Hello,

When I decided to use your service, I thought those were the questions that you would answer. Are they too involved to answer?

No, but it is just that one does not need to get that specificity - we law that I provided suits just fine.

Has the issue of low frequency noise and its impact on home environment and health of condo residents sharing a common wall been litigated ?

No - nothing specifically that discusses a shared wall that has set a strong precedent.

Has any case related to sub woofers and their impact on condo residents been litigated?

No - nothing that sets precedent.

Is there a law that insures individual owners of a condo duplex have equal rights to a peaceful home environment?

Not owners of a condominium specifically - there is no difference between owners of a condo, tenants, or owners of a home when it comes to this matter. Ergo, the overall law applies.

As stated above, I live in Chula Vista, not San Diego. We have different municipal codes.

Apologies, I thought I was using San Diego's county code, but that is San Diego municipal code. Chula Vista is below:

As you can see, the same answer applies. See below with slight modification:

CRIMINAL
CA leaves it up to localities to define their own sound ordinances. Chula Visat'a Noise Ordinance are below:

http://docs.sandiego.gov/municode/MuniCodeChapter05/Ch05Art9.5Division04.pdf

If at any time you feel that they are breaching that noise ordinance, you may call the police. If the police feel that the sound is indeed over the limit, these individuals will be given criminal summons, or at least warned. It is better to have more than one neighbor complain at once in such instances.

CIVIL
With or without the criminal aspect, you may seek civil relief and file a petition for the following - nuisance and negligence per se.

A nuisance is broadly defined as "[a]nything which is injurious to health, or is indecent or offensive to the senses, or an obstruction to the free use of property, so as to interfere with the comfortable enjoyment of life or property...." (Civ. Code, § 3479).

Negligence per se is defined as (1) the defendant violated a statute, ordinance, or regulation of a public entity; (2) the violation proximately caused death or injury to person or property; (3) the death or injury resulted from an occurrence the nature of which the statute, ordinance, or regulation was designed to prevent; and (4) the person suffering the death or the injury to his person or property was one of the class of persons for whose protection the statute, ordinance, or regulation was adopted. (Spates v. Dameron Hosp. Assn. (2003) 114 Cal.App.4th 208, 218, 7 Cal.Rptr.3d 597.)

(Depending on specific definition of injury, this may be negligence or negligence per se that is applicable.)

California Civil Code § 3294 allows punitive damages in cases of malice.

Often, a good thing to do is perhaps a cease and desist letter from an attorney to them, threatening to sue for the above. Normally, this helps to take care of the matter without having to litigate.

I hope this finds you well.
