California law requires landlords to enforce noise provisions in accordance with the city ordinances. Leases often include provisions about excessive noise, which allows landlords to issue warnings to noisemakers, as well as evict tenants who repeatedly violate the noise rules. If you are bothered by excessive noise from other tenants, write a letter to your landlord detailing the problem. Describe the type of noise, time of day it's occurring, and its frequency. Your landlord is legally responsibility to protect your right to quiet enjoyment of the rental property。
Police Enforcement
When your neighbors insist on ignoring the landlord's request to control the noise, you and the landlord can call the police. Law enforcement officials are responsible for monitoring and notifying people who are disturbing the peace. In certain cities, a violation of the noise ordinance is a misdemeanor, and officers will respond quickly if you issue a complaint. Document any incidences that involve the police, and send a copy to your landlord. If you seek to break your lease because of excessive noise, documentation will back up your claims.
Lease Termination
If your landlord ignores your complaints about excessive noise, you can terminate your lease with proper notice under California Civil Code 1942. You're required to give a written, 30-day notice to the landlord outlining the reasons for leaving. You cannot legally break your lease if the landlord doesn't know anything about the problem or if he's making an effort to remedy it. Also, you cannot break the lease if the landlord is in the process of evicting the noisy tenants.
