Los Angeles FAQ
Can my neighbor be cited if I hear them through the wall?
Yes. LAMC uses a plainly-audible standard at the property line during night hours, and LAPD can issue citations without a formal sound meter reading when violations are clear.
How do I report a noise violation?
Call LA 311 for non-emergency noise complaints or LAPD non-emergency dispatch for active disturbances. Persistent issues can be referred to the Bureau of Street Services.
