doing you — it's the legal minimum. When they fall short, 311 is a perfectly reasonable next move.
