A broken heating system is not a minor inconvenience — it is a habitability violation. California law requires that rental units have functional heating capable of maintaining a minimum temperature of 70°F in all habitable rooms. Landlords who fail to repair heating systems promptly are in breach of the warranty of habitability.
What to Do Immediately
If your heat goes out: notify the landlord in writing the same day (text message with a read receipt, email, or hand-delivered note). Set a repair deadline of 48-72 hours for an emergency condition like no heat. If the landlord doesn’t respond, call code enforcement and request an emergency inspection. Document the temperature inside your unit with a thermometer and photograph the readings with dates.
Emergency conditions justify faster escalation. A habitability problem that threatens health — no heat in cold weather, sewage backup, gas leak, structural collapse — does not get the same 30-day repair deadline as a dripping faucet. Tenants who face genuine emergency conditions can escalate to repair-and-deduct or rent withholding faster than for non-emergency defects. Document the emergency nature of the condition from day one.
