The City of Alhambra limits exterior noise in residential neighborhoods from a maximum of
55 dBA (7 a.m. to 10 p.m.) to 50 dBA (10 p.m. to 7 a.m.). Interior noise is likewise regulated
in residential neighborhoods from a maximum of 50 dBA (7 a.m. to 10 p.m.) to 45 dBA
(10 p.m. to 7 a.m.). Noise standards also exist for commercial and industrial zones. 
(TITLE XVIII: Community Noise & Vibration )

Standards apply to noise nuisance created by vibration and barking dogs:

• Alarm Systems: The Police Chief may discontinue response by city officers to an alarm after there are more than six false alarm assessments against a specific location in a calendar year. Per California Vehicle Code, Section 22651.5, a police officer may, upon complaint, remove a vehicle if the vehicle theft alarm system has been activated for 20 minutes after the officer’s arrival, and the alarm has not silenced within that time. (TITLE IX: Public Peace & Safety, Chapter 9.74 Alarm Systems)
   
• Barking Dogs: It is unlawful for an owner to keep, maintain or harbor a dog that disturbs the peace and quiet of the neighborhood by loud barking. Owners may only keep two domestic dogs per household. Dogs may not run around at large in the neighborhood. (TITLE XVII: ANIMALS, Chapter 7.20.150 Loud Barking; TITLE XVII: ANIMALS, Chapter 7.20.120 Keeping More than Two Dogs Prohibited; TITLE XVII: ANIMALS, Chapter 7.20.158 Dogs Restrained from Running at Large)

TIPS TO KEEP DOGS FROM BARKING

Dogs bark excessively for numerous reasons such as loneliness, frustration, frequent
neighborhood activity, hyperactivity, etc. The following suggestions may be helpful in
controlling excessive barking:

• Give the dog attention and exercise daily.
   
• If the dog barks because of frequent neighborhood activity, try to remove the dog
  from the activity by possibly keeping the dog in the house or garage, or other
  location isolated from the source of disturbance.
   
• Dogs frequently bark while left outside alone on the property. If you must leave the
  dog unattended, keep the dog inside the garage or house whenever possible.
   
• Consult your veterinarian on the possible causes for the barking.
   
• Explore training services listed in the Yellow Pages under "Dog Training."
   
• Try using Citronella Spray as a way to train your dog not to bark. Many vets
  recommend this type of product because it is not harmful to the dog. Because all
  dogs hate citrus, the use of this spray, which is harmless and non-toxic, will help
  train the dog not to bark.
