Police vs. code enforcement
Yes, in the right situations. For serious disturbances — especially loud noise during nighttime quiet hours — local police can sometimes respond to an active noise complaint, and many cities have noise ordinances that set legal limits.
Police response is generally best suited to immediate, serious disturbances happening right now, like a loud late-night party. For ongoing patterns, such as repeated daytime construction noise or a chronic problem, a city or county code-enforcement or noise office may be the better route, because they handle ordinance violations and can cite the responsible party.
Local noise ordinances vary, but many restrict excessive or unreasonable noise and set stricter limits overnight. Reporting violations creates an official record, which can also support your complaints to the landlord.
Using these public tools does not replace notifying your landlord when the source is another of the landlord's tenants — often you will use both. If you have documented the problem and official complaints have not resolved it, a free, confidential review can help you understand what further options may exist.
