How Santa Ana Handles Noise Ordinances: A Practical Guide

Santa Ana maintains 217 local ordinances across all categories, and 9 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Santa Ana falls on the strict-to-permissive spectrum compared to other cities.

Barking Dogs

Santa Ana declares persistently barking dogs a public nuisance under SAMC Sec. 5-59.1. A dog barking incessantly for 30 minutes or intermittently for 60 minutes in any 24-hour period constitutes a violation. Complaints are filed with the Santa Ana Police Department.

Key details: Threshold: 30 min continuous / 60 min intermittent. Warning Period: 10 days. Complaints To: Santa Ana Police Dept.. Code Section: Sec. 5-59.1.

Administrative citation after 10-day warning. Progressive fines for continued violations. Criminal prosecution or civil action may be pursued for persistent non-compliance.

This is not one of those rules that cities tend to ignore. Santa Ana actively enforces its barking dogs requirements.
