I have attempted to work through the issue with the landlord about another tenant waking me up on daily basis between (12:00am-2am) when they arrive back on the property after work. Their garage is located under my bedroom and they use the remote to lock their car activating the horn. This tenant has also played music loudly, banged their car door on the wall, and began using the garage door which slams closed at night when I try to sleep. Is this a violation of my "Quiet Enjoyment" ? I reside in California, does California Civil Code, § 1927 apply here and can I realistically invoke "Constructive Eviction"? This has been transpiring for three months and continues without a realistic solution from the landlord who I have had numerous conversations with to no avail.
